BOREAS TE-20 Soils Data over the NSA-MSA and Tower Sites in Vector Format
Summary
The BOREAS TE-20 team collected several data sets for use in developing and 
testing models of forest ecosystem dynamics.  This data set contains vector 
layers of soil maps that were received from Dr. Hugo Veldhuis, who did the 
original mapping in the field during 1994.  The vector layers were converted to 
ARC/INFO EXPORT files.  These data cover 1-kilometer diameters around each of 
the NSA tower sites, and another layer covers the NSA-MSA.
Note that some of the data set files on the BOREAS CD-ROMs have been compressed 
using the Gzip program.  See Section 8.2 for details.

1.  Data Set Overview
1.1  Data Set Identification
BOREAS Soils Data over the NSA-MSA and Tower Sites in Vector Format
   
1.2  Data Set Introduction
This data set contains soil properties and classification information over the 
BOReal Ecosystem-Atmosphere Study (BOREAS) Northern Study Area(NSA)-Modeling 
Sub-Area (MSA) and the tower sites.  The data were reprojected into the BOREAS 
Grid system from the original map made by Dr. Hugo Veldhuis (University of 
Manitoba).
1.3  Objective/Purpose
The BOREAS Terrestrial Ecology team #20 (TE-20) collected, processed, and 
delivered the original data to BOREAS Information System (BORIS) personnel.  
This data set has been processed to provide vector files that can be used for 
modeling or for comparison purposes. The purpose of this data set is to provide 
information about the spatial distribution of soils and their characteristics 
over the NSA-MSA and the local areas around the tower sites.
1.4  Summary of Parameters
This data set contains information about the spatial distribution of soil 
classes around the NSA-MSA and tower sites along with soil class properties such 
as parent material, texture, slope class, and water table depth.  A detailed 
list of parameters is given in Section 7.  The polygon numbers in the American 
Standard Code for Information Interchange (ASCII) table files correspond to the 
polygon-ID attribute values in the ARC/INFO EXPORT files.  The value of each 
polygon can link to the table described in Section 7 in order to extract these 
parameters.
1.5  Discussion
This data set was produced as a set of vector layers by Dr. Veldhuis.  Using 
aerial photography and field methods, he identified various soil polygons at a 
scale of 1:50,000 for the NSA-MSA (what Dr. Veldhuis calls the "super site") and 
at 1:5,000 for the tower sites (Old Black Spruce (OBS), Old Jack Pine (OJP), 
Young Jack Pine (YJP), Fen, and Old Aspen (OA)).

3.  Theory of Measurements
The original soils mapping was performed by using a combination of field samples 
of the soil and aerial photographs.  These digital map data provide 
investigators with a continuous surface of soil parameters that can be used for 
modeling purposes.
4.  Equipment
4.1  Sensor/Instrument Description
In addition to field techniques, aerial photography from 1971-73 at a scale of 
1:15,840 was used to map the soils at the tower sites.  Aerial photography taken 
in 1978 at a scale of 1:50,000 was used to map the soils of the NSA-MSA.  No 
additional information is available about this photography.   Please refer to 
the report submitted by Dr. Veldhuis regarding what equipment was used to 
perform the soils mapping.

Units of Measure:  kilometers
7.1.5  Grid Description
These images are projected in the BOREAS Grid system.  The parameters for this 
projection are described in Section 7.1.4.
7.2  Temporal Characteristics
7.2.1  Temporal Coverage
Field samples for mapping the MSA and tower sites were collected in 1994.  
Aerial photos taken in 1978 at a scale of 1:50,000 were used for extending the 
field samples to map the NSA-MSA.  Aerial photos used to map the tower sites 
were taken in 1971 and 1972 at a scale of 1:15,840.

7.3  Data Characteristics
These data are in a vector format in which the polygon-ID value represents the 
polygon number from the original vector data.  This number can be related to a 
record in the ASCII soils table files.  This soils table file contains 
parameters for the various polygons.  There is a separate soils table for each 
map.  In the NSA-MSA soils map, lakes are indicated with a polygon number equal 
to or greater than 5,000.  There is no value in the corresponding soils table 
for these lake polygons.

7.3.2  Variable Description/Definition
Binary Raster Image Files:
POLYNUM: Number of the map polygon to which the pixel belongs.  Unitless but 
coded value.
ASCII Soil Table Files:
1.      POLYNUM = Number of the map polygon.
2.      GRIDLOC = An alphanumeric grid to be used to find a particular polygon 
on the map.
3.      COMPONT = Polygon component (landscape element).
The landscape components that make up the area delineated by the polygon. A 
polygon may have one or many components. They are listed in order of extent.
Code      Class                  Description
----   -----------      -------------------------------------
D      Dominant         The D components combined cover >50% 
                        of the land area of a polygon.
S      Subdominant      The S components combined cover <50% of 
                        the land area of a polygon.
I      Inclusion        Each inclusion covers <15% of the 
                        polygon, but the combined area of 
                        inclusions may be 25%.
W      Water            Surface water in the form of lakes, ponds, 
                        or streams may cover between 5 and 100% of 
                        a polygon. 
4.      NUMBER = Component rank number.
Landscape elements with similar parent material properties are considered to 
belong to the same general component. Thus, these elements together form the 
dominant or subdominant component in the polygon, but the individual elements 
will not be dominant or subdominant. To show the landscape relationship or 
parent material association, the elements are considered to belong to the 
dominant (D) or subdominant (S) group, but are ranked D1, D2, etc., according to 
their relative importance within the group.  For example, three drainage 
conditions exist on a gently undulating glaciolacustrine blanket. The well-
drained portion occupies 30% of the polygon area, imperfectly drained conditions 
exist in 15% of the polygon, and poorly drained areas with a thin peat cover 
occupy an additional 10%, for a combined total of 55%, making this grouping the 
dominant component in the polygon. Thus, these three elements will be labeled 
D1, D2, and D3, respectively.
In the cases of inclusions (I) and water (W), the rank numbers link these 
components either to the dominant or to the subdominant components. The 
convention is that an odd rank number (1,3,5) links the inclusion or water to 
the dominant component(s), while an even rank number links it to the subdominant 
component(s). 
5.      PERCENT = Percentage distribution of components.
Percent area is estimated within the nearest 5%. Components <10% are not listed 
except for W.
6.      KINDMAT = Kind of rock outcrop or other material at the surface.
Code      Class                  Description
-----   ------------            ------------------------------
OR      Organic soil            Contains >30% organic matter by
                                weight
R2      Hard rock, acidic       Granite
SO      Mineral soil            Dominant mineral particles, contains 
                                <30% organic matter by weight
WA      Water                   Water
7.      LANDFRM = Local surface form.
Mineral surface forms. Two classes may be combined; for example, "bh" is 
hummocky blanket, and "vi" is inclined veneer.
Code      Class                  Description

Organic Surface Forms.
The classification of landforms is often the case of "best fit." Often the 
landform encountered does not quite meet all criteria of any class. Organic 
landforms often are intergrades of one form to another.
Code      Class                  Description
-----   ----------            -------------------------------------
Ba      Palsa bog            A bog composed of individual or 
                             coalesced palsas, occurring in an unfrozen 
                             peatland. Palsas are mounds of perennially 
                             frozen peat and mineral soil, up to 5 m 
                             high, with a maximum diameter of 100 m. 
                             The surface is highly uneven, often 
                             containing collapse scar bogs.
Bc      Collapse scar bog    A circular or oval-shaped wet 
                             depression in a perennially frozen 
                             peatland; the collapse scar bog was once 
                             part of the perennially frozen peatland, 
                             but the permafrost thawed, causing the 
                             surface to subside; the depression is poor 
                             in nutrients, as it is not connected to 
                             the minerotrophic fens in which the palsa 
                             or peat plateau occurs.
Bt      Peat plateau bog     A bog composed of perennially frozen 
                             peat, rising abruptly about 1 m from the 
                             surrounding unfrozen fen; the surface is 
                             relatively flat and even, and the bog 
                             commonly covers large areas; the peat was 
                             originally deposited in a nonpermafrost 
                             environment and is associated in many 
                             places with collapse bogs or fens.
Bv      Veneer bog           A bog occurring on gently sloping 
                             terrain underlain by generally 
                             discontinuous permafrost; although 
                             drainage is predominantly below the 
                             surface, overland flow occurs in poorly 
                             defined drainage-ways during peak runoff; 
                             peat thickness is usually less than 1.5 m.
Fb      Basin fen            A fen occupying a topographically 
                             defined basin; however, the basins do not 
                             receive drainage from upstream, and the 
                             fens are thus influenced mainly by local 
                             hydrological conditions; the depth of peat 
                             increases toward the center.
Fc      Collapse scar fen    A fen with circular or oval 
                             depressions, up to 100 m occurring in 
                             larger fens, marking the subsidence of 
                             thawed permafrost peatlands. Dead trees, 
                             remnants of the subsided vegetation of 
                             permafrost peatlands, are often evident.
Fh      Horizontal fen       A fen with a very gently sloping 
                             featureless surface; this fen occupies 
                             broad, often ill-defined depressions, and 
                             may be interconnected with other fens; 
                             peat accumulation is generally uniform.
Fs      Stream fen           A fen located in the main channel or 
                             along the banks of permanent or semi
                             permanent streams. This fen is affected by 
                             the water of the stream at normal and 
                             flood stages.

                             environment because the slightly elevated 
                             nature of the bog dissociates it from 
                             nutrient-rich groundwater or surrounding 
                             mineral soils; near the surface, materials

                             (fibric), yellowish to pale brown, and
                             loose and spongy in consistency, with
                             entire sphagnum plants readily identifiable; 
                             these materials are extremely acid, with 
                             low bulk density and high fiber content; at 
                             depths they become darker, compacted, and 
                             somewhat layered; bogs are associated 
                             with slopes or depressions on topography 
                             with a water table at or near the surface 
                             in the spring and slightly below it during 
                             the rest of the year; they are usually 
                             covered with sphagnum mosses, but sedges 
                             may also grow on them; bogs may be treed 
                             or treeless, and many are characterized 
                             by a layer of ericaceous shrubs.
F      Fluvial               Sediment generally consisting of silt 
                             and clay with a minor fraction of sand and 
                             gravel; gravels are typically rounded; 
                             alluvial sediments are commonly moderately

                             environment because of the close 
                             association of the material with mineral-
                             rich waters; it is usually moderately well

                             lower depths; the materials are covered 
                             with a dominant component of sedges or 
                             brown mosses, but grasses, reeds, sphagnum 
                             mosses, shrubs, and trees may be associated.

VR      Very rapid            Water is removed from the soil very 
                              rapidly in relation to supply; excess 
                              water flows downward very rapidly if 
                              underlying material is pervious; 
                              subsurface flow may be very rapid during 
                              heavy rainfall provided the gradient is 
                              steep; source of water is precipitation.
R       Rapid                 Water is removed from the soil 
                              rapidly in relation to supply; excess 
                              water flows downward if underlying 
                              material is pervious; subsurface flow may 
                              occur on steep gradients during heavy 
                              rainfall; source of water is 
                              precipitation.
W       Well                  Water is removed from the soil 
                              readily but not rapidly; excess water 
                              flows downward readily into underlying 
                              pervious material or laterally as 
                              subsurface flow; these soils commonly 
                              retain optimum amounts of moisture for 
                              plant growth after rains or addition of 
                              irrigation water.
MW      Moderately well       Water is removed from the soil 
                              somewhat slowly in relation to supply; 
                              excess water is removed somewhat slowly 
                              because of low perviousness, shallow water 
                              table, lack of gradient, or some 
                              combination of these; precipitation is the 
                              dominant source of water in medium-to-fine 
                              textured soils; precipitation and 
                              significant additions by subsurface flow 
                              are necessary in coarse textured soils.
I       Imperfect             Water is removed from the soil 
                              sufficiently slowly in relation to supply 
                              to keep the soil wet for a significant 
                              part of the growing season; excess water 
                              moves slowly downward if precipitation is 
                              the major supply; if subsurface water or 
                              groundwater, or both, is the main source, 
                              the flow rate may vary, but the soil 
                              remains wet for a significant part of the 
                              growing season.
P       Poor                  Water is removed so slowly in 
                              relation to supply that the soil remains 
                              wet for a comparatively large part of the 
                              time the soil is not frozen; excess water 
                              is evident in the soil for much of the 
                              time; subsurface flow or groundwater flow, 
                              or both, in addition to precipitation are 
                              the main sources of water; there may also 
                              be a perched water table.
VP      Very poor             Water is removed from the soil so slowly 
                              that the water table remains at or near 
                              the surface for most of the time the soil 
                              is not frozen; groundwater flow and subsurface 
                              flow are the major sources of water; 
                              precipitation is less important except 
                              where there is a perched water table.

c      Cryic                  This designation has been used to 
                              identify Luvisolic soils with permafrost 
                              within the control section. These soils 
                              are at present not recognized in the 
                              Canadian System of Soil Classification.
l      Lithic                 A soil that has a lithic contact 
                              within the control section.
p      Peaty                  A soil that has a peaty layer 15-40 
                              cm thick.
28.      SOILTP1 = Dominant soil type associated with polygon component.
The dominant soil type listed represents the soils that occupy >50% of the 
component. The soil type may be a soil series, which is a soil type defined 
within narrow limits, or a group of soils that vary to some extent in texture, 
depth of profile, etc. The soil type used to identify organic landscape 
components is the soil that best represents the group or complex of soils 
associated with that particular landscape component. The organic soil type 
usually represents related, but sometimes quite different, soils. These 
variations may include peat depth, presence or absence of certain peat layers, 
variation in peat decomposition, etc.
29.      SOILPH1 = Soil phase or variant associated with dominant soil type.
The soil phase or variant is used to identify more specifically the dominant 
soil type. These soils vary to some degree from the model because of differences 
in parent material (stratification, texture), depth of the LFH layer, peaty 
surface, coarse fragment content, etc.

                            concept.
30.      SOILTP2 = Subdominant soil type associated with polygon component.
The subdominant soil type listed represents the soils that occupy <50% of the 
component. The soil type may be a soil series, which is a soil type defined 
within narrow limits, or a group of soils that vary to some extent in texture, 
depth of profile, etc. The soil type used to identify organic landscape 
components is the soil that best represents the group or complex of soils hat 
associated with that particular landscape component. The organic soil type 
usually represents related, but sometimes quite different, soils. These 
variations may include peat depth, presence or absence of certain peat layers, 
variation in peat decomposition, etc.
31.      SOILPH2 = Soil phase or variant associated with subdominant soil type.
The soil phase or variant is used to identify more specifically the subdominant 
soil type component (see no. 29 for codes).
7.3.3  Unit of Measurement
See Section 7.3.2.
7.3.4  Data Source
The original soils mapping was performed by using a combination of field samples 
of the soil and aerial photographs.  These digital map data provide 
investigators with a continuous surface of soil parameters that can be used for 
modeling purposes.
7.3.5  Data Range
Image files:
Each pixel in the image files contains the polygon number value.  This value is 
matched to the polygon number listed in the corresponding ASCII soils table 
file.  The values for that polygon number apply to that polygon.
7.4  Sample Data Record
Sample data records from the binary images are not appropriate here.  The 
following three sample records illustrate how the data are formatted in the 
ASCII soils table files.  Each column is in a fixed-length format.  The column 
labels are written vertically.  Because the records are so long, they are 
presented here in two groups.

8.2.2 Compressed CD-ROM Files
On the BOREAS CD-ROMs, files 1 and 8-13 listed above are stored as ASCII text 
files; however, files 2-7 have been compressed with the Gzip compression program 
(file name *.gz).  These data have been compressed using gzip version 1.2.4 and 
the high compression (-9) option (Copyright (C) 1992-1993 Jean-loup Gailly).  
Gzip (GNU zip) uses the Lempel-Ziv algorithm (Welch, 1994) used in the zip and 
PKZIP programs. The compressed files may be uncompressed using gzip (-d option) 
or gunzip.  Gzip is available from many Web sites (for example, ftp site 
prep.ai.mit.edu/pub/gnu/gzip-*.*) for a variety of operating systems in both 
executable and source code form.  Versions of the decompression software for 
various systems are included on the CD-ROMs.
9. Data Manipulations
9.1  Formulae
9.1.1  Derivation Techniques and Algorithms
The reader is referred to the detailed report submitted by Dr. Veldhuis for 
details on the derivation of the original maps.
9.2  Data Processing Sequence
The data were received from Dr. Veldhuis as DLG files.  These files were read 
into ARC/INFO and EXPORTed as ASCII text files.  These text files were then 
copied to tape.
9.2.1  Processing Steps
BOREAS Information System (BORIS) staff processed these data by:
1.  Reading in DLG files to ARC/INFO.
2.  Ensuring that the polygon topology is accurate.
3.  Writing out coverages to ARC/INFO EXPORT text files.
4.  Copying text files to tape.
5.  Copying the text and compressing the other files for release on CD-ROM.
9.2.2  Processing Changes
None.
9.3  Calculations
9.3.1  Special Corrections/Adjustments
None.
9.3.2  Calculated Variables
None.
9.4  Graphs and Plots
None.
10.  Errors
10.1  Sources of Error
The vector data came from an original mapping using data collected directly from 
the field along with aerial photos.  Errors could arise from a typographical 
error in the field notes.  There could also be a locational error in the maps, 
since the aerial photos that were used were probably not ortho-corrected.  
10.2  Quality Assessment
10.2.1  Data Validation by Source
          
Any data validation or accuracy assessment would have to have been made by the 
original source.  Please refer to the report mentioned in Section 5.
10.2.2  Confidence Level/Accuracy Judgment
The amount of any locational error is unknown, but the data are believed to be 
reasonably accurate for the scale at which they were mapped.
10.2.3  Measurement Error for Parameters
Unknown.
10.2.4  Additional Quality Assessments
None.
10.2.5  Data Verification by Data Center
BORIS personnel viewed and compared the data with the hardcopy map data to 
identify any possible discrepancies.  Some corrections were made to the 
topology, but these were only minor modifications to the data.
11.  Notes
11.1  Limitations of the Data
The report by Dr. Veldhuis may indicate some limitations of the soil mapping.
11.2  Known Problems with the Data
None.
11.3  Usage Guidance
Before uncompressing the Gzip files on CD-ROM, be sure that you have enough disk 
space to hold the uncompressed data files.  Then use the appropriate 
decompression program provided on the CD-ROM for your specific system.
11.4  Other Relevant Information
For more information on this data set, please consult the soils report by Dr. 
Veldhuis.
12.  Application of the Data Set
This data set was created for BOREAS investigators who need soils data in the 
vicinity of the flux towers and the MSA.
13.  Future Modifications and Plans
None.
