Description:

Abstract: These metadata are specifically for the State of Rhode Island,
one state in the national compilation of state geologic map databases.
The digital geologic state map data was prepared by the Rhode Island
Geological Survey in 1994. Subsequent editing of the spatial data by the
USGS was limited to fitting a standardized state boundary to the data,
standardizing the arc coding, reprojecting the data, and minor edits of
arc or polygon attributes to conform with the paper map.

This open-file report is one of several that present the preliminary
results of the USGS Mineral Resources Program activity to compile a
national-scale geologic map database to support national and regional
level projects, including mineral resource and geoenvironmental
assessments. The only comprehensive sources of regional- and
national-scale geologic maps are state geologic maps with scales ranging
from 1:100,000 to 1:1,000,000. Digital versions of these state maps form
the core of what is presented here. Because no adequate geologic map
exists for the state of Alaska, it is being compiled in regional blocks
that also form part of this national database. It is expected that this
series will completed by approximately the end of 2007. These maps and
databases are being released in blocks of states or, in the case of
Alaska, as compiled blocks of 1:250,000-scale quadrangles as chapters in
this series. For Alaska, formal maps as well as databases are being
published here, whereas for the conterminous U.S. only state databases
and preview graphics are presented, because published maps for most
states already exist. For Alaska these regional compilations will form
the base for compiling a new geologic map of the state. As documented in
CONUSdocumentationNENJ.pdf, standards for the conterminous U.S. are
somewhat different than those for Alaska and Hawaii.

Purpose: A primary goal of this work is to develop geologic map datasets
with standardized structure and attribution. The database design and
standards are documented in CONUSdocumentationNENJ.pdf of this series.
The intent is that contiguous databases can be merged seamlessly and
without any additional effort. In addition to a common database
structure, the conterminous U.S. state databases (the contiguous 48
states) have been fitted to a set of standard state boundaries so that,
when states are merged, they match without slivers or overlap. No
attempt has been made to reconcile differences in mapping across state
boundaries.

Supplemental_Information:

This database consists of up to five major Arc/Info GIS datasets for
each state;

\- one: geologic map with formations,

\- two: faults (where present),

\- three: dikes (where present),

\- four: miscellaneous line features (where present),

\- five: miscellaneous point features (where present).

Data_Quality_Information:

Attribute_Accuracy:

Attribute_Accuracy_Report: The values of the attributes ROCKTYPE1 and
ROCKTYPE2 were assigned based on the information in the legends of the
source maps (most of which are paper). The definitions of these values
are described in the draft document Geologic Map Classification version
6.1 (Johnson and others); available at the following website:
http://geology.usgs.gov/dm

Logical_Consistency_Report: All internal polygons were checked for
closure with vendor software and on hard copy plots. Overshoots and
undershoots have been deleted or corrected as appropriate.

Completeness_Report: Bodies of water are classified as water, and the
geologic units underlying them are not included in this coverage.

Positional_Accuracy:

Horizontal_Positional_Accuracy:

Horizontal_Positional_Accuracy_Report:

Accuracy of Rhode Island state boundary and those arcs intersecting it:
The accuracy of the state boundary arcs is based on the 1:100,000 scale
original data used to produce this boundary. (Johnson, Bruce R. and
Leveritch, Beth, 1998, 1:100,000 Scale State Boundaries of the
Conterminous United States: U.S. Geological Survey, unpublished (see
metadata file: st100kmeta.txt, CONUSdocumentationNENJ.pdf))

Those internal arcs intersecting the state boundary were extended or
shortened as needed to complete polygons, possibly creating a small
amount of error.

Process_Step:

Process_Description: The purpose of this standardization is to allow all
SGMC covers to be seamlessly joined without any additional effort to
form regional or national level digital maps. Note that for Alaska, the
state is being compiled as blocks of 1:250k quadrangles that will
ultimately be used to compile a new state map. Douglas Stoeser (USGS)
and Ric Wilson (USGS) are co-coordinators for the overall SGMC effort,
with Stoeser coordinating work on the mainland states and Wilson
coordinating work for Alaska and Hawaii.

Process_Date: 2003 - 2006

Process_Step:

Process_Description:

C.L. Dicken obtained the digital geologic map of Rhode Island from Rhode
Island Geographic Information System,
http://www.edc.uri.edu/rigis-spf/Statewide/state.html#geology. The
coverage was re-projected into the following:

projection: Lambert Conformal Conic

units: meters

datum: NAD27

standard parallel 1: 33 0 0.000

standard parallel 2: 45 0 0.000

central meridian: -100 0 0.000

reference latitude: 0 0 0.000

false easting: 0.00000

false northing: 0.00000

(Note: Attributes associated with the generation of the coverages were
not deleted.

PAT - shape, area, perimeter, coverage#, and coverage-id

AAT - shape, fnode#, tnode#, lnode#, rnode#, length, coverage#, and
coverage-id)

All attributes were deleted except unit_label.

The values from unit_label where then calculated into a new field called
orig_label.

Process_Date: 2006

Process_Step:

Process_Description:

The relevant state outline (arcs) was removed from the coverage and
replaced with the arcs from the 1:100,000 Scale State Boundaries of the
Conterminous United States.

This allows for a seamless fit of each state to a standard state
boundary base.

Process_Date: 2006

Process_Step:

Process_Description:

The following attributes were exported from Filemaker as a .dbf:

orig_label, map_symbol2, unit_link, reference_id, unit_age, rocktype1,
and rocktype2.

orig_label reflects the original map symbol used on the source map

map_symbol2 reflects map-symbol1 with the addition of a province number

unit_link is an auto generated field based on map-symbol2 and the state
abbreviation (e.g. RI001) that produces a unique identifier for each map
unit

reference_id was populated with an alphanumeric code (e.g. US001) that
designates the source used for the linework and other references used to
describe the age or lithologies of the unit.

unit_age was populated with general age assignment

rocktype1 records dominant lithology (does not imply minimum percentage
of abundance), using standardized data dictionary

rocktype2 records second most dominant lithology, using standardized
data dictionary

The attributes were then converted using the following structure:

item name: orig_label

width: 12

output: 12

type: c

item name: sgmc_label

width: 16

output: 16

type: c

item name: unit_link

width: 18

output: 18

type: c

item name: source

width: 6

output: 8

type: c

item name: unit_age

width: 60

output: 60

type: c

item name: rocktype1

width: 40

output: 40

type: c

item name: rocktype2

width: 40

output: 40

type: c

Process_Date: 2006

Process_Step:

Process_Description: Once the .dbf was in the correct format with
standardized column widths and data structure, it was converted into a
lookup table (.lut) in Arc/Info. Then a joinitem was performed to join
the look-up table to the polygon attribute table. orig_label was used as
the merge item.

Process_Date: 2006

Process_Step:

Process_Description:

Next, in preparing the uniform .aat file, the following items were added
to the table:

item name: arc-code

width: 3

output: 3

type: i

item name: arc-para1

width: 3

output: 3

type: i

item name: arc-para2

width: 3

output: 3

type: i

item name: source

width: 6

output: 8

type: c

Process_Date: 2006

Process_Step:

Process_Description:

Arc-code was populated using the paper map source to tag the lines using
the AAT line type data dictionary (see CONUSdocumentationNENJ.pdf in
this series).

Arc-para1 was populated when additional information was available such
as identifying the upthrown side of a fault or direction of thrusting on
a fault. (see CONUSdocumentationNENJ.pdf)

Arc-para2 is a scratch field that is used mostly in Alaska.

Source was populated with an alphanumeric code (e.g. US001) that
designates the source used for the linework.

Process_Date: 2006

Process_Step:

Process_Description:

Once the .aat and the .pat were populated with the correct attributes,
the coverage was exported as an .e00 file (RIgeol_lcc.e00).

Then it was unprojected into geographic coordinates and exported again
(RIgeol_dd.e00).

Process_Date: 2006

Process_Step:

Process_Description: Faults were extracted from the coverage and created
a separate fault coverage (RIfaults_lcc) and then exported
(RIfaults_lcc.e00).

Process_Date: 2006

Process_Step:

Process_Description: Finally, the geology lines, geology polygons and
faults were converted into shapefiles; in both geographic coordinates
and in Lambert Conformal Conic projection.
