Great Lakes and St. Lawrence River Medium Resolution Vector Shoreline Data1

Deborah H. Lee, Charles Morse, and Sameer Bandhu

ABSTRACT. Digital medium-resolution vector maps of the Great Lakes and St. Lawrence River

shoreline are compiled by the Great Lakes Environmental Research Laboratory (GLERL), and translated into multiple common formats including the Topological Vector Profile of the Spatial Data

Transfer Standard (SDTS), to enhance data accessibility. The data were originally produced by the

Detroit District, U.S. Army Corps of Engineers and Water Issues Division of Environment Canada -

Ontario Region for the International Joint Commission’s Levels Reference Study, and used to assess

the influence of lake levels on shore erosion. The vector maps include a three tier classification

representing the shoreline geomorphic nature, the extent of shoreline protection, and the nearshore

subaqueous geomorphic nature. Metadata, documented in accordance with SDTS specifications,

accompanies the digital maps. This work was done in conjunction with the National Geophysical

Data Center to develop medium resolution vector coastline data for the conterminous United States,

and was funded by NOAA's Earth System Data and Information Management Program. Potential

exists for use of the data in shoreline management and environmental and coastal processes studies.

1. INTRODUCTION

The development of geographic information system (GIS) technology now allows the digital manipulation and

compilation of complex spatial datasets. However, proprietary data formats of commercial GIS software has

limited the portability of datasets from their originators to other potential users. In recognition of this problem,

the National Committee for Digital Cartographic Data Standards and the Standards Working Group of the Federal

Interagency Coordinating Committee on Digital Cartography proposed the Spatial Data Transfer Standard

(SDTS). After considerable review and testing, the standards were published as Federal Information Processing

Standard (FIPS) 173 in 1992 (National Institute of Standards and Technology, 1992). The SDTS forms the

cornerstone of the National Spatial Data Infrastructure (NSDI), created by Executive Order dated April 11, 1994.

The NSDI requires all federal agencies to produce new, and to the extent practicable, existing geospatial data

using the SDTS.

The Great Lakes Environmental Research Laboratory (GLERL), in conjunction with the National Geophysical

Data Center, was funded by NOAA's Earth System Data and Information Management Program to produce

medium resolution vector coastline data for the conterminous United States using the SDTS. This technical

memorandum documents GLERL’s compilation and translation of the Great Lakes and St. Lawrence River

shoreline data to SDTS and other common formats.

2. GREAT LAKES-ST. LAWRENCE RIVER VECTOR SHORELINE DATA

The Great Lakes-St. Lawrence River shoreline (American and Canadian) was mapped and classified in support of

the International Joint Commission’s Levels Reference Study to assist in quantifying the effect of lake levels on

erosion (Working Committee 2, 1993). A three tier classification scheme was used as shown in Table 1. The first

tier classifies the shoreline by its geomorphic nature, the second tier by the percent of shore protection, and the

third tier by the nearshore subaqueous type. The American shoreline was delineated based on aerial photography,

mapped at a scale of 1:24,000, and was classified by the U.S. Army Corps of Engineers (United States Army

Corps of Engineers, 1992). The Canadian shoreline was mapped by digitizing 1:50,000 scale National Topographic Series (NTS) maps for the lower Great Lakes, and 1:250,000 NTS maps for upper Lake Huron and Lake

Superior, and was classified by Geomatics International for Environment Canada (Geomatics International, 1992).

Figures 1-4 illustrate the mapped data for selected locations.

Because these datasets resided in separate locations in different proprietary geographic information system

formats, the complete database was not readily available to users. The Great Lakes Environmental Research

Laboratory was uniquely positioned to create the unified database for distribution and archival because of established working relationships with all parties, the resources and experience of their geographic information system

laboratory, and NOAA's desire to create medium resolution vector coastline data for the conterminous United

States.

GLERL obtained the data from the Detroit District, U.S. Army Corps of Engineers and Water Issues Division of

Environment Canada - Ontario Region and translated the data into the Topological Vector Profile of the Spatial

Data Transfer Standard, as well as Arc/Info export and ASCII formats. To further enhance compatibility, the data

were transformed from various projections to one common projection, Albers Equal Area, and also into geographic coordinates. The procedures used are detailed in the metadata found in Appendix A. The metadata were

compiled in accordance with the Federal Geographic Data Committee’s Content Standards for Digital Geospatial

Metadata (Federal Geographic Data Committee, 1994).

3. DATA AVAILABILITY

The data are available to users via anonymous ftp over the Internet from GLERL's anonymous ftp site,

ftp.glerl.noaa.gov. GLERL's ftp site can also be accessed from GLERL's web page, www.glerl.noaa.gov. The

Combined Classification:

The above codes are appended into a 3 to 4 digit code representing the combined classification. The

right-most digit represents the nearshore subaqueous classification, the second digit from the right represents

the shoreline protection classification, and the left-most one or two digits represent the shoreline geomorphic

classification.

Purpose:

The shoreline vectors and classification scheme were originally developed by Environment Canada and the

U.S. Army Corps of Engineers to evaluate the influence of lake level effects on erosion for the International

Joint Commission's Levels Reference Study. Potential exists for use of the data in shoreline management, and

environmental and coastal processes studies.

Revisions: None

Reviews_Applied_to_Data:

The U.S. data were received from the U.S. Army Corps of Engineers, Detroit District. After conversion by

GLERL of the data from INTERGRAPH vector format to the ARC/INFO vector format (see Procedures

Used), the vector data were checked to ensure consistent topology. Visual inspection of the processed data

overlaying the original data and other shoreline datasets was used to check for any gross processing errors.

Shoreline classification codes in the processed U.S. data were verified manually by comparing computer and

hard copy maps to hard copy maps provided by the Detroit District. Reviews applied during the production of

the data by the originators are described in the references listed below (see Other References Cited).

The Canadian data was received from the Water Issues Division of Environment Canada, Ontario Region, in

Arc/Info vector format. After modifying attribute item definitions and appending the attribute information to

the vector files (see Procedures Used), the processed data were visually inspected as described above and the

classification codes were verified by comparing computer and hard copy maps to hard copy maps provided by

Environment Canada. Reviews applied during the production of the data by the originators are described in

the references cited below (see Other References Cited).

Time_Period_of_Content:

Calendar_Date: Unknown

Currentness_Reference:

The aerial photography used to generate the U.S. shoreline vector data was acquired in 1979 for the State of

Michigan and in 1987-1989 for the other seven Great Lakes. The time period of content for the Canadian

shoreline vector data is unknown to the compiler.

The U.S. and Canadian shoreline classification was completed in 1992 from a variety of variously dated

materials. The shoreline protection classification may change significantly as time increases from the date of

the original classification. More information on the currentness of the vector and classification data is contained in the references cited above (see Other References Cited).

Access_Constraints:

There are no access constraints on the U.S. data. Unlimited use and reference of the Canadian shoreline data

is granted upon condition that Water Issues Division of Environment Canada - Ontario Region is credited as

the source.

Data_Set_Credit:

The data were originally produced by the U.S. Army Corps of Engineers and Environment Canada for the

International Joint Commission’s Levels Reference Study, Great Lakes-St. Lawrence River Basin, by Working

Committee 2, Land Use and Management, and used to assess the influence of lake levels on shore erosion.

The U.S. shoreline data were obtained from the Detroit District, U.S. Army Corps of Engineers, Detroit,

Michigan. The Canadian shoreline data were obtained from Water Issues Division of Environment Canada -

Ontario Region. The Great Lakes Environmental Research Laboratory, Ann Arbor, Michigan compiled the

data and translated them into multiple common formats including the Topological Vector Profile of the Spatial

Data Transfer Standard, to enhance the accessibility of the data. This work was done in conjunction with the

National Geophysical Data Center to develop medium resolution coastline data for the conterminous United

States, and was funded by NOAA's Earth System Data and Information Management Program.

Completeness_Report:

The data include vector representations of the Great Lakes shoreline, their connecting channels, the St.

Lawrence River, and many (but not all) islands. Some man-made features such as the Keweenaw Waterway

(Lake Superior) are excluded. The vector end-nodes of some of the U.S. counties and Canadian regions are

not consistent with their adjacent county or region. Most of the shoreline is classified with the exception of

most islands, Isle Royale (Lake Superior) being a notable exception.

Use_Constraints:

Vector Shoreline:

The vector data are intended for general planning, study, and illustrative purposes. The data are not intended

for uses that require a high degree of positional accuracy.

Shoreline classification:

The process of shoreline classification was essentially subjective and based almost entirely upon descriptive

criteria. The classification of each reach was the result of the subjective interpretation of the individual doing

the work and was based on their understanding of the classification scheme, the information available, and the

experience of the individual. The shoreline protection classification may change significantly as time increases from the date of the original classification. Other limitations are the inadequacy of the classification

scheme to encompass the complete range of shoreline characteristics, and insufficient detail of the data

sources to permit classification. Inconsistencies in classification may exist.

Procedures_Used:

U.S. Data:

INTERGRAPH format shoreline files, by U.S. county, were obtained from the Detroit District U.S. Army

Corps of Engineers ftp server, ftp://ftp@155.79.125.194/pub/. These files were stored on the HP 735/9000

GIS workstation at the Great Lakes Environmental Research Laboratory. The procedures used to convert and

process a given INTERGRAPH file were essentially the same for all of the counties: a file was converted to

two ARC/INFO vector format covers--one for the shorelines and one for the breaklines (hash marks that

intersect the shorelines at the reach endpoints)--using the ARC command IGDSARC with the subcommand
19

shoreline 61 * * * * for shorelines and break 3 * * * * for breaklines. ARC attribute tables (AAT), in INFO

format, were then generated for the shoreline and breakline covers using the ARC command BUILD with the

line option. Next, the shoreline and breakline covers that were generated from the same INTERGRAPH file

were appended together using the ARC command APPEND. An AAT was then built for the resulting appended cover using BUILD with the line option.

 Canadian Data:

The Canadian data were obtained from Waters Issue Division, Environment Canada in ARC/INFO format.

Some of these covers had items which were dropped from the covers’ associated arc attribute tables. These

items included PLOTKEY, REACHKEY, ITEM2, and ITEM1. This was done to prepare the AAT files before

joining the INFO tables that contained the shoreline classification codes. The items in these tables included

REACH_KEY, GEOMORF, PROTECTION, and NEARSHORE. The item GEOMORF was altered to spell

GEOMORPH. Then these tables were joined to each shoreline cover’s AAT using the ARC/INFO command,

JOINITEM, specifying the cover-id item in the AAT as the relate item and using the LINK option. This

process placed the Canadian data in the same format as the U.S. shoreline data.

 U.S. and Canadian Data:

The covers were projected from their original projections and map coordinate systems to Albers Equal-Area

Conic. This was done by using the ARC command PROJECT with the cover option and the appropriate input

and output parameters, listed below. Note that for Michigan county shoreline covers, which were in the

Michigan State Plane Coordinate System prior to projecting to Albers, ARC software permitted specifying

“stateplane” for the projection, instead of specifying an actual projection and projection parameters. When

stateplane is entered, the user is prompted for a FIPS code zone number (FIPSZONE). FIPSZONE numbers

were determined from Table 4 in the ARC command reference for the PROJECT command. The

FIPSZONES entered were 2111, 2112, and 2113 (North, Central, and Southern Michigan, respectively).

 U.S. Data:

The U.S. covers, when first converted from INTERGRAPH to ARC, had pseudonodes at every vertex. Thus,

arc segments were very short and did not extend across the reach from one breakline to another. After projection to Albers Equal Area, the ARC command CLEAN was used to establish arc-node topology so that

pseudo-nodes could be removed. The covers were processed using CLEAN with the line option, a dangle

length of 0, and a fuzzy tolerance of 2 meters. The coordinate precision of the U.S. covers remained double

precision. All covers were CLEANed only once. All pseudo-nodes were then removed by selecting all arcs

using the ARC module ARCEDIT and then using the ARCEDIT command UNSPLIT with the none option.

Changes to the edit coverage were saved and ARCEDIT was quit.

AATs were rebuilt using BUILD with the line option. Then ARCEDIT was again launched and a coverage

chosen for editing. All arcs were selected, and the user-id (<cover>-id) was reset to equal the internal-id

(<cover>#) using the ARCEDIT command CALCULATE. Then the items GEOMORPH, PROTECTION,

NEARSHORE, and COMBINED were added to the AAT using the ARCEDIT command ADDITEM with

input and output width of 4 and data type integer.

A graphical user interface was created to simplify the editing and coding of arcs. Arcs were selected and

edited using ARCEDIT commands such as DELETE and UNSPLIT and coded using CALCULATE. Codes

for the COMBINED item were determined from hardcopy maps generated from the original INTERGRAPH

files, obtained from the Detroit District U.S. Army Corps of Engineers. An algorithm was developed to parse

the COMBINED code into GEOMORPH, PROTECTION, and NEARSHORE values and automatically

update these item values whenever a COMBINED code was entered for a selected arc. Arcs whose codes

were ambiguous were given a combined value of 9999, which was also parsed, giving 99, 9, and 9 for the

three classifications. All arcs representing breaklines were deleted, leaving only pseudonodes to mark the

point along the shoreline where reaches end. In some cases, pseudo-nodes could not be removed (because

ARC limits the number of vertices in an arc to 500). These pseudonodes can be distinguished from

breakpoints because the codes of the adjoining arcs are the same.

 U.S. and Canadian Data:

All covers in the Albers Equal Area projection were converted to ARC/INFO export files using the ARC

command EXPORT with the COVER and FULL options. The covers were also converted to ASCII generate

format files using the ARC command UNGENERATE with the LINE option. The companion INFO AAT

tables were converted to comma delimited ASCII files using the ARC TABLES command UNLOAD with the
22

DELIMITED option. The covers were also projected and the same process used to create ASCII

UNGENERATE files in geographic coordinates. To build polygon topology for conversion to SDTS, the

covers projected to geographic coordinates were processed using the ARC command BUILD with the POLY

option. These covers were then converted to SDTS Vector Topological Profile files using the ARC command

SDTSEXPORT.
