THE RHODE ISLAND RESOURCE PROTECTION PROJECT GIS DATA LAYERS

The Rhode Island Resource Protection Project developed a series of GIS data that detail statewide resources. The following tables provide a complete description of the data layers used by the project. This information is intended for planning purposes only; please contact the agency listed as "Data Source" if you have any questions about the information.

GIS Listing

ARC/INFO Export File Dataset Metadata Export File Size (KB's) Dataset Description

eelgrass.zip eelgrass.txt 8 Eelgrass beds of Rhode Island

fish_run.zip fish_run.txt 476 Anadromous fish runs of Rhode Island

fishladr.zip fishladr.txt 18 Dams with or without Fish ladders

fishzone.zip fishzone.txt 1,524 Fishery concentration zones for the purposes of the RI Resource Protection Project were considered to be near coastal waters less than 20m deep.

flounder.zip flounder.txt 1,049 Winter flounder spawning area in Rhode Island

heron.zip heron.txt 68 Nest sites of Narragansett Bay, RI / MA. This coverage contains points located on all the nest sites and bird colonies included in this study. Some arcs and annotation added for display purposes. Complete descriptions for all the codes found in the coverage items can be found in the final report, Habitat Inventory / Resource Mapping for Narragansett Bay and Associated Coastline.

landmark.zip landmark.txt 13 National natural landmarks of Rhode Island. National natural landmarks are designated by the National Park Service.

lgwetlnd.zip lgwetlnd.txt 20,396 Large and complex wetlands of Rhode Island. Wetlands greater than 1 acre in Wetlands greater than 1 acre in size were considered for analysis. Wetlands were ranked using criteria involving size, class diversity, surface water connections, surrounding habitat types, and proximity to other wetlands. This calculation is fairly complex and is explained further on the Habitat Resources map produced by the RI Resource Protection Project. Wetlands with a total rank greater than 14 were considered to be `large and complex wetlands'. This data is for planning purposes only; it has no legal significance for any regulatory purposes and has not been adopted by RIDEM. The development of all wetlands, regardless of size is regulated by state and federal agencies.

migrate.zip migrate.txt 77 Winter flounder and tautog migratory routes in Rhode Island

osprey.zip osprey.txt 17 Osprey nesting sites in Rhode Island

seal.zip seal.txt 14 Seal haulout sites of Rhode Island

shelfish.zip shelfish.txt 753 Shellfish beds of Rhode Island

tautog.zip tautog.txt 907 Tautog spawning areas of Rhode Island

uncoast.zip uncoast.txt 721 Undeveloped coastline of Rhode Island. USGS 1:24,000 hydrologic data, 1988 landuse data, and 1990 Census data were used to identify undeveloped coastlines. Coastlines (90m wide) with 100% natural land and at least 500m in length were considered to be undeveloped coastlines.

unfrglnd.zip unfrglnd.txt 3,521 Unfragmented lands of Rhode Island. USGS 1:24,000 road coverages were used to define the boundaries of land blocks. Blocks of land with population density less than 40 persons per square km were used in this analysis. The percentage of natural land for each block was calculated. Natural land information was derived from 1988 landuse data, and includes forest, idle agricultural land, and wetlands. The land use data were delineated from 1:24,000 scale stereo aerial photography.

unhydro.zip unhydro.txt 5,008 Undeveloped riverbanks and lake shorelines of Rhode Island. USGS 1:24,000 hydrologic data, 1988 landuse data, and 1990 Census data were used to identify undeveloped riverbanks and lake shorelines. River banks and lake shorelines with less than 40 persons per square km, 100% natural land, and at least 500m in length were considered to be undeveloped coastlines.

waterbrd.zip waterbrd.txt 38 Areas of Rhode Island that support large concentrations of waterfowl during the migration period
