Abstract:
This data set contains polygon features of existing environmental corridors and isolated natural resource areas for the seven county Southeastern Wisconsin Region. The polygon features were delineated on land use inventory maps, with reference to 1"=400' scale aerial photographs, and digitized from these source materials. The data set was collected at 5-year intervals, and is current for the years 1990, 1995, and 2000. The polygons consist of primary and secondary environmental corridor areas and isolated natural resource areas as defined by the Southeastern Wisconsin Regional Planning Commission (SEWRPC).
Purpose:
This data set was collected to provide an inventory of environmental corridors and isolated natural resource areas in Southeastern Wisconsin, and to be used for broad regional planning purposes.

Access_Constraints:
There are no legal prerequisites for accessing this data set. Potential users should contact the Southeastern Wisconsin Regional Planning Commission GIS Division.
Use_Constraints:
This data set was prepared from aerial photography and land use maps acquired at approximately 5-year intervals. The most recent inventory may not reflect current environmental corridor conditions. Site investigation may be necessary to determine current type and extent of environmental corridors.


2.  Data_Quality_Information:

Logical_Consistency_Report:
The polygon features in this data set were collected by board digitization of information collected from 1"=400' scale aerial photographs and similar scale hardcopy land use maps. Portions of the 1990, 1995, and 2000 environmental corridor inventories have been adjusted to fit large-scale cadastral maps where such mapping has been completed. The features were verified with software routines to insure completeness and integrity of lines and areas. The data set contains lines that intersect where intended, there are no lines that are entered twice, there are no overshoots or undershoots, and all areas are completely described. The area features are topologically structured polygon data with nodes at all intersections.
Completeness_Report:
This data set was delineated by the Southeastern Wisconsin Regional Planning Commission Land Use Division and digitized by the Commission's GIS Division. The environmental corridor and isolated natural resource area polygons are delineated according to guidelines developed by the Commission staff. To the best knowledge of the Commission GIS Division, this data set includes all of the intended features digitized from the source hardcopy aerial photos and maps.
Positional_Accuracy:
Horizontal_Positional_Accuracy:
Horizontal_Positional_Accuracy_Report:
This data set was collected from hardcopy aerial photographs and hardcopy maps that were prepared to meet National Map Accuracy Standards for one-inch equals 400 feet scale mapping. Therefore, ninety percent or more of all well-defined planimetric features in this data set are within 13.3 feet of their true position on the ground.

5.  Entity_and_Attribute_Information:

Overview_Description:
Entity_and_Attribute_Overview:
This data set consists of a set of inventories covering the years 1990, 1995, and 2000. The digital map files are arranged to cover U. S. Public Land Survey System (USPLSS) townships. The digital files contain environmental corridor polygon features, digitized from land use areas initially delineated on hardcopy products (1"=400' scale aerial photos and maps) for each year of inventory. The 1995 and 2000 inventories contain polygons that have been fitted to large-scale cadastral mapping where such mapping has been completed.

Environmental corridors and isolated natural resource areas consist of the following 12 natural resource and natural resource-related elements: 1) lakes, rivers, and streams and their associated shorelands and floodplains; 2) wetlands; 3) woodlands; 4) prairies; 5) wildlife habitat areas; 6) wet, poorly drained, or organic soils; 7) rugged terrain and high-relief topography; 8) existing park and open space sites; 9) potential park and open space sites; 10) historic sites; 11) significant scenic areas and vistas; and 12) natural and scientific areas. Primary environmental corridors include a wide variety of these resource and resource-related elements and are at least 400 acres in size, two miles in length, and 200 feet in width. Secondary environmental corridors generally connect with primary environmental corridors, and are at least 100 acres in size and one mile in length. Isolated natural resource areas contain some of these resource and resource-related elements, are separated physically from environmental corridors by intensive urban or agricultural land uses, and are at least five acres in size.

The environmental corridor and isolated natural resource area polygons are identified by a tag or label consisting of one of the following codes:

PEC: Primary environmental corridor; SEC: Secondary environmental corridor; INRA: Isolated natural resource area; OUT: Area outside of environmental corridors; 950: Surface water from SEWRPC land use inventory; PEC.950: Surface water inside PEC; SEC.950: Surface water inside SEC; INRA.950: Surface water inside INRA.

The digital map files are in ArcInfo coverage format and ArcView shapefile format. The files consist of graphic map features only and do not contain attributes at this time.

Entity_and_Attribute_Detail_Citation:
Detailed information about environmental corridors and isolated natural resource areas are contained in an article titled "Refining the Delineation of Environmental Corridors in Southeastern Wisconsin" published in the Southeastern Wisconsin Regional Planning Commission Technical Record, Volume 4, Number 2, dated March 1981. Information about the features included in this data set are contained in a document entitled "Environmental Corridor Inventory Digital Map File Data Dictionary" written by the Southeastern Wisconsin Regional Planning Commission GIS Division.
