Abstract:
This data set contains year 2010 environmental corridors and isolated natural resource areas for the seven-county Southeastern Wisconsin Region. Environmental corridors are areas in the landscape containing especially high value natural, scenic, historic, scientific, and recreational features. The polygon features in this inventory were delineated with reference to a number of Commission data sets, including 2010 Orthophotography, 2005 Environmental Corridor Inventory, 2010 Wisconsin Wetland Inventory, 2010 Land Use Inventory wetlands, and 2005 Natural Areas and Critical Species Habitat Inventories. The primary and secondary environmental corridor areas and isolated natural resource areas were digitized from these source materials by the Southeastern Wisconsin Regional Planning Commission GIS Division.
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 2010 aerial orthophotography with reference to the 2010 Wisconsin Wetland Inventory, 2010 Land Use Inventory, and 2005 Environmental Corridor Inventory as source material. This 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 updating the 2005 Environmental Corridor Inventory, utilizing information from the 2010 Wisconsin Wetland Inventory, 2010 Land Use Inventory, and 2010 orthophotography. 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 Environmental Division, and was digitized by the Commission's GIS Division. The environmental corridor and isolated natural resource area polygons were delineated according to guidelines developed by the Commission staff. To the best knowledge of the Commission's GIS Division, this data set includes all of the intended features digitized from the source hardcopy and digital aerial photos and thematic data sets.
Positional_Accuracy:
Horizontal_Positional_Accuracy:
Horizontal_Positional_Accuracy_Report:
This data set was collected from digital and hardcopy aerial orthophotographs and digital and hardcopy maps that were prepared to meet National Map Accuracy Standards for one-inch equals 200 feet scale mapping. Therefore, ninety percent or more of all well-defined planimetric features in this data set are within 6.6 feet of their true position on the ground.

2010 Environmental Corridor polygon features were delineated and digitized from source materials consisting of the Commission's 2005 Environmental Corridor Inventory, 2010 Wisconsin Wetland Inventory, 2010 Land Use Inventory wetlands, and 2005 Natural Areas and Critical Species Habitat Inventories with reference to 2010 aerial orthophotography

Process_Description:
This data set was collected from various digital map inventories maintained by the Southeastern Wisconsin Regional Planning Commission. The source data sets include 2010 Orthophotography, 2010 Wisconsin Wetland Inventory, 2010 Land Use Inventory, and 2005 Natural Areas and Critical Species Habitat Inventories. Hardcopy plots at 1" = 400' scale were prepared showing the boundaries of wetlands, corridors, natural areas, and critical species habitat sites on 2010 orthophotography. The hardcopy plots were delineated by the Commission's Environmental and Land Use Divisions to show the boundaries of 2010 primary environmental corridors, secondary environmental corridors, and isolated natural resource areas. The 2010 corridor boundaries generally follow 2005 environmental corridor and isolated natural resource area boundaries and 2010 Wisconsin Wetland Inventory boundaries, with some adjustments to follow woodland boundaries where necessary. The 2010 environmental corridor features were digitized by the Commission's GIS Division and reviewed by the Environmental and Land Use Divisions.

5.  Entity_and_Attribute_Information:

Overview_Description:
Entity_and_Attribute_Overview:
This digital inventory consists of a set of digital map files in ESRI geodatabase format. Each personal geodatabase file covers one County in the seven-county Southeastern Wisconsin Region for a total of seven geodatabase files in the data set. Each geodatabase file contains feature classes for each U.S. Public Land Survey System survey township within the County, and also contains one feature class with all survey township polygons merged into a layer covering the entire County. The data set consists of environmental corridor polygon features fitted to large-scale cadastral mapping where necessary.

Environmental corridors are areas in the landscape containing especially high value natural, scenic, historic, scientific, and recreational features. 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 available in ESRI geodatabase and shapefile format. The files consist of graphic map features only and do not contain additional 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 (located on the Commission's regional land information website at: <http://maps.sewrpc.org/regionallandinfo/metadata/delineation_environmental_corridors.pdf>).

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.
