Description:
Abstract:
This Undeveloped Habitat Blocks dataset represents areas in Maine that are at least 500 feet away from development and improved roads. It was developed to highlight areas in Maine where development has not yet occurred. The polygons are based on 3 existing datasets: 1:24000 Roads data provided by The Maine Office of GIS, additional 1:24000 Public Roads data from The Maine Department of Transportation (updated 2002), and Land Use / Land Cover data developed by the Maine Gap Analysis Program, USGS Biological Resources Division.
Purpose:
The undeveloped habitat blocks dataset is part of a group of datasets developed as part of the Beginning with Habitat Outreach project, a cooperative effort of The Maine Natural Areas Program, Maine Department of Inland Fisheries and Wildlife, and other government and non-profit agencies in Maine. Maps produced from this data are presented to municipalities and land trusts to encourage open-space planning efforts that include a vision for the preservation of biodiversity.

These data are for planning purposes only and should not be used as a statutory representation of the resource.

Supplemental_Information:
This dataset is only as accurate and up-to-date as the source data that it is based on. Before detailed planning efforts are conducted with this dataset, local knowledge of road classification and recent development should be incorporated

Process_Step:
Process_Description:
1) SHAPEARC public_roads_2002.shp (DOT's data) to a line coverage 2) RESELECT roads with SURFACE_TY = "flexible," "high flexible," "high rigid," or "port cement comp" to get all improved public roads. 3) SHAPEARC roads dataset from MEGIS (based on USGS data) to a line coverage (includes public and private, but dataset is from 1980s 4) RESELECT roads with CLASS <= 4 (improved roads) 5) APPEND DOT and USGS line coverages 6) BUFFER appended line coverage to 500 ft 7) RECLASSIFY Maine GAP (1993) data to isolate developed areas (32=residential, 33=dense residential, 34=urban/industrial, 35=highway/runway) 8) Use EUCDISTANCE grid function to create a floating-point grid of distances from developed areas 9) use CONTOUR grid function to create arcs 500 ft from developed areas 10) BUILD arcs to polygons 11) ADDITEM g-inside to polygon attribute table 12) SUMMARIZE ZONES for contour polygons, using polygon id as the field to to define zones 13) JOIN zone summary table to polygon attribute table for contour polygons on the polygon id field 14) SELECT all records with [count] 
 0 15) CALCULATE g-inside = 100 for those records 16)
UNION buffered, appended roads from DOT and USGS to the contour polygons created from the GAP data 17) ADDITEM dev to the unioned coverage 18) SELECT records where inside=100 (inside buffers for appended roads) or g-inside = 100 (inside 500 ft contour for developed areas) 19) CALCULATE dev = 'Y' 20) DISSOLVE unioned coverage on dev 21) IDENTITY dissolved coverage to state of Maine outline 22) ADDITEM dev-code to resulting coverage (stateblocks) 23) SELECT records where dev = 'Y' 24) CACLUATE dev-code = 1 25) In GRID, SETWINDOW to GAP grid 26) Use POLYGRID function to create a grid from the stateblocks polygon coverage based on dev-code 27) RECLASSIFY stateblocks grid to create a binary mask with 0 = 1, 1 = NoData, and NoData = 1 28) In GRID, SETMASK to this reclassified grid 29) RECLASSIFY the GAP grid to set water, saltwater, and developed areas to NoData and all undeveloped land areas (codes 1-30, 32-37)to 1. 30) ADDFIELDS "landarea," "landacres," and "acrestext" to stateblocks polygon coverage 31) SELECT records from stateblocks where dev = '' (undeveloped blocks) 32) SUMMARIZE ZONES for stateblocks polygon coverage with the polygon id as the zone identifier and the undeveloped lands grid created in step 29 as the variable to summarize 33) JOIN zone summary table to stateblocks polygon attribute table on the polygon id field 34) CALCULATE landarea = count * 900 35) CALCULATE landacres = landarea * 0.0002471 36) Create text strings in acrestext to append " acres" to the landacres value for all records with landacres > 100.
