<DIV STYLE="text-align:Left;"><DIV><DIV><P><SPAN>METWP24PD </SPAN><SPAN STYLE="font-size:12pt">depicts dissolved political boundaries for all Organized Towns and Unorganized Territories in Maine at 1:24,000 scale. "Dissolved" means that municipalities or townships with multiple disconnected entities (ex. islands) are grouped as multipart polygons in a single geometry with the appropriate municipality or township label and attribute data. This approach reduces the number of labels required and improves layer drawing performance for low-bandwidth environments. Example: a town has 430 distinct island entities that are all labeled as "town" in addition to the municipality itself. When dissolved, it has only one geometry that includes all 430 entities' combined area and attributes with the municipality, and one label of "town".</SPAN><SPAN /><SPAN STYLE="font-size:12pt"> METWP24PD includes common town names and authoritative geocodes in its attribute information. The layer was created using the USGS 7.5-minute map series and the Maine GIS base layer COAST, which contains Maine's coastal Mean High Water (MHW) mark and Maine islands. To correct mapping errors and reflect changes to Minor Civil Division (MCD) boundaries, arcs and polygons were added or updated using the following data sources: photorevised USGS data; Maine GIS base layer coincident features; legal descriptions; GPS data; and Maine Department of Transportation (MEDOT) engineering plans. METWP24P also contains USGS 1:100,000-scale data and U.S. Department of Commerce Census Bureau TIGER Line Files from 1990 and 2000 where these provide a more correct or best available representation of a feature in question.</SPAN></P></DIV></DIV></DIV> |
