Title: Maine Biophysical Regions
Geospatial Data Presentation Form: vector digital data
Description:
Abstract: BIOPHY depicts boundaries of 15 Biophysical Regions in Maine at 1:250,000 scale. The regions were developed in a statewide classification (McMahon, 1990) by Janet McMahon who examined spatial patterns in a number of mapped environmental variables. These patterns were statistically evaluated using canonical correspondence analysis. Ordinations of 1,966 samples, 95 woody taxa, and 22 environmental variables, reveal that both biophysical regions and woody species vary primarily along a climatic gradient of increasing annual temperature, potential evapotransportation, heat sum, and other factors associated with temperature. Boundaries were mapped for 'Biophysical Regions of Maine' at 1:700000 scale by Maine State Planning Office (MESPO) staff in 1990. Maine Office of Geographic Information Systems (MEGIS) staff digitized these boundaries from the 1990 publication, recompiling the data onto a 1:250,000 scale base. The state boundary and coastline were extracted from the coverage METWP250. Each region contains attribute fields extracted from a summary table on the 1990 publication. The coverage was renamed from BIOPHY250 to BIOPHY in 2001.
Purpose: Statistical analysis for regional study of patterns in landscape and vegetation.

Use Constraints: Users must assume responsibility in determining the usability of this data for their purposes. Digital maps retain the accuracy of their source materials. The best use of data mapped at scales of 1:500,000 and 1:250,000 is in statewide planning and studies; at 1:100,000 in regional planning and studies; at 1:62,500 and 1:24,000 in detailed studies and local planning; and at 1:12,000 and 1:5,000 or larger scales in parcel level studies and detailed local planning. In the use of Maine GIS data, please check sources, scale, accuracy, currentness and other available information. Please confirm that you are using the correct copy of both data and metadata from the Maine GIS Data Catalog. Updates, corrections, and feedback, incorporated in the Maine GIS database are made in accordance with "Data Standards for Maine Geographic Information Systems", 2002, and coordinated by MEGIS.
