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.

Process Step:

Process Description:
The Maine Office of GIS completed the conversion of all final data layers from NAD27 to NAD83 in July 1999. All the data layers were converted using the ArcInfo (version 7.2.1) NADCON conversion and the "project" command. All data was copied to double precision, projected to NAD83, and then copied back to single precision. It was decided to keep the NAD27 quad structure instead of generating new quad boundaries from NAD83 coordinates - all indexes (quads) were projected to NAD83 by using the same process previously described. All MEGIS data libraries in ArcInfo Librarian were repopulated using the NAD83 indexes and data.

Format Version Number: ARC Version 9.x
Format Specification: ArcView Shapefile Format
Format Information Content:
MEGIS has made all vector layers, in the Maine GIS Internet Data Catalog, available in ESRI's ArcView shapefile format. A shapefile is a simple non-topological format that stores the geometry and attribute information for a set of geographic features as a set of vector (point, line, polygon) coordinates. Shapefiles draw quickly and directly in ArcView, ArcGIS, ArcExplorer. Shapefiles are a compatible data type for many other types of GIS software. Three files are fundamental to each shapefile: .shp stores the feature geometry (shape and location information); .shx stores the index of the feature geometry; .dbf a dBASE (TM) file stores the attribute information for the features. Other index files may be created to help speed analysis and query: these file formats are .sbn .sbx .ain .aix .fbn and .fbx. In addition you may find projection .prj, and metadata .xml, files associated with shapefiles.
