Gulf of Maine Habitat Analysis - top 25%, 5 acre blocks

Data format: Shapefile

File or table name: top25_5acres

Coordinate system: Universal Transverse Mercator

Theme keywords: fish, wildlife, habitat, trust species

Abstract: This shapefile shows 5 acre blocks of the top 25% habitat of the Gulf of Maine Habitat Analysis GRIDs. Data from the top 25% freshwater, salt water, forested and grassland data were combined and then only contiguous blocks greater than 5 acres were included in this shapefile. While deleting some smaller blocks of habitat, this shapefile creates a cleaner appearance to the data.

FGDC and ESRI Metadata:

Metadata elements shown with blue text are defined in the Federal Geographic Data Committee's (FGDC) Content Standard for Digital Geospatial Metadata (CSDGM). Elements shown with green text are defined in the ESRI Profile of the CSDGM. Elements shown with a green asterisk (*) will be automatically updated by ArcCatalog. ArcCatalog adds hints indicating which FGDC elements are mandatory; these are shown with gray text.

Data Quality Information:


Lineage:
Process step:
Process description:
In ArcMap 8.3; started with gomtopqrtr91, created GRID value1 that gives all 1,2,3,4 cells a value of 1. Then created regions of contiguous non-zero cells (probably could have done this without the value1 GRID):
regiongroup (value1,#,eight,cross,0)
saved as cregiongrp

Then in ArcView, created GRID of regions with >22 cells (> 5acres):
([Cregiongrp . Count]) > 22
saved as cregiongrp2

ArcMap; pulled data out of gomtopqrtr9:
con([cregiongrp2] == 1,[gomtopqrter91])

Process software and version: ArcMap 8.3, ArcView 3.2
Process date: 18 September 2003
