Identification_Information: Citation: Citation_Information: Originator: MEDEP-BLWQ-DEA-Biomonitoring Title: dea_bio_stations Geospatial_Data_Presentation_Form: vector digital data Online_Linkage: \\depsuna\workspace\lawb\dea\biomon\shapefiles\dea_bio_stations.shp Description: Abstract: This shapefile contains the locations of biological monitoring activities in rivers and streams across the State of Maine. Data collected at each site may include macroinvertebrates, algae and water chemistry. This data set was initiated in 1983. Point locations were either obtained with a Garmin handheld unit or hand digitized from USGS Topograpgic maps or aerial photos. Purpose: To geographically locate and map river and stream sampling stations.

Completeness_Report: The data set is complete as of the Fall of 2004. It is updated at the end of each year's sampling season. Positional_Accuracy: Horizontal_Positional_Accuracy: Horizontal_Positional_Accuracy_Report: The horizontal accuracy of the data points is mixed and there is no distinction made within the table. The horizontal accuracy is 15 meters for site locations recorded with a Garmin hand held unit and between 3 - 20 meters for the site locations that were hand digitized. Vertical_Positional_Accuracy: Vertical_Positional_Accuracy_Report: No vertical accuracy is recorded Lineage: Process_Step: Process_Description: This table is a collection of data points began in 1983. Initially the points were selected off DeLorme maps, aerial photos and/or USGS topographic maps and the latitude/longitude were estimated. Beginning in 2002 the points were collected with a Garmin handheld GPS unit.
