GIS & Mapping
Map Products and Services to Assist NABat Activities
The SE Bat Hub can provide GIS-based mapping assistance to new and existing NABat projects. We can help you find official NABat layers, habitat information, road locations and classifications, or other data for planning NABat surveys, or analyzing effects of geographic features on bats. We have provided some GIS data below, but feel free to contact us if you need other data or assistance with mapping services.
Geographic data layers to assist NABat related activities
5 km GRTS quadrant inter-cardinal ID
This ArcGIS shapefile is a polygon layer of the 5 km quadrants of NABat GRTS cells within the southeast region. We added a field, Quad_ID, indicating the inter-cardinal direction (NW, NE, SW, or SE) of each quad. You can use this layer to get the quad ID of survey locations with the Spatial Join tool. This can be very useful for checking site locations, or to automatically generate NABat-centric site names for sensitive survey locations, for instance.
Offshore CONUS 10 km GRTS joined with Onshore
This ArcGIS shapefile is a polygon layer of the offshore 10 km continental US (CONUS) NABat GRTS cells which shows onshore cell IDs where they overlap. Along the shoreline, many cells from the onshore CONUS grid overlap with offshore cells. Surveys within the onshore grid may already be occurring within the offshore frame. The offshore and onshore frames do not share CONUS_10KM IDs or GRTS_IDs. We added fields to show the onshore CONUS_10KM IDs and GRTS_IDs (ON_C10KM and ON_GRTSID, respectively) where these grid cells overlap.
