Extract Point Data Tool Attribute information extracted for all data points in active layer Clipped to current map extent Extracted to g-zipped, tab-delimited, text file (.gz extension) Data then used with software of choice

Extract Point Data Tool

Grid Totals Report Tool Grid emission totals for all emission species reported (regardless of which layer is visible or active) Clipped to current map extent or area of interest defined by Select by Rectangle tool Report includes totals for point, area, nonroad and onroad emission sources, plus a total for all sources, per species Bounding coordinates and total area selected (in km 2 ) included Report displayed in HTML format

Grid Totals Report Tool

Transmitter Coverage Tool Reports on all NWR transmitter footprints that intersect the line feature of interest, clipped to current map extent NWR transmitter Call Sign and length of each feature intersecting the highway provided Length and percent of highway not covered by transmitters also presented, plus these areas highlighted on map in yellow Line/polygon intersection query
