How to Link Documents to EIM Studies
Link to electronic publications and documents in Ecology document management systems. Naming Conventions for EIM Studies

Locations

Convert Local Elevation Datums to NAVD88
If you surveyed your wellhead elevations to a local (e.g. 100 ft) datum, convert to our standard datum Get Lat/Long and Elevation from EIM map
Coordinates and elevations for your field locations Get NHD info from EIM map
National Hydrography Dataset stream reach and measure Horizontal Coordinate Accuracy
Includes information on GPS units How to Name and Describe Field Locations
Temporary Environmental Investigation Wells
Well metadata for Direct Push/Geoprobe EIWs
