December 13: GIS Coffee Hour

On Tuesday, December 13 from 10:00 a.m. to 11:30 p.m. in Pearson Hall room 304 Lillian Wang from the Delaware Geological Survey will present “Geologic Field Mapping in Delaware–Paper Maps to ESRI Collector App” for the UD GIS Coffee Hour.

For many years, Delaware Geological Survey (DGS) geologists used paper maps and aerial photography to plan field work and navigate in the field.  The ESRI Collector App has enabled geologists to navigate in the field with up-to-date data layers and create and edit GIS data on a mobile device.  This work flow saves time before, during, and after working out in the field.  This presentation will step through how to create maps to use in the Collector App and download data created in the field back to desktop.

If you are unable to attend in person please contact Olena Smith ( to join via telephone or video conferencing.
