Olga Stewart Delivers Presentations at Two Alaska Conferences

Olga Stewart (Alaska) presented at the Alaska Forum on the Environment 2017, at the Dena'ina Center in Achorage, Alsaka on February 8, 2017 and at the 51st Alaska Survey and Mapping Conference at the Hilton Anchorage Hotel in Anchorage, Alaska on February 16, 2017.

The presentation at the Alaska Forum on the Environment 2017 was entitled "Creating and Utilizing Spatial Data in Remedial Investigations: From Archives to Desktops to Mobile Devices," and was delivered with two co-presenters from other firms. This presentation focused on digitizing historical as-built drawings, ortho-rectifying and georeferencing historical aerial imagery, and utilizing those historical data in the field on mobile devices to successfully conduct a remedial investigation.

The presentation at the 51st Alaska Survey and Mapping Conference was entitled "Real-Time Use of Mobile-App Collected GPS Locations for a Remedial Investigation." It focused on how and why GPS data were collected in the field. Over 2,700 locations were surveyed using both an EOS Arrow 100 GPS Bluetooth-connected to a custom iPad app and a traditional RTK GPS; the two datasets were compared and the accuracy of the EOS Arrow 100 GPS was presented. Both presentations were related to a U.S. Army Corps of Engineers-Alaska District Formerly Used Defense Sites (FUDS) project with Ahtna Engineering as our client. Dan Pankani developed the mobile app and Andrew Higgins developed a desktop app to support field data collection and RI data management.
