Working with GPS Data in the Field?
Are you looking to start a data collection project in the field with GPS units? We have a variety of equipment available on campus to checkout for GPS projects:
- TDC600 Android GPS unit
- R2 Receiver (sub-decimeter accuracy)
- ArcGIS Field Maps + ArcGIS Online for data collection
**ArcGIS Collector has been deprecated in most forms and was replaced with Field Maps. We no longer support ArcGIS Collector at St. Olaf**
Data collected in this way does not use post-processing. If your project needs post-processing, please fill out this form to request alternative equipment.
- Create a Feature Layer in ArcGIS OnlineCreate a layer for data collection in ArcGIS Online and make it available for editing
- Collaboration in ArcGIS OnlineWorking with a group? Make sure to request an ArcGIS Online Group and share your feature layer/data collection layer to the group so multiple people can contribute.
