DIGITAL DATA CAPTURE IN THE FIELD: ON-THE-OUTCROP MAP CREATION
In response to technological advancements such as tablet computers and GIS software packages, a multi-year partnership between the University of Victoria and the British Columbia Geological Survey has investigated on-the-outcrop digital mapping techniques. Our current deployment utilizes inexpensive tablet computers with GIS software: Microsoft Surface Pro 2&3 with USB GPS and Manifold™. High resolution imagery, topographic data, and any other pertinent digital dataset can be displayed at infinite scaling and modified as required during the mapping season. A streamlined MS Access database form linked to Manifold is used to capture field data entered by hand writing or voice recognition and instantly send that data to the map. Freeform notes and field drawings are captured in OneNote. Both manual and automated Cloud-based synchronization expedites data sharing and limits the risk of data loss due to tablet malfunction, loss, or destruction. A custom case protects the tablet and GPS while providing ventilation for cooling. The result…complete maps can now be created on the fly and fast-tracked to publication, saving the mapping crew time and effort in compiling notes and digitizing data at the end of a long day in the field.
This talk will outline the materials and methods used by the SNAP crew and share with you our experiences using the software as well as a view to the future for digital data capture in this and other projects.
