Step to post process GPS Data

After the field data collection, you will need to transfer data from the GPS to a PC and perform post-processing. All collected GPS data needs some form of post-processing whether it is differential correction and/or editing. After transfering, view your data on the PC for verification. While your data file is onscreen, you can identify any unwanted positions and/or features as well as attribute information and perform preliminary editing. Depending on your GPS unit and data collection software, this step may or may not include converting the data to a GIS format at the time of downloaded. Either way, it is important to have clear procedures for post-field data management and verification.
