USING GPScorrectThis section outlines the workflow for configuring your equipment and software, collecting datausing the GPScorrect extension, and processing the collected data. It provides step-by-stepinstructions for key tasks. For detailed information on other tasks, refer to the documentation forthe product used to perform the task.
• Preparing for data collection
Before you collect any data, configure ArcPad to use the GPScorrect protocol. Then useGPScorrect to configure GPS settings, select real-time correction sources if required, and enableGPS logging to SSF.
• Data collection
Once you are in the field, use GPScorrect to check GPS and real-time status. Use the Plansection in GPScorrect to plan your data collection session around the times of best satellitegeometry, and adjust your GPS settings if necessary. Then use ArcPad to collect data as usual.
• Processing the data
Back in the office, transfer the Shapefiles and their matching SSF files to your office computer.Then use either GPS Pathfinder Express or GPS Pathfinder Office to differentially correct theSSF files and merge the GPS data from each SSF file into the corresponding Shapefile.

In ArcPad, each feature type is stored in aShapefile. When you create a layer or add featuresto an existing layer, GPScorrect automaticallycreates an SSF file with the same filename andstores all GPS position information for that featuretype in the corresponding SSF file.
