ABSTRACT
You have been given, or you have collected, files with the extensions SSF (Standard Storage Format) or COR (for differentially CORrected) files. These files have been processed and displayed using the Trimble Pathfinder Office software. Your goal now is to use these data files in a Geographic Information System (GIS) where they can be considered with many other data sources that you may have available. This is not a difficult process but you really must be careful: it is quite easy to get what looks like a reasonable GIS file, but one that has the locations wrong, thus making the activity worse than useless.
