Which I've also heard is a "no-no"? Add a comment. Active Oldest Votes. Also, if you're using the same base station over and over again, and PFO can't download its hourly files, you can circumvent it by adding a custom base station to the list used in the Differential Correction utility, and you can specify there the exact naming convention used for the hourly files: Click the Help in the following window for details on how to set the naming convention the Base File Address Format :.

I also realize that if in fact I can correct them I will have to pull use multiple base files as the GPS points collected are over multiple dates.

If you have the ssf file that the points were in then you should be able to run them through the Pathfinder software for the correction. I've generally found that the differential correction by pathfinder was never more than a few inches.

So the data collector may have been off instead of the fact that the satellites broadcast was mis-interpreted. If anyone has seen different I'd be happy to know. To correct just the shapefiles or the points themselves I think you would need to know which satellites were broadcasting the positions and at exaclty what time.

And possibly how many points were collected for each shot and how they averaged. GPS Analyst will store the ssf files in a geodatabase. It uses the same differential correction engine as Trimble Pathfinder Office to find all the necessary base files and correct the data. It will then build your features and store them in the same database. The coolest part is that since it stores both the. I can't answer the first question whether it's possible to do differential correction after the GPS data is in a shapefile , but Trimble's Pathfinder Office does indeed have a differential correction utility, and it will take care of locating the base station nearest to your GPS points of course it helps if your points are all in the same general area , downloading the appropriate files from that base station's FTP site, unzipping them, and correcting your data.

Usually all you have to do is point it at the rover. SSF files and pick the base station the software can download an updated base station list when you run it , the software does the rest.

If you don't have Pathfinder Office, try calling your local Trimble sales rep, where I work we rent Trimbles when we need them and the sales guy was willing to give me a free copy of an older version of Pathfinder Office so I could run differential correction on the files.

It's not the most recent version by a long shot but all I really use it for is differential correction and export to shapefile or whatever format. Sign up to join this community.
