Unfortunately I haven't found an Open Source solution. However, there is a Trimble extension in ArcMap called GPS Analyst that will post-process .ssf files. They have also released a new version for ArcGIS 10.1 called Trimble Positions desktop addin that is the current ESRI solution.

First, welcome to the site! To check your data back in you need to run Check-In (form the Data Manager Toolbar) for each of the AXF files. This will check modifications (edit, create & delete) back into the parent Geodatabase. Note that if there are any conflicts, last in wins (ie, new data will overwrite existing data even if that data had changed ...

I'm pretty sure there isn't a good way to get from SSF to a shapefile without Pathfinder Office. Trimble has done a pretty good job of locking that format down. It might be faster to open up your data in terrasync and just copy down the coordinates. It would be tedious (although you mention that your data set is fairly small), but then you could punch the ...

You can export *.ssf file from Trimble Pathfinder office to shape files and display in ArcMap. If you have any query or you want to convert your *.ssf file you can contact me.

A nice cost effective intuitive application called GPSMeter will allow you to 'average a position http://www.gpsmeter.com/index.php Good support too from the developer

The Nomad comes with SatViewer which allows you to record up to 64,000 characters of NMEA data per file - NMEA has many different messages defined but all are text, easy to parse, and the GLL message contains lat/long/time etc. http://www.trimble.com/outdoorrugged/nomad/SatViewerManualrevA.pdf http://www.gpsinformation.org/dale/nmea.htm

We (embarrassingly) purchased at GeoXT without software and were put in a position to attempt to obtain GPS data and post-process it. In my research I stumbled on this http://gpspp.sakura.ne.jp/rtklib/rtklib.htm and believe it may be a good lead - our office has not had much flexibility to look into the potential. "RTKLIB is an open source program package ...

The ssf format is specific to Trimble, representing data directly off the GPS unit, and it is not a GIS format. The workflow in Pathfinder is to differentially correct this file and then export it into a desired format. From within Pathfinder there is a Menu option to export the corrected data to a shapefile. As previously pointed out an alternative is the ...

SSF is an acronym for Trimble's proprietary "Standard Storage Format" file. Trimble Standard Storage Format (SSF) [...] describe coordinate geometry [...] information from Trimble TerraSync™ field software and GPS Pathfinder Office software. Referenced from May 5, 2010 Trimble press release.

Please use the 'set custom view settings' in eCognition 8.9 to set/control the zoom via a rule set.

Trimble makes a dedicated software package for this (other than Trimble GPS Analyst), Pathfinder Office, which will let you do this and lots of other things with your Trimble files. Contact your Trimble rep (if you bought the unit from them) and they may be able to hook you up with a free or discounted copy. You can export positions that aren't part of a ...

It's easy to confuse positions and actual points which are different things. Positions are logged to a single point, which are then averaged to produce the final location of a point. If you recorded a bunch of positions that followed a fenceline into a single point you'll probably have some trouble getting those into the format you wanted. This is done ...

With the Trimble GPS Analyst Extension for Esri ArcGIS for Desktop Software you should be able to connect your Trimble Supported formats Base file formats Hatanaka (Compressed RINEX) RINEX Trimble DAT format Trimble SSF format http://www.trimble.com/mappingGIS/gpsanalyst.aspx?dtID=applications&

The code looks like the USNG or MGRS coordinate system, see https://en.wikipedia.org/wiki/United_States_National_Grid and https://en.wikipedia.org/wiki/Military_grid_reference_system for further details. 12RVU indicates that you are in UTM zone 12, somehwere in Western Mexico. You might need to read the manual on how to change the setting (I don't have the ...

You don't actually need the full Pathfinder Office suite to get your data off the handheld and onto a PC, all you need is the Trimble Data Transfer Utility. It's a free download. The same utility is included in the full Pathfinder Office suite, but Trimble makes the data transfer utility freely available since (as you know) the people using GPS in the field, ...

The easiest and most straigh-forward method is to use Pathfinder Office. Load the images into Pathfinder Office as backgrounds, be sure to provide projection information. Once they are in Pathfinder Office you can use the Data Transfer Utility to send them to the device. TIFFs are supported in TerraSync, but I have had issues with some of them not wanting ...

If you download Pathfinder you can install it without a key and use it just to transfer the data off the device. All the other tools are disabled but you can at least get the data you need. If that's not an option you can pull the files manually but you'll need Pathfinder eventually to recombine them into SSF files that you can export/use elsewhere. When ...

Did you edit the data in that table at all? It's strange how there is one row with its lat/longs in DDMMSS when all the others (the ones that aren't blank) are in decimal degrees. Also, do the points which are missing positional data actually show up in ArcMap? Are they where they're supposed to be? As far as the missing data, it looks like everything went ...

I would take a step back and ask is my GPS capable of making a DEM. The answer to this question for most consumer grade units is unfortunately no, well not without quite some work before you start interpolating etc. The vertical error in GPS can be very large even with modern units. What you are measuring is also an issue, see below. "A brief examination ...

starting from points to build a continuous surface is called spatial interpolation. You can find information about those methods on the Web. Surfaces can be represented using wo different models : raster or TIN. Most existing DEMs use the raster model, but TIN is sometimes a good alternative. As its names says, TIN are composed of irregular triangles, ...

Use Trimble's GPS Pathfinder Office software "Export" feature to transform the SSF to a shapefile (shp).

Something to consider Are your pick lists static, i.e. you do not need the ability to add to a list as you survey? If you need that capability then you you need to create a table behind the scenes that populate the combobox. With an exhaustive list of 7,800 species this would be impractical to implement but you could come up with a set of comboboxes that ...

I am not in a position to provide you the exact workflow but it must be possible. I believe you would have access to Trimble Business Center (TBC) application which is provided along with Trimble GNSS receivers. Once you post-process your data you would be able to export it into commonly used GIS formats like shapefiles. This exported data can be used ...

I cannot answer but this other question may give you some useful material. RTKLIB is the reference open source post-processing solution, but it doesn't seem to support .ssf (yet?).

Trimble ssf files and ddf files. You can use "GPS Pathfinder Office" program to convert filetypes and projections. It has it own problems, attleast version that i have dosen't handle scandinavian characters right, and when exporting to shapefile it uses max 10 chars in column name. So you need to rewrite feature names again if those are longer that 10 char. ...

It has been a while since I worked with a trimble dictionary. It should be too difficult to parse out the portions you need. I would start with a small export from trimble to a text file and compare that to your htm (hwhich is just a glorified text file). I do remember that the dictionary editor has some options for input and output.

Exporting offsets would allow the GIS user to see that the accuracy is not what appears in the HPREC and VPREC fields. Offsets are sometimes way off and there is no way to know an offset was applied if it's not exported. I have to resort to putting an Offset = y/n field in the data dictionary of each feature type to capture this.
