[Gvsig_english] transfer GPS-data, “gpx”-format, to gvSIG

[Klaus Schaefer]

Dear gvSIG-friends,

many of you work with GPS devices to map network and customer data for water
scheme documentation (cadastre), project layout, design and other planning
activities. Many of you, as well, use a GIS application to visualize and
analyze the respective data and/or combine it with customer data, district
data, billing data and other sources of data.

Different GPS-devices work with different interfaces to transfer data to a
GIS. Many of you work with Garmin GPS devices, mostly of Dakota and Oregon
types. I have now compiled a small workflow and process description on how
to get GPS data into a GIS using the raw “gpx” files that are provided by
these devices. Other GPS devices, like “Garmin eTrex”, “Trimble” or
“Magellan”, may not produce “gpx” data files and need other processes in
combination with GIS. However, the Garmin “Dakota” and “Oregon” types seem
to be the most popular ones and other types and brands may use the
“gpx”-interchange format as well.

Different GIS applications (ArcGIS, QGIS, gvSIG…) have different ways of
dealing with GPS-data as well. Some can import from GPS devices directly,
but probably not from all of them. Most common standards to provide data for
GIS layers are shape files or spacial database tables (e.g.
PostgreSQL/PostGIS).

Since many people working with GIS/GPS applications have similar tasks to do
and have to deal with similar issues and requirements, several tools have
already been developed and provided to the community. Over the last two
years me myself I have done a lot of work in these kind of scenarios and I
realized that it is time to compile a “best practice” handout from my
experiences so far, for the benefit of all of you. Of course there is not
“one way only” to achieve the same results. However, I wish this small
document to support you in your daily efforts.

Should you have any questions, please don’t hesitate to get back to me. I
appreciate any feedback from your side, so hopefully these instructions can
be extended with your experiences, too. Please feel free to distribute this
document to other persons that may be interested.

Thanks a lot and best regards
Klaus
