GIS and GPS / Re: GPS with ArcView

Ah, yes, Mapsource!  I forgot about that!  :P

I guess the reply to MadzlanH is that Garmin is probably a good choice, as long as he uses the GPSMap series (76csx or 60 csx), the Vista eTrex series, or the newer (and more expensive) Colorado and Oregon series.

GIS and GPS / Re: Garmin GPS to Arcview/Arcmap/GoogleEarth Utility

Ah, that's great!  I was worried that the default projections in the software are predominantly US-oriented, but I guess if you import them without projections, they default to geographic coordinates using WGS84 datum.

GIS and GPS / Garmin GPS to Arcview/Arcmap/GoogleEarth Utility

I came across this web page today, and thought you might be interested in this utility  ("DNRGarmin GPS Application")being offered free by the Minnesota (US) Department of Natural Resources.

This extension was built to provide users the ability to directly transfer data between Garmin GPS handheld receivers and various GIS software packages. Using this program a user can use point features (graphics or shapefile) and upload them to the GPS as Waypoints. Line and Polygon Graphics or shapes can be uploaded to the GPS as Track Logs or Routes. Conversely, Waypoints, Track Logs, and Routes collected using the GPS can be transferred directly to ArcView/ArcMap/Google Earth/Landview and saved as Graphics or Shapefiles.  This program has a real-time tracking mode that allows users to follow their progress on the ground within an ArcView View Document, ArcMap Data Frame, or Landview Map. This real-time track log can be saved as either points or lines as a set of graphics or in a shapefile.

I haven't tried it yet, but if it offers seamless transfer to tracks and POIs from Garmin GPS units to ArcView, it may be worth trying out!

In my Garmin eTred Vista HCx, the "Datums" field in the setup has "Kertau 1948" as an alternative datum to the standard WGS84.  I don't know if taking GPS readings using the the Kertau datum will help in transferring the X-Y points as an event layer to your RSO projection/coordinate system.  But at least the Garmins have the "Kertau" option in the Datums setting.  I hope this helps.
