I hate to be discouraging, but I doubt that you will get any responses about this here. That is a very expensive professional surveyor's GPS and this site is for recreational devices from Garmin.
General Discussion / for gps leica 500

Hello forum members,

I am in need of a tutorial or guide on the operation of the Leica GPS 500. If anyone has any experience with this device and is willing to share their knowledge, it would be greatly appreciated. Thank you in advance for your help.

Best regards,

Hi Everyone,

Hopefully I post this in the right section, I have done a few searches on the Forum without any luck.

I ride an Indian Chief Dark Horse 2022 which basically comes with a 4 inch round TFT display that integrates a GPS unit, maps, navigation and POI's or at least is supposed to because I live in Bahrain and Indian (owned by Polaris) does not release maps for Bahrain (or Saudi Arabia for that matter), their concept of the Middle East is limited to Israel and United Arab Emirates.

Long story short, the GPS interface looks an awful lot like a Google Maps interface (see picture)

You cannot view this attachment.

and the map update that is proposed by Indian/Polaris on their website for the Middle East (again, limited to Israel and UAE) is an 8+ GB .mapdata file, an extension for which I find very little information on the web.

I'd like to understand what this ".mapdata" is, how it's actually generated and what I could do to obtain one for the countries I'm actually interested in (Bahrain & Saudi Arabia). The fact that the GPS unit seems to run a version of Google Maps should definitely make that easier but my knowledge is failing me.

I can post the ".mapdata" file somewhere in case it's of use to anyone, it seems like a proprietary extension to Indian/Polaris however I have a hard time believing that the content of the package is anything proprietary.

Thanks for any help you can bring,

Those other maps were deleted and redirect to your new one.

I've been away for the holidays. Now that I'm back, I tried Sockmonkey's procedure. I am happy to report that it worked perfectly.

Thanks to everyone for your help. And thanks for the maps too.

This is a *volunteer* project and part of my way to 'pay it forward'.

If you have a JPG that you have managed to georeference then you can use the free software KMZFactory to split the JPG into tiles which can then be used as a Garmin custom map.  This post describes a way that you can make JPGs that are automatically georeferenced.

GISsurfer ( is a general purpose web map I developed.  It can be used for any non-commercial purpose.  Various basemaps are built-in including scans of the paper USGS topo maps.  GISsurfer has broad support for displaying basemaps and overlays that are hosted on GIS servers.

When GISsurfer is in screenshot mode (Menu > Screenshot mode) then all controls are removed from the map so the user can:
●   Take a screenshot that is 100% map
●   Shift the screen *exactly* one screen worth up/down/left/right
●   Take a screenshot that is 100% map
●   Shift the screen *exactly* one screen worth up/down/left/right
●   Repeat as much as you like

While the user is taking screenshots GISsurfer is keeping track of all the georeference data.  And since the screenshots exactly adjoin they are easy to stitch together into a larger image.

I routinely make georeferenced JPGs that cover 300+ square miles and are 25-30 screenshots stitched together.

The GISsurfer homepage is at
For the detailed documentation go to the 'Help' page and see the list of PDF files.
One of those PDFs will walk you through the process of making georeferenced screenshots.

Finally, to help you find GIS data that you would like to include in a Garmin custom map, I curate a list with addresses for 3,000+ ArcGIS servers at all levels of government from federal to local.  An updated list is usually posted each Wednesday and any bad links are either fixed or flagged.

If you want to save space on your system disk, it is sufficient to copy a Shortcut to the GMAP folder instead of the folder itself.

Sometimes (for me, at least) Basecamp does not see the map in Program Data but does see it in C:\Program Files (x86)\Garmin\BaseCamp\Maps\
General Discussion / Australia and South East Asia
Last post by sockmonkey - November 22, 2022, 07:59:23 AM
I've recently uploaded a new map and updated an older map.

Initially I was going to include Indonesia as part of the South East Asia Topo, but the map would anticipated to be to big to upload as a single map, and I'm trying to avoid the multi part map.  At some point in the future I will likely create a topo map for Indonesia.

About a year ago I created and uploaded the Topo Map of Australia, but I had to do it in two parts because is was too large as a single map to upload (over 2 GB)  I recently was working on an update and found the the large size of the original was due to a "typo".  This typo is related to the DEM (3d and shading).  I caught it on some other maps but not this one.  If some input values for the DEM are off it creates an unnecessarily large map.  I've corrected this and the map is more in line to what I'd expect it to be.  I used current OSM data and the map is named AU-AustraliaTopo, the previous maps were part 1 and 2.  I have requested deletion of those and would direct those interested in this map to
