[GIS] .gdb folder to map use for Garmin gps

file-geodatabasegarmin

My government provides maps that I thought I could use on my Garmin eTrax 20.
They come as a .gdb folder with these files inside. This is a N50 map over a state(Norway) if that matters.

I tried using Basecamp from Garmin but it seems to only acceps .gdb as a file, not a folder.

Is there a way I can make this into something Basecamp or Garmin eTrax 20 accepts?

Edit:

BaseCamp accepts these formats. But eTrax might not accept them. I dont know.
Accepted file formats

Edit 2:

Error when opening .gdx file in BaseCamp:
Unknown Error

Edit 3:

Here's my procedure:

Choosing all layers

Then I select all layers.
Select all layers
And eksport the layersexporting layers

Here I tried GPX without that ended with an error in BaseCamp

Tried KML which did work in BaseCamp but I only got markup for houses.
Markup for houses

Edit 4:

I have learned until now that i do have what is called "ESRI File Geodatabase (FileGDB)". The goal is still to have this transfered over to the Garmin gps.

I gave @AndreJ answer below a shot, but failed.

I attempted to use gdal(ogr2ogr) to convert fgdb dataset to osm and garmin gdb. It started processing, but I got some errors with field names not supported and some errors when writing.

GDAL is basically able to convert between the both by the use of the GPSBABEL driver.

I tried that using this command: 

ogr2ogr -skipfailures -f "GPSBabel" GPSBabel:gdb:outMapGarmin Basisdata_05_Oppland_25832_N50Kartdata_FGDB.gdb

Zero size file created

I pasted the errors here: errors on pastebin

If you are interested in polygons, you might think of converting the data to .osm format and render a GARMIN map with mkgmap.

ogr2ogr -skipfailures -f GPSBabel GPSBabel:osm:outmap.osm Basisdata_05_Oppland_25832_N50Kartdata_FGDB.gdb

I pasted the errors here: errors on pastebin

I wonder if I'm doing it wrong or is there some other way?

Best Answer

You are mistaking two data formats that use the same extension:

  • ESRI FileGDB can be used by GDAL and QGIS
  • GARMIN GDB can be used in Base Camp and Garmin GPS devices

GDAL is basically able to convert between the both by the use of the GPSBABEL driver.

But the driver uses GPX as an intermediate format, so the restrictions of that format apply to the GPSBabel output as well. The main obstacles are the absent of polygon, multiline and multipoint geometry types, and the limited allowed field names. You can use QGIS to sanitize your data with polygon to line and multipart to single part conversion. The output should be in EPSG:4326.

If you are interested in polygons, you might think of converting the data to .osm format and render a Garmin .img map with mkgmap. In QGIS you can transform your data to shapefile, and load that into the JOSM editor to apply tags like building=yes or landuse=forest. Save it to a .osm file, AND DO NOT UPLOAD TO THE OSM SERVER on exit.

Some Garmin devices allow .kmz files with georeferenced images to be loaded. QGIS can create georeferenced .jpg images with Save as image. Make sure to work in EPSG:4326 as project CRS. https://plugins.qgis.org/plugins/GarminCustomMap/ , https://www.maptiler.com/blog/2009/10/garmin-custom-maps-kmz-from-geotiff-via.html and https://support.maptiler.com/i80-import-custom-maps-to-garmin-gps might be worth to explore as well.
