Garmin GPS: Create a custom map with MapTiler

To create a custom map was never so simple. MapTiler converts your map into the high resolution format compatible with Garmin handheld GPS devices.

You can very quickly import any map in only 3 steps:

1) Use MapTiler to create a map from any image
2) Pack the result into .zip archive and rename to .kmz
3) Upload the map into your Garmin handheld device

Why not use Google Earth overlay?
Compared to the traditional way recommended by Garmin, this approach has several advantages:
  • you can import larger maps
  • the georeference is much more precise, mainly on large areas
  • the process is faster

Just follow the tutorial at

GDAL in Docker - install & run with a single command

Have you been struggling with complicated installation of open-source GIS command-line tools with all the drivers on your computer? Now it is much easier!

One command to run any GDAL tool in the terminal on any platform with Docker:

docker run -ti --rm -v $(pwd):/data klokantech/gdal /bin/bash

or run a GDAL utility of your choice directly (in this case gdalinfo):

docker run -ti --rm -v $(pwd):/data klokantech/gdal gdalinfo yourfile.tif

The current working directory is mapped to the docker container and is writeable. All relative paths and local bash autocomplete is therefore usable.

The container is minimal (about 350 MB) and is compiled from the latest stable GDAL with MrSID, ECW and JP2KAK drivers.

It has been made to simplify deployment of MapTiler Pro to all Klokan Technologies GmbH customers who can now easily use the MapTiler software with docker in a similar way.

This is an alternative to .rpm and .deb packages which are available for various Linux distributions, next to the installers for Mac OS X and Windows.

Deployment with Docker is extremely easy on any platform - from computing clouds such as Google Compute Engine or Amazon EC2 to any developer's laptop.

Tileserver: an open-source tool to publish maps online

If you need to publish your maps online, there is no need for Geoserver, Map Server or ArcGIS Server, which are all hard to install and maintain.

Tileserver, an open-source alternative from Klokan Technologies, is really easy to use with any standard hosting that supports PHP. Just upload the maps you created with Maptiler, and you immediately get dozens of popular web viewers with interactivity, including Google Maps API, Leaflet, Open Layers, WebGLEarth and Mapbox JS. The source codes are ready to copy and paste into your website.

All the maps that you upload can also be directly opened in GIS software such as Quantum GIS, ArcGIS or uDig. The hosting viewer comes with step-by-step tutorials on how to do that.
