Download the GLOBE elevation tiles from here:  https://www.ngdc.noaa.gov/mgg/topo/gltiles.html Unzip the file Rename the file to *.data Start GIMP and open the file. This dialogue will appear:  Now use the Colors->Levels Tool to make the data more useable:

I've created a isometric like image of the Isle of Mull in Scotland with GIMP, G'mic and Inkscape for a photo book: I used Gimp 2.9.9 with the new HGT file import and the height maps from the NASA. You can read more about it here: https://dablogter.blogspot.de/2018/01/gimp-now-supports-hgt-file-format.html G'mics 3D elevation plugin: Water texture from here: https://www.roblox.com/library/31952856/Water-Texture-FREE The land colours are from a blurred screenshot from Google Earth. Inkscape for the markers: The sun is the standard "Sparks" brush from GIMP. Cloud and bird brushes from https://www.deviantart.com https://para-vine.deviantart.com/art/Cloud-Brushes-152820554 https://wingsofahero.deviantart.com/art/Bird-Brushes-119021426 https://wingsofahero.deviantart.com/art/Flying-Bird-Brushes-116541763 And a lot of fine tuning in GIMP, here is a screenshot of the layers dialogue:  

In the latest developer version Gimp (2.9.8) now supports the HGT file format. So what is HGT? That’s topography data basically just containing elevation in meters of various landscape ( HGT stands for “ height “), gathered by the Shuttle Radar Topography Mission (SRTM) run by various space agencies (NASA, National Geospatial-Intelligence Agency, German and Italian space agencies…).  You can read more about the file format in Jehans blog: https://girinstud.io/news/2017/12/new-format-in-gimp-hgt/ Get Gimp >= 2.9.8. Get the HGT file you are interested in. I used this on: https://dds.cr.usgs.gov/srtm/version2_1/SRTM3/Eurasia/N50E014.hgt.zip Unzip the file. Open the HGT file in Gimp.  It is OK, that the file is all gray. Now we have to go to the next step. Edit the HGT file with Colours -> Levels Use the black and white triangles in the "Input Levels" section to show only the interesting data. To be more exact you can open the levels dialogue a second t...

Last year I blogged about the KML and the geoJSON export scripts for darktable . I've wrote an other script for darktable, the geo toolbox and it looks like this: I'd like to describe the functionality here short: Button 1 and 2: With this two buttons you can select all images with or without location information in the Exif tag. Button 3 and 4: With this button you can copy GPS information from one iomage to an other. With the checkboxes you can select which part of the GPS information you like to copy. Button 5 [open in Gnome Maps]: This button opens Gnome Maps and shows the position of the photo in the map. Button 6 [reverse geocode]: This function is still not very useful. It uses a web-service from Mapbox to get information from OpenStreetMap about the place of the selected photo and shows this in an info window. Button 7 [export altitude CSV file]: This function exports a CSV file from the selected images with the altitude in meters i...

Last week Google release a new version of Google Earth. Google made a complete rewrite from a classical client to a web client. Really new and nice are only the interactive guided tours. This new client has a lot of drawbacks: It only runs in Google Chrome No Google Moon No Google Mars No Panoramio No Wikipedia links No historical images  No measurement tools I can't create new tours. The KML import is experimental and broken  No more creation of videos And I'm not alone, other peole are as disappointed as m: http://www.i-programmer.info/news/145-mapping-a-gis/10692-google-earth-reduced-to-a-divisive-toy.html

Here come the promised update. I've added text and the flight routs to the image: This time I'd like to thank the authors of this two YouTube videos to help me with Blender.    1. Text in Blender    2. Curves in Blender

Hello my latest little project is a 3D low polygon map. I used Blender and Gimp to create this map: I've started with an elevation map of Europe I found on the website from "The European Environment Agency" (EEA). Thank you EU for this image: http://www.eea.europa.eu/data-and-maps/figures/elevation-map-of-europe Then I had to cut of the black border with Gimp and created a second image as height map: For this step I converted the image to black and white and then used the curve tool to make the mountains darker. This will make the mountains in the final image higher and easier to discover. Then I used this tutorial to create the 3D image in Blender: http://johnflower.org/tutorial/make-mountains-blender-height-maps But I didn't  subdivide in as many parts than the tutorial ans I haven't smoothed, because I wanted a low polygon look of my image and not a realistic one. After this step I gave the plane the original colour image as textur...
