Isle of Mull

Bild
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:

G'mics 3D elevation plugin:

Water texture from here:

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

And a lot of fine tuning in GIMP, here is a screenshot of the layers dialogue:


Gimp now supports the HGT file format

Bild
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:

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 time. Export the HGT file a…

darktable geoToolbox Script

Bild
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 in one column and the distance between…

Lenovo Moto Z Wifi problem

If you owe a Lenovo Moto Z and it can't find your WLAN you should check if your WLAN uses the channel 13. If yes, just change it and your phone will find the WLAN, because the Moto Z is not able to use the channel 13..

Google Earth from a Tool to a Toy

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 ChromeNo Google MoonNo Google MarsNo PanoramioNo Wikipedia linksNo historical images No measurement toolsI 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:
