Heightmap of Germany?

[Thoromir]

I am looking for a height map of Germany. Unfortunately, the maps are not sufficiently resolved when searching for Google. There is the possibility to create cards at https://tangrams.github.io/heightmapper/. But the result is too rough there too.Does anyone have any idea where there are highmaps for Germany that have a resolution of at least 2000 pixels in length?

You can use a program like paint to resize the image. However, tangram doesn't export a square image so you may need to crop it to get it as square as possible.

But if you crop a map, that doesn't change the low resolution :-)

After resizing, open with GIMP, under image, change to 16 bit grayscale, then under file, export and select 16 bit gray again. This should give you a working heightmap that you can import into the editor.

Sorry, that change anything about the resolution. :-)
You can't make a 4K Screen with a DVD Picture. You can zoom in, yes. But the image remains out of focus. You need a high resolution picture.

A heightmap isn't a picture, but a grayscale filter to import into a map.

As far as I am aware, TpF2 will only import 16 bit greyscale images, so that is the highest quality you can use.
The issue with the file exported from tangram is that it is something like 934x1049 pixels. I cant remember the exact dimensions off the top of my head. So, just converting this to greyscale and importing into TpF2 will result in the final map being distorted to make it fit the allowed ratios ie 1:1, 1:2 or whatever you selected. Therefore the image needs to be manipulated before converting to greyscale.
