Tile Creation Prerequisites

Before we start creating our own tiles, we're going to need to go over some of the external programs and set-up to get our auto-generation scripts up and running.

To automate the tiles properly we're going to need a few programs.

  1. Starting with SASPlanet which can be found here: https://sasplanet.geojamal.com/2024/08/download-sas-planet-2024-explore-world.html

SASPlanet will be our primary source to grab imagery.

As of (07/07/2025) use the 3rd link there, the Download the Full Version with Fixed Map Errors.

Extract it to your desktop, open SASPlanet, press G and verify the google satellite imagery is visible.

  1. OSGeo4W can be found here https://trac.osgeo.org/osgeo4w/

OSGeo4W includes a variety of GIS tools, including GDAL which will be vital for re-projecting imagery.

When running the network installer select Express Install, for packages select GDAL and confirm.

If you can, it is ideal to install OSGeo4W on your C: drive, as this is the default path in the scripts (not a choice if Express Install is selected).

  1. ImageMagick can be found here https://imagemagick.org/script/download.php

ImageMagick is a very nice CLI image editor with a python hook called wand, when installing it should ask to add a new variable to PATH.

  1. If you don't have Python, now's the time to install it, https://www.python.org/.

I personally used Python 3.11.4, but other versions will probably work.

  1. Use pip install to download
wand
tiffile

  1. (Optional) If you don't have Visual Studio Code I'd highly advise you do that as well as it'll make managing the scripts incredibly easy. https://code.visualstudio.com/

  2. Nvidia Texture Tools, or NVTT, https://developer.nvidia.com/texture-tools-exporter

NVTT has a CLI interface allowing the automation of textures to DDS

It is required that you add the NVTT_export directory to the PATH, read here on how to do that https://stackoverflow.com/a/41895179

  1. TopoConv, the original source for which is here, only /bin/TopoConv.exe is required.

Navigate to that directory in the repo, click on TopoConv.exe and download using the button on the top right.

It's also required that you add TopoConv to your PATH, since you already added the NVTT_export directory to it you can just move TopoConv.exe there too.

Verification

  1. Verify SASPlanet runs and displays imagery
  2. Verify C:\OSGeo4W\OSGeo4W.bat exists
  3. Verify magick -help in cmd is recognized.
  4. Verify typing python in cmd enters python mode.
  5. Verify Wand and tiffile are listed after running pip list in cmd.
  6. Verify nvtt_export -h in cmd is recognized.
  7. Verify topoconv in cmd is recognized.

If all of these checks succeed, congrats! Download: https://github.com/RSS-Reborn/MTEv2/blob/main/_workflow.py

Place it in a folder you feel comfortable working in, in other sections this will be called your "work directory".

When using SASPlanet its highly recommended to follow these few steps to increase the download speed drastically.
