# Geo Picking Data
|
||
|
|
|
||
|
|
These tools were used to generate data for both
|
||
|
|
[the article on aligning HTML elements to 3D](https://threejs.org/manual/en/align-html-elements-to-3d.html)
|
||
|
|
and [the article on using indexed textures for picking and color](https://threejs.org/manual/en/indexed-textures.html)
|
||
|
|
|
||
|
|
I'm not going to go into details on how they work but you can look inside
|
||
|
|
and see them draw the images and extract the data. Maybe you can use them
|
||
|
|
to make or extract similar maps from other data.
|
||
|
|
|
||
|
|
The one I actually used is `make-geo-picking-texture.html`. To run it you need
|
||
|
|
to download the data from [here](http://thematicmapping.org/downloads/world_borders.php)
|
||
|
|
then unzip it and put it in this folder.
|
||
|
|
|
||
|
|
Then run a simple server. If you don't already know how to do that [here's a simple one](https://greggman.github.io/servez/)
|
||
|
|
that will take just a few clicks to use. Run it, point it at this folder, then load `make-geo-picking-texture.html`
|
||
|
|
in your browser.
|
||
|
|
|
||
|
|
There's also another one called `make-geo-picking-texture-ogc.html`. It works with data from
|
||
|
|
[here](https://gadm.org/download_world.html). To use that one download the database then use
|
||
|
|
a tool like [https://sqlitebrowser.org/](https://sqlitebrowser.org/). Open the database and
|
||
|
|
export the table called `level1` to a json file called `level1.json`
|
||
|
|
|
||
|
|
Then run a simple server like above and open `make-geo-picking-texture-ogc.html` in your browser.
