Nasa topographic data

Nasa is a great general source for earth related maps be it weather, temperature, or topographical. In the following source we can get some height maps of earth: https://visibleearth.nasa.gov/images/73934/topography

This source is great for topographic data of larger regions i.e. continents or whole countries. 

You can one image of the entire planet or eight divides one with higher resolution

Map integration

 Web Map Interface: There are a number of ways to implement a map on the map. The option most known is probably with google maps API. We will not go with this option in this application but go with Leaflet . Leaflet is open-source and has all features most developers need. We will also be using  Tangram , as mapping engine. This will allow us to fully customize the look of our map, including a custom elevation map. Now we have an interface to show the map, an engine to change the look fully all we need now is map data. Here too there are different option but keeping with the open-source theme we will be going with OpenStreetMaps . More specifically Mapzen which is the tangram integration for OpenStreetMap.  Our map interface has two main functions, Show a map with elevation data and letting the user select a region they want. We'll start with the latter with this code: 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 <div id= "m...

Project concept

Image
In this blog we will explore the possibility to create custom STL files based on topographic data sources via a web interface. General workflow: The user will select the the wanted terrain via a map interface, here he will set the coordinates and radius of the map. These properties get send to the web server which will request a height map from the corresponding data source. This can be via a API request or in a internal file.  The webserver launches blender via a terminal command a launches the internal python script. This script will get the height map and needed model properties After the python script has been processed blender will export a STL file and render a image of the model. The render part may be optional The webserver fetches the STL file and optional rendered image and sends these through to the web interface. Now the user can preview the model via the rendered image and download the wanted STL model. The currently planned development process for this ...
