About The Project

Inspired by mapant.fi, mapant.no, omap.nz, and recently mapant.es and mapant.ch, this website is a first attempt (as far as I know) to generate an orienteering map from a large amount of LiDAR data in France. This pilot project was made with territoire français du Grand Genève LiDAR data from 2014, and the BD TOPO database from the French Geographic Institute. I also used OpenStreetMap data for residential areas. This project was a way to get used with the LiDAR to map server workflow, while waiting for the full coverage of France.

I used the LAStools library of Martin Isenburg to manipulate the LiDAR files, and the awesome karttapullautin software of Jarkko Ryyppö to generate the orienteering map. I wrote Python scripts to orchestrate the processes, and to generate the tile pyramid.

This repository contains all the scripts used for the processing of LiDAR data. Below are all the steps of the workflow:

• downloading the files with lidar_download
• thining and indexing the files with lidar_thin_index
• generating PNG files with karttapullautin
• sorting the PNG files with lidar_sort
• generating the tile pyramid for the web portal with pullautin_to_tiles
