GeoReferencer

An open source, stand-alone web application for georeferencing images, with very simple interface. GeoReferencer converts (scanned) images of maps (JPEG, TIFF, PNG) to GeoTIFF by allowing the user to select reference points on current maps (OpenStreetMap, Google Map or custom).

Developed by Picturae B.V. for the project Erfgoed & Locatie ("Heritage and Location").

Development setup


The development setup requires only docker & docker-compose > 1.7 present on the system. You can install these tools via your package manager. On the Mac you can use docker toolbox or install the tools via brew. See https://docs.docker.com/ for more information regarding installing docker for your platform.

It sets up 3 docker images - a webserver (with Gdal tools cli compiled & installed), an asset builder and a geoserver.

Steps to setup a development environment:

  1. $ git clone https://github.com/picturae/GeoReferencer.git ./geo
  2. $ cd ./geo
  3. $ docker-compose up
  4. Edit your /etc/hosts file to point georeferencer.dev, georeferencer-api.dev & geoserver.dev to the IP of your docker host. E.g. add:

<docker ip> georeferencer.dev georeferencer-api.dev geoserver.dev

Dependencies are automatically fetched & installed. If you want to add a new one, simply remove the node_modules folder and up the containers. Also you need to add <script type="text/javascript" src="//maps.google.com/maps/api/js?v=3&sensor=false"></script> in your html.

NB: If you get a permission error regarding node_modules and sass_cache. Just remove the folders manually and run docker-compose up again if the containers are not launching.

Bonus

Get familiar with the docker commands.

docker-compose rm, docker-compose stop, docker-compose build & docker-compose up are your friends!

Configuration


It is possible to alter the configuration on the tool to allow it to run in your own environment.

By making changes in app/app.cfg you are able to alter the parameters used to configure where the hosts are running and where the geoserver can be found. Changes made to this file and the nginx site configuration files in resources/gdal/sites-enabled will allow you to either change the ports used, use existing installs of the tools or allow you to configure the system to run using different hostnames.
