Over the last few years, WebSIG have developed rapidly. Indeed, they allow the delivery of information and the « mutualisation » of data.

The mission consisted in producing a Webmapping application for municipal geospatial data consultation. The objective was to develop a web server application using open source technologies. This application is supposed to allow a better management and an easier information exploitation.

The set up of a Webmapping application is made easier thanks to proved open source applications. If, in this type of project, development competences are needed, the saving realised compared to software producers solutions potentially allows any interested organisation to equip themselves with this type of tool which would be adapted to their needs.

I had total freedom on this project right from the start and had room for manoeuvre in choosing the best suited application, the framework being already defined in the project specification. After the fast diagnostic phase related to the material and data, I had to work as an external provider.

There are currently four main open source solutions allowing to publish online geospatial data : static HTML, SVG, Java applet, map server architecture. The choice between the four of them is made easier thanks to their own limits and the heaviness of their display that allow to circumscribe each of them to a particular type of use and aim.

Eventually, the UMN Mapserver program and its PHPMapscript API were selected. After the compilation and integration phase of development environment and data, the next step consisted in conceiving a web client interface in accordance with the project specification as far as the navigation tools and the general ergonomy are concerned.

The interest of such a work lies mainly in the different steps that had to be taken in order to reach the objectives. Also, the choice of an application relating to MapServer allowed me to deepen my knowledge of that environment which remains the best known and the most used system in the Webmapping field.
