Users often request for a simple way to test mapfiles. This RFC proposes a simple way to preview, test and navigate a mapfile with MapServer using a built-in OpenLayers based map viewer that will be triggered via the cgi. This is for testing/development purposes only and not for production or deploying full-featured sites. This will use the a built-in openlayers template. It will return a simple html viewer based on OpenLayers.
Note that GeoServer already provides a similar functionnality and this is what this RFC was inspired from.
In order to implement this enhancement, the following changes should be made in the MapServer codebase:
Add a built-in openlayers template.
Some new template tags will be needed. These tags will be used to construct the mapserver cgi url.
See ticket 3552 for more detail.
The template will be triggered using one of the following ways:
Both cases would call the same functions internally to produce a simple OpenLayers viewer with one singletile layer for the whole map with the selected layers.
Here’s the simple viewer html code that could be used:
Users will also be able to use their own OpenLayers library in one of two ways:
In the future, we may provide a mechanism to support multiple frameworks and ship generic templates with MapServer.
The ticket for RFC-63 (containing the implementation) can be found here.
