6.1. GIS module overview

You can access the GIS module from the Services -> GIS link in the top menu. The picture below shows the GIS viewport.

On the right hand side there is a panel called "Map layers". There are three available "base layers", which means background map, including OpenStreetMap and Google Maps. You may click the text to open a context menu that lets you adjust the opacity/transparency of the background. "Overlays" are described later in this chapter. The final four layers are the vector layers which the user has at his disposal for thematic mapping. You may use this layer tree to show/hide layers by checking/uncheking their checkbox. The next panel called "Cursor position" tells you at what longitude and latitude your mouse cursor is positioned. The "Feature data" panel provides you with quick information on the organisation units you mouse hover in your thematic maps. Finally there is a legend panel for all the thematic layers.

The picture below shows the map toolbar:

The "Map" buttons from the left: "Zoom in", "Zoom out", "Zoom to visible extent" (all thematic map data fits inside the viewport).

The "Layers" buttons from the left: "Thematic layer 1", "Thematic layer 2", "Facility layer", "Symbol layer".

The "Tools" buttons from the left: "Favorite map views", "Predefines legend sets", "Export map to PNG", "Measure distances on map".

The two final buttons are "Administrator settings" and "Help".
