1. Database
1. Topografic layers (geographic info, maps, coordinates...)
2. Web application
GIS is not only a cartography!GIS is not only a cartography!
Complex GIS

4 steps of GIS establishment:
– System analysis
– Data analysis
– GIS design
– GIS realization

1. 1. System analysis System analysis
- define needs assesments – end users?
- define GIS application functionalities
- level of GIS establishment
- decision on software (we propose web application on ESRI ArcGIS server, database on SQL server)
- format of information layers (we propose shape or grid)
- geographic reference – coordinates (transformation, ETRS)
• result:result: specification of GIS functionality requirements

22. Data analysis . Data analysis
- determine minimum of data (survey of available data...conceptual model!)
- define all data layers
Without proper data analysis there is no Without proper data analysis there is no GIS design!GIS design!

3. GIS design3. GIS design
– software specification (ArcGis, ArcReader, AutoCAD, Excel, MSAccess...)
– relational database construction– information layers
Metadata! –– follow INSPIRE directive
• result: instructions for common GIS establishement

4. GIS realization4. GIS realization
- establishing of internet wiever – web application (ArcGIS server)
• result: functioning GIS application - portal

The SARMa GIS portal will contain a catalogue and a map viewer. The catalogue will be used to search for datasets using their metadata and consult the available mineral resources point data and maps in the viewer application.
Figure 1: SARMa GIS portal architecture
- SARMa GIS portal should allow visualization of common database and maps.

MAP VIEWER
The map viewer allows the user to:
-change the visible extent of the map (pan, zoom in, zoom out,…)
-manage the set of layers (visibility),
-consult the legend for the available map layers,
-perform an identify operation on the selected map layer (only one layer can be set “active”). -Query-Print-Legend display-Scale selection-Help
After identifying a map feature, a dialog will show some attributes of the selected feature on the map.
