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.
