7.2 Definition of the order’s geographic extent

In the 2nd step, the user has to define the geographic extent on which he wants to order the selected product. To do so, the geoportal offers several “order extent types” among whose the user may choose. The number and sort of these extent types depend on the product. For example Act’s 1/20000 map is sold only following the fixed TC20000 map sheets.

To be oriented in the geography, a mini-mapper is available offering the most elementary navigation and location functions of the main mapper.

If the user changes the extent type after a definition has already taken place, the procedure is initialized and a warning message appears :
