Data-Base

The system allows making two types of consultations:

Thematic maps, which are pre-elaborated maps of each one of the 70 SCIAN cathegories contained in the SCIGA.

Detailed consultations, from the selection on three elements: economic activity, personnel employed (stratified in six groups) and geographical area.

Thematic maps

The types of thematic maps that can be produced are:

• According to the percentage of production units dedicated to the selected product (SCIAN cathegory).

• Control areas according to the percentage of agricultural area dedicated to the selected product.

• Control areas according to the percentage of social property agricultural area dedicated to the product.

• Control areas according to the percentage of non-social property agricultural area dedicated to the product.

It allows generating 4 types of maps, nationwide, in which each “control area” is colored according with how much a specific agricultural product is present in it.

Thematic map, example:

Exploitation of cattle for milk production per control area, according to the percentage of production units dedicated to the selected activity.
