In the final GIS exercise, it was the task which uses a part of Kaiserslautern on an aerial photo digitized. This was "digitized polygon" with the help of function possible. After being digitized, the polygon was a query, which of the different uses:
* Other * Municipal
* Agriculture * Forest
* Sport and Recreation,
meets the polygon.
This could be done for the entire planning area, so that the whole air was digitized image.
was then using the function "resolve" the use of combined classes creating a new layer was created, which I have "use balance" mentioned.
Note: In case the function "dissolution" there has been a mistake, so that the entire traffic area not considered was
The last step was in keeping the surfaces of the individual uses for the layer "use record" calculate . But you have mentioned in the layer attribute table to open and use the field calculator. It had to make sure that is specified as the output field name "space", and an output field type "real". Then confirm as an operator "surface" and ok. Then we had to open the field calculator for a second time mit den selben Funktionen nur diesmal bei Felder "Fläche" benutzen. Dann wieder mit ok bestätigen und in der Attributtabelle waren die Flächengrößen der einzelnen Nutzungen zu finden. Jedoch fehlt auch hier der Verkehr, da dieser nicht mit aufgelöst wurde.
Die Übung kann in gezippter Form hier heruntergeladen werden.
