Waking In The Night With Virtigo

GIS basics in the urban and regional planning exercise 5 "face recognition"

The aim of this exercise was an area accounting for various departments of the TU Kaiserslautern perform.

This adds to the first one on "Add vector layer" the Shape file tu_kl.shp. The attribute table for this layer is as follows:



summarize the multi-listed faculty selects the Tool "Geoprocessing" and then "Dissovle" from. The layer is now created, we TU_KL_Dissolve. Called the attribute table looks like this:



In the last step, click on "Tools", then "Geometry Tools" and "Export / Add geometry columns" and called the new layer "TU_KL_Bilanzierung. This was in the Attributtablle "AREA" and "Perimeter" added:



sees the end, the map of the University as follows:

Exercise 4 - GIS basics of urban and regional planning - spatial data processing



In this exercise was it is our task, the Special Areas of Conservation (flora and fauna habitat areas) and the bird sanctuaries in the counties and Bernkastel-Wittlich Birkenfeld present.

The first step was to set the project properties. The name of the project was "Natura 2000", the map units meters and KBS, the Gauss-Kruger zone 2 (31 466).

Next I have the maps of the administrative boundaries of districts, the Special Protection Areas and the Habitat areas of Rhineland-Palatinate inserted.
order the county boundaries of the two circles Birkenfeld and Bernkastel-Wittlich display, click with right click on the layer "LK_RLP" looks in the attribute table, the two counties and adds them to "Save Selection as a shape file" as a shape file new to the project ( LK_BIR_WIL).

was the next task to mark the bird sanctuaries that are affected by both counties. To do this you click on the top bar, select "Tools" then on "research tools" and then "selected by location. This will open a window where you above the layer VSG_RLP auswählt und unten den Layer "LK_BIR_WIL", dann auf Okay klickt und danach die Auswahl wieder als Shapefile speichert (VSG_BIR_WIL).
Danach sollten die FFH-Gebiete markiert werden, die von beiden Landkreisen betroffen sind. Dabei geht man genau wie oben beschrieben vor, nur dass man statt VSG_RLP, den Layer FFH_RLP auswählt. Die neu entstandene Shapedatei nennt man "FFH_BIR_WIL".

Als nächstes sollten die Vogelschutzgebiete/FFH-Gebiete oder Teilgebiete innerhalb der beiden Landkreise gesucht werden. Man klickt auf "Tools", dann "Geoprocessing Tools", dann "Clip" und gibt dann unter "durchsuchen" den gewünschten Namen der Shapefile (hier FFH_BIR_WIL_clip bzw. VSG_BIR_WIL_clip) ein.

The last to the Special Protection Areas and Special Areas for Conservation in the two districts are combined. For this you click again on "Tools", then "Geoprocessing Tools" and then "Union". Then choose from the two previously created clip shape files and rename the new layer as "FFH_VSG_BIR_WIL.

Now we will add, the card of Rhineland-Palatinate TK100 and makes them transparent to about 75%.

Finally, you click both "clip files" with right click on the Properties and placed under representation "unique value" and "GEBIETSNUM on" and click Classify.

click on layout to the card is in the groin to plugins , then click Quick Print, and then sets the Expression.
