Data handling in QGIS

Make sure to have QGIS already installed and running in your computer. You can do this from:

Download the software from: QGIS

Do the following (pay attention to the buttons and steps)

1. Load the shapefile(s) of Angola (“ANG.shp” as a vector layer).
2. Load the shapefiles of the Angolan protected areas (“WDPA_Apr2016_AGO-shapefile.shp” as a vector layer)
3. Load the data table for the Angolan herps provided by Dave (“angola_herps.csv”; as a delimited text layer, comma-separated value table: ‘.csv’).
4. Open the attribute table of the Angolan protected areas shapefile’s (right-click on the shapefile and choose Open Attribute Table), then select the “National Park Iona” (you will repeat this for the “National Park Luengue-Luiana” after step 5).
5. Select the points/localities that are within each of the parks using the following sequence: Vector –> Geoprocessing tools –> Intersect. “Input vector layer”" should be tha “angola_herps” shapefile and the “Intersect layer” should be the protected areas shapefile. Be sure to check the “Use only selected features” tickbox. Finally, name and save a separate shapefile.
6. Export the intersected data from the Attribute table of the created shapefiles for each park records (steps 4 and 5). Select all data, copy and paste it into a blank EXCEL document and save it as a tab-delimited text file. NOTE: steps 4, 5 and 6 have to be run separately for each park.
