In this case we will be doing a quick spatial analysis of species observation data downloaded from the Living Atlas of Australia website.
In this case I have downloaded all the resorded sitings of echidnas in Kakadu NP. We will quick do an analysis of the number of sitings in each habitat type. To do this we need to reporjuect the echnidna siting data so it is in the same format as the habitat data.
Use the reproject layer tool:
Project to GDA94/Australian Albers
Now use the Processing Tool box to search and search for the Point Statistics for Polygons tool:
Note that this is actually using a tool from SAGA GIS. QGIS enables seamless integration of tool sets from another other geoprocessing packages such as SAGA-GIS and GRASS GIS.
Enter the rep[rojected echidna point data and the ‘collected’ habitat data.
The attribute table of the resulting vector layer will show the number of sitings for each habitat type.
