I wonder if anybody has some experience in calculating biodiversity index (such as Shannon-Weiner) using QGIS?
I am also interested for similar experiences using R scripts within QGIS.
The analysis will use species count from individual stations of marine scientific surveys.
I have in mind to calculate the Shannon index of species diversity for each station of the sampling survey and then to "allocate" the average index within each cell of a vector grid or by interpolation in the Area of interest.
I wonder if anyone has experience in doing this using a spatial query (providing stations and vector grid are stored in a sqlite database)?
