[Qgis-user] raster layer combination

[Milena Muehler]

Dear community, 

as an absolute beginner I try to explain my issue and intension. 

So I have several raster layers (population density; livestock density; mammal density; etc.) and two text layers (so I've imported two csv files with longitudes and latitudes into QGIS and now I have points about the location of large airports and location points where there was a zoonotic infectious disease outbreak). 

My intention is to „combine“ all layers and to get all the values under this specific point of an outbreak. So that I have the exact value of the population density, livestock density ans so on where the outbreak occurred. I guess I have to make the calculation within a certain vicinity though. 

I hope you can understand my intention… 

Now I was wondering which function I have to apply. Something like „generating random raster grids“? 
 If so, which one exactly and what do I have to consider then. 

In the end I want to have a file as an output with values to make regression analysis in SPSS. Which means I was wondering if I can generate a kind of table with values with my intended raster combination. 

Hope you can follow somehow what I want to analyze. 

Thank you SO MUCH! 


All the best
Milena
