I have a large data set with many columns of data where each row has data from a different lat/lon coordinate.
I would like to add land use at each site to this data set. I was thinking of using this data set (https://www.mrlc.gov/viewerjs/), but am open to others.
In QGIS, I would like to record the land use within a certain radius of each lat/lon coordinate, and have the proportion of each land use type at that point automatically go to the csv, which I will then use in R as a variable for a liner mixed model.
How might I do this in QGIS?
So far, I'm thinking it would be useful to create buffer around all the data points. I found the Fixed distance buffer command in geoprocessing tools, but am having a little bit of trouble because I want each buffer to be the same width across all latitudes, and I'd like that width to be in meters. All of my data is in the US and Canada.
