I have two sets of data. One that is from a csv and contains a relatively small amount of data (we will call location data), and another csv that contains a larger dataset that contains environmental data.
I want to create a separate csv file that contains all the environmental data that is within 1 km of the location data.
If temperature data comes within a 1 km radius of 1 or more points from the locations data, I want to create a new file that contains all the data that is in that 1 km radius.
How should I go about doing this using QGIS?
See the image I attached. The pink points are the location data and the small points is the environmental data. I only want to look at the data that overlaps with the pink.
Keep in mind the pink data points are styled and there is a 2000 m diameter.
