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.

For example,

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.

  • load your csv into a spatial database and save time by using the spatial functions of the database. – Mapperz Mar 11 at 21:23

    If you wish to also ask about ArcGIS Desktop then please do that in a separate question. – PolyGeo Mar 11 at 22:03

    Did you work with spatial join and buffer ? – Hugo Roussaffa - GeoDatup Mar 11 at 23:28
