I have a map of a country with the location stores within the country (a store identifier and the coordinates of the store). I want to:
- Create a grid over the map (say, 2 km by 2 km).
- Create an index to identify all stores that are located in the same cell of the grid.
- Export the resulting data (store identifier, coordinates, and cell identifier).
How do I do this in QGIS 2.18 on Ubuntu 16.04?
