Hi,

Can you please add a feature in Grass that can provide count of locations
present in defined range/radius of selected point.

Desired Feature can work in this way:

1. Selecting the layer.
2. Entering (or selecting) the coordinates of a point/location that are
present in the layer from the menu.
3. Defining the radius buffer info. (for e.g. 5 km or 5000 meters)
     3a. This option will further include two options:
      i. entering the integer
     ii. selecting the distance unit (km, meter, feet, etc.)
4. Generating the map display; (This should create radius circle from the
centroid of the point selected in the option).
5. Additionally, an output file(dbf or any other compatible file) should
generate that include the information about all points that appear within
the defined radius.

Thanks.

Comment:

v.distance? v.buffer + v.overlay/v.select? r.buffer + r.mapcalc? r.circle?
