Qlik Sense Geo Analytics - Finding all possible coordinates from a list that falls within a certain radius of a point

[alidajvr]

Hi,

I need to identify which position coordinates (lats and longs) from a table containing position data falls within a 1km radius of a set of locations.  The locations are currently in a polygon format, but I am able to find the centre point of the polygon with the GeoGetPolygonCenter function.

The objective is to identify when a vehicle passed through a polygon location marked on a map.

I tried the Closest operator, but this only gives me the position closest to the location - not each instance when a vehicle passed through the polygon.

Here is an example of my data:

I hope the above description of my problem is clear.

Any assistance would be greatly appreciated.

Ok, severals ways to do that

1. Use the operation TravelAreas, transportation mode bird , distance 1 km for each of the locations to make circles around the locations.

2. Use the operation Within for each position towards the circles.

Or

The closest operation, transportation mode bird , max distance 1 km for each point to wards every location.

That is, if the locations doesn't overlap with 1 km.

(The order of the datasets matter, in this case first points then locations).

Thanks,

Patric

Thanks so much, Patric.

The first suggestion (combination of TravelAreas and Within) solved my problem.
