Description

Hi,

I was using Concaveman to find the border images when the geolocations are not in a specific patern then it work very well but it fails if the points are in sepecific pattern as attached in the image. I tried changing the concavity but didn't work. I was using concavity of 2 and lengththreshold of 0for all the dataset since my data points would of smaller area and closed together.

Attached image is a where sample points are linear towards Y axis.

GeolocationData

could you look and suggest.

Research direction

Start by reproducing the reported failure in Concaveman with geolocation points arranged linearly along the Y axis, using concavity 2 and lengthThreshold 0. Compare the result with a non-linear point set and vary those parameters to isolate the behavior. Done means the border points are correctly identified for the reported linear dataset, or the limitation is clearly documented.
