I have problems using the function TIN(linear) interpolation in Qgis. The program crashes when larger areas is interpolated.
Map properties: vector map, Geometry typ = Point, features in this layer: 523851, EPSG:32633 - WGS 84 / UTM zone 33N, files = .shp
When i divide the map into more layer(like 80 000 points each) and then interpolate them together(by adding more layers in the interpolation meny), it works, except some areas still makes the program crash.
Any idea how to solve this? Or have someone had/have the same problem?
Maybe the problem is: can´t handle large files or the algorithm have problems triangulate between some points patterns.
