Dear QGIS users, Do you know if the Interpolation Tool (TIN method) has a defined limitation in the number of points to be interpolated (or in any other limitation). I ask this because I have no problem in create a DEM using the Raster/Analysis/Grid (Interpolation) tool. But I when I try with TIN interpolation, I obtain a "empty" raster DEM layer with "nan" as minimun and maximun values. In both cases the shp file used as input has ~100.000 DGPS points, is it too big to be used with TIN interpolation?
I'm using QGIS 2.8.2-Wien in MS-Windows. Thanks in advance! Hernán
