Correctness of contour is a simple matter, except for one thing. That is
the issue of saddles.
That issue cannot be solved correctly since typically the data can be
interpreted in several ways.
This is also described in a wikipedia article (google for it, if you

I don't know about the gdal routines specifically, but:
1. Re. dem/dtm generally, the most significant factor in interpolation
results is the quantity (density, really) and quality of the source
data, not the interpolation algorithm.
2. Re. contours generally, they are cartographic
Am creating an app which correctly calculates contours from a DEM file or any
height-map given to it. The correctness of the contour holding the most
importance, since a person viewing the contours shouldn't end up taking
wrong planning decisions and maybe losing their life by the route they
