My use case is very similar to http://docs.codehaus.org/display/GEOTOOLS/Guide+to+standalone+usage+of+interpolations . At the input I have points with coordinates and some data(simple double number). The distance between points is 30 meters. At the output I want to have interpolated image.
I`m iterating over outputted image and getting filled by interpolation 'intermediate' poitns(with the step 5 meters). Smth like that: TPSInterpolation interpolated = new TPSInterpolation(pointsAndValues, (int)stepX,(int) stepY, envelope); //and in loop interpolated.getValue(new DirectPosition2D(crs,currentX,currentY)); The issue is that interpolation is executing about 200 seconds with TPS method. As far as I understand, Nearest Neighbor algorithm should work much more faster with very similar result. So, it`s only the question of time optimization.
