I'm trying to generate ARC/INFO ASCII GRID (*.asc) from point feature class using create TIN - TIN to raster - raster to ASCII functions. I'm looking for a way to have the output raster file header refering to center of left lower pixel instead of corner. (xllcenter/yllcenter instead of xllcorner/yllcorner).
Also I would like to know if the actual values for each pixel (height in my case, as I'm creating a DTM) depend on the information in header (if they are calculated for the center of pixel when xllcenter/yllcenter information are given in header). And related question - it is correct if I just rewrite the header from corner to center and change the coordinates to coordinates of center of the left lower pixel or is the height value for each pixel calculated also to corner of pixel?)
Thank you very much for answers.
