Hi, I use gdal_grid to interpolate point data into grid data. I'm not able to understand how this command creates a regular grid. 1) Where is located the central point of the Search Ellipse shown in the "GDAL Grid Tutorial" respect to regular grid that I have to create? 2) In the figure attached there are some problems: why there are no value in cells in which there are points? Why there are values in cells in which there are no points?
Thank you in advance Marco
