I’m looking for a ‘quick’ (in terms of my time, not computer time) solution to converting a whole bunch of ESRI Ascii Grid files into MapInfo TAB files consisting of a grid of points with XYZ fields. I’ve looked at GDAL/OGR but as far as I can tell GDAL deals specifically with Raster/Grid data (i.e. the source data I’ve got) and OGR deals with vector data (my desired output). I can’t seem to find any command to go from grid to vector though.
I have the following software available: MapInfo Pro, Global Mapper v15, QGIS, GDAL
I'm aware that both Global Mapper and QGIS are scriptable but I've little to no experience in writing scripts for either of these so am avoiding that given the time it would take to a) learn what I'm doing and b) actually write the script.
I have considered implementing the conversion in MapInfo's scripting language, MapBasic, with which I am quite familiar, but it tends to be a bit slow and given the large number of files I have I'd rather find something a bit quicker. I also don't have a huge amount of time to spend on writing up a script for this so would rather not reinvent the wheel if something already exists.
