I did do just that but I believe there is a problem with execution order. If I set the Transverse Mercator projection manually then load a geotiff it erases my setting and I have to do it again. Then the calculated extents are quite incorrect (and they appear to be differently incorrect in the batch converter too). If I change the extents in the converter page then the resultant map is correct as viewed in grid settings. Of course I cannot do this in batch mode.

Additionally the main converter screen will not accept the same geotiff as the source image whereas the batch converter doesn't seem to care. I have to provide a png or jpg instead. See the image here...

I really want to convert all the NZ maps and host them for your users. For that I also need to know exactly how they should be hosted.

Hi, tazzydemon;

how to fill OruxMapsDesktop form:

1.-select the 'tiff' file with 'Calibration file' button.
2.-if all go right, the image file field should be automatically filled.
3.-introduce datum and projection.
4.-select destination directory.
5.-calibrate.

Use this last compilation (2.0.1beta) because there was a bug reading the grid coordinates (a + instead a - ).

please, try with your maps (I want to try, but http://www.linz.govt.nz/ is too slow, 5 hours for a 130mb file!).

So my question is, what is the specification for an online map server. Can you recommend some open source software and what projections do I need?
