Well, here's a few interesting links what I've found with the help of a search engine : * http://pubs.usgs.gov/of/2003/ofr-03-230/DATA/ : several datasets in zmap format (.dat) and also the same datasets but in other formats that are already recognized by GDAL, such as .gxf, .ers, .xyz and .tif --> Very useful to check that a decoder for zmap works * http://lists.directionsmag.com/discussion/read.php?f=19&i=30467&t=30467&v=t : contains some bits of zmap content similar to the one of the previous link * http://arcscripts.esri.com/details.asp?dbid=13093 : import/export zmap plugin for ArcGrid with source code in visual basic > mostly it is used for DEM and petroleum and according to my > opinion it is descried by a rectangular kind of cells but it might not, > that's why I am asking for some reference for zmap format and > of course if it is possible to be adopted by gdal :) Although none of those links is a formal specification of the format, that should be sufficient for someone to write a decoder. But I'm not sure to understand your needs: do you have some zmap datasets that you need to read with GDAL ?
