SYNOPSIS

map2gcm -q 1..100 -s 411|422|444 -t file file1 file2 ... fileN outputfile

DESCRIPTION

map2gcm is a helper utility for qlandkartegt(1) to convert a map to KMZ format.

The list of selected tiles is a string in a file. The index count startswith 0 at the top left corner and is incremented for each element in a row. A 2x2 tile selection will have the index string '0 1 2 3'.

The projection of the input files must have the same latitude along a pixel row. Mecator and Longitude/Latitude projections match this property. Transversal Merkator or Lambert projections do not.

To rectify a geotiff map, you can use the gdalwarp(1) command, e.g.

gdalwarp -t_srs "EPSG:4326" inputfile outputfile
