Map Projection,(UTM) Universal Transverse
Mercator,PolyCal,No,AutoCalOnly,No,BSBUseWPX,Yes

With proj4 I get the projection of those points in UTM

$ proj +proj=utm +ellps=WGS84 coord
734345.05       4389843.39 (142,142)
741498.53       4390064.29 (5217,142)
741643.45       4385438.93 (5217,3422)
734485.67       4385218.08 (142,3422)

El objetivo es dadas unas coordenadas cualquieras dentro del mapa (p.e.
-0.269058 39.599662), obtener el punto x y en el mismo.
The goal is knowing a pair of coordinates in the map (for instance -0.269058
39.599662), get the x y pixel in the map.

$ proj +proj=utm +ellps=WGS84
-0.269058 39.599662
734484.83       4386888.69

How can I calcultate the X Y pixel for those coordinates having all this
data? Am I in the right way

Thank you very much

I have some .map OZI calibrated maps. From those .map, I can get some calib=
