Hi,
I am using a Belgium map of size 844x598. I tried all the methods
mentioned in the forum to convert the latitude/longitude to pixel
coordinates, but it is not coming correct.
Can anyone help me?
Thanks

Use the map calibration screen in Oziexplorer and your exact pixel co-ords
will be displayed in the top right corner of the screen. |

.. . . but even with OZI you have to calibrate first (Projection,
MapDatum, Grid?)

No, as you click the mouse on a given point in the calibration screen, it
gives you the pixel co-ords, you must kinow what the lat/long co-ords are
for that point, but then, if you don't know at least one set of parameters,
how can you define the others?

That sounds like very few pixels for a place the size of Belgium.
Perhaps a better map would be the way to solve this.

Thanks from a lurker. I'd never heard of Oziexplorer, and it does
just what I want to do. |
