You want to draw a complex poligon in your application, so how are the points
of the poligon defined, what datum etc.
There are many utilities to convert from one datum to another, or libraries you
could build into your application.

To be pedantic (a virtue :-), WGS84 is a family of specifications,,
which define not only the ellipsoid (same for all in the family,
thankfully), but also the positio
Hi Gabriele,
WGS84 is not a projection, it's an ellipsoid - a mathematical model of the
Earth. You are probably talking about the so-called "Plate carrée"
projection where latitudes and longitudes are mapped as X and Y values.
And this is a complicated thing because dX is different from dY (meridi
Hy all,
i'm developing a c++ gis using qgis api. I have a project in wgs84 projection.
I need to draw a complex poligon, so i need to find how is the pixel resolution
per meters, so i can find how many pixel are in 1 meters and use this value to
draw at real dimension.
How can i find the pixel
