How many map projections available in MWG? Like in tkMapProjection? If there are more, where are they?

Thanks!

Hello lang

The [tkMapProjection enum](https://www.mapwindow.org/documentation/mapwingis4.9/_enumerations_8cs.html#ad7975e2723bbf83d20e1820bb0020dd7) represents just the commonly used projections.

However, beyond those, you can use the GeoProjection class, and call [SetWellKnownGeoCS](https://www.mapwindow.org/documentation/mapwingis4.9/class_geo_projection.html#a74df7aa57ebdfc4c412fede6496e4401), with the [following enumeration](https://www.mapwindow.org/documentation/mapwingis4.9/_coordinate_01systems_8cs.html#a67e83d11410b054cde7bd62e2bd2ab95). Or use one of the various ImportFrom… functions, like [ImportFromEPSG](https://www.mapwindow.org/documentation/mapwingis4.9/class_geo_projection.html#a74df7aa57ebdfc4c412fede6496e4401), which takes the standard EPSG code as input.

So there are many options.

Regards,  
Jerry.

Hello @lang

I wasn’t sure what language you prefer, but here it is in c#.

```
        GeoProjection gp = new GeoProjection();
        gp.ImportFromEPSG(32615);
        axMap1.GeoProjection = gp;

```

Regards.
