I was playing with CountryData, and wanted to chart distance lines between my home and major European cities on a map.

I used the "Polygon" property of CountryData[] to get the country outlines of European countries, CityData[] to get lat-long of the cities I wanted, and Line[] to produce the lines. Finally, Graphics[] plotted all my output.

But given I live at latitude N45, the maps looked distorted, because they were simple lat-long projections onto a flat surface, I decided to explore some of the geographic projection options. CountryData["France", {"Polygon", "LambertConic"}], for example, does the job for the map of France, and worked well for all the rest of my target countries.

But I have been unable to figure out how to convert straightforward lat-long to the same projection, so I can place cities and my home. Combinations of GeoGridPosition and GeoPosition seemed promising, but they never hit my target projection correctly.

Also, the list of available projections in CountryData[] is not an exact mapping to those available in GeoProjectionData[]. For example, the latter contains options like...

"LambertConformalConic",  "LambertConformalConicNGS"

...whereas the former contains just...

"LambertConic"

Close, but no cigar.

Can anyone show me how to perform this transformation, both to and from?

Thanks in advance.
