What map projections are possible

[Bruce Eglington]

Good day
what map projections oher than Mercator are possible with the map versions of TeeChart?

Hi Bruce,

TeeChart uses ESRI's shp files to create the maps as explained here: http://www.teechart.net/support/viewtop ... 725#p55070
But you are free to load any map you may find in the net. The map series is actually a list of polygons so there is no limitation on the shapes/countries proportions.

Hi Yeray
yes, I know that one can read in shapefiles but this does not control the projections e.g. Mercator, Mollweide, earth from space, etc. I know that Mercator is the default but would like to know whether it is possible to produce maps with one of the other projections. I could not find a way to do so in any of the map options but thought I had best check here on the forums.

Hi Bruce,

The only difference between projections (concerning TeeChart) is the list of points defining each polygon/country.
If you find a shapefile with a different projection than Mercator, I don't see why it shouldn't work or look as you'd expect.

Hi Yeray
Shapefiles do not contain projection information, only the coordinates for a series of points, based on a particular reference datum. All projection information in GIS is handled by the data frame, not the shapefile. As a result, it seems that one can not achieve what I want with the map series in TeeChart. It is unfortunate but not unexpected as TeeChart is essentially a graphing package, not a GIS system.

Thanks for your comments and help.

Hi Bruce,

Thanks for your comments and understanding.
I've added it to the wish list to be studied as a possible new feature in next releases (TV52016032).
