Swiss coordinate system data

[r.pa...@gmail.com]

I'd like to use JFlowMap with projected data (ie. XY coordinates instead of lat long). My data are points in the data is in Swiss coordinate system (SRID 21781).

Which map.projection property should I choose? And what exactly is 'FlipY' projection?

Thanks for help,
radek

Hi Radek,

JFlowMap doesn't have any special support for preprojected data. You will have either to convert your coordinates to WGS84 or go with what you have and plot the data unprojected with either "none" or FlipY projection. The latter just flips the y coordinates of your nodes. 

Regards

Ilya
