How to make buffer by meter unit in a WGS84 Viewer

Question
HunD asked on March 17, 2017, keyword: Developer Kernel

Dear TatukGis  Team :

I have two layers i my Viewer.

One is Wgs84(4326) grid layer for displaying rainfall.
The other one is WebMercator(3857) for creating circle buffer by different meter every time.

If I use WS84 buffer layer and create circle buffer by degree, It works fine.

But I need to create buffer by meters, because same degree radius is different distance.

Could you kindly help me ?

Regards

Morris

Hi,

Check the function on TGIS_Shape.CreateCopyCS( [CS] )

l_buffershp_mercator := l_buffershp_wgs84.CreateCopyCS( CS of 3857 )
