Convert Lambert to LAT and LONG

[Betty_sam]

Hi,

I want to convert Lambert (XY= (521387.001,204215.954)) to WGS84 ( LAT-LONG).

Any help plz ? 

Thanks in advance

Proc GPROJECT can help you with this. See the FROM= and TO= options. The SASHELP.PROJ4DEF contains some common values to be used for the FROM= and TO= options.

Here is an example on how to convert the swiss coordinate system to WGS84. You will have to lookup the proper values as needed.

By the way, where is the point you mentioned

data lv95;
  x = 600000;
  y = 200000;
  id = 1;
run;
proc gproject 
  data=lv95
  out=wgs84
  project=proj4  
  from="EPSG:21781" /* CH1903+ / LV95 */ 
  to="EPSG:4326";  /* WGS 84 */ 
  id id;
run;
