Hello,
i would like use a lambert conformical conic. I though at EPSG 3035
ETRS89LAEA. But this one is centered on europe. I woulk like center this
projection on Saudi arabia. How to do that with qgis? Could you throw light
for me?
LAEA and LCC are not the same, although named after Lambert ;-)
EPSG: 3035 is defined as:
+proj=laea +lat_0=52 +lon_0=10 +x_0=4321000 +y_0=3210000 +ellps=GRS80
+towgs84=0,0,0,0,0,0,0 +units=m +no_defs
the lat_0 and lon_0 coordinates define the center of the projection. For
Saudi Arabia, something like
+proj=laea +lat_0=25 +lon_0=45 +ellps=WGS84 +units=m +no_defs
would be best placed.
If you rather want LCC, take
+proj=lcc +lat_1=20 +lat_2=30 +lat_0=25 +lon_0=45 +ellps=WGS84 +units=m
+no_defs
HTH,
André Joost
