[postgis-users] equal-area projection for southeast Asia

[Dane Springmeyer]

Neil,

I don't know of anything standard, but lambert and albers are what  
come to mind.

There are the esri-crafted albers projections for asia that do not  
have epsg listings but might be useful references.

See the esri Albers options here:
http://spatialreference.org/ref/epsg/?search=GCS_North_American_1983 
+albers&srtext=Search+WKT

At www.spatialreference.org you can also find these customized albers  
projections that could be helpful for ideas on crafting your own:

Finally, while esri has not crafted asian lambert projections like  
albers these still might be useful:

Cheers,
