I have some shp file in epsg:4326 and I want to repojeciton them to
900913, google's coordinate system. Because there are so many of them, using
org2org to convert them might be a big project.
So I put
"+proj=merc +a=6378137 +b=6378137 +lat_ts=0.0 +lon_0=0.0 +x_0=0.0 +y_0=0
+k=1.0 +units=m +nadgrids=@null +no_defs <>" in custom projection. But a
warning message showed that there must be a "ellips=".
Then I added the
# Google Mercator
<900913> +proj=merc +a=6378137 +b=6378137 +lat_ts=0.0 +lon_0=0.0 +x_0=0.0
+y_0=0 +k=1.0 +units=m +nadgrids=@null +no_defs <>
to epsg file. Still, the Google Mercator didn't show up in projection select
I googled for a while, some old posts suggested add it to srs.db. But I have
no idea how to do so.
Besides, I found little imformation about it through the net. Is it just a
silly question? Any helpful information would be appreciated.
