[postgis-users] Adding custom projections

[Mark Volz]

Hello,

I would like to add a custom projection to postgis.  I have an ESRI projection file #103749 -NAD 1983 HARN Adj MN Lyon (US Feet), and the proj4js projection.  It appears that I also need to convert the projection into PROJCS for PostGIS.  How can I convert either the ESRI projection, or the Proj4js file into Proj4cs so that I can add a new projection in Postgis? 


Proj4js.defs["EPSG:103749"] = "+proj=lcc +ellps=GRS80 +datum=NAD83 +a=6378559.758 +b=6357173.65471281 +units=ft +lon_0=-95.8500000001 +x_0=152400.3048000000 +y_0=30480.0610000000 +lat_1=44.25 +lat_0=44.1955555556 +lat_2=44.58333333333334 +to_meter=0.304801 +no_defs";


Thank You
