A tweak in MapServer code would be required to accept syntax like "ESRI:XXXXX". The +init=epsg: stuff that is a compatibility syntax which only works for EPSG.

Hello,

I am having trouble trying to reference ESRI authority coordinate systems that are within proj.db within MapServer.   I know this should work because I can use the QGIS can use the ESRI authority coordinate systems and QGIS apparently uses the same proj.db database as MapServer.  I tried referencing the projection using init=esri:103749 and init=epsg 103749.  Neither option appears to work.  I can however manually and the projection parameters.

Here is a snippet of my code:

MAP

PROJECTION

"init=epsg:4326"

END  #Map Projection

LAYER

PROJECTION

#WORKS

"+proj=lcc +lat_1=44.25 +lat_2=44.58333333333334 +lat_0=44.19555555555555 +lon_0=-95.85000000000001 +x_0=152400.3048006096 +y_0=30480.06096012192 +a=6378559.758 + b=6357173.65471281 +units=ft +no_defs  <>"

#Does not work

“init=esri:103749”

“init=esri:103749”

                                End  #Layer projection

                END #Layer

END #Map

Please let me know if you have any thoughts regarding how we can use ESRI authority projections.

Thank You
