Hello,
I figured it out… well sort of anyways. Since I could not figure out how to
reference the projection number I instead tried to include the underlying
parameters within my map file. It works without reporting any errors… but I
presume that this solution is not ideal.
MAP
PROJECTION
“init=epsg=3857”
END #Map Projection
LAYER
PROJECTION
"+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 <>" #Parameters for
ESRI 103749
END #Layer Projection
END #Layer
END #Map
Please let me know if someone has a cleaner way of accessing ESRI 103749
directly from the projection database.
Thank You!
Sincerely,
Mark Volz, GISP

or are you trying to import data from your ESRI service.
We (Jim) went a little different route here, we read the ESRI rest service and
stuff everything into a Postgres database as a cache and work against that. We
can set whatever EPSG that we need to this way for interoperability.

Steve,
I am using ms4w version 4.0.5, which I think comes with PROJ 5.20
Thank You
Hi Mark: Not something I've tried to do so hopefully someone else can weigh in.
What version of Proj are you using? --Steve

Hello,
Could someone help me with setting up mapserver to use a non ESRI projection
that is already stored in proj.db? The coordinate system is for Lyon County,
MN #103749 and is stored with ESRI as the authority. I know that we can set up
Mapserver to use Web Mercator by setting the adding "init=epsg:4326" to a
projection block. Unfortunately I cannot access my counties coordinate system
by setting the projection with “init=esri:103749”.
Thank you for any help!
Sincerely,
Mark Volz, GISP
