Hi Seth,
init=epsg:XXXX, as a way of doing a lookup in proj.db, is a legacy
syntax that was kept only in PROJ >=6 for EPSG. For other authorities,
PROJ only recognizes "AUTHORITY_NAME:CODE" for lookups in the database,
which enforces the order axis of the CRS definition (so EPSG:4326 !=
init=epsg:4326 since the former uses lat, long, whereas the later uses
long,lat). This might require changes in MapServer which is quite init=
addict.
2. Everything works if I create a text file named ESRI and put it in the folder in the
PROJ_DATA path. I also tried setting PROJ_DATA (and PROJ_LIB) to multiple folders to
allow me to put custom projections in a different folder - as implemented at [2] and
described at [3] - "Starting with PROJ 6, multiple directories can be specified. On
Unix, they should be separated by the colon (:) character. on Windows, by the semi-colon
(;) character."
However this doesn't seem to pick up the custom projection file on Windows or Linux e.g.
in the mapserver.conf file I set: PROJ_LIB
"C:/MapServer/bin/proj9/share;C:/Temp"
When setting through MapServer, this goes to a different code path using
proj_context_set_search_paths()/OSRSetPROJSearchPaths() which require to
have done the tokenization, whereas if you set it through a regular
environment variable, this is PROJ itself that does the tokenization.
Should be fixed per https://github.com/MapServer/MapServer/pull/6863
