#1493: wrong proj4text in spatial_ref_sys for SRID 4149
---------------------+------------------------------------------------------
Reporter: strk | Owner: pramsey
Type: defect | Status: new
Priority: blocker | Milestone: PostGIS 2.0.0
Component: postgis | Version: trunk

From: http://postgis.refractions.net/pipermail/postgis-
devel/2012-January/017805.html
proj4text entries for EPSG:1449 and EPSG:1450 are equal in
spatial_ref_sys.sql:
{{{
---
--- EPSG 4149 : CH1903
---
INSERT INTO "spatial_ref_sys"
("srid","auth_name","auth_srid","srtext","proj4text") VALUES
(4149,'EPSG',4149,'GEOGCS["CH1903",DATUM["CH1903",SPHEROID["Bessel
1841",6377397.155,299.1528128,AUTHORITY["EPSG","7004"]],TOWGS84[674.374,15.056,405.346,0,0,0,0],AUTHORITY["EPSG","6149"]],PRIMEM["Greenwich",0,AUTHORITY["EPSG","8901"]],UNIT["degree",0.01745329251994328,AUTHORITY["EPSG","9122"]],AUTHORITY["EPSG","4149"]]','+proj=longlat
+ellps=bessel +towgs84=674.374,15.056,405.346,0,0,0,0 +no_defs ');
---
--- EPSG 4150 : CH1903+
---
INSERT INTO "spatial_ref_sys"
("srid","auth_name","auth_srid","srtext","proj4text") VALUES
(4150,'EPSG',4150,'GEOGCS["CH1903+",DATUM["CH1903",SPHEROID["Bessel
1841",6377397.155,299.1528128,AUTHORITY["EPSG","7004"]],TOWGS84[674.374,15.056,405.346,0,0,0,0],AUTHORITY["EPSG","6150"]],PRIMEM["Greenwich",0,AUTHORITY["EPSG","8901"]],UNIT["degree",0.01745329251994328,AUTHORITY["EPSG","9122"]],AUTHORITY["EPSG","4150"]]','+proj=longlat
+ellps=bessel +towgs84=674.374,15.056,405.346,0,0,0,0 +no_defs ');
}}}
while they are different in proj4/nad/epsg:
{{{
# CH1903
<4149> +proj=longlat +ellps=bessel +towgs84=674.4,15.1,405.3,0,0,0,0
+no_defs <>
# CH1903+
<4150> +proj=longlat +ellps=bessel
+towgs84=674.374,15.056,405.346,0,0,0,0 +no_defs <>
}}}
Basically the code or CH1903 (EPSG:4149) seems bogus.
spatial_ref_sys is from postgis trunk.
nad/epsg is from proj4 trunk.
