[mapserver-users] Mapserver and projcs in geotiff header
Hi all, just a feature check of Mapserver. Should Mapserver read the projection information in the geotiff header, if PROJECTION is not set in the LAYER def. of the map file? I'm testing with Mapserv 5.1-dev, and it's not working without PROJECTION, only when PROJECTION is set. I will soon try with a recent version of Mapserver (compiling). Here is my geotiff header (gdalinfo): Coordinate System is: PROJCS[Mercator WGS84, GEOGCS[unnamed, DATUM[WGS_1984, SPHEROID[WGS 84,6378137,0, AUTHORITY[EPSG,7030]], AUTHORITY[EPSG,6326]], PRIMEM[Greenwich,0], UNIT[,0.0174532925199433]], PROJECTION[Mercator_1SP], PARAMETER[central_meridian,0], PARAMETER[scale_factor,1], PARAMETER[false_easting,0], PARAMETER[false_northing,0], UNIT[unknown,1]] Origin = (-143878.103329198609572,7218088.338938739150763) Pixel Size = (75.000,-75.000) Metadata: AREA_OR_POINT=Point TIFFTAG_DATETIME=2010:09:21 14:32:57 TIFFTAG_MINSAMPLEVALUE=0 TIFFTAG_MAXSAMPLEVALUE=255 Image Structure Metadata: INTERLEAVE=BAND Corner Coordinates: Upper Left ( -143878.103, 7218088.339) ( 1d17'32.92W, 54d26'4.08N) Lower Left ( -143878.103, 6441988.339) ( 1d17'32.92W, 50d 9'52.31N) Upper Right ( 660946.897, 7218088.339) ( 5d56'14.59E, 54d26'4.08N) Lower Right ( 660946.897, 6441988.339) ( 5d56'14.59E, 50d 9'52.31N) Center ( 258534.397, 6830038.339) ( 2d19'20.83E, 52d21'4.61N) Band 1 Block=10731x97 Type=Byte, ColorInterp=Gray Mapfile (partly): MAP UNITS DD PROJECTION init=epsg:4326 END LAYER NAME mygeotiff DATA geo.tiff TYPE RASTER PROJECTION proj=merc a=6378137 b=6378137 lat_ts=0.0 lon_0=0.0 x_0=0.0 y_0=0 k=1.0 units=m nadgri...@null END END END cheers Jørn Vegard Røsnes ___ mapserver-users mailing list mapserver-users@lists.osgeo.org http://lists.osgeo.org/mailman/listinfo/mapserver-users
[mapserver-users] Polygon hatch mismatch at tile borders.
Hi, I'm using MapServer 5.4.2 and when I'm working with tiles the hatches of hatch filled polygons are not matching at tile borders. See example hatch_mismatch.jpg How can I solve that?

[mapserver-users] Polygon hatch mismatch at tile borders.
Thanks Alex, The gutter solution gives something better and the singleTile solve the problem. Unfortunately I can't use them, because we are pre-generating tiles in order to have good performances, which means that I need a solution at the level MapServer (Mapfile and / or symbol file). I've found that in The MapServer RFC Documentation http://mapserver.org/development/rfc/ms-rfc-45.html: - Polygon fill symbols Give hatches and vector fills a stable geographical coordinate origin (0,0) to better support tiling and continuous rendering of neighboring polygons - Does it mean that the problem is known and have been fixed?

And that it was considered in RFC45, but it is not clear from the RFC that it was actually solved as there is no bug number at the bottom that specifically tracks that particular change. This RFC was targeted for Mapserver 5.4. If you are on 5.4 or later then you might want to get a ticket opened asap, and maybe a fix can get put in 6.0 to resolve this.

However, you can setup a projection block like: PROJECTION auto END to automatically read the projection through GDAL. This is a little used feature, so it is possible it is broken now.

Not so accurate as the result with proj4 in PROJECTION enabled (map file), but it is probably due to the geotiff headers.

Yes, the problem is known and hasn't been addressed yet.
