Hello, I'm trying to diplay a raster on openlayers using wms. The problem arises on one of the rasters which on different zoom levels displays some tiles and the ones being displayed, doesn't correspond to the ones next to them.
For example on zoom level 15 this image is produced: https://i.imgur.com/OSaHxqc.png And on zoom level 16: https://i.imgur.com/omliU8v.png Mapfile: MAP EXTENT -64.3842958639 -34.2139046531 -64.3584069558 -34.1902071213 SIZE 470 532 PROJECTION "init=epsg:4326" END CONFIG "MS_ERRORFILE" "/tmp/ms_error.txt" DEBUG 5 CONFIG "CPL_DEBUG" "ON" CONFIG "PROJ_DEBUG" "ON" WEB METADATA "ows_name" "ec02s_medio-promedio_1" "wms_title" "ec02s_medio-promedio_1" "wms_onlineresource" "<host>?MAP=<mapfilepath>/ec02s_medio-average-relativeyield_1.map&" "wms_srs" "EPSG:4269 EPSG:4326 EPSG:3857 EPSG:32720 EPSG:900913" "wms_enable_request" "*" "ows_enable_request" "*" "wms_include_items" "all" "ows_include_items" "all" # "wms_feature_info_mime_type" "text/plain" "wms_feature_info_mime_type" "text/html" # "wms_feature_info_mime_type" "application/json" END END LAYER NAME "main" DATA "ec02s_medio-average-relativeyield" TYPE RASTER STATUS ON PROCESSING "BANDS=1" PROCESSING "APPROXIMATION_SCALE=FULL" OFFSITE 0 0 0 HEADER "../../mapfiles/templates/head.html" TEMPLATE "../../mapfiles/templates/main.html" FOOTER "../../mapfiles/templates/foot.html" INCLUDE '<mapfilepath>/ec02s_medio-average-relativeyield_1_ramp.map' PROJECTION AUTO END END END Rampfile: CLASS EXPRESSION ([pixel] > 4.78697947983e-05 AND [pixel] <= 2.19701147079) STYLE COLOR 255 0 255 END END gdalinfo on the raster: Driver: ENVI/ENVI .hdr Labelled Files: <rasterpath>/ec02s_medio-average-relativeyield <rasterpath>/ec02s_medio-average-relativeyield.aux.xml <rasterpath>/ec02s_medio-average-relativeyield.hdr Size is 470, 532 Coordinate System is: PROJCS["UTM Zone 20, Southern Hemisphere", GEOGCS["WGS 84", DATUM["WGS_1984", SPHEROID["WGS 84",6378137,298.257223563, AUTHORITY["EPSG","7030"]], TOWGS84[0,0,0,0,0,0,0], AUTHORITY["EPSG","6326"]], PRIMEM["Greenwich",0, AUTHORITY["EPSG","8901"]], UNIT["degree",0.0174532925199433, AUTHORITY["EPSG","9108"]], AUTHORITY["EPSG","4326"]], PROJECTION["Transverse_Mercator"], PARAMETER["latitude_of_origin",0], PARAMETER["central_meridian",-63], PARAMETER["scale_factor",0.9996], PARAMETER["false_easting",500000], PARAMETER["false_northing",10000000], UNIT["Meter",1]] Origin = (372480.000000000000000,6215920.000000000000000) Pixel Size = (5.000000000000000,-5.000000000000000) Metadata: Band_1=Band Math (b1/0.973546) Image Structure Metadata: INTERLEAVE=BAND Corner Coordinates: Upper Left ( 372480.000, 6215920.000) ( 64d23' 2.05"W, 34d11'23.72"S) Lower Left ( 372480.000, 6213260.000) ( 64d23' 3.47"W, 34d12'50.06"S) Upper Right ( 374830.000, 6215920.000) ( 64d21'30.27"W, 34d11'24.75"S) Lower Right ( 374830.000, 6213260.000) ( 64d21'31.65"W, 34d12'51.08"S) Center ( 373655.000, 6214590.000) ( 64d22'16.86"W, 34d12' 7.40"S) Band 1 Block=470x1 Type=Float32, ColorInterp=Undefined Description = Band Math (b1/0.973546) Min=0.000 Max=2.197 Minimum=0.000, Maximum=2.197, Mean=1.000, StdDev=0.336 NoData Value=0 Metadata: STATISTICS_MAXIMUM=2.1970114707947 STATISTICS_MEAN=0.99999959390852 STATISTICS_MINIMUM=4.7869794798316e-05 STATISTICS_STDDEV=0.3356240935974 If i comment the INCLUDE of the rampfile, the image is rendered pitch black, but the whole image is displayed correctly. _______________________________________________ mapserver-users mailing list [email protected] https://lists.osgeo.org/mailman/listinfo/mapserver-users
