Problems with raster imageI need your help.
I made a MAP file with multiple images RASTER (GEOTIFF) but when MapServer Shows them, they appear dark. I copied a portion of the header and one layer to see as I'm generating the outputs. This is an example: OUTPUTFORMAT NAME jpeg DRIVER 'GD/jpeg' FORMATOPTION QUALITY=100 MIMETYPE 'image/jpg' IMAGEMODE RGB EXTENSION 'jpg' END LAYER NAME 'MyImage1' GROUP 'celdas3x3' PROCESSING "BANDS=3,2,1" OFFSITE 74 75 77 DATA 'image_1.tif' STATUS ON TYPE RASTER METADATA WMS_SRS 'epsg:4326' WMS_TITLE 'Celdas-3x3' WMS_GROUP_TITLE 'celdas3x3' WMS_FEATURE_INFO_MIME_TYPE 'text/html' END #METADATA PROJECTION 'init=epsg:4326' END #PROJECTION END #LAYER This is a capture the gdalinfo -stats

Re: Problems with raster imageHi,
It looks like you images really are dark (Minimum=0.000, Maximum=255.000, Mean=56.219, StdDev=21.179) You have two options: 1) Adjust images physically. Stretching pixel values (Mean +/- 2xStdDev) to use the full scale gives often reasonable result and it is the default in many viewers. In your case it would mean stretching values original values 14-98 to use full scale of 0-255. OSSIM image linker is one easy to use and open source WYSIWYG tool for performing histogram stretch almost automatically. Open EV can do the same and many other software as well. 2) Adjust the image on-the-fly with Mapserver. Have a look at SCALE and LUT in document http://mapserver.gis.umn.edu/docs/howto/raster_data/#special-processing-directives PROCESSING "SCALE=14,98" might be something to start with. -Jukka Rahkonen- -----Alkuperäinen viesti----- Lähettäjä: maplab-users-bounces@... puolesta: Germán CONAE Lähetetty: to 19.6.2008 14:29 Vastaanottaja: maplab-users@...

QuestionsIt is possible to connect mapServer with SQLServer? , How??? if it is possible, as it would have to be the structure of the table in which to keep the information thank you in advance Lic.
