Note: This post is about getting ecw and mrsid support working in the trunk (qgis-dev) version of QGIS which is installed with the OSGeo4W installer. Non-dev versions seem to work fine following this method: Getting ECW and MrSID support into QGIS can be a real pain in the butt when you first try; but once you know how it’s easy. If you try to open a ecw file in QGIS you will get this nice little error message: What?
I thought QGIS supported ECW files! Turns out it does, but the team are not able to ship the required libs with the program due to licensing restrictions by ERDAS. Luckily adding support is not “too” hard. • First head over to • Click Download Now for the ERDAS ECW/JP2 SDK Desktop Read-Only, Version 4.1 libs, • Fill out a bit of registration details and click though all the pages ( this is the most painful process I have ever had to go though to get some libs for a program, ERDAS should be ashamed that it is such an effort.) • Once you have download ECWJP2SDKSetup_RO_20100920.exe; install it. • Copy all the files from C: Program Files ERDAS ERDAS ECW JPEG2000 Read SDK bin vc90 win32 into the bin folder of your OSGeo4W install (default is C: OSGeo4W bin) You can open the OSgeo4W shell and run: copy “C: Program Files ERDAS ERDAS ECW JPEG2000 Read SDK bin vc90 win32 *.dll”%OSGEO4W_ROOT% bin to do the same thing. • Launch osgeo4w-setup.exe, the installer that you used to install qgis-dev, and select gdal-ecw, gdal17-ecw and gdal-mrsid, gdal17-sid under the libs section. Let it install the needed libs and any dependencies.
For ArcGIS Server version 10, ERDAS provides the ECW for ArcGIS Server product. Kd Max Crack Keygen Pes. Once obtained, follow the product's directions to implement. For versions prior to 10, contact ERDAS to request a license.

• • Your layer is an ECW format raster. By default, the ArcGIS for Server installation does not include support for ECW format rasters. Layers based on the ECW format will not draw without the proper support.
Solution • Convert the ECW-based raster into a file or enterprise geodatabase and replace the ECW-based layer with the geodatabase layer. • You can also choose to copy data to the server. In this case, all data referenced by your layers, regardless or their original data source, is consolidated into a single file geodatabase on the server. This requires a connection to the server where the option to copy data is checked.

The server will not draw the layer until the proper license is installed. More information Enhanced Compressed Wavelet (ECW) is an ERDAS ER Mapper proprietary format. It is a wavelet-based, lossy compression, similar to JPEG 2000.
ECW raster format is directly supported in ArcGIS for Desktop but not in ArcGIS for Server or the ArcGIS Server Image extension. To use ECW in server-based products requires additional licensing permissions from Intergraph. To contact Intergraph to request a license, send an email to sgilicense@intergraph.com. Once a license has been granted from Intergraph, it is possible to enable ECW support in ArcGIS for Server and the ArcGIS Server Image extension.
