What is required to serve ECW images in ArcGIS Image Server?
Note: The ECW raster format is directly supported in ArcGIS Desktop, but not in ArcGIS Server, ArcIMS, or ArcGIS Image Server (the ArcGIS Server Image Extension). To use ECW in server-based products requires additional licensing permissions from Hexagon AB, who acquired ERDAS, Inc., the inventors of the ECW format.
For ArcGIS Server version 10, Hexagon AB provides the ECW for ArcGIS Server product. Once obtained, follow the product's directions to implement.
For versions prior to 10, contact Hexagon AB to request a license. Once the proper licensing is obtained follow the remaining directions. It is necessary to install several files and run a setup to configure the Service Editor and service providers. There are three DLLs required for ArcGIS Image Server to use ECW files. These are:
These binaries may be available from Hexagon AB, after purchasing a license for server-side use of the SDK.
Download and unzip the ECW.zip and run the ECW.msi. This installs the additional required files to support the ECW format in ArcGIS Image Server.
Note: These procedures allow access to ECW files. However, they do not allow data delivery by way of high-speed ECWP streaming imagery protocol.
Note: For more information, or further directions, see the InstallingECWplugin.doc or README.txt documents contained in the ECW.zip.
