ECW File format
ECW is a proprietary wavelet compression image format optimized for aerial and satellite imagery. See complete article about ECW in wikipedia.
ECW Read Support
An enhanced ECW support based on ERDAS ECW/JP2 SDK version 3.3 is available since OpenJUMP 1.4.3. It makes use of native libraries that were originally compiled by the gvsig GIS software team and shipped with their distribution. Thanks!!! One advantage of the new SDK is that it gives also access to JPEG2000 format. It is included by default into the PLUS edition of OpenJUMP. You can however add them manually to OpenJUMP CORE if you want to.
Requirements
As binary library code is used the support is platform specific. Currently tested and supported are
- Windows (XP,Vista,7 [32bit/64bit]) running a (32bit/x86) Java Runtime Environment
- Linux [32bit/64bit] running a (32bit/x86) Java Runtime Environment
Download
Download it here
Installation
Follow the instruction of the included readme.txt file.
- NOTE
- On Linux using the OpenJUMP Portable PLUS edition you currently [2012 June] have to do a manual step to enable ECW/JP2 support properly. Follow the instructions in
- lib/native/Howto_ECW_on_Linux32.txt
- If you use the jar installer this step is done automatically for you.
