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

Installation

Follow the instruction of the included readme.txt file.

NOTE

On Linux you currently [2012 June] have to do a manual step to enable ECW/JP2 support properly if you use the OpenJUMP Portable PLUS edition. Follow the instructions in
