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])
  • Linux, MacOSX [32bit/64bit]
  • running a (32bit/x86) Java Runtime Environment

Hint: make sure again that OJ is run with a 32bit java or in 32bit mode if it complains that the ECW libraries cannot be loaded.
