This page is about the MrSID support via MrSID console binaries. Alternatively you might want to try MrSID GDAL support provided by Referenced Image reader.

MrSID File format

MrSID (pronounced Mister Sid) is an acronym that stands for multiresolution seamless image database. It is a file format (filename extension .sid) developed and patented by LizardTech for encoding of georeferenced raster graphics, such as orthophotos. See complete article about MrSID in wikipedia.

MrSID OpenJUMP reader

Opens aerial or satellite photos in MrSid format (.SID extension).

This function is deactivated for default. To activate it user must copy the needed binaries into OpenJUMP as explained below.

Supported platforms

Tested and approved with OpenJUMP development snapshot [22/04/2013] for Linux (with oracle jre) and Windows with GeoExpress Command Line Utilities version (32/64bit). Should theoretically work on Solaris as well. These changes will be released in any version after OJ 1.6.1 .

for OpenJUMP 1.6.1 or older versions, see below

(2) copy all files of the bin/ folder of the above extracted archive into the lib/native/ directory of your OpenJUMP installation, eg. for Windows these are

    • mrsidgeodecode.exe
    • mrsidgeoinfo.exe
    • mrsidgeometa.exe
    • geos.dll

(3) Restart OpenJUMP and look if you can load the files

(4) Check the Window > Console output for errors in case the Open Dialog does not offer you to open *.sid files.

Old installation

Old OpenJUMP version : Up to version 1.6.1 (version 1.6.1 included), the default folder for MrSID executable was in lib/ext/ETC folder, and the default for temporary images was in lib/ext/ETC/TMP. You can check if the option to load "MrSID" files is offered in the file load dialog.
