The Jasper and Kakadu based libraries have not been tested. The MrSID library is fast and successfully converts both NAIP and HRO. OSGeo4W comes with a GDAL library that uses the MrSID library. The ERDAS library is much faster and converts HRO successfully, but will sometimes fail to properly convert the NAIP. The version of GDAL that comes with FWTools uses the ERDAS library. This version is compiled with the OpenJPEG library and will successfully convert HRO and NAIP - but does generate a large number of error messages and takes a long time.
The directions for obtaining GDAL recommend a version hosted on GISInternals. Capabilities of the five libraries does vary and can lead to inconsistent results during the conversion process. Sorry, your browser doesn't support embedded videos.GDAL has five different libraries ( Jasper, ERDAS, Kakadu, MrSID, and OpenJPEG) that may be compiled into it for supporting JPEG2000, and does not compile one in by default. Note that some files are not compatible with universal file viewers and can only be opened in binary format. These programs can open many different types of files, so if none of the above tips work, a universal file viewer is the way to go.
When no other program will open your JP2 file, universal file viewers like File Magic (Download) are here to save the day. If you can’t open your JP2 file using any of the usual programs, you can contact the program’s software developer and ask them for help.įind your program’s developer in the list below: Nobody knows more about file extensions than software developers. Just right-click the file icon and select “Properties” or “More Info.” On a Windows computer, the file type will be listed under “Type of File” on a Mac, it will be under “Kind.” Contact a Developer You can find out which type of file your JP2 file is by looking at the file’s properties.
