Raster data formats (GeoTIFF)

edited July 2014 in Library Questions

Hi!

Is there any working libraries for importing and manipulating raster data (e.g. from GeoTIFF) in Processing?

Cheers, Vesa

  • Is that gps data?

  • Nope, gps data is point data by nature but GIS-raster data covers a larger spatial extent. Raster data is produced by e.g. remote sensing instruments or simulation models. It differs from standard RGB-images in that it may contain any number of bands of any numerical data type (e.g. floats, integers, ...) and it also contains georeference information. Georeference information attachs a geolocation to the raster so that it can readily be mapped with correct pixel coordinates on a map.

    See en.wikipedia.org/wiki/GeoTIFF for explanation of GeoTIFF format.

  • No processing libraries that I can see, but there are Java libraries that you might be able to use.

    Thanks, koogs! Do you know any specific Java libraries that handle raster tasks? I've only used BEAM-API in Java, but it's way off the radar to use with Processing.

  • I found a post about this specific problem in Java: https://gis.stackexchange.com/questions/119134/looking-for-an-open-source-java-based-geotiff-library

    He references to this website: http://commons.apache.org/proper/commons-imaging/gettingstarted.html wehre you can get Apache commons imaging.

    But I couldn't find the file in this large directory. So I just found this ressource on Github: https://github.com/apache/commons-imaging

    Sadly I am not greatly familiar with java, so I am not really able to import the right classes and use them properly. But maybe someone else can figure this out.

    Btw: The example codes on the apache website are non-existent.

    Cheers
