Hi,

I'm new to rapid miner and novice in data mining. My objective is to automatically extract the land use land cover features (Water bodies, Built-up, trees etc.) from the satellite imagery (Worldview-2). I've installed rapid miner with Image processing extension. Can anyone help with the following questions please?
1) Is there any tutorial or help documentation available specific to satellite image processing?
2) How can I use Tiff files as input? (I understand Jpg and png are supported)
3) How can I use CART (classifiaction and regression trees) on images using Rapid miner.
4) Is there any developed workflow?
Appreciate any help.
Thanks in advance...
Regards
Suresh

    Hello Suresh,

    to work with images in RapdiMiner you can check this presentation (http://spl.utko.feec.vutbr.cz/images/stories/rapidminer/rmx_image_1_1/burget_radim.ppt) to get better idea about the most significant features of image extension.
    1) Unfortunately there is no documentation specific to satellite image processing available. The extension is quite new and
    2) Tiff images are not currently supported by the extension. you can convert the data to a supported format or contact developers of the extension to add this support
    3) You can extract features from images and then you can work with the data as is quite common in RapidMiner.
    4) Currently the set of examples how to use IMMI is being prepared

    If you would also need a professional consultancy you can request it on authors' website http://spl.utko.feec.vutbr.cz/.

    Hey Suresh,

    could you solve your problem? As I have the same questions!!
    My task is to find the right trasholds for a classification of a multispactral image.

    Thus especially the point: "(You can extract features from images and then you can work with the data as is quite common in RapidMiner)" i´m really interested in.

    greetings
