I have converted my raster layer into the ascii file,but this type of data(Ascii file format) is unknown for Weka(A software for data mining and classification that recognize the Arff format),now how can I do this conversion?
Can I convert the raster file to arff directly?
Me and my friend have used this code in R but it didn't work properly.
library(raster)
library(foreign)
library(RWeka)
dir.satellite
Yes you can, but I cant help in coding, rather you can use Weka_Segmentation to view and do the classification. You can open the image in Weka_segmentation and create the training samples in .arff format, which you can open in Weka. See the following link: fiji.sc/Trainable_Weka_Segmentation
you can modify your text file directly by using the Wordpad to be acceptable by weka software.

.arff files are just plain text files with the appropriate header fields. You can edit them with a text editor (Notepad etc.).
Thank you all,I think I have found a better way using ArcGIS software,anyway I am thankful for your answers
Hi Ali,I am not good at english but I am very interested in your research about use weka to do classify with landsat. I am facing to the same problem what you used to face. So,could you please help me? I wander finally how did you input landsat to weka. Thank you and best wishes!
