Hello everyone! I am using GRASS with spgrass6 for my work. I will be using variograms in the process of landsat image classification. I am quite ok with GRASS but am finding R really tough. I understand that spgrass6 is a link between GRASS and R which can read and write raster/vector layers. Out of really many packages in R, for generating variograms out of landsat images which packages of R can be used? I...

...water package (0.5). As this is my first message to the list, I want to add that this package provides tools to estimate actual evapotranspiration from surface energy balance models. Right now you can run the well-know METRIC model using it. This model allows to estimate the energy balance using landsat (7 or 5) images and a weather station. I'll be happy to discuss or provide more information. Regards, Guillermo. ######################### The changes since the last version are: * Added maxit parameter to calcH to control the maximun number of iterations. * Added an optional constrain to...

I am attempting to classify pixels from a Landsat image by using their associated numbers in bands 2, 3, and 4 (It's from an assignment on classification). To aid me, I want to create a 3-D scatterplot using the "cloud" command. Due to my ignorance of the finer plotting functions, I am unable to display the scale on the three a...

Hello, I hope you can help me! I`m trying to tune svm parameters: cost and gamma for a landsat image classification, but I get an error and I can't understand it. I write this: > tune(svm, Class~., data = mdt01bis, ranges = list(gamma = 2^(-15:3), cost > = 2^(-5:15))) and R gives: Error en predict.svm(model, if (!is.null(validation.x)) validation.x else if (useFormula) data[-train...

Dear R users I am currently investigating time series analysis using an irregular time series. Our study is looking at vegetation change in areas of alien vegetation growth after clearing events. The irregular time series is sourced from Landsat ETM+ data, over a six year period I have 38 scenes. For certain periods I have monthly data while for others, images are up to three months apart. So far I have been using linear regression between NDVI (Normalized Difference Vegetation Index) and time to get an overall trend and then plotting the...

...DomU using the 2.6.26-2-xen-amd64 kernel my Dom0 uses, because that DomU is an entirely 32-bit Ubuntu, and the Dom0 is a 64-bit Debian kernel, right?

...T support for HVMs. Does anyone out there have packages for this, as I''d rather not bulk up my Dom0 with the whole GCC toolchain necessary to compile 3.3.1.

Greetings! Is there in any package for R which can help me generate madogram, rodogram, semi-variogram, cross variogram from landsat imagery. I intend to select portions of large imagery (i.e., obtain subsets) and generate the above said texture layers. A simple Google search led to me a result suggesting SpatialExtremes for generating madograms. However I am not sure about its capability to generate one for image layers. I am a...

...aptop in all of S-PLUS 4.5, 5.1 and pre-R-0.64.2. These are large (ca 50Mb per dataset). What `well' means differs between these systems. ##################################################################### ammann at utdallas.edu 1. I also work with remote sensing satellite data, mainly Landsat and AVIRIS. 2. I have found Octave to be very useful since it includes functions for reading unsigned integer data sets, and its handling of these very large data sets seems to be more efficient than R or S+, at least for standard matrix functions like BLAS, QR, and SVD 3. Various clustering algori...
