Do you can guide me Removal cloud by Erdas or Envi...? I dont known method to do it. Thanks for feedback!

@Rahmansunbeam. I want removal Cloud from Landsat Image. But i cant method and software to do it. I hear everybody talk about LEDAPS. This software run in Linux. I dont known LInux and install Ledaps in Linux. Rahmansunbeam, do you help me install Ledaps (tutorial..., guide)..or you can guide me removal cloud by another software? Thank you very much!!!

Yes, the file is live. We can disable virus before downloading it!

Regressions in SPSS is Normal. We can choose: Linear, Logistics, Curbic (Non - Linear) for simulating correlation between 2 raster. step1: You make sample (than 30 sample) from Land use and Land Surface Temperature. step2: You extract value of point from sample. Step3: You use: SPSS or Statistic software (R software, statgraphics, spss....) to make correlation. Step4: You use Gis software for compute raster (Multiply, split, add, subtract follow equation in step3). Good luck!

the more the better!!!! :D

someone can help me? how to use toolbox Feature extraction in Envi 5.0. Toolbox doesnt work in Envi 5.0 (Medicine created by hero Lomex).

Hello everybody! When i classify object oriented image in Envi 5.0, I use feature extraction. The result is error. I use vitamin (medicine is created by Lomex). http://peupload.com/images/319error.bmp If some one know problem/solution. Please help me! Thank you very much.

Thank my friend. Now i was understood the problem. Many thanks.

I dont find tools in Arcgis. I only see: IDW, Kriging..... Not seen K nearest neighbour and Regression Krigging.

@rahmansunbeam, you can scan hard copy to pdf. The ebook is useful for student who study about remote sensing.

700 usd. It is expensive. i like Nokia phone. It is cheap, enduring, strong....

@alien786. I am finding it but not found. It is useful book. Hope somebody can share it. You can search ebook remote sensing at: http://bookos.org/s/?q=Physics+Remote+Sensing+of+LAndscapes+with+Spectral+Images%3A+A+Physical+Modeling+Approach&t=0 http://filesnail.com/?key=Remote+Sensing+of+the+Environment&filetype=all-files

Arhanghelul, My friend! You can see at: http://earthexplorer.usgs.gov/ . Before you must registry free nick at this site. You Chose Data Sets - NASALPDAAC Collections - Aster Collections - Aster Level 1B. next step: You choose the place where you need download image at Search Criteria. at the end: You download Aster image. Good luck!

I have search the tutorial that is Created By: Grant J. Firl, Lane Carter. It is interesting tutorial about Calculating Vegetation Indices from Landsat 5 TM and Landsat 7 ETM+ Data. Everybody can download at here: http://ibis.colostate.edu/WebContent/WS/ColoradoView/TutorialsDownloads/CO_RS_Tutorial10.pdf Source: Colorado state University

My friend! You said true. I have fixed this problem. The result is good!

Hello every body! I study topic: Estimation forest base on K nearest neighbour and Regression Kriging method. I search in internet and literature about K nearest neighbour and Regression Kriging. They use R software to process. I know little about it. I want use another software to process. Example: Arcgis. I dont know Arcgis can process it? If someone know how to process K nearest neighbour and Regression Kriging in Arcgis. Please help me (stuff, tutorial or guide....). Regard.

These literature research about forest in my country. When i calculate NDVI index in my Landsat image, the result is bad. Value index is low: 0.2-0.3. The rich tropical forest have high value of NDVI (usually: >0.5).

Hello every body! When i calculate NDVI index of Landsat ETM image. I use function: NDVI = (IR-RED)/(IR+RED). The result is not exactly. The NDVI of Rich forest = 0.2-0.3. Infact NDVI of Rich forest >0.5. I use Erdas, Envi... for calculation but the result is bad. The data of mine: Landsat ETM 2003. If someone know solution, please help me. Thank you very much. Regard

Thank Yousef!

Thank Rahmansunbeam. That i have read in previous. These sample in Tutorial that is choosen by select sample method. But in my option these sample is created base on shapefile vector. I use method classification in that tutorial but the result is not successful. What method to classify image base on these sample, that is created from shapefile vector? thank you very much.

Hello everybody! I am studying about Ecognition at Chapter: Creatting Samples base on Shapefile. When i finish creat these samples from vector (thematic layer: Shapefile). Now, How to classify image base on samples? if someone know that. Please help me! Thank you very much.

Arhanghelul. You can use Mike DHI 2011 or 2007 instead of that tool.

Thank sumpuaro very much!

Hello everybody! I ask everybody how to classify object by Ratio: "what does these Ratio use in classify image in remote sesing?" I only know NDVI, SAVI...: (Water NDVI<0, Vegetation: 0.2<NDVI<........ )What ratio else?

Yes, exactly. But i used Toolbox: Polygon smooth or simply polygon to smooth it. The result not perfect. If someone know to make perfect map from the classification result, please share these expenrience! @rahmansubeam. I dont use Illustrator software. . I use Arcgis, Mapinfo to make Map.
