Land cover classification and Change detection technique
By Daniela_06,
Hello,
I need to do a land cover classification of satellite images from diff years 86,91,98,02,12 from different providers like ASTER and LANDSAT and I have several questions regarding some issues I am presenting. Hope someone can help me.
1. Do the Landsat images need to be ortho rectified, they are L1T images TM and ETM+ if so, can I use the ASTER DEM of 2011 that I have to ortho rectify all of them? no matter the year? An if the DEM is in a different resolution that the 30m how should I d
PALSAR data
By windstalker,
Hi all,
I completely new to GIS/remote sensing, so first of all I'm sorry if I asked a silly/stupid questions.
I have a PALSAR data
Uploaded with ImageShack.us
I dont know how to start processing it,
so far I used ERDAS to import the LED-*********.1__A file to .img file, and open it in ArcGIS.
Is it a correct way to process PALSAR data ?
and if I'm not mistaken, we can get DEM from PALSAR by using two images. Is that correct ?
Thank you,

Project ideas needed
By Pleyadess,
Hello everyone, I am about to start my final dissertation, unfortunately I only got the DEM of a portion of the seafloor as data. I need to find out a project that could be done in ArcGIS just by using this data. I don't know what else I could do with this seafloor DEM apart from creating slope and aspect surfaces. Is there anything more complicated or more extensive so that I could call it project?.
Thanks.
Spatial analysis, regression and correlation between 2 rasters
By Arhanghelul,
Hello !
I would like to make some spatial analysis regarding regressions and correlation coeficients between 2 rasters.
I have 2 rasters:
Land use/ Land cover extracted from aerial images
Land Surface Temperature (LST) derived from LANDSAT thermal band.
Both raster images are co-registered, in the same projection, having a RMSE error <=0.5 m.
Now I would like to see if there are some spatial correlations between these 2 images.
What software can I use for this task ?
I know that t
