Hi! I've just found a solution for a small (sometimes big) problem. I've created a big Ecw dataset. The size was many gigabyte, and the working time was around a half day. And i've wanted open the file in arcgis > dropped an error "Invalid raster dataset". Many times i restarted the the progress, created a new file. Okay, shortly the solution: don't use any chars, only numbers and characters from english alphabet. I used é, á, ú, ű chars, and when i've changed it to e, a, u, the Arcgis opened the file... I hope this will help for anyone:) olla

GWR Software Version 4.0 - 32bit and 64bit - Freeware This version of GWR is a new release of an application software tool for modelling varying relationships among variables by calibrating Geographically Weighted Regression (GWR) and Geographically Weighted Generalised Linear Models (GWGLM) with their semiparametric variants. The GWR4 software was developed and programmed by Professor Tomoki Nakaya of the Department of Geography, Ritsumeikan University, Kyoto, Japan. Many Thanks to Dr. Paul Lewis (GWR website maintenance), who patiently responded to my request. Any further question would be responded by GWR developers and GWR/Geo-Statistics experts at: http://gwr.nuim.ie/ Download: 4shared: http://www.4shared.com/rar/v-ddSpNE/GWR4_0.html MediaFire: http://www.mediafire.com/?v81hrh0j5lq3ef4 for more information about GWR concept: What is GWR? : http://gwr.nuim.ie/?q=node/3 GWR in ArcGIS: http://gwr.nuim.ie/?q=node/9

hi friends, here is the the code for spatial cross-correlation (Matlab) there are 2 surfaces we are going to compare or find correlations maybe you should convert them to raster first A = imread ('...'/firstraster.jpg'); B = imread ('.../secondraster.jpg'); Result = normxcorr2(B,A); size if B should be equal or lesser than size of A the result is an arrey of correlation as kernel ( B moves across the Image A ) max(max(Result)) % the max xross corr found by kernel imshow (Result) % xross surface
