Have you tried uncheckking the "Simplify polygons" option ? Thanks Steve ... View more

The text file must contain 700 * 1300 legit values from the 6th row onwards. It'll then use the first 700 for the northern most part of the raster and so on with the very southern most part coming from the very last 700 values. It appears that you have non numeric values somewhere after the 6th row or you don't have 700*1300 values. Steve ... View more

It is not the correct format, please see the help for the correct format. You can't have strings and semicolons. I.e     NCOLS 3     NROWS 2     XLLCORNER 378922     YLLCORNER 4072345     CELLSIZE 30     43 2 45     35 45 65 Steve ... View more

Chris What version of ArcGIS are you using? Are you only using contour input? What is the average spacing between contour lines? What cell size are you using? Have you tried using stream/rivers as input? How many iterations are you doing? Are your data in a projected coordinate system? Thanks Steve ... View more

What is the size (on disk) of the: *.shp and *.dbf files? If these sizes are not close to 2.1GB, then it might be related to NIM078850 which we're currently looking into. Steve ... View more

[ATTACH=CONFIG]15309[/ATTACH] 3 random rasters, each with integer values between 1 and 4. The COMBINE output has a table that lists all the combinations, viz., There are 1001 occurrences where raster1=1, raster2=1 and raster3=3. You can add a field and sum these 3 columns into it. There may be many other solutions, this is the first one that came to mind. Steve ... View more

How many features are there in the 10th feature class?, viz., in F:\PC-LAB_abr12\Shapefiles\SAD_69_Polyconic\LitoralBrasil_PCS.gdb\Litoral_Brasil_1\Lut_ana_1 Risk_rank you can use GetCount or open the attribute table. What happens if you run PolygonToRaster GP tool using this feature class ? Thanks Steve ... View more

Jamal It is often better to cite a reference rather than copy from it. This will give you more insight into the inner workings and assumptions around these equations. Which is what we have done for IDW and Kernel Density. Steve ... View more

Al These (explore data>semi variogram) are part of the ESDA tools. The point cloud will consist roughly of 4000*4000/2 points (8 million points). I'll be too dense to get any meaningful info from. You did see the warning message that came up when you tried to process the 4000 points? I would suggest that you rather take a subset of your data (use the SubsetFeatures tool). I would suggest no more that 500 points. The 4000 points will be fine to use when doing kriging though. Steve ... View more
