Are there any adverse effects of having cell sizes as low as possible? - processing time - size of output raster - at some point you are not gaining anymore information You have to think about the scale at which you phenomena changes. Say you decide on 30 meters, that means that each 30x30 meter area has the same value. If you have access to Geostatistical Analyst you can perform cross validation to decide which interpolator produces the best results.

Mike As far as exact interpolation, please reference the following image. 2 cells of a raster, white equals the cell center and red is the sample location. Predictions are made at the cell center and that value is assigned to the whole cell. When predicting the value for the upper cell, 1395 will carry the most weight and therefore the cell's value will not be equal to 1395. However, 3199 falls exactly at the center of the cell and therefore that cell's predicted value will be equal to 3199. The smaller the cell size the closer the predicted cell value will be to that of the sample point Regards -Steve

Charles Are you running it in background or foreground? Please post a screen shot of the dialog before you hit run. Thanks -Steve

The station's coordinates are in lat, long. Does this mean that they are in degrees decimal?

- you are sending the output to an Esri grid named "D:/Documents/PhD/GIS/Odhran", correct? - specify the full path to mygrid.asc - these ASCII files are actually raster datasets and you could use CopyRaster ipo ASCIIToRaster

Background geoprocessing is by default = 32 bit, to get the 64 bit version requires an additional install. Felipe, - from the UI it succeeds in background and in foreground, correct? - try sending the output raster to Esri grid or .tif

When it succeeds, what is the size of the output raster? (Right click on the raster layer and have a look at the number of columns and rows)? Did you install Background 64 bit? Does IDW succeed in foreground? Are you running the geoprocessing tool from the UI or are you running it in the Python window?

The RasterToPolygon tool's input must be integer. You could multiply the slope raster, by say 1000, and convert it to integer.

Please navigate to the folder where the shapefile is stored and zip all the files making up the shapefile and email it to me at slynch@esri.com I suspect that you have a corrupt shapefile.

The only interpolator that we have to use with global data is EBK in Geostatistical Analyst. It uses chordal distances. A point to keep in mind with most interpolation techniques is that the weight decreases with distance.

Karl Which kriging method did you use? Are you using Spatial or Geostatistical Analyst? Can you provide an image of the contour lines? Thanks -Steve
