Rebecca Remember to use SnapRaster (=raster being contoured) as well when setting the extent as ContourList will resample the raster before contouring if the extent does not fall exactly on the origin of a cell. -Steve ... View more

Ben Please zip the input data if you can and email it to me ([email protected]). Also, what cell size are you using, what field are you interpolating on and are you setting any Environment parameters? Any idea if any Service packs were applied to the 9.3 version? -Steve ... View more

The crux of this problem is the conversion of the feature class to raster. As Dan pointed out. The Zonal tools will internally convert the features to raster using the FeatureToRaster tool, which actually calls the PolygonToRaster tool using the CELL_CENTER option. However, you could do the conversion yourself and choose to rather use the MAX_AREA option or you could specify a PRIORITY field. -Steve ... View more

Jessica Run the tool in foreground mode, i.e. Geoprocessing->Geoprocessing Options and uncheck the Background Processing Enable button. -Steve ... View more

What is the spatial extent of the data? The data appears to be in a geographic coordinate system, have you changed the output coordinates in the environment to a projected coordinate system? What is the elevation range? A small contour interval does not mean that you’ll necessarily get accurate contours. ☺ Also, for testing purposes, zoom to a smaller extent and in the environment set the processing extent to display and then run the Contour tool. -Steve ...

Based on you reply I would suggest that you put in a call to Esri Support. -Steve ... View more

The ContourList tool works with all supported raster formats. What version of ArcGIS are you using? What is the min/max of the raster? what z values are you contouring? Is it a big mosaic raster, if not, use CopyRaster and copy it to an Esri grid or .tif -Steve ... View more

In 10.2 we introduced a Python class GeostatisticalDatasets which will make it easier for you to match up the datasets. ga_layer = r"c:\temp\kriging.lyr" geo_datasets = arcpy.GeostatisticalDatasets(ga_layer) print geo_datasets >>dataset1='c:\temp\myfc.shp' dataset1Field='ELEVATION' -Steve ...

You could simply use the Resample (in Data Management) tool and choose bilinear interpolation. ... View more

What interpolation are you trying to do? Fill in voids or resample it to a finer resolution? ... View more
