Dana I'd change outLayer = str(zField) + ".shp" to outLayer = str(zField) because it is an in-memory geostatistical layer. Secondly, outRaster  is empty which means that you opted only to output a ga layer and therefore you don't need to specify a cell size as it only pertain to the output raster. -Steve ... View more

outLayer is a geostatistical layer (in memory). To persist it you'll use SaveToLayerFile, or in the script convert it to contours using GALayerToContour or specify an output raster in the call to EBK. -Steve ... View more

to create a mask polygon I'd follow these steps Basic Digitization in ArcGIS - YouTube   and where they get the spatial reference from the image you'd get it from your input points, if they have a spatial reference else skip that step. -Steve ... View more

On the Environment Settings dialog you can specify a raster or feature mask. ... View more

Fabio That is great. If this raster has a value of 1 and NoData elsewhere you can use the Times tool rather than ExtractByMask until you change to ArcGIS 10.6. -Steve ... View more

Only way that (I can think of) to do that is to add a short field to the table and then use CalculateField to update the values. To get this newly created field as the primary value field you’ll need to use the Lookup<http://desktop.arcgis.com/en/arcmap/10.3/tools/spatial-analyst-toolbox/lookup.htm> tool. ... View more

Fabio To set the cellsize for PolygonToRaster you can use the environment or via the Cellsize parameter on the tool, drag the rasterlayer from the table of content into the control or browse to the raster dataset on disk. ... View more

Are the values in your input raster in the 4 bit range? ... View more

Fabio This might be related to a bug that got fixed post 10.5. Please try the following; PolygonToRaster using your shapefile as input (use any field), however in the Environment settings , set the Processing extent and cell size equal to this problematic output raster that you created using ExtractByMask. Does the "block" of data appear in the northeast? Not sure if this'll work but it is worth a try. When running ExtractByMask (or PolygonToRaster) in the Environment settings change Tile Size (Raster Storage) to 1024 by 1024 -Steve ... View more

No, the new output raster can be any format that supports short int. You decide on the Pixel type. ... View more

what is your workspace set to, default fGDB or not? what output raster format are you using (.img or .tif of fGDB or ...)? how columns and rows does the output raster have (right click -> Properties)? what version of ArcGIS? ... View more

Helga Good. Before you do kriging please goto to the DataManagement toolbox->Features and use CopyFeatures and copy this XY data you've just added to a feature class. Then use this feature class in kriging. ... View more

Helga No problem, we'll do it step for step. The data from the spreadsheet, how did you get into into ArcMap? and please send a screenshot of the spreadsheet so that we can see some of the rows and what the columns are named. -Steve ... View more
