@snowrad what version you are using? How large is the area you are trying to calculate? If it is a large area can you test a smaller one? For example clip out an area or you can an environment extent to a smaller (test) area? IE: Zoom in to an area where you have points and set the environment extent = "same as display". Are you able to .zip and share your data ?

This seems suspect as the tool validation should enforce sum of influence to equal 100. The large value you are showing are you saying are automatically being generated by the tool on validation? Does this work for you with a different set of raster layers? Does this happen only with these data? What if you have 2 or 4 inputs (not 10). If your problem persist I would suggest to open an issue with Technical Support and provide them with your data and reproducible steps to assist you better. As a work around if your data are already classed into equal categories you could try the Weighted Sum tool.

Additionally you could use the Spatial Analyst tool Extract By Mask.

Yes you are correct in your understanding. By default the "best" would be the highest resolution (smallest pixel size) for your area of interest. For an analysis tool such as CopyRaster (or Extract) the output result would be values that pertain to the best available data (sampled at the smallest resolution) for your AOI, which could be a mix of data sources if you features or extent cover a wide area. Did you look at the following coverage map? The coverage and extents of various datasets comprising this service in an interactive map, see Elevation Coverage Map. As to the error, not sure what the you are running into. Again make sure to look at environments and that you are not running into a service request limit (the service layer is restricted to a 5,000 x 5,000 pixel limit in a single request). If you have a particular reproducible case or details you can contact technical support or share your issue and error messages and we can go from there. Good luck.

@Anonymous User If I understand your question correctly... A terrain service could be a cached service or image service referencing to mosaic dataset depending on which endpoint you are looking at. For the ESRI terrain service (https://www.arcgis.com/home/item.html?id=58a541efc59545e6b7137f961d7de883 ) see the notes on datasource and mosaic method. By default for the mosaic dataset , it will give you the best data available on the AOI otherwise if you can make a query to ask for SRTM/NED specifically.

Always a good idea think about analysis environments in a workflow. 🙂 It would be important to manage the extent to reduce the size (the number of rows and columns) to process the image, which may affect performance. Also, to avoid in some cases, processing the entire extent of a large image service.

As a general rule Image Services are supported as input directly to Spatial Analyst GP tools in Pro. If you add the IS as a layer you should be able to use it in the tool. In python you will need to use the MakeImageServiceLayer tool to create a layer, then use the result as input to Extract Values to Points. Note: Be aware of the extent when creating the ISLayer (use template parameter) or set accordingly when running Extract tools. It would be important to manage the extent to reduce the size (the number of rows and columns) to process the image, which may affect performance. Also, to avoid in some cases, processing the entire extent of a large image service. For example, ISlyr = arcpy.MakeImageServerLayer_management(inRasterIS, "outISlyr", inPointFeatures) arcpy.sa.ExtractValuesToPoints(inPointFeatures, ISlyr, outPointFeatures)

Glad you got it working and the new output definitely looks like what you would expect. You are correct about the internal conversion so bypassing that seems to produce the correct result which points to the feature class you used as input. I wasn't able to reproduce it on my side but if you can share the input source features we can test it on our side. Kind regards. Thank you. Good luck. -Ryan

Hi Alberto, what version are you using? Note: If ArcGIS Pro you can use the Distance Accumulation tool which is the new functional tool for calculating distance. However the output does seem suspect but I can't tell from the image. What are the input source data features? Are these the recreation Points? Can you share the data?

Hi @Sara_ Trying to understand your issue better, What version of desktop are you working with? Is your mask a raster or feature area? Perhaps you are able to share you model and data with me and I can try to reproduce on my end? (attach to this thread?) Suggested to try and troubleshoot. 1) Run extractbymask stand alone (the case that works for you). Create a new model and drag the result from GP Result window into the model. Does this work? If so something in your model is different. 2) Note, as an aside, the IDW does support the environment Mask setting which might eliminate the need to use ExtractByMask if you are only trying to clip all IDW outputs to the same mask area?

Hi @ShirleyYueLi (coming in late.. better late than never?) Just wanted to add for future reference. You are correct in your interpretation of the number of bands and the hours of sunlight. This can be represented by the Sun Map Calculation . You can run this using the Solar Radiation Graphics tool. In terms of the specific hours... this is dependent on your location (latitude) and day. The sunmap sectors are calculated based on the time configuration, in your case one full day from sunrise to sunset (available light), where each sector is based on the interval specified for your time period. Unfortunately, the specific hour of each sector is not specified as an attribute in the result. Good luck! example sunmap

If you have a unique identifier to relate the two features (tables) you can use the Join Field gp tool.

Hi Simona, were you able to run the tool successfully? What was the solution? Was it only after projecting the inputs to common projection? 3900 points should process immediately, regardless of the size of the raster. Just a note for future, a good spot for questions related to Spatial Analyst tools directly can be asked in the Spatial Analyst Community. We monitor all but you may by chance get a quicker response.

Excellent thank you. The message you reported was returned in error and should have been the intended message ""Workspace or data source is read only". This will be resolved for next release of ArcGIS Pro 3.0.

‎11-19-2021

More info is required however I assume you are using a polygon mask to "cookie cut" the input raster? As noted Spatial Analyst tools and functions internally resample data to square cells. If this is more for display purposes and not part of a larger analysis workflow that uses Spatial Analyst tools you can use the Clip Raster (Data Management) tool and specify the Use Input Features for Clipping Geometry optional parameter .
