I was able to republish my SD file by going to the hosted notebook server at https://notebooks.esri.com and running this updated ArcGIS API for Python code: from arcgis.gis import GIS sd_itemid = "a71a0a30cd0e4cde9d196f99e935a919" gis = GIS("https://www.arcgis.com", "YourAGOLUserName") #Find SD file, then update or add, then publish sd_item = gis.content.get(sd_itemid) #Parameters for editor tracking pub_params = {"editorTrackingInfo" : {"enableEditorTracking":'true', "preserveEditUsersAndTimestamps":'true'}} sd_item.publish(publish_parameters=pub_params, overwrite=True) ...

Also, when you measure your output axes, which is correct?  I am guessing the one from ArcGIS Pro/Desktop are, and the GeoEvent output is incorrect?  If so, does it seem like a unit conversion issue?  Here is the area of the geoevent code I would be looking at if you aren't already: defense-solutions-proofs-of-concept/EllipseProcessor.java at a257842326f73f5691e56ba623c865146534c84e · Esri/defense-sol…  ...

Hi Brian, Is your input really coming in as 3857 coordinates?  I would think lightning strike data would come in with Lat/Long?  What happens if you make your input WKID 4326? ... View more

Hi Becky! I am going to share with you a number of things I have learned about this when working with other people trying to do similar things.  Much of this information has come from other people within Esri. Regarding your question B above, I think having one service/mosaic that has all of the data in it can be very useful, instead of having many.  This would be why I might want to use the derived mosaic.  We often recommend making source mosaic datasets for homogeneous datasets, and then a derived one (using the table raster method) to combine them into a single source. You may find this useful if you haven't seen it: Derived mosaic datasets—Standard Workflow_Creating Mosaic Datasets | ArcGIS  1. Pyramids & statistics for Source Rasters   It is important to differentiate between the use of the mosaic datasets for dynamic & cached services.  In the case of cached services, there is relatively little benefit to pre-building the pyramids (except perhaps for a potentially tiny improvement in the actual caching process) since the cache itself acts as the equivalent of the pyramids.    However for dynamic services, building pyramids can improve response when zoomed in to the display scales that are larger than the display scales for displaying the mosaic dataset overviews.  This display range often extends from the source data resolution to about 10-20x the source resolution.  If performance and access to underlying radiometry is the goal then it may be prudent to build a few levels of pyramids.  Do recall however, that resampling of the digital numbers results in averaged values of the pixels when viewing and interrogating the pyramid layers.   For the purpose of ensuring availability of the pyramids (and to avoid accidental loss of access to pyramids that are stored external to the source rasters, I often recommend building the pyramids as internal to the source file.  In that way, the pyramids have no risk of being separated (pathwise) from the source rasters.  The penalty is slightly larger source raster files.   In terms of the statistics, it is always recommend that statistics be computed on the source rasters (again during ingest) and stored in the TIFF tags.  It is important to use a reasonable skip factor for rows and columns to make the statistics computation fast.  That is, it is not necessary to use each pixel in a file to achieve a representative mean and standard deviation for each file.  A sampling of 5-10% of the set of pixels is usually sufficient.  Thus, the skip factor can be computed by dividing the number of rows and columns in the file by 20 and using that as the skip factors.  For pre-stretched, pre-rectified, color-balanced 3x8=bit RGB content (like NAIP), having statistics will permit smoother rendering (via the selection of one of the stretch options) of the imagery especially where multiple years are in the collection.    For elevation data (32-bit float), it important to build the statistics to ensure that the rendering of the 32-bit data into an 8-bit stream properly reflects the range of values in the elevation data.  If not built, wide (or narrow) ranging data can appear all black.  It is important to compute the statistics for elevation data since this also establishes the max/min range for the data.   All of these steps can be completed during the ingest workflow. 2. There are two approaches to handling multiple spatial references for mosaic datasets. If the source data is in multiple spatial reference systems but a single spatial reference is the output of the service (i.e. Web Mercator), the it preferable to allow ArcGIS to define the required geodata transform that transforms the source SRS into the mosoac dataset SRS on ingest.  The derived mosaic dataset then does not need to impose another geodata transform on rendering.  IT can still however support definition queries or other functions.   If there are to be multiple services from a mosaic dataset in multiple SRS (i.e. WM, State Plane, UTM, …) then, as defined above, allow ArcGIS to define the appropriate geodata transform to each raster during the ingest into a source mosaic dataset (perhaps defined with a SRS of web Mercator).  Then define multiple derived mosaic datasets (one for each required output SRS and use these to publish the services.  ArcGIS will define the output geodata transform from the source to the derived mosaics.  If caching these services, make sure to define a custom cache tiling scheme file which represents to desired spatial reference. ...

Survey123 already supports setting the font tag in the app for the choices.  The web app needs to apply the tag as well, not just display the html as text.  The report templates won't help here. ... View more

Hi James, It would be great to be able to have the time spinner only show 0, or 15, or 30 or 45 as well.  Is there a way to do that? ... View more

Any plans to add the URL parameters to the web version of Survey123?  Something like this: https://survey123.arcgis.com/share/97d70799eee54483881ede07cf5c2c3c?field:[email protected] Or is it possible already and I am just doing something incorrectly? ... View more
