When teaching remote sensing or how to classify rasters, I find it is vital that students have access to the histogram of the data either in the dataset or in the current view (both would be helpful). Even in the help for Pro's Stretch Function, a histogram makes it clear how or why a percent clip routine is useful. Stretch function—ArcGIS Pro | ArcGIS Desktop  However, it is only possible to see histograms of integer continuous data, albeit poorly, in the symbology pane, but not for floating point or imagery data.  Thus, in my GIS and Remote Sensing class that now uses Pro, I have to apologize for Pro's lack of functionality and display histograms from other products, for example, showing atmospheric contributions to radiance distributions from ERMapper that we used years ago. from http://geology.wlu.edu/harbor/geol260/lecture_notes/Notes_rs_haze.html  Please put a window in the symbology pane (or if not that, at least make a geoprocessing tool or function) that displays a histogram for any raster (continuous, fp, or categorical), single band image (tif, ers, grid), or multiband image (tif, grid, ers, etc).  Optimally, it will have a DRA button that can be turned on such that when the focus changes, the histogram will adjust.

As a preliminary tool in my work, I have been using the "create watersheds" under the raster analysis portal (from the ArcGIS portal) in ArcGIS Pro 1.x. I just switched to ArcGIS Pro 2.0, and hence we switched the license server to 10.5.1.  However, now these tools are greyed out with a warning saying these tools are disabled because I have to be connected to a portal with raster analysis tools.  I have tried making my active portal both www.arcgis.com and mycollege.maps.argis.com, and neither works. We have an educational license and I am an administrator in the organization, and have all the administrative level privileges.  We do not have our own portal set up for image or data service.  Under "roles" in our organization, we do not have the option to turn on "Raster Analysis" under "Content and Analysis" as suggested on this page. http://server.arcgis.com/en/portal/latest/use/roles.htm, but I don't think we're running a portal here at our organization (just students and faculty using ArcGIS Pro and Desktop independently). Can I get these helpful portal tools back? Thanks ... View more

I frequently create models to delineate and export stream rasters from DEM input.  However, on large basins, computing basin accumulation (thanks to ESRI, on just one core) takes hours and has to be done twice, once for the accumulation step and once again in the watershed command.  The latter neither uses the already present accumulation nor does it save it such that I wouldn't have to compute it separately.  Any way around this? And to the watershed command, let me add stream link, basin and stream link.  Each recalculates flow accumulation and doesn't save it.  For clarity, I am using ArcGIS Pro 2.0 in model builder. ...

Using ArcGIS Pro 1.3.1 and doing a tutorial from Getting to Know ArcGIS Pro Chapter 4, some students are able to click a "map notes" template and add them, and others are not.  When some of them click one of the Map Notes icons, nothing happens, others get the feature layers in the contents and can create notes. The ArcMon suggest that a process was called, but nothing happens.  New to ArcGIS Pro this year.  Don't know if/where event logs are kept. What is different about individual maps that would cause this error? What requirements are we missing?  Is there a tool /python command to run that would give an error message to look at?  Playing stump the professor; they won. ... View more

A recently installed 10.2 version doesn't produce geoprocessing history in new files or files created from 9.3-created files.  I need to have this option for a 25 student lab so that I can follow their process.  In the Customize/options tab, I have tried it with the "update" option check and unchecked, and tried it with several metadata types other than Item Description to no avail. Is 10.2 different from 10.1 in the automatic inclusion of the history in the metadata ? (it wipes out previously existing geoprocessing history as well) UPDATE (13/12/18):  Tried editing the metadata for newly-created Raster dataset and a feature class in a newly created file geodatabase.  Neither has any Geoprocessing information from the tools used to create them.  If I have had 9.3 installed on my laptop or on the class lab machines, do I need to find and erase all the "ESRI" AppData?  Could this be a source of the problem?
