When creating service areas and generating drive time areas in ArcGIS Pro (using the ArcGIS Online routing service), there's a table in the online documentation that indicates the "Speed Data Source" for each country.  One of the values is "Fixed Speeds," defined in the Arc Online documentation as having "Comprehensive street data with static travel times derived from historical average speeds for automobiles is available. Analysis results won't vary by changing the time of day."  Does this mean that for countries with Fixed Speeds indicated, that all streets/roads in the entire country are categorized the same? That is, there aren't fast intercity roads and slow local roads, fast paved roads, and slow unpaved ones, etc?   Just all are the same?  The alternative would maybe be if the static speeds are assigned to each road; these don't change by time of day, but maybe different roads do have different values. But I don't see that this degree of granularity is available within the service area layer. The country of interest is Tanzania. ... View more

I'm at a university with an Esri campus site license.  The students use Pro, Desktop, and/or AGOL.  A student had a question regarding sharing a custom tool as a web tool. He used Modelbuilder in ArcGIS Pro to create a custom tool.  He wants to incorporate this tool into a Web App in ArcGIS Online that he wants to share with the world if possible, or, if not, at least share with a group or the organization. He has access to ArcGIS Online, which he's familiar with, but not to a Portal in ArcGIS Enterprise.  We don't have an instance of Enterprise/Server/Portal that is generally available to students (just used by some profs for coursework in some Env Sci classes), and I'm not personally familiar with that environment (hence this question). I work in the library and provide general support for students with GIS questions. He attempted to publish this web tool to AGOL, but gets the error "Cannot publish web tool to ArcGIS Online." As far as I know, such a web tool, in general, can't be published to AGOL; there doesn't seem to be any permission that relates to web tools, and he has all non-administrative permissions.  The questions are: are we missing something about AGOL and web tools? Without using Enterprise/Server/Portal, is there any way, such as a workaround, to run such a custom tool in AGOL? The student tells me, "Our proposed workarounds right now are to share the ArcGIS folders with users (which would be clunky but would work) and to create an RShiny app that would have the tools behind the scenes." I can get more details if you need. Thanks for any insights. --Mark Thomas, Duke University LIbraries ... View more

Background: We're a university with an Esri campus site license and use Enterprise logins. We have a demand occasionally from users who need to post an interactive map online (e.g., an Esri Storymap), but it’s the result of a research project that was a group effort, more associated with a Duke program rather than an individual. The individuals affiliated with that program may come and go, but the hope is that their final product (interactive map) can stay with the program. There might be a need for other researchers in the future to update underlying data used in the map. This has been a hassle in the past to migrate content from one host to another, and involves administrative overhead. Question: Is there any way using Esri’s cloud (not a locally maintained instance of Arc Server) to have such an account to host services that isn’t associated with an individual Arc Online account attached to an individua? An individual may leave Duke, so the services on that person’s account would go away unless they arrange for migration to another person’s account before leaving. Basically, having content reside not in an individual’s account, but in some sort of department/program account? Since the accounts are associated with Duke NetID’s, they don’t seem to readily lend themselves to this sort of set-up. There are AGOL Groups, but these have a real-person owner in charge. I wondered if anyone knows of a way to work around this reliance on an individual when dealing with groups? If this isn’t something that Esri makes possible, then departmental/program accounts are something that should be developed for AGOL organizational site licenses if there’s any way to work it out (there would necessarily need to be an official real person owner at any given time, but that person could come and go and the hosted data would stay with the departmental account). Thanks for any insight on this. --Mark ... View more
