Is it possible to create radial flow maps with ArcGIS online? I have located an esri how to blog, but it's for Desktop. I found a video that used "Find Nearest" to connect countries to one map note point. Any thoughts? ... View more

Perhaps I'm missing something simple: just trying to use survey123 to capture information about salt marshes- using the survey123 palette of questions and asking users to walk around the marsh and "click" the shape of the marsh.  I thought I could add a field and "calculate geometry," but perhaps I need to be in ArcMAP or ArcGIS online PRO to do such a thing? Does Survey123 not support area as an attribute when the polygon is captured?  ... View more

Question : Maximum, how many ArcGIS Web-adapter can be installed on a single Machine?                    Use Case : Usually I installed two till dated   one for ArcGIS Server   (Mapping service)   one for Portal for ArcGIS                     So consider when I separated a Site for Analytics , one for Geo-processing and one more for Printing utility. So advise me should I installed separate Web-adapter  for Analytics, Geo-processing and Printing utility      Note : I'll federate all these into my portal for ArcGIS     Thanks Veer portal for acrgis  ‌#web adapter 10.7.1 ...

I'm a student at University of Massachusetts Amherst studying GIS Technology. This is my first semester in the GIS-T Masters program, and I'm studying at the new UMass Mt Ida campus in Newton, MA. I am currently the only student enrolled in the GIS-T program at this location, and one of a small handful of students considered as early settlers here. (note: as the instructional model for this campus is a flexible blend of synchronous tele-presence classroom instruction and/or self-paced asynchronous learning... the business model here is not nearly as dire as it might appear.) For me, these past months represented semester one, class one as a part-time student in the GIS-T program. My professional background is actually in marketing, having prior work experience in real estate development, public service utilities and local government.  While I've found the GIS technology (ESRI et al) itself to be quite interesting, my most profound educational moments have come from the realization that many of the "simplistic" models used in defining our planet, although widely held as "universal truths" by the general public; in actuality, really weren't quite exactly "true." For example, while most have now reached the conclusion that our world isn't flat... Earth also isn't round. Earth isn't a sphere, nor the shape of a grape, tomato, or anything else one might find within their supermarket's produce aisle. Additionally, that basketball size learning tool (typically referred to as "globe") which graced window-adjacent low bookcases in just about every classroom of my primary and secondary educational experiences, also isn't really an accurate representation of Earth. It's really just a map projection, most likely constructed to serve as constant reminder of how the USSR should be perceived as "big and powerful." (okay, I added that last part... purely personal conjecture) I also learned that gravity (at least little "g") on this planet doesn't happen at the constant rate learned during so many introductory Physics lectures. (and reinforced via the laboratory components of those courses) When applying prior knowledge that man's measurement of time, at least in the scientific sense, is actually a function of gravity... one reaches conclusion that time itself isn't constant at all locations on our planet. (ie gravitational time dilation) So... time isn't actually a constant... and that classroom globe isn't what Earth really looks like. (even the bumpy "deluxe topographical" version is far from accurate) At least for me, both were considered to be "full stop" moments of learning. When I commenced this course of study, I expected to gain a better understanding of the many business challenges of improving the accuracy of Uber pickups or perhaps gain some actionable tactics for the optimization of site selection processes for a coffee shop franchisee. But, much like the Earth itself, the knowledge I’ve gained here to date is much more complicated than the simplistic Scantron #2 pencil educational model I had been expecting. And much like the actual Earth, it is far more powerful. ...
