How do I measure distance around an object? Here is my situation. I am trying to measure distance between points across an area of water. The water area is broken by swamps, islands, and other pieces of land. I cannot measure Euclidean (straight line) distance between points because I need to take land into account in this scenario. I want to do something like I've illustrated below. I have drawn a line between two points across the water, moving through islands. The screen shot is just an example but you get the idea. I have a feature class containing the points and a feature class of the water area.  Least-Cost path solutions seem like they might be a solution. Two problems with this are... a lot of examples rely on a DEM, which I don't have because sea level elevation is 0. I've tried converting my water polygon to a raster object and using this as my surface raster, but have not gotten the desired result. I think I don't understand the least-cost path tool in ArcGIS Pro I've read the docs for this tool. A couple things I fundamentally don't understand are... -There is an input field for the destination data, but how about the starting point?  How does this know what to measure between?  (I have many points) -What is the input cost backlink raster?  Of course, the cost path tool may not be what I need after all. Can anyone offer input?  ... View more

Hi- I'm struggling here. My question is 2 parts: I have a table (attached to this post) with usage data from a building on a college campus. There are 4 floors in the building. Each floor is broken into zones, where headcounts are taken at various times on various days. My first problem- I have all my data in a table and I have layer files for the 4 floors in the building with their corresponding zones (zone 1, zone 2, etc). It seems I should create a relation between this table and each floor layer, right? Second problem- Now, I'm trying to figure out a workflow to migrate this into ArcGIS online. Ideally the WebApp would do the following: Allow users, via some kind of drop down or radio button menu, to select a floor, a date, a time, and another variable to display. So for example: User chooses floor 1, October 19th, 10am, total headcount. I'm not looking for step by step instructions but some guidance would be much appreciated.   Thank you, Erich ... View more

Hi- I've got a table and a layer. The layer is 5 zones of the first floor of a building labeled zone1, zone2, etc.  The table has headcount data for # of people in those zones at different dates and times.   If possible I want to join this table to my layer in order to eliminate steps for end users. I'm hoping to use this in an ArcGIS Online Web App to spare them multiple steps of querying, joining, etc.   It seems I should be able to join the table and layer in a one-to-many join but I have not had success. Any help is appreciated. -Erich ... View more
