I don't know anything about trying to do this, but I want to learn how to, if it's possible. I work at a water plant and our telemetry uploads current operational information to a web page in a table format. We access that mainly on our smart phones to monitor our system when when we are not in the plant.  What I would like to do is pull information from this page, and use it within Operations Dashboard.  I can access data from the above page using a web page JSON requests. For example, https://xxxxxxxxxx.scadaweb.net:4443/JSON/STATION.php?addr=SH returns the following: { "StationName": "HSP & SCALES", "StationAddress": "SH", "StationStatus": 82, "TimeHour": 14, "TimeMinute": 10, "TimeSecond": 44, "AnalogInputs": [8.6,150,91.1,150,489.3,1000,170.4,364.6,0,109.4,177.4,0,0,0,0,0], "DiscreteInputs": [1,0,1,0,0,0,0,0,0,0,0,0,0,0,0,0], "ExpansionInputs": [0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0], "FlowRates": [331,0,0,0,0,0,0,0], "FlowTotals": [52578000,0,0,0,0,0,0,0], "OutputStatusWords": [38,4160,38,4192,0,0,0,0,0,0,0,0,0,0,0,0], "PCHOAS": [2,0,2,2,0,0,0,0,0,0,0,0,0,0,0,0], "AnalogOutputs": [0,0,0,0,0,0,0,0]} Is it possible to enter in a JSON request that would only pull the 331, which represents 331 gallons per minute? For a lack of a better way to describe this, I see a simple table and wonder how can I pull cell "A9" (A9 is just example) and shove it into a field that is contained in a layer on ArcGIS Online, which I can then use in Operations Dashboard. This sounds to simplistic, but is it possible to insert a URL into a field in a published feature layer, have it store that value from the table,  and then assign an "refresh interval" to update that value? I'm not trying to circumvent Arc Server, but we could never justify purchasing it just to update layers or to have me experiment. I've taught myself to use ArcGIS Online and Arc Desktop, but you can tell this definitely is not my area of expertise. I would really like to do more with dashboards, but I need the data from our SCADA to develop operational related dashboards (flows and pressures). We only have 15 employees so we are a very small company, but serve 17,000 people water. ArcGIS Online has been very useful for our company and I'm just looking for other ways to expanded on it by developing more apps, but I really want to incorporate these dashboards. If anyone can point me in the right direction that would be very helpful. I think I should find a book on this stuff. I know what I'm asking is possibly not doable. Thank you, Travis ... View more

Has anyone used the "Drinking Water Advisory" solution? If I create a Boil Alert on the Drinking Water Alert Web map by drawing a polygon to represent a boil order, save it, and then try to share it, the alert polygon disappears. If I leave that  same web map and come back to it, the polygon also disappears, even if I save it. If I go to the Drinking Water Advisory Management map, it will show the polygon that I drew on the Alert map, but shows it as a past alert and not current. Anyone else have this problem, or is there something I'm missing? Also, is there a way to embed or share the map that only shows the polygon and nothing else like water mains and valves. I need those two layers to determine where to draw the polygon, but I don't necessarily need to show the public our infrastructure.  Thank you! Travis ... View more
