Dear ESRI team, for teaching purposes, I'd like to learn more about the following and would much appreciate if you could provide me with your wisdom: AGOL allows to upload .csv, zipped .shp, GeoJSON, KML and convert these into feature layer (hosted). 1) What is behind a feature layer (hosted)? Still the original file format? Or in every case converted into geojson or into any other interchangable format?   2) How are feature layer rendered in the browser? Through canvas? or WebGL? or...?   Kind regards Stefan ... View more

Hi, I am seeking help for implementing a particular AGOL dashboard task. I got temperature measurements over time (every 20 min over 5 days) simultaneously at multiple locations. I'd like to allow a web map user to choose a certain time and would like the Series Chart to be updated. However, I could not find any solution allowing such action-triggered update of the Series Field of the respective Series Chart. my data basically looks like this: Location ID time 1 time 2 time 3 time 4 ... time 165 1 22.25 °C 23.2 °C 20.11 °C 22.11 °C 21.25 °C 2 21.55 °C 20.51 °C 21.6 °C 22.43 °C 20.5 °C ... 22.85 °C 22.05 °C 22.99 °C 22.44 °C 21.8 °C 85 22.75 °C 21.33 °C 20.25 °C 22.32 °C 20.56 °C Any idea how to solve that? thanks Stefan ...

Hi, I am currently trying to compute car-travel-distances (in km) from a given set of about 50000 point-pairs (origin-destination). I do have the points and the road lines as shapefiles. I couldn't find yet a smooth automatic solution using ArcGIS NA.  Does anyone have similar experience? Can anyone help? Thanks Stefan ... View more

Hi, I am currently applying zonal statistics on raster images (showing temperature values). I run the Zonal Histogram, which does create a table but not with the frequencies of my raster values, only stretched to the 8-bits image range : 1-256 Is there any way to create a nice histogram for raster values inside Arcmap? cheers Stefan ...
