Survey123: Z-values?

[pjdohertygis]

From MO-TF1: More of a general mapping "Z" question that I am researching to better support mapping for large building/structure search vertically. How has v8_WAS data been looking when teams have been in GPS deprived areas like as they work within voids in the garage? We are only capturing XY if I recall. Maybe we need v9_WAS to capture X Y and Z information from the GPS and add a Z-level field that users can enter "floor/level" info so we can extrude the data in 3d to show heights/level of their search progress. Lots of work has been done on this on the NENA e911 side - https://www.fcc.gov/public-safety-and-homeland-security/policy-and-licensing-division/911-services/general/location-accuracy-indoor-benchmarks

I suspect that we would want two approaches.

Calculated Z - whatever we can get from the device and GPS. Bad Elf's or other devices may help with this. Derived Z - whatever information we can get from the person entering. Floor number?

For when building that is still standing or to some extend collapsed but still "in levels", third approach could pre-load local or US National Address Data with vertical aware address point data to be assignments for searching. NENA and US NAD has a floor field that if populated could give us the "heights". Bigger issue is positional accuracy when a team is inside with no GPS signal and the ESRI map apps will not allow mapping because of the minimum positional accuracy required/setting.

@pjdohertygis If the feature layer as Z enabled in the SHAPE field, Survey123, QuickCapture and Field Maps should automatically record the Z value. If you are creating a new layer with Survey123, check this article: https://community.esri.com/t5/arcgis-survey123-blog/working-with-z-values-in-survey123/ba-p/895011

It looks like our current v8 waypoint layer does not have Z enabled so we cannot easily implement the Shape approach.

Let's continue the discussion on this within the Cadre.
