We deployed several surveys on the 2.8 version of Survey123 which have calculations in the repeats.  This worked fine until I just updated to a newer version of Survey123.  Now the calculations do not work in the repeats.  Simple sample attached.  Any ideas? ... View more

We have been testing a high accuracy GNSS GPS with Collector (Aurora and 18.0.1) in a development environment and utilizing ArcGIS online as our Portal.  As we plan to move to the production environment questions have arose pertaining to minimizing data translations to maintain accuracy.  The GPS utilizes and outputs in  the GCS NAD 1983 2011 coordinate system from our State VRS network.  We have been translating this to WGS 1984 Web Mercator Auxiliary Sphere for use with ArcGIS Online and its related basemaps.  Our production system also utilizes the GCS NAD 1983 2011 coordinate system, specifically the NAD 1983(2011) State Plane and no translations are needed between the GPS and production servers; however, we plan on continuing to utilize ArcGIS online as our Portal for collector.  What is the best or recommend approach to maintain the collected coordinate data accuracy? We are considering: 1) generating our own basemaps on our local servers using the GCS NAD 1983 2011 coordinate system and pushing these up to ArcGIS online and sideloading them directly onto our Collector systems (when/if they will fit).  This would save on credits used for building the tiles but we will still be utilizing credits for storage.  Subsequently, we would publish our features utilizing the same coordinate system. This is currently our preferred approach as there would not be any translations required. 2) continue with the current approach of collecting GPS data using GCS NAD 1983 2011, translating to WGS 1984 Web Mercator Auxiliary Sphere on ArcGIS Online and then translating back to the NAD 1983(2011) State Plane we utilize internally.  We have noted a definite shift in the data collected utilizing this method when compared to data collected by our surveyor utilizing a total station or survey grade GPS on our own local network.  I have experimented with different translations but the WGS_1984_(ITRF08) to NAD_1983_2011 we are utilizing provides the best match.   3) a question for the ESRI team is it possible to utilize the ArcGIS online basemaps without Collector automatically using the WGS 1984 Web Mercator.  We did try and publish a feature using the GCS NAD 1983 2011 coordinate system but the Maps/Collector automatically adopts the basemap coordinate system.  We were also not positive on how the point data was being handled with a mixed coordinate system and most likely introducing further translations and potential errors.   It is ironic that a few years ago GIS data that was accurate to a couple of meters we considered fantastic and now we are looking at a target accuracy of 10cm and achieving an actual accuracy of less then 2cm ...

We are in the process of setting up collector to be utilized with a high accuracy GNSS GPS.  Our GPS utilizes the GCS NAD 1983 2011 coordinate system and we are currently performing a transformation to WGS 1984 Web Mercator Auxiliary Sphere for use with ArcGIS Online in Collector.  When the GNSS metadata is captured in collector are the latitude, longitude and altitude values from the non-transformed GNSS coordinate system or transformed values in the WGS WEB Mercator?   We have concerns about our data undergoing multiple transformations and introducing potential errors between the GPS, Collector, ArcGIS Online and eventually on our data stores.  If the metadata values are the original GNSS data we will simple utilize that information once the data is back on our local systems for processing. ...

I have a simple survey form with a repeat section.  When I set the repeat_count to a previous integer value input on the form ${counter} the select_one dropdowns display strike-out text once a value is selected.  If I use a fixed value for the repeat_count or leave it blank and use the Add/Delete functionality of the repeat the dropdows are fine.  I also tried setting using string(${counter}) and int(${counter}) for the repeat_count with the same result. The appearance of the select_one filed are set to minimal. Any input? repeat_count set to ${counter} an integer field value, strikeout text displayed in dropdowns: repeat_count set to fixed value of 2, normal text displayed in dropdown: I attached a sample file that demonstrates the issue.  I did find a few workarounds; 1) place a non-zero value in for the default on the ${counter}, 2) turn off required on the select_one and 3) use a fixed value or do not set the value for the repeat_count. ...
