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.
