I am looking to collect data on an mid-size city's storm sewer system. This would include using the collector app to collect information at each structure including all pipe data, size, type, condition, and location. We need to collect not only horizontal positioning, but also the elevation at the flow line. Is there a way to collect elevation at this time? Thus far, my research has lead me to using metadata to get the altitude, but I need my elevation based on my local coordinate system.
