Not everyone is happy with "approximate". If a field user has a high accuracy external GPS receiver, the option to collect accurate data should be an option in Field Maps and one should not have to post process ellipsoidal heights to get orthometric heights. The fact that Field Maps does not understand Geoid and Orthometric Height is a big problem in my eyes.
JMAP ALTITUDE GEOMETRY SOFTWARE
I am not a fan of the work arounds when I know there is other software out there that can do what I need. I had already reviewed the links you included above, including the work arounds. This would be a great idea and I would certainly upvote it!Įdit - It appears that there is already an idea in for this. I still use Trimble TSC2's for field work and when setting up the job the geoid model to be used must be selected so I know exactly where you are coming from.
JMAP ALTITUDE GEOMETRY FULL
TerraSync, being a Trimble product and an extension of their survey history, probably has full knowledge of the various geoid models out there and can apply them to field measurements. In the US the NGS handles is the caretake of the US data with others responsible for their respective jurisdictions. Have you checked out the requirements for high accuracy FieldMaps use? įrom what I am seeing, FieldMaps only uses the GPS ellipsoid height and has no knowledge of the geoid model concept, or the ability to apply it, to get to Orthometric height so must be handled in post collection processing and are very specific to the area you are working in. Granted TerraSync is now a software dinosaur, but has great functions and options for collection. From a user who has been using Trimble TerraSync, Field Maps does not have near the functionality of TerraSync. I would really like to use esri for a field collection app, but may need to go to another companies app. I have other issues I could list, but I have found work arounds for those. Basemaps in ArcMap can be projected on the fly, why not in Field Maps? For a new field collection app, Field Maps seems like it is not ready for "Prime Time". I have attempted to create my own simple basemap in my desired projection and bring that into Field Maps, but have had no luck, FieldMaps still says the map and profile coordinate system do not match. I can create another one in my profile within Field Maps, but in order to use the the esri "canned basemaps that you must have your project set-up to WGS84. Additionally, I cannot get Field Maps to take a coordinate system other than WGS84, which I think would help me in recording orthometric height. I see it records Altitude as ellipsoidal height, but I do not want that, nor can I think of why anyone recording Z-value would want that over orthometric height. I am using an external GPS receiver and would like to record Z-values in NAVD1988(ft).
This should be an easy out of the box solution/option. I have seen some post and articles but the solutions are pages long.
JMAP ALTITUDE GEOMETRY HOW TO
Has anyone "cracked the code" on how to get the orthometric height attribute exported from a point feature collected in Field Maps? I have read articles high and low on this subject but cannot figure out a successful way to get this to work.
