中規模都市の雨水下水道システムのデータを収集しようとしています。これには、Collector Appを使用して各構造物でパイプのデータ、サイズ、タイプ、状態、および位置を含む情報を収集することが含まれます。水平位置だけでなく、流路の標高も収集する必要があります。現在、標高を収集する方法はありますか？これまでの調査ではメタデータを使用して高度を取得する方法にたどり着きましたが、私の標高はローカル座標系に基づいている必要があります。<\/P><\/BODY><\/HTML>
Does Collector store the altitude on the z-value of a geometry?
Collector does not support directly storing the altitude on the z-value of a geometry. This will be supported in an upcoming release. Currently, you can capture the altitude values of point features, and use the ProjectZ geoprocessing tool to transfer these values to geometry z-values.

Last I checked, Collect Z values (elevation) using Collector App
~Shan
I believe that the Project Z tool cannot use a Geoid. Therefore the height that you get is Ellipsoid height which is not typically sufficient for modeling stormwater sewer.
Could you or anyone explain more, appreciated.
I second Nizar Salih's request. Any further information is greatly appreciated.
Does this mean the z-values obtained will not be accurate? We need survey grade accuracy, so it is important to determine the reliability. Thank you!! test_collector https://community.esri.com/community/gis/applications/collector-for-arcgis?sr=search&searchId=4dfbd266-f72e-4e58-a5f5-4990ab655275&searchIndex=0
Hi Brita, it is possible to get survey grade accuracy using collector. Check Alison Walker workaround workflow https://frontierprecision.com/achieve-vertical-accuracy-using-esris-collector-app/
Nice job Alison!! This looks great! Really looking forward to this being core sometime soon.
I'm using ArcPro 2.2 and ArcMap 10.5.1, and can't get either the Project-Z OR Alison Walker's workaround to work. The elevation values do not change. Is this a known bug?
