Calculate distance of geopoint location to the nearest line feature in ArcGIS Survey123.

KushShah

Hi ArcGIS Survey123 community!

I am having an issue with calculating distance of geopoint location to the nearest pipeline feature using survey123 connect in arcgis enterprise environment. Essentially, when the user added geopoint location in the survey123 form map window, it needs to be dynamically populated/displayed the distance value of geopoint to the nearest pipeline feature in one of the geopoint's attribute column of the form template. Not sure if there is a workaround using layer pull function or javascript expression. Any help/suggestion will be  greatly appreciated. 

Thanks,

I don't think there is a straight forward solution to this, the functionality is currently not part of survey123.

You may be able to sort of replicate the functionality but may take a couple steps.

1.  Convert your pipeline line feature to points, keeping all relevant info in the point layer.

2. With point layer create a Thieseen Polygon layer. Ensure the X,Y info for the point is captured in the polygon along with any other relevant info. Host this feature layer so it can be queried.

3. With your geopoint question, use pulldata point in polygon to retrieve the X and Y data from your hosted Thieseen polygon feature that the geopoint lands in.

4. Calculate the distance:

Another thought would be: Have the user identify on a map, the closest pipeline by adding a second (nulled) geopoint question using the pipeline map as the source, then calculate that distance between the two points.
