Anthony and Nicole,

Nicole is correct,  you wouldn't be able to do this out of the box with just Survey123.  You could do some back end geoprocessing however.  You could collect your geopoint with Survey123 and on the back end at night or every couple of hours or minutes fire of a geoprocessing task that utilizes GeoEnrichment to grab census data with in a mile/2mile/3Mile etc buffer and then you could have the total number of homesteads.  However that is looking at Census data that has already been collected from 2010.  You could also do this with LiDAR analysis to detect volumetric change.  You would need multiple years of LiDAR data to compare but it would show new structures but it may also catch additions made to existing structures too but some simple analysis could probably eliminate additions from the results.

Hey Anthony,

So you want the geopoint from your survey to look for the village in the basemap and retrieve the total number of homesteads, is that correct?

I'm afraid that is not possible with Survey123.

Dear Nicole,

Thank you for your concern over my problem. I want to automatically

calculate the homestead picked with survey 123 as geopoint in a village for

example. The application is for census, so was thinking if it can give the

total number of homesteads picked as the census progress is made.

Thanking you in advance,

Anthony Gakobo.
