Can I capture both points and polygon features using one single Survey 123 form?
Values for geo type questions (geopoint, geoshape, geotrace) are stored in the SHAPE column of your surveys feature layer. The ArcGIS geodatabase model only allows for one single SHAPE (geometry) column per feature layer, so this restricts the number of geo questions you can add to a survey to one: either one geopoint, or one geoshape, or one geotrace question.
The only exception is when you add repeats to your survey: each of your repeats can also include its own geo question.
For example, with our Household survey, let’s pretend you want to use a geopoint question to document the household location of the respondent, and then you want capture land parcels (geoshape) of the respondents. You could create a survey as follows:
