Standardize the coordinate precision of a geopoint question in ArcGIS Survey123 Connect

Summary

In ArcGIS Survey123 Connect, a geopoint question is used to capture a point location in a survey. By default, the latitude and longitude values of a selected point are stored with varying decimal precision. To standardize this precision, the 'decimal' question type can be used to populate the geopoint’s latitude and longitude values with a fixed number of decimal places, ensuring consistent and reliable data for analysis and integration. This article outlines the workflow to standardize the decimal precision of a geopoint question.

Procedure

1. In ArcGIS Survey123 Connect, open the survey’s XLSForm.
2. Configure the latitude value.
1. In the survey worksheet, in the type column, click an empty cell and select decimal from the drop-down list.
2. Specify the values in the name and label columns. In this example, 'lat' is specified as the name and ‘Latitude:' is specified as the label.
3. In the calculation column, insert the expression below. Replace <geopoint_name> with the name of the geopoint question and <decimal_place> with the preferred number of decimal places. In this example, the name of the geopoint question is ‘location’ and the decimal place is ‘8’.

round(pulldata("@geopoint", ${<geopoint_name>}, "y"), <decimal_place>)

3. Repeat Step 2 to configure the longitude value. In this example, 'lon' is specified as the name and ‘Longitude:' is specified as the label. In the expression, the x property is used.

round(pulldata("@geopoint", ${<geopoint_name>}, "x"), <decimal_place>)

4. Save and close the XLSForm.

The latitude and longitude values of the geopoint question are populated with the preferred number of decimal places when a location is selected, ensuring consistent coordinate precision across the survey.
