Field Snack #2: Covering the basics of high-accuracy data collection

High-accuracy data collection is often a requirement when adding and inspecting assets on a map. While your phone can provide a location accuracy of a few meters, high-accuracy GNSS receivers can ensure submeter, or even centimeter level accuracy when collecting data.

On this Field Snack, we break down the basics of high-accuracy data collection—covering basic definitions and terminology, the ArcGIS data model for GPS metadata, and how GNSS receivers can be paired with Esri field apps.
