How to use RTK kit with CarryMap app for forestry mapping
In this tutorial, you will find detailed steps on how to use the free CarryMap app for precise, real-time mapping of trees with centimeter-level accuracy using our RTK kit. This app allows users to create and edit points and polygons, record GPS tracks, and add photo attachments.
CarryMap supports external GPS/GNSS receivers but does not have a built-in NTRIP client. For this reason, we will use GNSS Master to receive real-time RTK corrections over the internet and improve measurement accuracy to the centimeter level. By pairing your ArduSimple RTK kit with CarryMap, you can achieve centimeter-level accuracy in your fieldwork.
Before starting this tutorial, make sure you have the credentials to connect to an NTRIP service. If you’re unsure about NTRIP services in your area, we’ve prepared a list of services specific to your country.
