# GIS Integration

Geographic Information Systems (GIS) have traditionally relied on low-accuracy GNSS for creating map layers. Nowadays, users can opt for centimeter-level accuracy with RTK GPS, which has become more affordable and is in demand for precise projects. Consequently, RoboDot is a viable option for cost-effective and accurate GIS operations.

NMEA sentences are transmitted from RoboDot to GIS applications through TCP, Bluetooth (LE), and Serial connections.

**RoboDot should be set up as a Rover when used with GIS and Surveying applications**

## Compatible Applications

RoboDot expands its functionality by interfacing with a multitude of device applications to replace their internal, often inaccurate GPS systems. Through robust connectivity options like Bluetooth Low Energy (BLE), Serial, and TCP, RoboDot offers versatile integration possibilities. For instance, popular GIS and surveying apps can effortlessly connect via these protocols to leverage RoboDot's centimeter-level accuracy, enhancing the overall mapping precision. Many applications share similar integration interfaces, ensuring that RoboDot can seamlessly maximize operational potential across various devices, whether through a WiFi network, BLE, or Serial connections.
