Mapping Erosion at Archaeological Sites with GNSS


Archaeologists have long been using Global Navigation Satellite System (GNSS) technology to map and survey archaeological sites. However, the accuracy and precision of GNSS receivers can vary, making it difficult to produce highly detailed maps. The GNSS receivers made by Canadian company Eos Positioning Systems®, offer sub-metre accuracy and the ability to connect to multiple GNSS constellations. This makes it ideal for mapping and monitoring erosion at archaeological sites, which can help preserve and protect valuable historical resources for future generations.

By using the Eos GNSS receivers to map erosion at archaeological sites, researchers can create highly detailed maps that show the extent and severity of erosion. This information can be used to develop strategies for protecting and preserving archaeological resources, such as redirecting water flow or installing erosion control measures. The high accuracy and precision of the Eos Arrow 100® and Arrow Gold® GNSS receivers also enable researchers to accurately measure changes in topography over time, which can help identify areas that are at risk of erosion and inform long-term management plans.

Eos Positioning Systems is on a mission to bring affordable, high-accuracy Bluetooth GNSS (GPS) location to any device – including iOS, Android, Windows and Windows Mobile. As such, the EOS technical team built the world’s first device-agnostic Bluetooth GPS receiver capable of providing submetre and centimetre accuracy to any device.
