Eos Arrow receivers give GIS pros real-time data, solid connectability
For pros working in mapping, surveying and other GIS fields, quick, precise data are a must. And the key to getting those data is getting the right receiver. 
 
As a result, many turn to high-accuracy, multi-constellation receivers like the Arrow series built by Eos Positioning Systems. The series includes the Eos Arrow Lite GPS Receiver, Eos Arrow 100 GNSS Receiver and Eos Arrow 200 L1/L2 GNSS Receiver. The receivers are popular for many reasons: They have the flexibility to use multiple satellite constellations, offer real-time data transmission capability and can connect to any device via Bluetooth. 
 
The Arrow receivers use the United States’ GPS constellation of satellites, but they can just as easily link up with Russia’s GLONASS, China’s Beidou and Europe’s Galileo.

In warmer climates like Texas, high reservoir evaporation rates can lead to declines in water level and water availability during droughts, making monitoring essential in order to ensure water security during times of scarcity. 
 
According to the Texas Water Development Board (TWDB), evaporation rates in Texas were previously based on data collected from a sparse network of Class A evaporation stations, dating back to the 1960s. These pans were stationed near reservoirs and still remain a widely accepted standardized approach to measuring evaporation rates on land. 
 
Monthly pan-to-lake coefficients were developed in the 1980s to connect the data collected from the pans to known lake conditions, extrapolating evaporation rates of the lakes using the pan data.
Read MoreA Drop in the Ocean: Restoring London’s Tidal Thames
The United Kingdom has grappled with wastewater management problems for decades. Although sewage treatment in the 20th century allowed many rivers, including the tidal Thames, to have healthy fish populations, combined sewer overflows into rivers–most commonly during heavy rainfall–affected water quality and occasionally even killed fish. 
 
Problems reached a head in 2012 when multiple infractions of European urban wastewater treatment laws threatened costly fines, on top of the environmental cost of repeated sewage spills into British rivers. 
 
Fast forward to 2025, and after a decade of construction work, London’s Thames Tideway Tunnel , affectionately dubbed the “super sewer”, is now fully activated and ready for testing.
