Thermal Waterway Inspections
Remote sensing has long been used for riverine and riparian inspections. Using thermal sensors to identify areas of ground water upwelling, surface water runoff, point-source pollution, seeps and other features can provide novel insights when characterizing a waterway.
Larger, more advanced devices like Infrared, LiDAR and Multispectral sensors have been the exclusive domain of manned aircraft and satellites. For decades, remote sensing professionals have been using these tools to help characterize large swaths of land in new and exciting ways. In the environmental field, a myriad of techniques have been established that utilize these large aerial infrared sensors, from monitoring streams and wetlands, to mapping volcanic activity.
One of the biggest constraints of these efforts has traditionally been the resolution of the captured data. By mounting a high-resolution Infrared sensor on a UAV, we're able to overcome this hurdle and push the limits of remote sensing to the next level. The newest LANDSAT imagery has a typical resolution of ~30m. Manned aircraft can achieve results closer to 30cm. UAVs on the other hand can easily achieve resolutions of 3cm.
This leap in available resolution for overhead maps and remote inspections has facilitated the quick, safe and cost-effective acquisition of data previously only available to individuals on the ground. The ability to combine this high-resolution sensor data with traditional photogrammetric techniques allows us to generate highly accurate georeferenced maps of large properties, an actionable work product that has not been commercially available to environmental professionals until very recently.
With this new data, we can begin to map and model things like ground water discharge, seeps, stream confluence, surface water input, soil contamination and point source pollution with high accuracy and speed.
