@jhaue spatial scale is important for Mangrove wave interaction. Sentinel 2 to drone orthomosaic. #drones #remotesensing

A triptych of satellite regional from Sentinel 2 at 10m resolution on the right. In the centre a section of the regional mosaic is zoomed in to show pixel boundaries. On the left, a subset of pixels is overlaid with a drone orthomosaic showing the features contributing to upwelling radiation.

Small Waterbodies Of Large Conservation Concern - Towards An Integrated Approach To More Accurately Measuring Surface Water Dynamics
--
doi.org/10.1016/j.ecolind.2025 <-- shared paper
--
โ€œHIGHLIGHTS
โ€ข Hydrologic models were used to assess remotely sensed surface water estimates.
โ€ข The accuracy of satellite surface water estimates diminished for waterbodies < 2 ha.
โ€ข Vegetation reduces accuracy of surface water detection, especially during wet years..."

In the coming weeks, weโ€™ll also continue collecting more geophysical data, primarily via magnetometer surveys, so stay tuned for updates!

Inferring River Discharge From Google Earth Images - Critical Flow Theory Can Predict River Discharge Based On The Spacing Of Standing Waves Captured By Google Earth Images

โ€œโ€ฆ KEY POINTS:
โ€ข Standing waves in rivers indicate unique hydraulic conditions that allow depth and velocity to be inferred from the spacing of the waves
โ€ข Critical flow theory can be used to calculate discharge based on measurements of wavelength and width made using readily available images
โ€ข Discharges estimated via the critical flow approach for 82 images agreed closely with discharges recorded at gaging stations (Rยฒ = 0.98)โ€ฆโ€

My academic education was in physics, and until this week I had never seen ยฑ used to mean anything other than 1ฯƒ.

The person who told me that they use ยฑ to describe the 95% confidence interval (i.e. 2ฯƒ) works in remote sensing.

Since I now work in remote sensing, I realize I'm going to have to look at papers and slides much more closely whenever I see ยฑ in the future!

I'm curious as to what other people involved in #RemoteSensing will answer.
