UAV-Images dataset over a small intertidal coastal strip within "El Soldado", estuary in Guaymas, Sonora, México.
This dataset contains 314 aerial photographs taken in March 02, 2019 at 9 a.m. (UTC - 07:00) over an experimental site instrumented with an eddy covariance tower and meteorological sensors at "El Soldado" estuary located at the South-eastern margin of the Gulf of California (coordinates). The images were taken with a 16 MP MAPIR Survey2 RGB camera pointed downwards at 90° with a field of view (FOV) of 82°, a shooting interval of two seconds, focal aperture of f/2.8 (default for MAPIR Survey2 Cameras), shutter speed set to 1/125 and ISO 50. The camera was mounted on a commercial-grade Unmanned Aerial Vehicle (UAV, 3DR solo) to perform a 10-minutes flight over the study site with an altitude of 30 m and a horizontal velocity of 4 m/s . Photographs side overlap was set to 75% while the forward overlap was 85%. Flight conditions during the aerial survey were clear sky with wind velocity less than 0.5 m/s. All images were geotagged using UAV flight controller information through the freeware GeoSetter v3.5. This dataset was used as a mapping tool and support for the project: "Caracterización de los almacenes y flujos de carbono en pastos marinos de regiones bioclimáticas contrastantes de México."
