The orthomosaic covers an area of approximately 18,800 m2 where a meteorological tower and eddy-covariance instrumentation were deployed. The data were used to support the project: "Caracterización de los almacenes y flujos de carbono en pastos marinos de regiones bioclimáticas contrastantes de México." A MAPIR Survey2 RGB camera was pointed downwards at nadir (90°) with a shooting interval of two seconds. The flight conditions during the aerial survey were: wind less than 0.5 m/s and clear sky. Flight duration was 10 minutes. Sidelap overlay was set to 75% and frontlap overlay was 85% . Horizontal Field of View (HVOF) was set to 82°, flight altitude was 30 m whereas flight speed was 4 m/s speed. A total of 314 photographs were used to construct the rectified orthomosaic. Image central coordinates are 27°57'14.4" N and 110°58'19.2" W (which represents the location of the meteorological tower). Orthorectified mosaic was created using 3D reconstruction and image processing software AGISOFT® Photoscan (now Metashape). No GCP were used in the processing, however; orthomosaic coordinates were assign by camera internal GPS. All processes were set at high quality. Dense point cloud composed by 93, 956, 486 points. Image resolution acquired was 1.1 cm/pix General file description for Estero soldado geotiff https://hs.pangaea.de/Maps/Mexico/UAV_Estero_soldado/file_description_esterosoldado_guaymas.pdf Reporte RGB ESTERO SOLDADO https://hs.pangaea.de/Maps/Mexico/UAV_Estero_soldado/Estero_Soldado_Report_020319.pdf https://download.pangaea.de/reference/100084/attachments/Estero_Soldado_Report_020319.pdf -110.9725 -110.9725 27.954 27.954 -110.9725 27.954 not specified CONACYT Caracterización de los almacenes y flujos de carbono en pastos marinos de regiones bioclimáticas contrastantes de México Sonora Institute of Technology ITSON https://www.itson.mx/Paginas/index.aspx https://ror.org/01v10fv91 Consejo Nacional de Ciencia y Tecnología CONACYT https://doi.org/10.13039/501100003141 278608 Caracterización de los almacenes y flujos de carbono en pastos marinos de regiones bioclimáticas contrastantes de México / CONACYT-278608 Consejo Nacional de Ciencia y Tecnología CONACYT https://doi.org/10.13039/501100003141 286494 Caracterización de los almacenes y flujos de carbono en pastos marinos de regiones bioclimáticas contrastantes de México / CONACYT-286494 Estero_soldado 27.954 -110.9725 Mexico Unmanned aerial vehicle UAV 1.1 CC-BY-4.0 Creative Commons Attribution 4.0 International https://creativecommons.org/licenses/by/4.0/ citable Coastal Drone orthomosaic UAV author69935 author69936 award154 award244 event2908218 funder20680 geocode1600 geocode1601 inst20681 license21 method11909 project4325 ref100081 ref100084 term23880 term47172 term47173 term48030 term49575 topotype1
