These data were used to evaluate the digital elevation model (DEM) acquired by photogrammetry. The vertical differences between GCPs and the DEM were evaluated by equation Zdif = ZDEM - Zgrd, where Zdif = the vertical differences, ZDEM = the Z value of the DEM, and Zgrd = the Z value of the GCPs. -90.27262901 -90.15326900000002 29.108411 29.40220097 -90.17575313404501 29.122463036741557 0.0 2.09 point Conselho Nacional de Desenvolvimento Científico e Tecnológico https://doi.org/10.13039/501100003593 CNPQ 403239/2021-4 Impacts of the climate change on the boreal and austral American mangroves limits during the Holocene and Anthropocene Port_Fourchon-Louisiana 29.122 -90.176 356 CC-BY-4.0 Creative Commons Attribution 4.0 International https://creativecommons.org/licenses/by/4.0/ Ground control point GCP Cohen Marcelo Cancela Lisboa mcohen80@hotmail.com 0000-0001-9892-4719 GCP LONGITUDE Longitude http://en.wikipedia.org/wiki/ISO_6709 Cohen Marcelo Cancela Lisboa mcohen80@hotmail.com 0000-0001-9892-4719 Longitude LATITUDE Latitude http://en.wikipedia.org/wiki/ISO_6709 Cohen Marcelo Cancela Lisboa mcohen80@hotmail.com 0000-0001-9892-4719 Latitude ELEVATION Elevation m a.s.l. http://en.wikipedia.org/wiki/Elevation elevation http://purl.obolibrary.org/obo/PATO_0001687 Length L http://dbpedia.org/resource/Length Cohen Marcelo Cancela Lisboa mcohen80@hotmail.com 0000-0001-9892-4719 Elevation [m a.s.l.] Longitude, difference Longitude diff Cohen Marcelo Cancela Lisboa mcohen80@hotmail.com 0000-0001-9892-4719 between observation by photogrammetry and observation in the field by a topographic survey Longitude diff Latitude, difference Latitude diff Cohen Marcelo Cancela Lisboa mcohen80@hotmail.com 0000-0001-9892-4719 between observation by photogrammetry and observation in the field by a topographic survey Latitude diff Elevation, difference Elevation diff m elevation http://purl.obolibrary.org/obo/PATO_0001687 Length L http://dbpedia.org/resource/Length Cohen Marcelo Cancela Lisboa mcohen80@hotmail.com 0000-0001-9892-4719 between observation by photogrammetry and observation in the field by a topographic survey Elevation diff [m] CurationLevelC Enhanced curation https://wiki.pangaea.de/wiki/Curation_levels citable author25893 award1824 curlevel30 event3035879 funder20910 geocode1600 geocode1601 geocode8128 license21 param510229 param517236 param517237 param517238 pi25893 term1073934 term43863 topotype2
