Parque Natural Metropolitano metrop plot tree crown map and liana map 2024

The Parque Natural Metropolitano (PNM) is a national park established under Law 8 on July 5, 1985. Spanning an area of 232 hectares features tropical dry forest and tropical rain forests, it is located within Panama City. Within this park lies the metrop Plot, a research site established by the ForestGeo network in 2020 with dimensions of 100 x 100 meters. This plot has been sampled five times by the ForestGeo network, with all trees above 1 cm DBH tagged and measured annually. The most dominant species within the plot is Castilla elastica, and the plot contains a total of 46 species of woody plants.The crown map is provided as a GeoDataFrame in .shp format with the geometric coordinate reference system UTM 17N (EPSG:32617). Each row corresponds to a geometry representing the vertically projected area that each individual tree occupies at the top of the canopy. The geometries were delineated and validated in the field using a canopy crane. Key features recorded during validation include crown completeness, tree crown liana load, crown illumination, flowering (boolean), senescent leaves (boolean), fruiting (boolean), and leaf cover percentage of the crown. Detailed information about these variables is available in the README.txt included in the dataset. A collection of orthomosaics from this plot are provided in doi:10.60635/C36P46.Similarly, the liana map contains geometries for clearly visible patches of lianas at the top of the canopy, with associated variables recorded for each patch. Due to the co-occurrence of liana species in the canopy, patches may represent multiple species.We provide the following resources:A zipped folder for the crown map: PNM_metrop_2024_crownmap.zipA zipped folder for the liana map: PNM_metrop_2024_lianamap.zipAn orthomosaic used for data collection: PNM_metrop_2023_12_19_orthomosaic.tif
