anonymous 16352 Typology approach from visual interpretation of satellite imagery for reef passages around 9 South Pacific islands Nozik, Alexandra; Breckwoldt, Annette; Becker, Ronja; Fache, Elodie; Piovano, Susanna (2022): Typology approach from visual interpretation of satellite imagery for reef passages around 9 South Pacific islands [dataset]. PANGAEA, https://doi.org/10.1594/PANGAEA.942568 Data was collected as part of the SOCPacific project. Dealing with challenges of the pandemic and travel restrictions, project participants aimed to develop a typology of reef passages based on visual interpretation of freely available satellite imagery. Nine islands of different sizes and shapes surrounded by coral reef structures were selected based on previous field expertise. Reef passages were mapped in GoogleEarth and further processed in QGIS (version 3.16) and R (version 3.5.3). In addition, outlines for the selected islands were downloaded from the GADM database (gadm.org). Parameters distance to coast, minimal width of the passage and the assigned type were added to the dataset. Passages were assigned one of three types defined in Breckwoldt et al. (2022) - Coastal, Lagoon or Open Ocean - depending on the geomorphological appearance of the reef and distance to the coast. The CRS of the dataset is WGS84. 16360 https://doi.org/10.1594/PANGAEA.942568 2022-03-22T11:18:45+0000 2022 19870 20110 20108 20106 20104 20102 20100 20098 20096 20094 20092 20090 20088 20086 20084 20082 20080 20078 20076 20074 20072 20070 18177
