Description: 2023 Broad Scale Mapping of the Catlins / Pounawea Estuary was undertaken by Salt Ecology on behalf of Otago Regional Council and is described in: Roberts KL, Scott-Simmonds T, Rabel H, Stevens LM. 2024. Synoptic Broad Scale Ecological Assessment of Catlins/ Pounawea Estuary. Salt Ecology Report 144, prepared for Otago Regional Council, August 2024. 74p. Ground-truthing was conducted during December 2023. Features were mapped onto 30cm/pixel colour satellite imagery captured 29 October 2023 . Generally, at a digitising scale of 1:2000, spatial accuracy for features clearly visible on aerial photos (e.g. salt marsh, cobble fields, dense macroalgae) is ~2 metres. Spatial accuracy for features difficult to distinguish on aerial photos (e.g., where boundaries represent a habitat transition from mud to sand) is ~10 to 50 metres depending on the extent of ground truthing undertaken. Features were digitised and field codes recorded by Salt Ecology in a master layer. Salt Ecology proprietary scripting tools were used to validate field codes, check for topology errors, produce symbolised output layers and create summary data tables. Dominant estuarine salt marsh species were mapped. Salt marsh species codes combine the two first letters of the Latin species and genus names (e.g. Pldi = Plagianthus divaricatus (ribbonwood)). Vegetation was recorded in order of dominance; e.g Lesi Sare = (Lesi (rushland) dominant to Sare (herbfield)). Vegetation height is able to be derived from the structural class of features; e.g. Lesi (rushland) is taller than Sare (herbfield).
