  • Threatened to endangered species watershed boundaries based SAIAB and HYDRO1k. Source: SAIAB and HYDRO1k, "river" flow, and watershed networks based on the GTopo30. The AQSP_THRTND_PY shapefile data layer is comprised of 92 derivative polygon aquatic species features derived based on 1:2 000 000 data originally from SAIAB. The layer provides nominal analytical/mapping at 1:2 000 000. Acronyms and Abbreviations: SAIAB - South African Institute for Aquatic Biodiversity; HYDRO1k - Global Hydrological 1 kilometre database of hydrologically filled DEMs; DEM - Digital Elevation Model; GT30/GTopo30 - Global Topographic 30 arc second DEM database, nominal 1km postings.

  • Similar to main aquatic species data layer of capture records of 35 292 verified location references for 247 specie and 1 080 unverified location references for 517 other aquatic specie; includes restricted data for 32 endangered/threatened specie. The AQ_SPECIES shapefile data layer is comprised of 798 derivative point aquatic species features derived based on 1:1 000 000 data originally from FIRI. The layer provides nominal analytical/mapping at 1:1 000 000. Acronyms and Abbreviations: FIRI - Inland Water resources and Aquaculture Service, recently changed in FIMA - Aquaculture Management and Conservation Service
