NOAA Shallow-Water Benthic Habitats: Northwestern Hawaiian Islands: Midway

Description

Benthic habitat maps for the nearshore, shallow (< 30 m) coastal waters of Midway Atoll in the Northwestern Hawaiian Islands (NWHI) and the Papahanaumokuakea Marine National Monument. NOAA's National Centers for Coastal Ocean Science (NCCOS) produced these data to support coral reef research and management. Habitat regions were digitally identified using visual interpretation of orthorectified satellite imagery with a minimum mapping unit (MMU) of approximately 100 square meters (1/40 acre). A slightly different benthic habitat classification scheme was used for the NWHI compared to the Main Hawaiian Islands (MHI) and other regions across the Pacific (e.g., American Samoa, Guam, and CNMI). While many classes are similar, they are not categorized as biological cover types, geomorphological structure types, and geographic zones. Instead, a hierarchical scheme was used to flexibly denote substrate category (e.g., unconsolidated and hardbottom), structure (e.g., linear reef or pavement), and cover (e.g., coral, coralline algae, or macroalgae). A total of 45 detailed benthic habitat classes were identified within the NWHI. For simplification and to more easily distinguish cover types, these are presented in a set of 7 aggregated benthic habitat classes including 5 hardbottom substrate classes (live coral, coralline algae, macroalgae, uncolonized, and unknown biological cover) and 2 unconsolidated substrate classes (macroalgae and uncolonized). Query an aggregated polygon to get the detailed benthic habitat classification at the clicked location.

52 Open Geospatial Consortium Web Map Service (WMS). Supported WMS versions include 1.1.1 and 1.3.0. Supported map formats include AtomPub, GeoRSS, GeoTIFF, GIF, JPEG, KML/KMZ, PDF, PNG, SVG, and TIFF. Supported info formats include GeoJSON, GeoJSON-P, GML, HTML, and plain text. http://geo.pacioos.hawaii.edu/geoserver/PACIOOS/hi_noaa_mdwy_benthic_habitats/ows?service=WMS&version=1.3.0&request=GetCapabilities
51 Open Geospatial Consortium Web Feature Service (WFS). Supported WFS versions include 1.0.0, 1.1.0, and 2.0.0. Supported output formats include CSV, GeoJSON, GeoJSON-P, GML, KML, and Shapefile (Zipped). http://geo.pacioos.hawaii.edu/geoserver/PACIOOS/hi_noaa_mdwy_benthic_habitats/ows?service=WFS&version=1.0.0&request=GetCapabilities
52 Open Geospatial Consortium Web Map Service - Cached (WMS-C). Use of WMS-C is similar to traditional WMS but with the addition of the "tiled=true" parameter, which triggers GeoServer to pull map tiles from GeoWebCache if they have been previously generated. This can dramatically improve performance, especially for larger datasets. Supported map formats include JPEG and PNG. Supported info formats include GeoJSON, GML, HTML, and plain text. http://geo.pacioos.hawaii.edu/geoserver/PACIOOS/gwc/service/wms?service=WMS&version=1.1.1&request=GetCapabilities&tiled=true
