Hydrography (HY) Iceland is one of 12 themes in the European Location Project (ELF). The purpose of ELF is to create harmonised cross-border, cross-theme and cross-resolution pan-European reference data from national contributions. The goal is to provide INSPIRE-compliant data for Europe. A description of the ELF (European Location Project) is here: http://www.elfproject.eu/content/overview Encoding: INSPIRE version 4

This group of maps, which includes the CanMatrix and CanTopo collections, is now a legacy product that is no longer maintained. It may not meet current government standards. Natural Resources Canada's (NRCan) topographic raster maps provide a representation of the topographic phenomena of the Canadian landmass. Several editions of paper maps have been produced over time in order to offer improved products compared to their predecessors in terms of quality and the most up to date information possible. The georeferenced maps can be used in a Geographic Information System (GIS). In all cases, they accurately represent the topographical data available for the date indicated (validity date). The combination of CanMatrix and CanTopo data provides complete national coverage. • CanMatrix - Print Ready: Raster maps produced by scanning topographic maps at scales from 1:25 000 to 1:1 000 000. This product is not georeferenced. Validity dates: 1944 to 2005 (1980 on average). Available formats: PDF and TIFF • CanMatrix - Georeferenced: Raster maps produced by scanning topographic maps at scales of 1:50 000 and 1:250 000. These maps are georeferenced according to the 1983 North American Reference System (NAD 83). Validity dates: 1944 to 2005 (1980 on average). Available format: GeoTIFF • CanTopo: Digital raster maps produced mainly from the GeoBase initiative, NRCan digital topographic data, and other sources. Approximately 2,234 datasets (maps) at scale of 1:50 000, primarily covering northern Canada, are available. CanTopo datasets in GeoPDF and GeoTIFF format are georeferenced according to the 1983 North American Reference System (NAD 83). Validity dates: 1946 to 2012 (2007 on average). Available formats: PDF, GeoPDF, TIFF and GeoTIFF

Seamounts and knolls are ‘undersea mountains’, the former rising more than 1000 m from the seafloor. These features provide important habitats for aquatic predators, demersal deep-sea fish and benthic invertebrates. However most seamounts have not been surveyed and their numbers and locations are not well known. Previous efforts to locate and quantify seamounts have used relatively coarse bathymetry grids. Here we use global bathymetric data at 30 arc-second resolution to identify seamounts and knolls. We identify 33,452 seamounts and 138,412 knolls, representing the largest global set of identified seamounts and knolls to date. We compare estimated seamount numbers, locations, and depths with validation sets of seamount data from New Zealand and Azores. This comparison indicates the method we apply finds 94% of seamounts, but may overestimate seamount numbers along ridges and in areas where faulting and seafloor spreading creates highly complex topography. The seamounts and knolls identified herein are significantly geographically biased towards areas surveyed with shipbased soundings. As only 6.5% of the ocean floor has been surveyed with soundings it is likely that new seamounts will be uncovered as surveying improves. Seamount habitats constitute approximately 4.7% of the ocean floor, whilst knolls cover 16.3%. Regional distribution of these features is examined, and we find a disproportionate number of productive knolls, with a summit depth of o1.5 km, located in the Southern Ocean. Less than 2% of seamounts are within marine protected areas and the majority of these are located within exclusive economic zones with few on the High Seas. The database of seamounts and knolls resulting from this study will be a useful resource for researchers and conservation planners.

Þann 16. mars 2011 gáfu Landmælingar Íslands út í fyrsta sinn sameiginlegt hæðarkerfi fyrir Ísland. Kerfið er kallað Landshæðarkerfi Íslands og er viðmiðunin ISH2004. Tilkoma sameiginlegs hæðarkerfis markaði stór tímamót í sögu landmælinga á Íslandi. Á sama hátt og viðmiðunin ISN93 skapaði grundvöll fyrir alla til að vinna í sama hnitakerfi mun ISH2004 skapa grundvöll fyrir alla til að vinna í sama hæðarkerfi. Eitt samræmt hæðarkerfi er mikilvægt fyrir ýmsar framkvæmdir s.s. vegagerð og jarðgangnagerð og á ýmsum sviðum umhverfisvöktunar, skipulags og áætlanagerðar. Auk þess munu gögnin nýtast við rannsóknir á jarðskorpuhreyfingum eða breytingum á yfirborði sjávar. Mælingar á Landshæðarkerfinu eru standa ennþá yfir og frá fyrstu útgáfu þess árið 2011 hafa bæst við eftirfarandi línur hallamælilínur. • Flókalundur-Bolungavík • Reykjavík-Keflavík • Endurmæling á Suðurlandi vegna jarðskjálftans 2008 • Hellisheiði • Reykjanesbraut-Grindavík • Þjóðvegur 1-Akranes • Kjölur Niðurstöður nýrra mælinga verður bætt inn í þetta gagnasett um leið og þær liggja fyrir.
