This paper sets out to discuss ongoing activities in the tide and chart datum components of hydrography and charting. It expands on the paper presented at FIG (Fédération Internationale des Géomètres) in Brighton 1998 by Mr Matt Higgins and is a revised and updated version of the paper Chart Datum for Hydrography by GPS delivered by the present authors to the Survey 99 Congress, Sunshine Coast,...

We present new Holocene and glacial dO data measured on planktonic foraminifera Neogloboquadrina pachyderma and benthic foraminifera Cibicidoides species from the Atlantic and Pacific sectors of the Southern Ocean in order to better understand its glacial hydrography. Combined with previously published data, the latitudinal dO distributions of these foraminifera show no appreciable difference d...

My big unsolved problem: Invent mathematics to easily represent legal terrain (elevation). Terrain properties: many maxima • few minima • often monotonically decreasing • occasional discontinuities. Applications: To put terrain operations like visibility, hydrography, compression on a proper formal foundation • To process large databases. Tools: very large memory • parallel HW (openMP, CUDA).
