Cartographic Rules and Differences in Nautical Data Visualization on Paper and Electronic Nautical Charts
This paper aims to present cartographic rules for the production of paper and electronic navigational charts and main differences in compilation, visualisation and representation of nautical information. Major differences between paper nautical charts and ENC are visualisation of nautical data: colour mixing, resolution of represented nautical objects, human control of display representation an...
متن کاملGhost reefs: Nautical charts document large spatial scale of coral reef loss over 240 years
Massive declines in population abundances of marine animals have been documented over century-long time scales. However, analogous loss of spatial extent of habitat-forming organisms is less well known because georeferenced data are rare over long time scales, particularly in subtidal, tropical marine regions. We use high-resolution historical nautical charts to quantify changes to benthic stru...
متن کاملAn Ontology for the Generalisation of the Bathymetry on Nautical Charts
On nautical charts, undersea features are portrayed by sets of soundings (depth points) and isobaths (depth contours) from which map readers can interpret landforms. Different techniques were developed for automatic soundings selection and isobath generalisation from a sounding set. These methods are mainly used to generate a new chart from the bathymetric database or from a large scale chart t...
متن کاملLiDAR Bathymetry for Nautical Charting
Safety Of Life at Sea (SOLAS) is the overarching principle for all offshore operations and one of the major contributing factors to SOLAS is quality navigational charts that are comprehensive and adhere to International Hydrographic Organisation (IHO) established standards of accuracy. However, a chart is only as good as the data that is used to compile it and one of the more challenging areas ...
متن کاملThe Nautical Archaeology Digital Library
In Nautical Archaeology, the study of components and objects creates a complex environment for scholars and researchers. Nautical archaeologists access, manipulate, study, and consult a variety of sources from different media, geographical origins, ages, and languages. Representing underwater excavations is a challenging endeavor due to the large amount of information and data in heterogeneous ...
