Automatic Processing of Radar Images for Electronic River Chart Generation in Ecdis Format
MetadataShow full item record
Presenting the navigation environment in electronic format – ECDIS – triggers a major change of the classic method of cartography and raises up the need to approach a way of producing the charts in vector-like format. The present paper is intended to describe a way of processing information (provided by a RADAR system and a GPS receiver), using Kalman filter algorithms and the elements form graph theory, to provide a rough form of an electronic chart. This can be completed afterwards by adding further information so that the chart can become totally compatible with ECDIS standard and can be used in automatic or aided inland navigation.
