Digital orthophotomap of a harbor as a primary cartometric data source in LIS support of harbor management

The paper presents creation and potential applications of a digital orthophotomap of a harbor. Possibility of frequent updating and the amount of information it contains make it the primary cartometric material of a harbor. A strange rescue team conducting a rescue mission in a harbor using Land Information Systems data based on an actual orthophotomap has much greater chances for a successful action than a team deprived of such data. Furthermore, using an orthophotomap in LIS by the harbor authority seems to be the only appropriate solution. According to NATO standards, each military harbor should have an orthophotomap in the scale of 1:5000 (analog version). However, it is not currently used in LIS support of t harbor management.
