The Use of Close Range Photogrammetry for Studying Ice Accretion on Aerofoil Sections

This paper describes the use of photogrammetry to measure and quantify ice accretion on an aerofoil section. A series of stereoscopic photographs was taken during the ice accretion on the section in an icing tunnel. From measurements made on these photographs with a Kern (Leica) DSR 14 analytical photogrammetric plotter, a series of three dimensional models of the ice surfaces was constructed. The results of the project are discussed and possible improvements in the methodology are suggested.

The state of mapping in the former satellite countries of Eastern Europe

Since the breakup of the former Eastern Bloc and the emergence of newly independent states from the former Soviet Union, there has been a more liberal approach to the publication of maps. Types and scales of maps which had formerly been available only to the military or planners are now being sold freely to the general public and to foreigners. Freed from the straitjacket of military requirements and censorship, a number of the former Eastern Block countries are also producing a much wider range of map types. This paper explores both the types of maps formerly produced in the satellite countries of Eastern Europe and those being produced under the new, more liberal regimes.

Mapping the intertidal vegetation of the harbours of southern England for water quality management

This paper discusses a research project dealing with the mapping of the intertidal vegetation of several harbours along the southern coastline of England. It describes in detail the methods used to map the vegetation and gives examples of the results from these studies. This paper then goes on to explain how these results are applied by the Environment Agency of England and Wales to improve water quality in the harbours. This type of vegetation mapping is useful in monitoring the development of the intertidal species includingSpartina, Zostera and of particular importance to this study the green algaeUlva andEnteromorpha. The work was undertaken with funding from the Environment Agency and at present has taken place over a four year period. The data collected will be used by the Environment Agency to assess macro-algae covervalues for the intertidal area of the harbours concerned. This forms part of the Agencys commitment to the EU Nitrates Directive and the Urban Waste Water Treatment Directive. Some of the species mapped act as suitable indicators of water quality and are symptoms of entrophication. Other species are of interest for nature conservation and were recorded to provide a record for longer-term trends in vegetation patterns within the harbour. This paper aims to provide readers with an understanding of the techniques involved as well as an evaluation of the methodology.

The State of Mapping in the European Republics of the Former Soviet Union

Since the emergence of newly independent states from the former Soviet Union, there has been a much more liberal approach to the publication of maps. Types and scales of maps which had formerly only been available to the military or planners are now being freely sold to the general public and to foreigners. Freed from the straitjacket of military requirements and censorship, a number of the former Soviet republics are also producing a much wider range of map types. This paper explores both the types of maps produced in the former Soviet republics and those being produced under the new, sometimes more liberal regimes.
