The Front Cover

As a result of the rapid growth in the offshore wind sector, the demand for spatial environmental data is constantly increasing. Traditional visual aerial survey methods suffer from reliability, safety and data quality drawbacks. These can be overcome by new digital methods, and in the article on page 6 the author discuss the application of these new technologies to offshore aerial bird and mammal surveys. The image on the cover is an example of a high-resolution image collected while on survey. (courtesy APEM Limited).
