| Getmapping Release New Mapping Datasets Getmapping has released a number of new datasets including LiDAR elevation data captured by the Environment Agency. In addition there's Getmapping's own digital terrain model, People's Map GB 100m contours, 1:1m vector data, national administration boundaries and a place name gazetteer made up of over 39,000 different names. All datasets are available from Getmapping.com except for LiDAR, which can be bought through the sales team. Getmapping now sports the most comprehensive collection of height data currently available at accuracy and price points to suit a wide range of applications from flood modelling to wind farm impact assessments. At the high end there is Environment Agency LiDAR data which has a vertical accuracy in the range of 5cm to 15cm, with postings ranging from 1m to 2m. Constantly updated there is now more than 60% coverage of England and Wales, including many major urban areas and rural flood plains. Getmapping's own height data, is now available for Wales and Scotland, with England to follow during 2010. The new workflows and algorithms used to produce this data from Getmapping aerial imagery are the result of a DTI funded Knowledge Transfer Partnership (KTP) and deliver perhaps the best balance between accuracy and cost. Other height data available from Getmapping includes the complete range of Intermap's NEXTMap Britain radar derived digital elevation models. Getmapping has also introduced a number of People's Map datasets all available online from Getmapping.com. A 100m interval contour dataset covering the whole of Great Britain, Northern Ireland and the Republic of Ireland, is particularly useful for the creation of large scale maps to indicate relief. Other People's Map data includes a 1:1m vector data set of Great Britain and national administration boundaries. Finally, there is a 39,000 plus geo-referenced place name gazetteer. All of these datasets represent extremely good value for money. write your comments about the article :: © 2010 Computing News :: home page |
