"Revised mapping around Glenmalure - Lugduff." from simon3 Expand pics
Revised mapping around Glenmalure - Lugduff. (Expand pics)
Improved contours.
Context of comment:As you may know, MountainViews offers various layers when displaying maps. (Grey "layers" button at top right of map). One of these is Open Street Map available in two flavours "Mapnik" and "Cyclemap". The latter offers inbuilt contours and layer tinting. The former doesn't so we also offer two additional layers Hillshade and Contours.
Message:An improved form of Hillshade and Contouring has become available and we are trying it out.
To try, go to the layers button, click on Mapnik and tick hillshade and contours.

Stop reading unless you are interested in the tech!

The new layers certainly provide more detail in the contours than any previous map including that from OSi /L&PS. However the academics who provide it, only claim it is experimental and it remains to be seen how accurate it is in practice.

Nowadays the modern approach to creating hillshading and contours starts with a Digital Elevation Model or DEM. In the past maps such as Open Street Map used a variety of data that came from NASA called SRTM, which provided radar height information on a grid of around 91m X 56m (at Irish latitudes). But a series of further missions called ASTER created data with a grid of around 30m X 30 from photogrammetry. Various agencies have combined SRTM and ASTER to create a more accurate DEM and then used it to create contours and hillshading and made these available for free. (View our credits section for more detail.) So, take a look. Bear in mind that the data sources aren't wholly reliable.
Additional points:What would be interesting is to compare some land, in practice, with the new contours.
