Free Topography Maps of Ireland for your Garmin nüvi or Handheld GPS
Yes, that's right, there are free topography maps (contour maps for hillwalking) from the excellent web site,
These maps are suitable for Garmin devices with cartography functions and while principally aimed at the hillwalking enthusiast with a Garmin handheld GPS, the maps can also be downloaded to some Garmin nüvis models for those of you who may only want to use topo maps on occassion. Just remember that your nüvi is not waterproof so it doesn't like rain or getting wet.
The maps are 'homemade' from a number of free online resources including:
- Mountain Views for summits 400m and up regularly updated by Simon Stewart - a site well worth visiting whether your are an occassional or fervent hillwalker.
- The Scottish Mountaineering Club for the geographical toponyms (i.e. place names).
- OpenStreetMap for lakes, rivers, roads, urban areas - a website that demonstrates what can be achieved with enthusiam.
- Megalithomania for megaliths and Irish antiquities - compiled by a man called 'Tom'.
- NASA - Contour lines are extracted from SRTM public available data with interpolation. This means the contours are not as accurate as OSI data however they are perfectly adequate for hillwalking.
Take heed of the warning on Emerald Island - if you intend using your sat-nav or GPS for hillwalking, always make sure that you carry a map and compass, a GPS is only a secondary means of navigation.
