Emerald Island GPS Map

Published since more than one decade on emerald-island.eu, Emerald Island GPS Map is now hosted on lemiage.net.

Emerald Island GPS Map

What's inside ?

Emerald Island GPS Map is based on free open data and tools. Data come from MountainViews, OpenstreetMap, megalithomania and USGS.

mountainViews.ie

openStreetMap.org

usgs.gov

megalithomania.com

MountainViews summits

Data are provided by one of the best hillwalking online resources for Ireland. Created by Simon Stewart, MountainViews is the place to begin for enthousiast hillwalkers in Ireland.

OpenStreetMap data

OpenStreetMap is a free open mapping project. Like Wikipedia, anyone can contribute to this great project.

megalithomania

megalithomania - The home of Irish Prehistory - provides some data about Ireland's prehistoric heritage (rock arts, ogham stones, stones, tombs, burials, holy wells, fortifications...).

SRTM data

Elevation layer (contour lines)

Shuttle Radar Topographic Mission data (SRTM) used for the map are the 1 arc-second resolution (i.e. nearly the same as a 30 m grid samples in Europe). Increased resolution does not mean necessarily a better precision.

  • With SRTM Void Filled, most of the holes in original data are corrected but not in all cases (e.g. some holes are still present in original cell n54_w009).
  • In high areas, contour lines are often at least 10m below the true ground (nevertheless consistent with NASA mission accuracy objectives).
  • For very steep ground, the elevation error can increase a lot. For example, around Faha Ridge the loss is nearly 100 m !

What it means for hill walkers, the contour lines will give you a good idea of the terrain around you with an horizontal approximation of 100 - 150 meters and +/-10 to 110 m elevation error. Do not expect to avoid a cliff with your eyes locked on your GPS screen.

A thought about walking in Irish Mountains

Despite their small height, irish mountains are true mountains. Do not underestimate the difficulties. Before to conquer a summit, check the weather and bring with you clothes you will appreciate to wear if bad conditions catch you. Take enough water and food for all members of your party.
Remember you that a GPS receiver is only a secondary way to find your location. Be sure to be able to find your way back home without your GPS (bringing a paper map and a compass may be a good idea).
If you use to walk only on well marked trails, irish mountains may not be well suited for you. The ground can be "a little" wet and slippery, even on a steep ground. Nevertheless few summits have some more or less marked trails (and not all are official).

Keep in mind this rule : bring back with you what you bring in mountains. Nature is fragile, preserve it.

Support

Why donate ?
Since 2006, Emerald Island GPS Map is available for free because it is built with free data according to their authors and my wish. Garmin GPS devices evolve with new mapping features and I cannot test the map without one. Donations will be used to buy a new Garmin GPS device and, if needed, softwares. Any surplus money will be used to host the website and to support other projects about mapping or for a humanitarian associations.
If you click on the "Donate" button, you will be redirected to a Paypal form.
