Frequent Questions

What is an outcrop?

Geologists study the structure and history of the Earth, and specifically its rocky interior. Although complex and expensive equipment is used for such studies, a lot of information about the history and composition of the Earths interior can simply be obtained by having a close look at rocks in mountains, along roadsides, and any other site at the Earth's surface. If a rock mass is visible at the surface, a geologists will say that the rock mass "outcrops". Isolated masses of rock are named "outcrops" by geologists. Most of these outcrops are made of single, homogenous kind of rock, such as granite, but in many cases rocks are layered or cleaved, or show more complicated patterns on their surface. At high temperature and pressure inside the earth, rocks can move slowly like honey flowing from a pot, or can break creating earthquakes. These data can be used to reconstruct what happenedin the history of the rock. The Outcropedia is a website meant to show a collection of such outcrops.

What are the file requirements for uploading a new outcrop?

Coordinates of your outcrop should be in latitude-longitude for WGS84 datum, and in the form of digital degrees. These are negative for the southern hemisphere and locations west of Greenwich. For example Paris would be entered as lat 48.85667, lon 2.350987; Buenos Aires as lat -34.608418, lon -58.373161 . Remember that 5 decimals are normally accurate enough for a place indication, since they represent metre-scale accuracy

Text should be less than 250 words, and be preferably in english, but other languages using latin script are allowed.

Images could be photographs or in exceptional cases drawings. These must be in .jpg/.jpeg format. Avoid large images of high resolution, since this resolution cannot be displayed in GoogleMaps. A resolution of 800 X 600 Pixels at 72 dpi is sufficient.
