Unlike Google Maps, Geograph CO is completely self-contained, which means that it is
always available, even without any cellular or wireless coverage. It can be used in the field, in the middle of nowhere.
It can of course take full advantage of the iPhone's built-in GPS receiver (this is more limited on the iPod).

HOW DOES IT WORK? |
|
Geograph CO contains a selection of geographical information in its internal
database -- 31 by default. A number of additional layers are also available for download (15 as of this writing).
Each layer can be individually
shown or hidden, moved up or down, and made more or less transparent. This allows an almost
infinite number of possible displays.

Each feature of most layers has additional information which can be displayed by
tapping the feature. This brings up a list of all the data in all the displayed layers at that point.

The user can then select the desired layer and get all the available information. For instance,
tapping a data point in the Oil Well layer brings up a screen similar to the following:

With Geograph CO, you can finally access data that is relevant to you
without needing access to a computer or a network.
