Geograph FL

What if you could hold Florida in the palm of your hand?

Geograph FL is the Florida version of the first GIS (geographical information system) for the iPhone.

This latest release contains many more layers and improved functionality.

 
 
Unlike Google Maps, Geograph FL 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 FL contains a selection of geographical information in its internal database. It can display this information in over 40 different layers. 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 an area of the Sinkhole Types layer brings up a screen similar to the following:

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