"The ultimate app for Geography/Geology amateurs and professionals."
- Mel Martin,

Geograph WA/OR is the edition of the popular GIS (geographic information system) covering Washington state and Oregon. It is a self-contained application (no Internet or cellular access required) that contains a vast amount of information about the geology and geography of the two states. It is fully GPS-enabled, allowing you to better understand the landscape around you as you move around the state.

This release contains 25 layers, which can be combined in any desired way:

- states outlines
- the complete geological map from USGS
- terrain elevation
- bathymetry (ocean depth)
- seismic hazard level
- all 1,930 earthquakes in recorded history over 3.0 magnitude
- plate boundaries
- quaternary faults
- old faults
- volcanoes
- public land ownership
- hydrologic units
- USGS quadrangles
- township and range
- urban areas
- counties
- hydrology
- roads and major streets
- railroad tracks
- cities and towns
- active mines
- potassium/argon dates
- state plane zones
- UTM zones
- main aquifers

For more details on these layers, see our web site

There have been a number of improvements since the release of the sister programs Geology CA, Geology TX, Geology NY, and Geograph FL. New layers have been added. The terrain layer is now much more detailed. Performance has been further improved. A few minor bugs have been fixed.

What's New in Version 1.1

This is a major upgrade, with a lot of new layers:

- annual precipitation
- ZIP codes
- almost 18,000 mineral resources
- ecological regions
- significant forest fires (2001-2008)
- surface material

There are many additional layers available for download:

- all 41,046 geodetic points in WA and OR
- WA legislature districts
- OR state house and senate districts
- elementary, secondary and unified school districts
- city boundaries
- American Indian areas
- over 10,000 landmark points and areas
- 5,120 railroad crossings
- airports with link to FAA site for details
- national parks boundaries

with more layers to be added.

Several bugs have been fixed. Bookmarks can now be saved and shared by email. The name has been changed because the application now covers much more than just geology.

Customer Reviews

Good, but missing one major function

I really like this app, but I could actually use it for MANY more things if I could type in a GPS position. Since the iPod lacks GPS, as do most iPads, and the GPS in iPhones leaves much to be desired when you're out in the parts of Oregon with interesting geology, I'd like to enter data from my GPS to get geologic and geographic info.

Still impressive

I gave this app 5 stars when it came out and I maintain my rating. If anything, this release is even better with many additional downloadable layers. Keep up the good work!


This app is perfect! I use it to tutor college level and higher Geology. It gives other students more information than they would on a map.
