Mapping, GIS Analysis, and Web Page Development

Map samples:

We created over 50 shaded relief maps for the soon to be published
Mountain Bike Ride Guide for Lane County, second edition,
by Dan Geiger and Keith Nelson.

Here is the Index Map for the book:

Click in one of the red circles or on a trail name under the map to view a low resolution trail map.

See the Guide Book for details

There are sample images of 1 Cummins Creek; 3 Ridgeline Trail; 5/6 Shotgun Creek;
20 Alpine Trail; 21 Aubrey Mtn ; 23 Dead Mtn; 30 Blair Lake; 34 Waldo Lake;
36 Chucksney Trail; 42 O'Leary Trail.

We helped to develop the brochure: Track Town, USA, A Runner's Map for Eugene/Springfield Oregon

These trifold 11" x 17" maps are available free in and around Eugene, Oregon at various running outlets, Visitor Centers, and at the Prefontaine display at the airport.

Click in the image for a larger image (98KB). Here's the title page and description of running in the Eugene/Springfield area.

We created the map for a portion of the Eugene to Pacific Crest Trail that was used on the 15km race T-shirts:

GIS Analysis samples:

We are doing spatial analysis of the Middle Fork Willamette Watershed to evaluate the condition of the watershed.

We produced the Ecoregion Map of Lane County for The Native Plant Society of Oregon, Emerald Chapter for inclusion in an upcoming publication.

We have the capability to convert planimetric/topographic information into "3D" shaded relief images. An example of a bathymetric map is shown for Waldo Lake, Oregon

Located in the Oregon Cascades at 5,248' elevation, Waldo is one of the purest lakes in the world.
The bathymetric map on the right was created from the image on the left.
Click in the bathymetric map for a surface view of Waldo Lake.

Much of what we do involves combining data from several different sources and in different formats. The Oak Savannah page is an example of an aerial photograph merged with a USGS topographic map and a vector layer of roads.

Web Page Design sample:

We created several maps for the Benton County Parks Department and developed the Benton County Parks Web Page which combined the maps with management plans, historical information, facilities rental, etc.
