Above the Timber

Why GPS Maps

Above the Timber's high resolution topographic maps coupled with a Garmin mapping GPS receiver bring maps into the 21st Century. No longer do you have to locate physical landmarks and triangulate your position via map and compass, a tedious and error prone procedure. Your Garmin GPS does all that for you . . . instantly.

California Trails

California National Forest and National Park Trails are included on the maps. When available trails are always named and/or numbered. All California National Forest and many BLM trails are represented on these maps. All trails are shown as a bold dashed red line for easy viewing in the field.

Four Maps in One

Each Above the Timber map is actually four separate maps, unlike paper maps or most electronic maps. Even some Garmin compatible maps lack this feature. This 4-in-1 construction is a huge advantage on a small screen handheld GPS, but even on your PC monitor you will appreciate this feature.

Geographic Points of Interest

California has over 30,000 points of interest showing summits, mines, cemeteries, arches, pillars, basins, springs, flats, ridges, cliffs, waterfalls, communication towers, passes and on and on. All points come from the USGS and appear to be based on 100K or 250K data, hence will often not align perfectly with contours.

Forty-Foot Contour Intervals

Elevation contours on Above the Timber's Topos are at 40-foot intervals, the same as standard 7.5-minute USGS Quad maps. Because of the multi-layered nature of the maps, as you zoom out, contours will automatically reduce to 200 foot intervals to avoid contour clutter.

California Roads

The California roads include Interstate to 4WD. Federal and state highways are shown in distinct colors and with unique shields for quick identification. All city streets are included, while not routable, the road features greatly aid navigation. Roads are based on the US Census Bureaus TIGER 2009 data.

California Hydro Data

The High Resolution Water Data is what makes the California maps stand out. Most vector maps only have named water features, named lakes and streams. For every named water feature, their are 100-unnamed water features. To the extent possible with USGS water feature databases, ALL unnamed water features are on these maps. We're talking beaver pond resolution!!!  Additionally, most California rivers are shown at their true extent, bank to bank, not just a line indicating river.

California Wilderness

California has over 80 Wilderness, Wilderness Study, Primitive and Wild & Scenic River Areas from National Forest, National Parks and BLM. All provide a non-motorized experience and share Above the Timber's unique light buff area color for quick identification and high contrast object viewing. Simply hover over the base map in the portion of California of interest to quickly find a wilderness to explore.

California Public Lands

Public lands are shown at 24,000:1 or better resolution if the data was publicly available. Included are National Forest, National Parks, Bureau of Land Management, Federal Wilderness Areas, Indian Reservations, National Wildlife Areas, Military, Bureau of Reclamation, Department of Energy, State Lands, and State Parks.

While great effort was expended in data collection and presentation, Above the Timber assumes no responsibility for the accuracy of these maps. Therefore, the user/purchaser assumes all responsibility for any errors in these maps.

Map-GPS Compatibility

Will Above the Timber's GPS Topo maps work on my Garmin GPS receiver? Almost for certain YES, see the attached samples.

30-Minute Map Segments

Each map segment covers an area of 30 x 30 minutes of arc or exactly 16 - 7.5 minute Quad Maps. These map segments seamlessly join one to another, therefore you can have an entire state as one seamless map inside your GPS receiver.
