11/5/2012 Topic: GPS map of the Anza-Borrego Desert 93ToyTruck	I created a GPS map of the Anza-Borrego desert and the nearby BLM land. It includes Ocotillo Wells, Superstition, Plaster City and Yuha Basin down to the Mexican border. Currently it only works with Garmin but I will be converting it to Lowrance in the future. Check it out and let me know what you think. Lee AnzaBorregoExplorer.com <em>edited by 93ToyTruck on 11/5/2012</em>
11/5/2012 Topic: GPS map of the Anza-Borrego Desert 93ToyTruck	Accurate road data. The freely available topo maps are based on publicly available government data that was collected for the purposes of a topography map. It is aged and typically inaccurate for the purposes of a GPS. If you're only concerned with roads than the detail of a topo map becomes a distraction and make the map difficult to use. The screenshots on the website are from a distance. The detail increases as you zoom in. I've tried all the free maps and purchased a few. They're all USGS data. Lee
11/22/2012 Topic: GPS map of the Anza-Borrego Desert 93ToyTruck	I took screenshots of Butte's Pass using different topo maps and my map. This is a popular and easily accessible area that I would expect to be accurately mapped. The same roads are missing from every topo map. These aren't new roads. I'm certain that they've been there and open for at least the 20 years that I've been in the area. The last screenshot is a rough mark up to highlight the missing information. The maps of the entire area like this. It's bad data that keeps being carried forward. They're all permutations of free government data that is dated. Nobody is collecting, creating or validating new data. The roads and trails they do have marked are inaccurate. A few other examples I see in all of the maps; The Wilson Trial is marked as a jeep trail that you drive on when you can't. Hiking only. The location of the road to Harper Canyon is wrong. All of the maps are about 1/4 mile off. None of the other roads to the valleys off Kane Spring Rd are on any map. There are almost 10 miles of roads missing from that small area. My map also has most of the popular hiking trails mapped out. I thought these were on the topo maps but I don't even see the Pacific Crest Trail. My challenge is that on Garmin receivers the trails look bigger than dirt roads which I find confusing because it makes it look like you can drive on them. The map has 5 levels of detail for zooming in or out. I put the trails only on the bottom level so you have to be zoomed in to see them. This avoids confusion when driving but doesn't help with being able to browse the map for trails because you must be zoomed in to see them. A possible work around is a setting on the receiver to show more detail. I'm going to look into using imagery for some elements instead of only Garmin objects. I'm also going to look into getting the data into an iPhone or Android app. For the screenshots I used Caltopo.com which is one of the topo maps used in BackCountry Navigator. The other screenshots are from Garmin maps including Topo 2011 which is the most recent. Please let me know if there are more accurate maps out there. Everything I'm finding is stale government data.

7/1/2013 Topic: San Diego Trail Map 93ToyTruck	I created a map of all trails and dirt roads on public land in San Diego and Imperial counties and the southern portion of RIverside County. Trails are color coded to indicate if regulations permit hiking, biking, horseback riding or off-roading. The map can be used on Windows or Mac computer as well as Garmin or Lowrance GPS receivers. http://www.SanDiegoTrailMap.com Exclusive Trail Data The vast majority of the trail data was created for this map and is unavailable on any other digital map or even paper. 860 miles of trails for Hiking, Biking and Horseback 500 miles of trails for Hiking and Biking 880 miles of trails for Hiking and Horseback 1,200 miles of trails for Hiking 3,700 miles of trails for Off-Roading, Motorcycles or ATVs 2,700 miles of Dirt Road, Street Legal Only Points of Interest Iconography is used to indicate trail conditions, facilities, businesses, attractions, points of interest or landmarks. Land Boundary and Topo Gradient Backgrounds There are two maps included Topo The Topo map uses a color gradient to indicate altitude. Land Boundary The Land Boundary map uses the background color to indicate land ownership. All Public Lands in San Diego County Open Space Preserves City Parks County Parks State Parks Bureau of Land Management (BLM) Cleveland National Forest (south) California Fish and Wildlife US Fish and Wildlife Nature Reserves Water Authorities Port District Full search functionality quickly locates roads, trails, public lands and points of interest. Currently supports Windows, Mac, Garmin GPS, Lowarance GPS and Android phones/tablets. iPhone support planned for Oct 2013 http://www.SanDiegoTrailMap.com edited by 93ToyTruck on 10/21/2013
