Its always a good idea to pack paper maps before going on an outdoor adventure and now TopoShare.org enables users to create high resolution paper maps with routes from the site. Click the Acrobat icon below the route map and the PDF generator screen appears. Here you can drag the map to the right position and change the scale and paper orientation. You can then select a base map. The base map is requested from the web service in high resolution and it can take a while to get (about 5-6 mb of data). When ready hit ‘Make pdf’ and shortly after the pdf is ready for download.

I’ve experienced that the browser return a blank page after clicking ‘Make PDF’. Just try to hit the reload button on your browser. I’ll try to fix this bug.

Before you complain about Big Brother tracking your every move with the new breed of GPS-enabled cell phones, consider the safety benefits. According to a story reported on the ABC-affiliate in Phoenix, a lost couple’s cell phone may have saved their lives after they got lost in the Sedona desert. The hikers made a call to 911 before activating the GPS in their phone. Rescuers were lead within 200 feet of their position — getting them out of the desert quickly. So, you might want to keep your cell phone with you on your next hike — as long as you are going to be within cell coverage.

Here is a new technology to watch — Geotate from the new GE camera division. GeoTagging allows your camera to capture the GPS location at the same time you take a photo. The problem that has kept GPS out of cameras in the past is that putting a full GPS in a camera takes lots of battery power and increases the cost of the camera significantly. GE has figured out a way to capture the GPS signal, but not implement the hardware to process it. When you upload the photos to your computer, the Geotate software will calculate the location and tag the photos. This is definitely, something to keep an eye on.

Have you ever wanted to take everyone with you on the adventure? Now you can capture it all on video and bring it back to your living room TV. This rugged, waterproof, helmet camera doesn’t even have any cables. The entire trip is captured on an SD card at 640×480 resolution.

If you aren’t convinced that strapping a brace to you leg is a good way to charge your gadgets in the outdoors (See Part I) does an electricity generating fabric sound better? Scientists at the Georgia Institute of Technology have developed a piezoelectric fabric that generates electricity when bent. So, put on your charging pants and plug in the GPS — we are going to the wilds.

Have you ever wondered if all the sweating you do while hiking could be put to better use? Well, the University of British Columbia has developed a leg brace that will charge your gadgets while you hike! Simply strap to your knee, plug in to your rechargeable device, and you will get up to 5 watts with, “Little additional physical effort”. I am not sure about the physical effort, but it sure would be great to have a way to charge up electronic devices in the field.

One of the areas recently improved on Toposhare.org was the detail map interface. Check out Mt. Ralston Peak from yorkie. When you click on the map at the left of the frame, you get a detailed map viewer.  This viewer now is easier to use and has better access to weather maps and aerial photos.  Let is know what you think of the new interface.

Before you run out and purchase a new Magellan Triton, you might want to do a little research on the current product quality. It appears that REI has quietly pulled the Triton due to quality issues. I am betting that the generous REI return policy quickly pointed out the problems with the product. It sounds like the issues are related to firmware issues and missing cables. Buyer beware…

A new version of Windows Mobile OziExplorer was recently released five years after version 1. So, if you have a Windows Mobile device with a GPS (like the new AT&T Tilt or the Trimble Nomad) you can turn it into an offroad navigation machine. The user interface is much improved but the map conversion process is still a big pain to use. They haven’t figured out a way to download maps automatically from TerraServer like Backcountry Navigator does.

If you keep track of new GPS products, you have probably noticed that many new GPS units have a chip-set called SiRF Star III. This new chip-set is supposed to have much better reception under tree cover and in urban canyons. I always question the claims of any new product, so I decide to test it out for myself.

I got two identical devices, one with a SiRF Star II (the old chip-set) and one with the SiRF Star III (the new chip-set). I did a hike of old growth trail where the trees are over 200 years old. I carried both devices so they were in identical conditions.

What I found was amazing! The SiRF Start III product lives up to the hype. If you look at the photo below, you can see that the green track (the new SiRF Star III) follows the road very closely the entire way. By contrast the red track (the old SiRF Star II) wanders up to 100 feet off the road and spends much of its time without a fix (shown by long straight straight lines).

So, if you have an older GPS that is based on the SiRF Star II technology that looses signal under heavy tree cover, it might be time to start looking for a new GPS.
