According to the following sources, drones cannot fly above the AT corridor and cannot take off from, land in, or be operated from designated wilderness areas. They can fly over designated wilderness areas and the rest of the WMNF (except, of course, the AT)...

A little more info and a video describing his project. https://thehimalayantimes.com/nepal/swiss-machine-ueli-steck-killed-in-mt-everest-accident/ Doug

The article says "speed record", not "speed record for the N Col route". Thus the S Col ascents invalidate the claim. (The article does identify the route, but as noted fails to qualify the claim.) The S Col route basecamp is at 5380m and the N Col route basecamp is at 5180m so the amounts of...

Thanks--this is the one that I was recalling. Doug

IIRC, a Sherpa climbed from the Nepali basecamp to the summit in less than 24hrs a number of years ago. Doug

A moving average filter is a form of low-pass (smoothing) filter. They are a specific use of windowing. https://en.wikipedia.org/wiki/Window_function. Windows are a well-studied tool in signal processing. (My degree specialty is classical signal processing.) I have done some experiments...

That is quite possible, however, such strategies (often used to give the appearance of better accuracy) can decrease accuracy under certain conditions and/or cause other odd behaviors. The inertial sensors also have noise, and like the barometric sensor, it can be difficult-to-impossible to...

All real-world measurements of continuous parameters (such as location and altitude) have noise (errors). You have to learn how to deal with them. Note that long-term averaging of the location or altitude will generally give you a more accurate value than a single measurement. <technical>...

One of the effects of continuous automatic calibration from the GPS is that differences between the standard lapse rate and the current conditions are calibrated out. (This is good for hiking, but has pros and cons for aviation.) I have no idea whether the barometric altimeter (including the...

You can download the track to a GPX file, edit it so it only contains the hike, and then compute the stats. These stats will be less accurate than those computed by the GPS because the GPS has more info available to it than is in the track files. Also, the top speed is a vary iffy...

Actually DougPaul misread the original question and answered a different one. When the GPS is off, autocalibration is disabled--therefore only the barometric sensor is active. There are small variations (likely just noise) in the measured altitude. The ascent and descent numbers are just...

The total climb (or descent) may still be off after autocalibration. (Of course, the altitudes in the recorded track will also be off for the early part of the hike.) By having my GPS on during the drive to the trailhead, I can ensure that it is calibrated at the beginning of the hike. I...

Autocalibration requires the GPS to be turned on. It uses the GPS altitude to continuously calibrate the barometric altimeter. If I leave my GPS on and autocalibrate for my drive 2+ hour drive to the Whites, the indicated altitude at a summit is generally within 10 feet of the published...

You can also get a tick tested on your own: https://www.tickreport.com/ The test covers more pathogens than Lyme. (There are other testing services: https://www.google.com/#q=tick+testing) Note: I have never used this service myself. The link is from...

You might also search for a "cuban hitch camera", "cuban hitch binocular", or a "binocular harness". Don't know if the cuban hitch is still available. Both are aimed at cameras or binoculars a bit heavier than a P&S, but they would probably work well. Doug

Practice by standing in a sunlit spot and aiming a spot of light on a nearby object such as a tree branch or a feature on a building. You should be able to aim the spot at essentially anything within sight. There are two types of signaling mirrors: 2-sided and reflex. * a US Govenment training...

You could put a webbing sling/strap through the loop and carry it bandoleer style. Different from what you are requesting, but it might do the job well enough. Doug

As nartreb noted, we cannot make any specific suggestions without knowing the camera and lens. However, if it is a recent camera, you can look it up at Adorama (http://www.adorama.com/) or B&H (http://www.bhphotovideo.com/) and look under accessories for compatible camera cases. Lowepro is one...

He was also smart enough to place himself in the middle of a slide where he would be visible from the air. And then shine his headlamp at a helicopter. Note: A rescue mirror for signaling to aircraft during the day* can be made from 2 CDROMs/DVDs glued back-to-back. You can use 8cm CDROMs if...

In addition to the difficulty of thinking clearly when under stress, there is also the problem of incomplete trail information. Willett could have decided that returning the way he had come was too risky or continued on his route until he decided to abort and that he should take a different...
