Sending your location using Google Maps

How to share you location on Google Maps in case you need help (requires an internet connection):
1. Set Google Maps to Google Earth
2. Click on the 3 vertical dots icon in the upper R/H corner
3. Choose "my location"
4. Choose "share"
5. Choose how you'd like to send the location message

It's a good idea when you go out solo or even with others to have someone at home or a friend somewhere who is aware that you 'might' use this feature if there is a problem. In other words, if you're going to use FaceBook Messenger as the potential way to send a help message, make sure your family or friend is aware of this and has it turned on.

Mobile Phone GPS apps

I've downloaded two paid-version navigation apps. One is Backcountry Navigator and the other is GPS Essentials. Both are quite versatile and easy to use. Both offer offline navigation, acting on satellites just like a standard GPS unit (no internet needed)
Backcountry Navigator was 419 Baht (US$12)
GPS Essentials (donation plugin) was 177.96 Baht (US$5)…

I used Backcountry Navigator on an actual route once a couple of days ago. It was easy to use and highly accurate. I checked it against Google Earth when I got home and it was actually more accurate on the placement of the track as it related to the road I was on.

Wild edible plants: Taro nutritional facts

Taro is fairly common in the wild. If not taro, the colocasia family is readily available. The root or corm is the standard part that you eat, though the stems and leaves are also edible. The stems and leaves must be cooked to dissolve the raphides (sharp calcium oxalate crystals). Once dissolved, they are a form of usable calcium.

The root is a very good source of carbs. 100 grams of root contains about 26 grams of carbohydrate. This is about 20% of your daily requirement, so a couple of roots could be equal to about half of your daily carb requirement, which is certainly enough to keep your energy level up and your brain functioning properly.
Taro is a decent source of B-complex vitamins.

Minerals include zinc, magnesium, copper, iron, manganese, and of potassium.
If you eat the leaves, which you should in a survival situation, you can add vitamin C (100 grams provide approximately 80% RDA), Phosphorus, Calcium, and trace amounts of Selenium and other minerals.

In sum, finding a patch of Taro in the wild would go a long way towards enjoying your involuntary camping trip.
