What is a GPX file?

GPX file sampleIn any discussion of routes, navigation or GPS devices, you have probably seen people mentioning ‘GPX files’. GPX is shorthand for GPS eXchange Format and is a type of file that’s really helpful to anyone who loves the outdoors, and is the most popular way of saving and exchanging routes.

What’s in a GPX file?

You can actually open a GPX file in any text editor, and you’ll get something like the image here. While this looks complex, all most people need to know is that it is a list of precise locations, in order, that make a up a route for walking, running, cycling or any other activity. This route can then be placed on top of a map for printing or following on screen.

How to plan a scavenger hunt

Finding a GeocacheFrom geocaching to Easter egg hunts around the house for the kids, we love a scavenger hunt. These games have everything: you have to be quick on the mental draw; you get a bit of exercise when you race from point to point, and you get to satisfy your competitive nature by being the first to collect all items being hunted.

A great scavenger hunt can provide hours of entertainment, improve team-work skills and get you out and about in nature, yet they don’t require much more than a well-thought-out plan. Here are a few tips to help you plan your own… Read More


How are our paper maps evolving?

The future of paper maps has been the subject of lively debate in recent months. Interestingly, while the popularity of GPS devices and mapping apps for mobile devices continues to grow, paper maps are still being used by millions of outdoor enthusiasts every year, who are increasingly looking to access both paper and digital mapping for their activities.

That’s why for a number of years we’ve been looking to bring paper and digital mapping together in convenient ways that suit your activities and uses. For this reason, we’re launching a new series of maps called OS Explorer Map +, which include the same high quality mapping you’ve come to expect from our paper maps, but are printed on a more robust, weather-resistant paper and come with a free 14 day trial subscription to our online mapping application, OS getamap.

Will the GPS replace the compass?

Guest post by Andrew of Outdoor Look.

compass and gps on a mapFor hundreds, if not thousands of years man has explored his surroundings with a compass and maps. Now we see GPS units and apps for smart phones available a plenty, so has the humble compass had its day? Both have their fans with some seeing the GPS as just the latest ‘boys toy’ with lots of buttons and flashing lights and those who see it as a valuable aid to navigating your route that anyone who is serious about walking and hiking must have with them at all times. I lean towards the compass and map, simply because that is how I was taught, but I can see how technology changes and obviously a GPS unit doesn’t take up as much space, but is one better than the other? Let’s see.

A beginner’s guide to geocaching

A beginner's guide to geocachingMany of us have fond memories of exciting treasure hunts as children, with Easter eggs and other small treats often the subjects of our searches. These days, though, it’s much more normal to find youngsters glued to their television screens, completing quests of a more virtual nature. Technology has certainly affected the ways in which people explore the world and enjoy themselves, but it’d be wrong to assume that old and new can’t be combined to great effect. Geocaching is a fantastic example of this. Read More


Walking with a GPS

Handheld GPS DeviceA Global Positioning Device or GPS is a very handy tool for walkers who want the security of knowing their exact location. If you’re walking somewhere relatively featureless then a GPS provides the peace of mind that you’re going in the right direction. It will also allow you to give the emergency services your exact location, should you get in a spot of bother and need their support. Read More


Are you a social hiker?

How and why I use Social Hiking

I was always a keen hiker. Mum used to take us youth hostelling as kids and though University I was a very active member of the hiking club there. I took some steps to ‘go pro’ and started down the qualification route for mountain leadership, but rapidly realised that I would be better earning my pounds elsewhere and keeping hiking as a hobby. After finishing University, I kept in touch with my hiking buddies and we got together regularly, certainly throughout my 20s. As for most people, life took over. My career, other activities, relationships etc meant that hiking became something that happened less and less frequently.

In 2009, I bought my first proper smartphone – a HTC Hero. It wasn’t the earliest Android phone, but as the first of my friends to get one, I felt like an early-adopter. Having a smartphone opened up a huge range of opportunities to do other things with it, other than just basic calls and texts.

In 2010, I changed jobs. I had been the ‘Training Manager’ for national government agency, which meant working away from home most of the time. I moved back into an operational role near home, working shifts and sleeping in my own bed every night (or day depending on the shift!). This gave me a lot more time to pick up on old hobbies. I started hiking again. I started running again. In both cases, due to my shift pattern I was doing it on my own, mid-week with my smartphone, I started tracking my activities, both for safety and to see later how much I’d done.

How do we survey the changing face of Britain?

One of our surveyors at head office

Keeping the master map of Great Britain up-to-date is no easy task and sees thousands of changes a day made to our database. We capture these changes on the ground through our team of 240 surveyors equipped with the latest positioning technology and via Remote Sensing, with both our own Flying Unit and strategic suppliers capturing aerial imagery which is then processed back at head office.

The latest technology makes the task of capturing change on the ground faster than ever before. Our surveyors are usually home-workers and keep the GI data up to date within a set area. They work on a Panasonic Toughbook – a ruggedised convertible notebook computer which serves as both their laptop and data collection tool. It’s both showerproof and dustproof which is essential for a job largely carried out in the great outdoors. It connects wirelessly to their GNSS equipment, electronic total station and hand-held laser rangefinder. It’s also the means for them to connect to head office, arrange and order data for jobs and send data back again.
