OS Landranger vs OS Explorer maps – selecting the right one for your journey

Ordnance Survey maps are detailed high quality maps of Great Britain and Memory-Map were the first company to licence OS map data to produce digital maps for outdoor recreation. The Memory-Map OS Landranger 1:50,000 and OS Explorer 1:25,000 maps look identical to the printed OS versions – but what are the main differences for users and what are the benefits of each?

The main difference between the two maps is scale; the number of times the map would need to be magnified for it to be actual size (or the number of times that the real world has been reduced in size to become the map).

OS Explorer maps are at 1:25,000 scale, which means every 4cm on the map equals 1km in the real world. These popular maps show great detail including footpaths, rights of way, open access land and even vegetation which is very useful for walking, running, horse riding and off-road cycling. They are an essential for longer or more complex walks or for those going off the beaten track. They’re valuable too when kayaking or climbing. The detail shows every house, public facility or point of interest and provides the tools you need to locate yourself as well as finding the nearest pub after a hard days walk!

OS Landranger maps cover a wider area with a scale of 1:50,000, meaning every 2cm on the map equals 1 km on the ground. Because they cover a larger area than the OS Explorer map, they’re handy for planning a day out over a broader area and for getting a good sense of where you are going. However they don’t contain as much detail as the OS Explorer range, and you lose things like open access land. Footpaths, rights of way and some tourist information still feature on the Landranger maps and they can still be used for walking but are really ideal for days when you are covering longer distances, especially if you are exploring by car or doing road cycling.

Using Memory-Map is the easiest and quickest way to get Ordnance Survey Explorer and Landranger maps onto your PC, iPhone, iPad, or Android device; turning your mobile into an outdoor GPS to make navigation safer, easier and more fun.

 

Got a soggy map? Should have used Toughprint

mmtoon1At Memory-Map we provide the most up-to-date products in the modern mapping and GPS fields, including digital Ordnance Survey maps, marine and aviation charts, and GPS maps for Adventurer and Android.

Some people though are still quite happy to take their printed topographical maps out into the field. Apart from the traditional aesthetics associated with using a paper map, the benefits include the fact they never lose their power source or fail to work because of unreliable service. Paper maps are still an essential back-up when exploring out and about.

For those people that prefer using printed paper for their primary mapping though, experience has shown that maps get damaged out there, especially when the weather is bad. Out in the elements, battling the wind and rain, traditional maps tear at the creases and the paper gets soggy. Some people prefer to keep their traditional maps safe at home and to take copies into the field – expendable copies.

GPS technology has certainly had an impact in mapping, but so too has the technology behind printed mapping. Toughprint waterproof paper is a great example of how old and new can collide in the world of navigation.

Toughprint paper has a micro-porous surface, is suitable for use on colour and mono printers and copiers, and can be printed on both sides. Because the paper is waterproof it is ideal for printing maps for outdoor use as it resists crumples and tears and any collected moisture or dirt can be wiped clean off.

But its uses don’t end with just printing maps. Because it has the capability to hold vibrant colours and make crisp clear high definition photographic prints, Toughprint waterproof paper can also be used to print anything that needs to be outside; from outdoor menus of alfresco restaurants, directional signage for rallies or orienteering events, cataloguing plants and flowers in a garden, on site building engineers, supporters at team events, outdoor market signage and, I suppose, to street protesters.

So if the next time you’re out and about this winter, and you return home with a map in several pieces or just a soggy damp mulch in your pocket, think about investing in a ream of Toughprint waterproof paper before your next journey.

Why do tracklog distance and ascent differ between GPS and mobile apps?

Those of us who have taken to technology to aid us in our navigation and record GPS tracklogs and stats for the routes that we enjoy can now use either a standalone GPS unit or a mobile phone with a GPS app.

However anyone who has used both to record details of a walk will know that the data recorded (for example distance and ascent) is never the same even when used side-by-side on the same walk. We are often asked what it is about GPS that makes this happen?

Well, a GPS is made up of many things including an aerial to receive the signal from the satellites, a chip to process the data once received and then the software to calculate and record position.

Imagine a portable radio as an analogy; they are all designed for receiving the same signal, but the quality of aerial and electronics in your radio makes a huge difference as to whether it will pick up the broadcast and the quality of sound you’ll hear. Similarly every GPS is capable of receiving the same satellite signals but those with better aerials will receive more satellite signals and the more you can receive the more accurate your position.

A good standalone GPS unit will generally have a better aerial and better processing, but mobiles are catching up fast and try different mobile apps to see if the app itself makes a difference. Of course we’d recommend that the Memory-Map app is the first one you should test…so try a FREE Test Drive and compare stats with your own or a friends GPS next time you go for a walk.

We’d love to hear your results!

Dedicated GPS vs Smartphone GPS

TX3 blogGarmin’s Android-based Monterra of 2013 could download apps and do pretty much everything a smartphone could do; except of course make a phone call.

But the waterproof, impact resistant hybrid phone from Memory-Map that makes calls, downloads apps, takes photos, plays music – and works as a dedicated, fully-featured GPS addressed that ‘communication problem.’

The TX3 is a mix of Memory-Map’s mapping know-how, the Android operating system, and hardware from a partner brand called Seals.

The handset comes with mapping for the whole of Britain at either OS Landranger scale 1:50,000 (£299) or Explorer 1:25,000 (£369). Or you can pay £449 for the Platinum package – Streetmap, Landranger and Explorer, together on the same phone.*

In comparison with an iPhone, it’s clear the TX3 has the look and size of a phone rather than a GPS unit, meaning it’s truly pocket-size. But it comes with a waterproof and impact-proof casing and in reality you could use your TX3 as your only smartphone.

It’s probably more likely you’ll keep your regular phone and use the TX3 as your main GPS and ‘back-up’ phone, with a Pay-As-You-Go SIM so you can make phone calls in an emergency. We believe that after several months’ use with the TX3 though, users might switch and make the TX3 their only phone when their main phone contract is up for renewal.

The TX3 uses the excellent Memory-Map functionality, which is exactly the same as you’ll find on the Memory-Map Android app. Using the Android system, the TX3 can also add other apps, take photos and store music, and that’s something to dance about.

Edit and update your maritime charts with Memory-Map

An Admiralty Notice to Mariners (NM) is an update or alteration to a marine chart to ensure that the best information is available for the safe and effective planning and navigation of voyages.

Every year the United Kingdom Hydrographic Office (UKHO) issues over 5,000 NMs which allow mariners to update their charts with the latest safety-critical information.

mmm14_offshore_600_1Each NM is compiled using the same highly reliable data as that used to produce the regular Admiralty nautical charts, and mariners are kept up to date via the weekly online Leisure Notices to Mariners service on the UKHO website: www.ukho.gov.uk/leisure

Many leisure mariners, in believing that “rocks don’t move,” tend to overlook the importance of chart updates. However, changes in buoyage and lights, new wrecks, temporary obstructions or changes in depth to rivers and estuaries are all examples of updates to charts that are critical for safe navigation.

Updating is easy and there is advice on how to do this on the UKHO website, from using pens direct onto the paper charts to the pasting and imposition of colour blocks. The updating of Memory-Map marine charts is just as simple.

First, if you’ve not done so already set the co-ordinates in Memory-Map to display as Lat/Long using the Mode > Position Format > Lat, Long > Deg, Min setting.

Then use the Mark button to place a mark on the screen and drag or edit the properties to put it in the right place. The properties box also allows you to change the name, symbol and add notes.

Finally, we recommend ticking the ‘Locked’ box to lock the mark in position so you don’t then accidentally drag it to the wrong place some time in the future!

Before updating you should determine if the NM is applicable to your chart and vessel. You may decide that it isn’t relevant; for example, changes to a very deep sounding or a new cable in very deep water are not necessarily of interest to the leisure mariner. You should also be aware that NMs are applicable only to current editions and charts, and not past editions.

Be safe on the water this summer with up-to-date nautical charts. The intuitive and easy to use software with Memory-Map digital marine charts can be used on your PC, iPhone, iPad or Android device. The complete folio of over 850 high quality raster charts covering all of the UK, Ireland and the Channel Islands is sourced from data obtained from the UKHO and look identical to the paper charts you use on board.

When it comes to walking, France offers something for everyone

France is a big country so there is loads of good walking to experience. In fact in some regions there is enough to keep you occupied for a whole fortnight’s holiday.

mmFrom taking a gentle stroll through timeless Gascony or the majestic Loire Valley, to easy coastal walking in Brittany or a challenging hike amid the peaks of the Pyrenees, one constant piece of kit you should have with you is an accurate mapping device.

The best walking maps for France are from the mapping agency IGN. Paper versions can usually be bought in local supermarkets, but you can get the new 2015 digital IGN 1:100,000 or 1:25,000 scale maps from Memory-Map. They use intuitive and easy to use software and cover all of France. They can also be used on up to five devices including Windows PC, iPhone, iPad or Android.

They are great for longer walks, road cycling and general leisure use, and show footpaths, bridleways and other rights of way along with thousands of points of interest. If you are looking to explore beautiful river valleys and unspoiled medieval villages, choose the Dordogne or the Tarn. Further south, the allure of Provence, with its lavender fields and sleepy stone hamlets, is hard to beat.

Don’t forget the climate in France is different from Britain so it will be considerably hotter walking in summer and a good hat and sun cream are always advisable. Even in summer however there can be late snow on the higher passes in the Alps and the Pyrenees so it is always worth checking the situation before you head off. You can ring Meteo France from your mobile (3250) for a local forecast including for mountain areas.

Those of you heading off to tour First World War battlefields in France can also view hundreds of detailed original British trench maps from the Somme and other theatres of war from the Memory-Map historical range.

Battle Maps from Memory-Map

The Second Battle of Ypres was fought in the trenches of the Western Front 100 years ago last month. It was the second of five ‘Battles of Ypres’ throughout the war and consisted of six separate engagements beginning with the surprise German gas attack at the Battle of Gravenstafel Ridge. The other five battles were allied counter-attacks trying to regain the ground lost to the Germans; the Battle of St Julien, the Battle of Frezenberg Ridge, the Battle of Bellewaarde Ridge, the Battle of Hooge and the second Attack on Bellewaarde.

The next few years will see many 100 year commemorative anniversaries relating to the First World War as it slowly ground its way towards the Armistice of November 1918. There will be many articles and documentaries presented through print and TV media, but one of the best ways to follow the historical struggle is via battlefield maps and there are 130 original detailed British trench maps available in 1:10,000 scale of the Ypres Salient using Memory-Map software from the Memory-Map website.

The Second Battle of Ypres marked a few firsts too; the mass use by Germany of poison gas on the Western Front and the first time a former colonial force, the 1st Canadian Division, defeated the force of a European power (Germany) on European soil.

The Ypres salient bulged eastward around the town of Ypres, in Belgium. At around 5pm on 22nd April, the German Army released 168 long tons of chlorine gas over a four mile front, on the part of the line held by French Territorial and colonial Moroccan and Algerian troops. (Poison gas had been used first on the Eastern Front at the Battle of Bolimov in Russia three months earlier, but the gas liquefied in the cold and became inert.)

The 5,730 gas cylinders had been brought to the front manually and were opened by hand, relying on the prevailing winds to carry the gas towards enemy lines. Because of the haphazard method of dispersal, a large number of German soldiers were injured or killed in the process of carrying out the attack. The French troops in the path of the gas cloud suffered almost 6,000 casualties, many of whom died within ten minutes of the attack, with many more blinded. The chlorine gas, being denser than air, quickly filled the trenches, forcing the troops to climb out into heavy enemy fire.

By the end of the battle the salient had been compressed and the town itself was closer to the line. It was repeatedly bombarded with observed artillery-fire and gradually demolished.

You can follow the course of the Battle of Ypres and the Western Front by viewing 130 detailed and original British trench maps of the Ypres Salient available from Memory-Map. With Major & Mrs Holt’s Battle Map of the Ypres Salient you can find the locations of engagements and add your own photos and notes directly onto the maps. You can even compare the locations side by side with modern day maps, making it a highly recommended addition to your travelling kit if you are going on a battlefield tour.
