Aerial Maps – A short history (The role of maps during the war)

This August (2014) marks 100 years since the start of the Great War, World War I.  To commemorate this, the National Archives has digitised 1.5 million pages of war diaries, giving readers an insight into what the war was like from a first-hand perspective. We too look back at the technology used during the First World War, specifically the use of Aerial mapping. 

Aerial maps had been around for quite some time before WW1, dating back to the mid-nineteenth century. Gaspard-Felix Tournachon, a French photographer and balloonist, was the first to take an aerial photograph in 1858. The technology soon evolved; in 1882 British Meteorologist E.D.Archibald had pioneered Kite Aerial Photography.
During WW1, Aerial photography had many different uses, and was integral to operations. Aircrafts with cameras attached to them flew overhead taking photos. By the end of the war in 1918, both sides were taking photographs of the front line twice a day. In the same year, General Edmund Allenby commissioned five Australian pilots to photograph 624 square miles in Palestine to improve existing maps of the area – the first use of aerial photography as an aid for cartography.
Aerial maps also branched out to aid with more commercial practices at this time. Several WW1 vets recognised the potential aerial photography had for survey and mapping purposes. A company called Aerofilms created Photogammetry (the science of mapping from photographs), and mapping companies such as the Ordnance Survey started to work with them.

As with WW1, when the Second World War started, aerial mapping technology saw a period of rapid change. Airplanes that were compact and fast were found to be the most suitable aircraft for this activity, particularly Spitfires. Heating systems for cameras and higher altitude photography was also used during this time.
In the present day, it is increasingly likely that radio-controlled planes or multi-rotor helicopters are the aircraft of choice for aerial imagery. Full scale aircrafts still have important roles where higher altitudes or heavier equipment is involved. Aerial maps are now used by individuals on a daily basis, to help them with navigation via smartphone apps.

Aerial maps have also found their place within modern businesses. Many companies require high resolution 12.5cm aerial maps, which allows them to undertake a detailed analysis of the area for planning applications or to combine aerial maps with other data sets, such as height data. .Map by Groundsure sells both 25cm and 12.5cm aerial maps of Great Britain from leading provider, gettmapping.

Risk of Flooding from Surface Water [England & Wales]

Risk of Flooding from Surface Water

Environment Agency release more detailed flood mapping at a time of need.

Ironic that the Environment Agency release this during severe flooding events in England  (and people still without power across 24th, 25th & 26th December 2013).

South East was particularity hit hard, would this Surface Water Map make any different?

"Surface water flooding happens when rainwater does not drain away through the normal drainage systems or soak into the ground, but lies on or flows over the ground instead."

The shading on the map shows the risk of flooding from surface water in this particular [Guildford] area.

Maybe a real-time map with 'peak capacity flow' might be a better direction for the future.

See the Maps with the risk of flooding from the surface water.

Central London Cycle Grid Map [proposed]

Central London Cycle Grid Map [proposed]

"The seven Central London boroughs, the City of London, the Royal Parks, the Canal & River Trust and Transport for London (TfL) today publish for public comment their draft cycle network for Central London, the “Central London Grid.”

“Cycle streets” closed to other traffic, new routes by parks and sixty miles of backstreet “Quietways” are part of the proposed Grid. Many of the new Quietway routes will run parallel to Tube lines or bus routes so that cyclists will know where they go. A “Circle Line Quietway” and a “Victoria Line Quietway” are among the routes published today.

A number of Superhighway and other main-road routes will also form part of the Grid, most fully or semi-separated from traffic (with solid kerbs or traffic wands) where they run on busy roads.

Some one-way streets will be made two-way for cyclists. Intimidating and difficult junctions will be improved. A study will be launched into traffic restrictions on one very busy main road corridor where there is no room for segregation and no Quietway alternative."

Create Your Own Streetview

Create Your Own Streetview

It is now possible to build your own 'streetview' views.
Either using an Android device (photosphere capable) or digital SLR camera images. 

Connect photo spheres (constellations)

By connecting your photo spheres you can create even more immersive, 360° views called constellations. You can choose to add your “constellations” to Google Maps, so people can explore your favorite places on Maps. Keep your constellations private or share them with others on Google Maps or Views.

Step 1: Select photo spheres

  1. Go to Views.
  2. Open your profile page by clicking your photo in the top right.
  3. Your images appear in the right panel and as dots on the map in the left panel. Click Select images.
  4. Manually select the images you want to connect.
  5. Click Connect images.
You’ll see an updated map of the images you selected.
  • Your photo spheres are marked in blue, sequentially with letters.
  • Yellow dots are Street View panoramas.

OpenStreetMap Activities for Typhoon Haiyan (2013)

OpenStreetMap Activities for Typhoon Haiyan (2013)

(Remote Mapping to help emergency organizations) 
Typhoon Haiyan  also known as Typhoon Yolanda, is a tropical cyclone that devastated the Philippines. It first made landfall at Guiuan, Eastern Samar on the morning of November 8, 2013, and then proceeded to Tacloban City , where a storm surge laid waste to much of the area. The typhoon then caused destruction in northern Cebu, Panay island, and northern Palawan before exiting the country towards Vietnam

London Cycling Census Map

London Cycling Census Map

(Data Source: TfL Cycle Traffic Census, April 2013. Data via Andrew Gilligan.)

The London Cycling Census Map is an interactive map showing traffic flows on key corridors in central London. The counts were collected by Transport for London in around 170 locations, in April. TfL released some sample statistics from the dataset in a report published on their website, but the original dataset was not released – however Andrew Gilligan, the Greater London Authority’s cycling commissioner, obtained the data and forward it on to a number of people, including Oliver O'brien, He took the data, consolidated it, and created this map.

So what does the data show?

  • There are several roads where there are more bikes on the streets than any other type of vehicles.
  • Bicycle flow is highly direction, unlike that for most other forms of transport.
  • There are certain routes which are popular with certain kinds of traffic. There are four main east/west corridors in central London. Cars dominate the north most (Euston Road) and the south most (Victoria Embankment) ones. Taxis heavily use Holborn, while cyclists mainly use Old Street/Theobold’s Road. You can see all four of these corridors in the map extract at the top of this article.
  • Equivalent north-south links so less separation of vehicle types.
  • Elephant & Castle remains a complicated junction with large numbers of cyclists and buses, depending on the direction, road and time of day.

QGIS Dufour (2.0.1) New Features

With the release of Quantum 2.0.1 there are some very nice new features.

New Features: (this post does not cover all new features!)

The New Plugin Manager
Easy to see which plugins are compatible with the version you are using.
Red indicates incompatible, though the upgradable option on the left panel will warn you that some older plugins might work.

Oracle Spatial (Direct Support)
One of my favourite things about Quantum GIS 2.0.1 - directly Oracle Spatial  support (no plugins required) comes standard out of the box (ok download).

Selecting Oracle Spatial data

Visual Modeller
Modeller this reminds my of cross between FME Workbench and Model Builder(ArcGIS).
Scripts and Visual dialogues can build up complex models that can be used for many different geoprocessing task, raster/vector conversions. This looks very promising for automated tasks.
 Test models come with QGIS 2.0.1

The Styler has improved vastly you can see that it has evolved into a  quality cartographic tool to control, colour, widths, fills and colour ramps.

"QGIS 2.0 has under gone some radical changes for its upcoming release. Some of these major changes relate to the API"

Please see the full details and code examples here http://nathanw.net/2013/06/13/new-qgis-20-api/

Many, many thanks:
Overall the stability is improved and this release has well worth been the wait. 
Congratulations to all programmers and developers making this a 'production' quality product.

Download this Software today if your are even slightly interested in GIS, Cartographic, Geographic Analysis:

Nokia's map data reveals flow of highway life

Nokia's map data reveals flow of highway life

"Nokia's HERE business is casting bright light on Nokia as a company making use of technologies capable of what it calls "mapping for life," enabling better safety for drivers and better use of information for highway planners. Mapping that is most useful for urban planning takes more than capturing an index of streets and buildings."

"We [Nokia] process billions of GPS probe points per month for our traffic services."

Nokia points out that the data is collected anonymously, using the wisdom of the crowd for enabling real-time updates.
