Vertical Aerial Photography Environment Agency Released [Open Data]

noreply@blogger.com (Mapperz) — Wed, 29 Jun 2016 18:32:00 +0000

High Resolution Vertical Aerial photography for England has been released as Open Data from the Environment Agency.

High Resolutions range from 50cm to 10cm (Orthorectified)

Downloaded SU46NE.zip (Newbury) Image showing Vodafone HQ at 20cm Resolution

"Vertical aerial photography is an airborne mapping technique, which measures reflected light in the red, green, blue and near infra-red spectrum. Images of the ground are captured at resolutions between 10cm and 50cm, and ortho-rectified using simultaneous LIDAR and GPS to a high spatial accuracy. The Environment Agency has been capturing vertical aerial photography data regularly since 2006. As of May 2016 we have 750 discrete individual surveys covering approximately 29,000km2, each ranging in coverage from a few square kilometres to hundreds of square kilometres. Historic data are available for some areas where we have carried out repeat surveys. Photography can be captured in all survey conditions, including incident response where it is used to derive flood outlines.

The photography is supplied as a raster dataset in ECW (enhanced compressed wavelet) format as either a true colour (RGB), near infra-red (NIR) or a 4-band (RGBN) dataset. The data are presented as tiles in British National Grid OSGB 1936 projections. Attribution statement: © Environment Agency copyright and/or database right 2016. All rights reserved."

Note all Aerial Imagery is in British National Grid (OSGB36) and in ECW format.
QGIS will open this without plugins (on Windows only) Mac and Linux GIS users need to do more workarounds.

Noise Map (High Speed 2 Rail Impact)

noreply@blogger.com (Mapperz) — Tue, 26 May 2015 19:12:00 +0000

Noise Map (High Speed 2 Rail Impact)

A nice visualization of the impact of potential Noise traveling around the new High Speed Link (known as HS2)

The project to create a faster link from London to Birmingham by rail then expanding to the north of England and to Scotland at later dates.

Noise contours — The contours are based on computer modelling of the equivalent continuous sound level (LpAeq,T) from HS2 during the daytime. They are assessed in 5dB steps down to 40dB. Peak noise levels would be higher, at up to 95dB at 25m from the centre of the tracks. Concerns have been expressed that this means a slightly wider area than shown would perceive noise from HS2 than indicated by these contours.
These contours do not take into account other noise, such as noise from adjacent roads. While that means overall noise levels would be higher where there are other noise sources, noise from HS2 would be less conspicuous compared to places where background noise levels are low. These contours assume trains passing at 360km/h where the design speed allows this, although normally they will operate at 330km/h unless catching up time when running late. Although the contours are shown only for phase 1, they assume the full phase 2 pattern of services of up to 18 trains per hour.

QGIS Ordnance Survey Opendata Cartographic Styles

noreply@blogger.com (Mapperz) — Wed, 18 Jun 2014 14:11:00 +0000

QGIS Ordnance Survey Opendata Styles

Ordnance Survey have released Style Sheets for their #opendata including ESRI (ArcGIS) and Quantum GIS (QGIS) style sheets.

Most strikingly for the Vector Map District Product that is one of the best full Great Britain datasets everyone can download from

https://www.ordnancesurvey.co.uk/
opendatadownload/products.html

Nice looking vector data in QGIS using Vector Map District Data from
Ordnance Survey Opendata.
(Yes motorways in the UK are blue....)
But you can change that if you want.

You can download the stylesheets from

http://www.ordnancesurvey.co.uk/resources/carto-design/
cartographic-stylesheets.html

And Charley Glynn sent me a twitter message that these stylesheets and associated files are available on github here:.

https://github.com/OrdnanceSurvey/OS-VectorMap-District-stylesheets/tree/master/ESRI%20Shapefile%20stylesheets/
QGIS%20stylesheets%20(QML)/Full%20Colour%20style

Couple of notes before the quick guide to help you get going...

Install the font provide first - see quick guide below.

The shapefiles have a classification field that is truncated (shapefile truncates field names) but if change to CLASSIFICA it will work. See this screenshot.

Quick Guide

1. Fork or download the contents of this repository

2. Copy the font file 'OS_VMDistrict.otf' into your systems font directory (on Windows machines this is (C:\Windows\Fonts)

Your machine may require a restart for QGIS to recognise this new font

3. Load your OS VectorMap District ESRI Shapefile data into QGIS

4. Double click on a layer to access the 'Layer Properties' window > click on 'Load Style...' > navigate to the directory containing the QML files (those ending .qml) > select the QML file that corresponds to that layer > click 'Open' > click 'OK'

Repeat step 4 for all layers

5. Although every feature is styled, for use as a contextual map we recommend the following layer order and visibility:

Recommended viewing the map between 1:10,000 and 1:25,000 for maximum legibility

I have even reprojected the data to Web Mercator and got the Bing Aerial Imagery as a background.

Just styles need reversing on a dark background, this uses the Openlayers plugin, the only restriction is making the imagery transparent to 'fade' the imagery down then less contrasting colours can be applied to the background.

The only addition I made was adding the OS Vector Contours from the OS 50 Terrain Dataset - just for a bit more details in the rural areas of England.

Overall it is well worth downloading the styles and playing around with QGIS and the styles.

The FIFA World Cup of Football 1930-2014.

noreply@blogger.com (Mapperz) — Fri, 13 Jun 2014 14:06:00 +0000

The FIFA World Cup of Football 1930-2014.

A great map showing The FIFA World Cup of Football since 1930-2014.

"The national teams of 31 countries advanced through qualification competitions to join host nation Brazil. A total of 64 matches are to be played in 12 cities across Brazil. The first round, or group stage, is thirty-two teams divided into eight groups of four teams. Each group will compete in a round-robin fashion. The teams finishing first and second in each group progress to the knock-out stage. This map will update during the tournament to show results and progress.

For the first time at a World Cup Finals, the games will use goal-line technology to help determine whether balls completely cross the goal-line in the event of a marginal decision. Though FIFA president Sepp Blatter had been a vocal opponent of such technology the disallowed 'goal' scored by Frank Lampard against Germany in the 2010 World Cup became so controversial that moves to introduce technology were inevitable. Had Lampard's goal been awarded, England may very well have gone on to win the game."

The official ball of the 2014 World Cup will be the Adidas Brazuca. The name was selected by a public vote that received responses from more than 1 million Brazilian football fans. It is produced by Adidas, the official FIFA World Cup match ball supplier since 1970.

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

noreply@blogger.com (Mapperz) — Fri, 31 Jan 2014 17:02:00 +0000

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]

noreply@blogger.com (Mapperz) — Fri, 27 Dec 2013 17:32:00 +0000

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]

noreply@blogger.com (Mapperz) — Fri, 20 Dec 2013 15:25:00 +0000

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."
