UKFreeTV Creates Freeview Digital Coverage Map

UKFreeTV Creates Freeview Digital Coverage Map (Beta)

Over the last month Mapperz has seen this excellent (though still in beta) Google Map Mashup develop with comments and feedback from users of this free service being acknowledged by the creator.
[which is 100 times better than the official site that can only do postcodes searches but no visualisation]
The site is developed and maintained by @briantist (Brain Butterworth) and well done for taking the time to compile and map UK Digitial TV Coverages which does include Freeview HD coverage.



Yellow is the area where the transmitter provides the best signal, green is where there is overlap and the selected transmitter is not the strongest signal.

Example: http://www.ukfree.tv/transmitters.php?P=RH130TR&s=map

The green/yellow fades to white where the signal is weakest.

Other Features:
The new Freeview prediction system - includes Freeview HD

• Now with any date choice
• Terrain mode (beta) - profile see below
  

Terrian or Profiles of the Transmitters to your choosen location (postcode)

There are five different views

• By direction: this will show the various directions your aerial might point and the services you can receive from the transmitters in that direction
• Received signal strength: this shows the information ordered by signal strength, to help you find the strongest signals.
• By frequency: this lists broadcast frequencies from C21 to C68, showing the services on each. This view can be used to find potential interference or to help with digital region overlap areas.
• Service names: this lists the services that you can receive, each ordered by the strongest signal.
• Transmitter names: and finally an alphabetical list of the transmitters with the services listed by broadcast frequency.

Note Terrain Mode(beta) the diagrams (can take several seconds to generate) below show the terrain between the selected location (postcode) and a number of transmitters. Green is used to denote ground, blue for water, with the transmitter on the right.

The values shown in meters are the height above sea level (for the receiver and transmitter aerials), the value in kilometres is the distance from the transmitter. Also shown as a value in degrees in the bearing, with each block being a kilometre step along the way.

Signal Strength

Users can drill-down to individual channels if required.

Reception requires a line-of-sight between the transmitter and receiver aerial. Distant transmitters will, during periods of Inversion become visible and (unintentionally) they may adversely effect reception.

Geotagging N95 Camera Photos to Google Maps

Geotagging N95 Camera Photos to Google Maps

update 30/04/2007
Ogle Earth reviews Digital Urban's post and ShoZu (more info).

Digital Urban beat Mapperz to it (had done this in practice, honest).


The result Geotagged Photo in Google Maps, Content from Digital Urban.

To do this you will need:
1x N95
1x ShoZu
1x Yahoo/Flickr Account
1x Google Account

So will hand you over for full details

N95 users notes a special additon of ShoZu is coming out for the N95 soon.
"Thanks for your review of ShoZu :-) We're working on a special version for the N95 with a few cosmetic fixes and also the ability to automatically 'wake' the gps antenna without you having to load the Maps app in the background."

We look forward to it.

Canada Adopts Free Model for Map Data

Ordnance Survey take note!
Rationale for charging has gone, says government information expert

"If you've got a computer and a fast connection, you can now download all the maps and satellite pictures you could ever want of Canada. Its government has decided to abandon the charging model that it used until last month for the use of its map data and move to a "free data" model - as being urged for Britain by Technology Guardian's Free Our Data campaign"

What about the copyright of the data?

"Another part of the move loosens the ties on the data - although Canada still uses Crown Copyright, it only asks for acknowledgement of the source. We suspect Canada will see the benefits quite soon. Will the UK follow?"
Source: The Guardian - reported by Charles Arthur

Yes Please -sooner rather than in 50 years (when the map data will be out of copyright) by the time they have unwrapped the red tape from the crown copyright issues.
Free our data!

So if you want Canadian Data - and have plenty of free disk space download from these sources

Bristol - Live Work & Play - Mapped

Live, Work and Play in Bristol


Bristol is one of the ten finalists in the Digital Challenge, a government competition to identify and promote the city who is most digitally inclusive.

With a theme of 'Connecting Bristol' this site is our response to that idea, exploring where people live in the city, where they spend their days and how they like to play. By entering three postcodes, we hope to show the shape of people’s lives across the city.

Explore the map (you can scPublishroll around and zoom in & out using the controls in the top right corner) and click on the white dots to open up information on that position and see who does what where. For example, some people might work where other people play and vice-versa - you can browse through the multiple entries using the numbers.
