GIS Stack Exchange is Open to All

 GIS Stack Exchange is Open to All - New!

A place where you can post a question and get fast answers.
Wiki cross Digg approach. Using Tags and forum based content.
Any 'geo' question

What kind of questions can I ask here?

GIS Stack Exchange Answering GIS Questions 

from the FAQ:
GIS - Stack Exchange is for programmers, DBAs, Cartographers, Geographers and anyone interested in GIS professionally.
Please do look around to see if your question has already been asked (and maybe even answered!) before you ask.

What kind of questions should I not ask here?

Avoid asking questions that are subjective, argumentative, or require extended discussion. This is not a discussion board, this is a place for questions that can be answered!
If you want to talk about the site itself, please don't do it here. Visit the meta-discussion site where you can talk about things like what questions are appropriate, what tags we should use, suggest a feature, or generally discuss how GIS - Stack Exchange  works.

Be nice.

Treat others with the same respect you'd want them to treat you. We're all here to learn together. Be tolerant of others who may not know everything you know. Bring your sense of humor.

Be honest.

Above all, be honest. If you see misinformation, vote it down. Insert comments indicating what, specifically, is wrong. Even better — edit and improve the information! Provide stronger, faster, superior answers of your own!

The UK SoundMap Beta - British Library

UK SoundMap starts with a pilot survey based on the Sheffield metropolitan area. The national survey will follow later in 2010. 
The UK SoundMap Beta - British Library

Make sure Location Services in Settings/General is switched on. Otherwise you can edit your recording on Audioboo FM and add a location by placing the microphone icon on the map at the place where you made the recording

How can I take part?

If you can make recordings in any location within the Sheffield area, please record your surroundings, describe them with tags and comments, then upload the recordings to our map. From there, a permanent public record of everyday sounds - the UK SoundMap - will be made accessible to everyone, while being stored at the British Library and made available to soundscape experts.

Want to add your sounds to the map then follow these steps;

  1. register with AudioBoo
  2. record & publish
  3. listen to soundscapes

Ways to record and publish

There are two ways. The easiest way is to use a smartphone. Alternatively you can use a web browser.

Listen to soundscapes

Once uploaded, your recordings will be found easily as locations on the soundmap and searchable by tags. Please allow 48 hours for your recordings to appear on UKSoundMap. You can meanwhile check your recordings right away on AudioBoo.fm

  • Just record your everyday surroundings.
  • What do your home, leisure and work environments sound like?

    • What sounds define these places and how do they make you feel? Some may be restful, some unpleasant - let us know why.
  • Does the sound of these places differ during the day?

    • What are the differences? Let us know what these sounds mean to you.
  • Where are the noisiest or quietest parts of your locality?

    • What makes it so noisy? What can be heard even when it's quiet?
  • Make as many recordings as you like at different locations and times.
  • Each recording may be up to 5 minutes long.

    ESRI Shapefile - HTML5 Viewer

    ESRI Shapefile - HTML5 Viewer

    This is a neat way to display ESRI Shapefiles online without using any GIS software.
    (Note: Not compatible with Internet Explorer)
    Shapefile HTML Viewer loaded
    Two shapefiles are displayed here cities of the world and associated text along with Countries of the World with a line style and  polygon fill style.

    Notes: Keep shapefiles as small as possible, smaller shapefiles returns faster display results.
    Faster than ArcIMS in some cases. But depends on the hosting server.

    Shapefile HTML Viewer Mapperz
    Mapperz Version, styles and fills changed, though seems slower, compare the difference.

    The two files required are the .shp (geometry in lat/lng WGS84) and the .dbf (Table)
    var map = new Map('map', [
        // country shapes
        new Layer('http://mapperz.110mb.com/shape/110m_admin_0_countries', 
    { fillStyle: '#76e97c', strokeStyle: '#18841D', lineWidth: '0.5' }),
        // dots for cities
        new Layer('http://mapperz.110mb.com/shape/110m_populated_places',
     { fillStyle: '#8A2BE2', /*textHalo: '3', textStroke: 'white',*/ textFill: 'rgba(255, 0, 0, 0.6)', 
    textProp: 'Name', font: 'bold 9px sans-serif' })
      Links [source code:]

    More complex version involves 10 shapefile layers.

    MapQuest Open (Beta) Using Open Street Map Data

    MapQuest Open (Beta) Using Open Street Map Data

    MapQuest Open Beta Open Street Map Data and Routes
    MapQuest have over the past few months vastly improved the map user interface and are one of the first major mapping service to engage and encourage the use of Open Street Map Data with the new MapQuest Open mapping project.

    "At the 4th annual international State of the Map 2010 conference, their plan to be the first major mapping site to embrace and encourage open source mapping at scale.  As part of this initiative, MapQuest just launched their first site that is completely powered by open source data from OpenStreetMap.org"

    "This new project – open.mapquest.co.uk – was developed using the new MapQuest.com design but using data provided by the OpenStreetMap community.  The main difference between this new site and our existing MapQuest UK site is that the mapping and routing data was created, edited and enhanced by every day people like you.  OpenStreetMap was designed to give the local community the ability to update areas (roads, parks, hiking trails, bike paths, points of interest, etc) that they know in their own neighborhood and around the world, ultimately leading to what we believe will be the best and most accurate mapping experience for all.

    AOL (owners of Mapquest) also announced a $1 million open-source mapping investment fund.  This fund will support the growth of open-source mapping in the United States in the local communities that Patch.com covers.  More information about the AOL grant application process is available by emailing osm@mapquest.com."

    View the new Mapping Service - http://open.mapquest.co.uk/

    More information - http://blog.mapquest.com/2010/07/09/mapquest-opens-up/
    Well done to Mapquest for taking the challenge on and implementing a clean and easy to use mapping service.

    Climate Change Impact Using Google Earth

    Climate Change Impact Using Google Earth

    The Google Earth KML shows how the world would be affected by a global average temperature increase of 4 Degrees Celsius is an awareness in climate science.

    Using Google Earth this illustrates rising levels of sea water and reduction in crop yields in different parts of the globe if temperatures are not stemmed by reducing greenhouse gases.

    Climate Change Impact Using Google Earth

    The launch of the map by the Foreign Office (FCO) and the Department of Energy and Climate Change (Decc) comes in the wake of the "climategate" row over emails stolen from the University of East Anglia's Climatic Research Unit and the sustained attack it prompted on scientific research into man-made global warming.

    On 14th July, the FCO and DECC launched an interactive map showing some of the possible impacts of a global temperature rise of 4 degrees Celsius above pre-industrial times. It underlines why the UK Government and other countries believe we must keep global warming to 2 degrees Celsius. The map includes videos from the contributing scientists, led by the Met Office Hadley Centre, talking about their research. It also includes examples of what the FCO and British Council are doing to build understanding globally of the urgent need for all countries to accelerate the transition to a low carbon economy.


    Government chief scientist Professor John Beddington said there was "no doubt there is a problem in public confidence in climate change".

    Between November last year and February this year, the number of people who thought climate change was not happening had increased and the number who thought it was man-made had fallen.

    The map, which will be updated as new data becomes available, features videos of scientists talking about the research behind the potential impacts of climate change and information about work undertaken by the Foreign Office and British Council.

    Climate change minister Greg Barker said politicians had a responsibility to help make it easy for people to take action on climate changes.

    And he said: "A lot of this is about the tone - there was a slight sense the climate community, and politicians are a large part of that, got what was coming to it.

    "It was being a little too preachy, had a little bit of a high moral tone."

    He said people did not need to deal in absolutes to make a strong case for action on climate change and it was in the UK's long-term interest to lead the way on the move to a low carbon economy.

    Ed Parsons from Google said: "This is a great example of the benefits of using the latest web technology to visualise scientific information and promote better understanding of the potential impacts of climate change."

    The online map is available, for people who have Google Earth installed, at: http://www.fco.gov.uk/google-earth-4degrees.kml
