6. Juli 2012 When editing vector features in a web GIS map one often needs support for precise drawing. Snapping to existing features of external data (using WFS or other vector features) was long available in OpenLayers Editor but it still lacked guide line support. We are pleased to announce that guide lines can now be generated automatically by OpenLayers Editor whilst a feature is drawn.

My colleague Robert Kirkpatrick from Global Pulse has been actively promoting the concept of “ data philanthropy ” within the context of development. Data philanthropy involves companies sharing proprietary datasets for social good. I believe we urgently need big (social) data philanthropy for humanitarian response as well. Disaster-affected communities are increasingly the source of big data, which they generate and share via social media platforms like twitter. Processing this data manually, however, is very time consuming and resource intensive. Indeed, large numbers of digital humanitarian volunteers are often needed to monitor and process user-generated content from disaster-affected communities in near real-time.
Technology :: 60-Second Tech :: December 21, 2012 :: Email :: Print An algorithm can evaluate tweets within the overall Twitter flow to assess their veracity. Larry Greenemeier reports Twitter has become a go-to news source in times of crisis. However, as we learned once again during the Newtown tragedy, inaccurate or even purposefully deceptive tweets can just as easily spread misinformation .
So far, QGIS does not come with many default symbols. Quite often one just needs two or three colors that go well together. That’s why I created a series of simple fill symbols based on ColorBrewer .
The Royal Mail are trialing the use of GPS units to collect more accurate location information as way to broaden their range of income generating services: Something of interest relating to flood modeling. The link below contains an article describing JFlow, a tool that has been used to map the the flood risk for the UK: The following link describes WFS/WFS-T in the context of the aftermath of the Christchurch, NZ, earthquake for the distribution and update of geospatial data between different agencies: <p style="text-align:right;color:#A8A8A8"></p>
Here's the recent geonews in batch mode. On the open source and open data front: On the Esri front:
After my recent accolades on Pearltrees service, I received a comment from a frequent Pearltrees user asking about installing the Bookmarklet to iOS Safari on his iPhone. By following the directions given on the iPad, I was successful at this and want to share. If you use Pearlrees either as a web service or on the iPad, you will see a button entitled “Pearler”. According to the FAQs, here’s what that does: • What is the pearler? The pearler is an extension that allows you to easily and quickly collect web pages directly from your browser.
To depict elements of the topography of a landscape in a symbolic, abstract, geometrically sound but also eventually easily understandable way is a core discipline of cartography. Beneath all topographic elements of a landscape mountains are for sure amongst the most challenging ones to model and depict. Not only the derived geometry needs to fulfill the constraints of allowing a meaningful combination with other map elements but also the applied cartographic design should support the visual impression from the terrain features and especially the most dramatic ones, including the mountains itself. It is therefore not a big surprise that beyond the most famous cartographers you can find especially such which have deserved their merits by designing and producing cartographic mountain depictions of high quality.
Raspbmc is a minimal Linux distribution based on Debian that brings XBMC to your Raspberry Pi. This device has an excellent form factor and enough power to handle media playback, making it an ideal component in a low HTPC setup, yet delivering the same XBMC experience that can be enjoyed on much more costly platforms. Raspbmc is brought to you by the developer of the Crystalbuntu Linux Distribution, which brings XBMC and 1080p decoding to the 1st generation Apple TV. Here’s why you might like Raspbmc:
It's the 2012 Esri International User Conference , expect more Esri news in the coming days, meanwhile, Mandown made me aware of the launch of Esri Maps for Office . Here's the official list of features , and the summary from the Mandown blog: "With Esri Maps for Office, business professionals can quickly create interactive maps from their data in a Microsoft Excel spreadsheet. These live maps, which can be based on any geographic component, such as customer locations or sales by ZIP Code, can be simply added to Microsoft PowerPoint presentations or shared through Esri’s cloud mapping platform, ArcGIS Online. Maps shared through ArcGIS Online can then be distributed throughout an organization or embedded into mobile or web applications." Of course this isn't the first solution to build maps directly from MS Excel , but the first deep integration with MS Office from Esri.
Line charts and area charts are very closely related. They are both good for time series data. They both show continuity across a dataset.
In this round up, we are presenting a very helpful compilation of some free online tools that will help you create charts, diagrams and flowcharts. With the help of charts and graphs, you can display relatively large amount of data in a very concise and self-reliant style. Graphs and charts represent the relationship between two different but interlinked entries.
Stamen’s maps are amongst the most creative and beautiful OpenStreetMap visualizations and it would be great to have them as base maps in QGIS . No problem! Nathaniel Kelso has already done all the work for us and we can download the extended OpenLayers plugin from his Github page . (There is a pull request in place to add Stamen to the default plugin too.)
By the CNN Wire Staff (CNN) – Ugandan authorities did not initially detect an Ebola outbreak because patients weren’t showing typical symptoms of the lethal virus, the nation’s health minister told CNN Sunday. Patients had fevers and were vomiting, but did not show other typical symptoms like hemorrhaging, Health Minister Dr.
