CAD-like Feature Construction with the OpenLayers Editor | geops.de. 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. On many occasions one needs to align new features to existing features in cadastral mapping applications. We did now extend OpenLayers Editor's capabilities by supporting guide lines including snapping on a recent hack day.
Following the angles of an existing feature. In addition it is often required to draw right angles. Placing a vertex using guides to archive perfect right angles. Technically, the system which drives the guide lines and guide points is flexible enough to use parallel drawing and orthogonal drawing at the same time. Automated WMS Testing with Python. Big Data Philanthropy for Humanitarian Response. 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. Meanwhile, companies like Crimson Hexagon, Geofeedia, NetBase, Netvibes, RecordedFuture and Social Flow are defining the cutting edge of automated methods for media monitoring and analysis.

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.
Participants of the 8th ICA Mountain Cartography Workshop. About. Raspbmc is a minimal Linux distribution based on Debian that brings XBMC to your Raspberry Pi.

Esri Maps for Microsoft Office Launched. The Fine Line In a Gray Area: When to Use Line vs Area Charts. Line charts and area charts are very closely related. They are both good for time series data. They both show continuity across a dataset. They are both good for seeing trends rather than individual values. But they can’t always be used interchangeably, as they do have a few subtle — but important — differences. Line charts are good at showing multiple different series and comparing them against each other.
Area charts are not as good at comparing between that many areas because they have problems with occlusion. These differences are mainly due to one simple change. Because of this potential for occlusion, one frequent thing to do with area charts is to stack them. There are two different ways to show this part to whole relationship, as well. Another, more subtle thing area charts can communicate is cumulativity.
If used carefully, the interplay between rates and quantity can be represented very well with a combination line and area chart. 22 Useful Free Tools For Creating Charts, Diagrams and Flowcharts. 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 graphs, flowcharts, diagrams and charts, 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. They are especially helpful for the websites that want to display the difference between their different kinds of services and products.
Charts help the persons to compare two products and services on the basis on their features. Therefore, here we present some free online tools for you.

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.) Simply unpack the plugin into QGIS’ plugin folder. As you can see in the following screen shot, I’ve put it besides the “original” OpenLayers 0.6.2 plugin. It adds the possibility to load Stamen’s Watercolor, Toner and Terrain tiles into the QGIS project: Like all other OpenLayers layers, these can now be overlaid with more data such as this heatmap which is based on Twitter data I presented in a previous post, processed using Heatmap plugin and semi-transparently overlaid onto Stamen’s Toner map: Like this: Like Loading... Manifesto for Agile Software Development. Ugandan officials face Ebola outbreak. 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. Christine Ondoa said. A team from the Centers for Disease Control and Prevention was on the way to Uganda to provide laboratory support to officials dealing with the virus, which health authorities say has left at least 14 people dead in the east African nation this month. A medic who was treating victims is among the dead, Ondoa said. Officials are trying to determine the extent of the outbreak, CDC spokesman Tom Skinner said Sunday.
About five people from the Atlanta-based centers were expected to join a group of CDC staffers who are permanently based in Uganda, Skinner said. A total of 20 cases of the virus have been recorded, officials said Saturday. How to use FF Chartwell. Primarily suitable for Adobe Creative Suite, FF Chartwell for print uses OpenType ligatures to transform strings of numbers automatically into charts. The data remains in a text box, allowing for easy updates and styling. It’s really simple to use; you just type a series of numbers like: ‘10+13+37+40’, turn on Stylistic Alternates or Stylistic Set 1 and a graph is automatically created. To help get you started using FF Chartwell we’ve created this video tutorial and here are some simple steps: ONE — Firstly always make sure the letter spacing is set to “0” (zero) TWO — Using the values 0-100, type the values, then use “+” to combine them into one chart. THREE — Want to bring a bit of color to your work? FOUR — Turn on Stylistic Alternates or Stylistic Set 1 and enjoy!
To see the original data all you need to do is turn off Stylistic Set or Stylistic Alternates. The best local SIM cards in Europe. Donald Strachan replies If you only want to make a few calls and send the odd text, it is usually not worth changing your UK SIM. For example, O2’s standard rates are 24p per minute to call, and 7p to text if you use your phone in France. That’s cheaper than many domestic networks. It is another story with data, however. The cap on data prices is due to fall again on July 1, to €0.20/17p per megabyte (Mb), but local deals are much cheaper.
So, as long as your phone is unlocked (check before you go), it may pay to buy a local SIM. In Italy, TIM (tim.it) and Vodafone (vodafone.it) offer the best coverage. Vodafone (vodafone.es) has the SMART 12 package, with 1 Gb of internet, 60 texts and an hour of talktime. In France data is much cheaper with a prepaid SIM (a carte prépayée sans engagement). Turkey is outside the regulated EU zone. Pretty much anywhere, a new local SIM costs only nominal fee, and comes with a small amount of call credit pre-loaded onto the card.
Ask the experts. Should patients be able to control their own records? Giving patients control of their medical records may sound scary to many doctors, but it could reduce workload and improve outcomes, Peter Davies reports Every general practice in England will have to offer patients online access to their care records by 2015, according to the government’s information strategy for the NHS published in May.1 Currently only 1% do so. As the Department of Health acknowledges, this represents “a challenge to the culture and practices of some health and care organisations and professionals.” But advocates of patient access to records now want to go further. They want patients to control their records, with the right to decide who may access them. As the information record is about the patient, the record is his or her property, they argue.
This may sound counterintuitive to many doctors. Records could contain information that might alarm or even harm a patient, they respond. Projects under way in the NHS are exploring possibilities. Enhanced Messaging for the Emergency Response Sector (EMERSE) My colleague Andrea Tapia and her team at PennState University have developed an interesting iPhone application designed to support humanitarian response. This application is part of their EMERSE project: Enhanced Messaging for the Emergency Response Sector.
The other components of EMERSE include a Twitter crawler, automatic classification and machine learning. The rationale for this important, applied research? “Social media used around crises involves self-organizing behavior that can produce accurate results, often in advance of official communications. This allows affected population to send tweets or text messages, and hence, make them heard. The ability to classify tweets and text messages automatically, together with the ability to deliver the relevant information to the appropriate personnel are essential for enabling the personnel to timely and efficiently work to address the most urgent needs, and to understand the emergency situation better” (Caragea et al., 2011).
