Free mapping data will elevate flood risk knowledge For the past 17 years we have been capturing LIDAR (Light Detection & Ranging) data in England. LIDAR uses a laser to scan and map the landscape from above and is widely considered to be the best method for collecting very dense and accurate elevation data across the landscape. We use LIDAR to help the work of the Environment Agency in many ways, including creating flood models, assessing coastal change and analysing how land is used.

Several years ago, I created a map of scientific collaborations. The attention this map obtained surpassed my wildest expectations; it got published in the scientific and popular press all around the world! I had mainly forgotten about it until I received an email that rekindled my interest in this visualization and I thought it was high time to revisit this visualization. Unfortunately, scientific papers (and associated data) are closely guarded and only a handful of firms have full access to them.
Population Lines Print I recently produced a map entitled “Population Lines”, which shows population density by latitude. The aim was to achieve a simple and fresh perspective on these well-known data. I have labelled a few key cities for orientation purposes but I’ve left off most of the conventional cartographical adornments. I am really pleased with the end result not least because it resembles Joy Division’s iconic Unknown Pleasures album cover, which in itself is a great example of data visualisation as art. The data, from NASA SEDAC, have been mapped many times before and in many beautiful ways but none seem to me quite as compelling as the simple approach here of using only black and grey lines across the page.
8 tools for visualizing data with open source Data visualization is the mechanism of taking tabular or spatial data and conveying it in a human-friendly and visual way. There are several open source tools that can help you create useful, informative graphs. In this post we will take a look at eight open source, data visualization tools. Datawrapper Datawrapper was created by journalism organizations from Europe, designed to make data visualization easy for news institutes. Transforming Data into Visualization Data visualization explains a story to the user; a story that if told well should help the viewer discern information and relationships between the data. Data visualization, for a designer, is the process of taking a complex structure and breaking it down in a way that the reader can easily comprehend. It is a powerful tool used to translate complex data into accessible insights. In this article, I’ll explain the four critical steps we took to create a visualization graph for the World Economic Forum (WEF).
Data visualization: Science on the map Illustration by the Project Twins When linguist Lauren Gawne roams the valleys of Nepal documenting endangered Tibetan languages, she takes pains to distinguish each dialect's geographical origin. But when it came to producing maps of her results, for many years her cartographic methods were somewhat crude. “My old maps were [made] using MS Paint on top of some copyrighted map that I really shouldn't have been using,” she says. Her next solution wasn't much better: “My mum tracing a map off an atlas so that I had something a bit cleaner to work with.” The one after that — “using Google Earth and dropping pins on it” — was generic, ugly and “looks horrible in a PowerPoint”.
The “Rules” of Data Visualization Get an Update Geoff McGhee is a journalist and data visualizer at Stanford University’s Bill Lane Center for the American West. Data Points is a new series where we explore the world of data visualization, information graphics, and cartography. In the past decade, computer-aided data visualization has migrated from the halls of science and academia into journalism, marketing, political discourse, and many other parts of everyday life. A lively conversation has developed online about data visualization, with blogs and social media accounts devoted to critiquing them. The Antiquities Coalition Site - Culture Under Threat Map LAYER: Areas Under Threat or Control of Terror Groups What it Displays: A heat map of areas that are under the direct control of terrorist groups or threatened by areas they have occupied between January and October 2015. Information from no earlier than 2015 was included due to the continually shifting nature of the MENA conflicts. The terrorist groups included in this map were based on terror groups as defined by the National Counterterrorism Center. Sources of Information: Institute for Study of War (ISW), the Carter Center Syrian Conflict Mapping Project, National Counterterrorism Center and international media reports on terror-controlled territories. LAYER: Heritage Sites Attacked, Targeted, or Destroyed
Presenting gvSIG Online: the solution for Spatial Data Infrastructures on Open Source software During the last International gvSIG Conference a new product added to the gvSIG Association catalogue was presented for the first time. We think it will be well received because it meets an every time more and more need to have a solution for implementing Spatial Data Infrastructures, using open source software and reducing implementation costs of the current market alternatives. gvSIG Online is result of the experience accumulated by the gvSIG Association at the Spatial Data Infrastructure projects implementation of all types and in any sector, from petrol companies to local administrations. But, what is gvSIG Online? We can define the product in a few lines… “gvSIG Online is an integral platform for the Spatial Data Infrastructure (SDI) implementation, 100% open source software.
