Resuming Geonews Aggregation in a Week

Fri, 01/13/2012 - 13:50

Dear users, a short note to let you know I'll be unavailable (and away from computers!) for the next 10 days. Geonews aggregation will resume on the week of January 23rd. I had the intention of publishing more this week, but good intentions are sometimes not enough. Rest reassured, I will include everything pertinent that I accumulated and which was published during the past weeks. Meanwhile, you can still contribute stories that other editors will handle. Thank you for your understanding and patience.

Microsoft Patents Bad Neighborhood Detection via GPS for Pedestrians

Sun, 01/08/2012 - 15:33

Or for geospatial purists, via 'satellite navigation systems' for pedestrian. In any case, Slashdot discusses a story named Microsoft Patents Bad Neighborhood Detection.

Their summary: "With the grant of their US Patent #8090532 Microsoft may be attempting to corner the market on GPS systems for use by pedestrians, or they may have opened a fertile ground for discrimination lawsuits. ... Described as a patent on pedestrian route production, the patent describes a two-way system of building navigation devices targeted at people who are not in vehicles, but still require the use of such a device to most efficiently route to their destination. ... For example, the user inputs their destination and any constraints or requirements they might have, such as a wheelchair accessible route, types of terrain they are willing to cross, the option of public transportation, and a way point such as the nearest Starbucks on the route. Any previously configured preferences are also considered, such as avoiding neighborhoods that exceed a certain threshold of violent crime statistics (hence the description of this as the 'avoid bad neighborhoods' patent), fastest route, most scenic, etc."

Fri, 01/06/2012 - 11:51

Via @Thierry_G I learned about this world map of geospatial conferences to be held in 2012 provided by Quarry One Eleven. You can filter the conferences by month.

I know VerySpatial provide a calendar of geospatial events (compatible with the iCal standard) since 2006.

Anyone's aware of similar global calendars of geospatial events?

Shopping Center Tracking System Condemned by Civil Rights Campaigners

Fri, 01/06/2012 - 11:33

Slashdot is discussing a story named Shopping Center Tracking System Condemned by Civil Rights Campaigners.

Their summary: "Civil rights campaigners have spoken out against a technology used by several shopping centers in the UK to track consumers using their mobile signals. The shopping centers claim that the technology helps them provide better services to consumers and retailers without compromising privacy. The system, called the Footpath, allows them to know how people are spending time in a shopping center, which spots they visit the most and even the route they take while walking around. Several consumer and civil rights groups, including Big Brother Watch, say consumers must be given a choice on whether they want their movement tracked or not."

Extending GIS into data management: more 3D on free geoscience dataset

Fri, 01/06/2012 - 08:53

Bloggage update: Free geosciences 3D data show GIS helping model reservoir depletion, and displaying it on the desktop and on-line. Then came pipeline routing and now to close the loop is gridding and contouring. Again, this is no replacement for geosciences packages, but rather a tool for triage. [...] Starting with ArcMap 9, 3D Analyst extension under “spline with barriers”  handles grids with faults like we do in petroleum, no small thanks to “the two Steves”, Kopp of Esri and Zoraster ex of Zycor. I posted on Arcgis Online the project resulting from this workflow. [...] Beyond traditional visualisation, GIS is thus also used for data management. Next posts will further extend the workflow into data connection and acquisition on and off the web.

Sat-Nav Problem Summit

Fri, 01/06/2012 - 05:29

A local transport summit is being organized in the UK to look at better and more frequent ways to update the information used by Sat-Nav units (http://www.bbc.co.uk/news/uk-16434183). This is to try to avoid those commonly occurring stories that appear in the media such as large vehicles being sent through narrow streets (http://www.bbc.co.uk/news/uk-15395200) or sent along inappropriate roads (http://www.dailymail.co.uk/news/article-1315762/White-van-man-airlifted-safety-satnav-sends-mountain.html).

Best wall map in the U. S. A.

Fri, 01/06/2012 - 00:23

Slate magazine has an article on the "Best of Show" at the 38th annual competition of the Cartography and Geographic Information Society. David Imus spent two years drawing a wall map of the United States, placing special emphasis on relief shading and type placement. The article describes the lengthy design and production process and compares the winning map to the standard National Geographic wall map, illustrated by a few specific examples from each map.

The author, Seth Stevenson, also discusses the advantages of a full national map on paper versus a zoomed-in section of a virtual web map on a screen, stating that children's geographic knowledge is not improving even with easy access to digital maps.

U.S. Judge Doesn't Care About Supreme Court GPS Case

Wed, 01/04/2012 - 13:27

First, happy 2012 to everyone! :-)

Slashdot is running a discussion named Judge Doesn't Care About Supreme Court GPS Case.

Their summary: "The Supreme Court is currently deciding whether or not law enforcement needs a warrant before they put a GPS tracker on a person's car. A judge in St. Louis doesn't seem to care about that, though. He ruled last week (PDF) that the FBI didn't need a warrant to track the car of a state employee they suspected was collecting a paycheck without actually going to work. (Their suspicions were confirmed.) While in favor of corrupt government employees being caught, it's a bit disturbing that a federal judge would decide a warrant wasn't needed while the Supreme Court has said the issue is unclear."

China Begins Using New Global Positioning Satellites

Wed, 12/28/2011 - 17:37

Slashdot discussed this story named China Begins Using New Global Positioning Satellites.

Their summary: "cswilly writes with the news that China's satellite navigation system, called Beidou, has been successfully activated. "With ten satellites now, 16 in 2012, and 35 in 2020, China is making damn sure they are independent of the U.S. military's lock on GPS. According to the article, 'Beidou, or 'Big Dipper,' would cover most parts of the Asia Pacific by next year and then the world by 2020.'" The BBC also has slightly more detailed coverage"

We started talking about Beidou in 2006, sometimes under the Compass name.

Crowdsourcing, citizen sensing and Sensor Web technologies for public and environmental health surveillance and crisis management: trends, OGC standards and application examples

Sun, 12/25/2011 - 10:19

An in-depth review entitled 'Crowdsourcing, citizen sensing and Sensor Web technologies for public and environmental health surveillance and crisis management: trends, OGC standards and application examples' has just been published in International Journal of Health Geographics (http://www.ij-healthgeographics.com/content/10/1/67/abstract). This state-of-the-art review was written by nine world-class experts in the field from a number of distinguished institutions from around the world such as ISPRS, DERI, MIT, etc. And best of all it is Open Access, meaning the full text is free for anyone to download. Below is the abstract and link to download the paper:

Abstract: 'Wikification of GIS by the masses' is a phrase-term first coined by Kamel Boulos in 2005, two years earlier than Goodchild's term 'Volunteered Geographic Information'. Six years later (2005-2011), OpenStreetMap and Google Earth (GE) are now full-fledged, crowdsourced 'Wikipedias of the Earth' par excellence, with millions of users contributing their own layers to GE, attaching photos, videos, notes and even 3-D (three dimensional) models to locations in GE. From using Twitter in participatory sensing and bicycle-mounted sensors in pervasive environmental sensing, to creating a 100,000-sensor geo-mashup using Semantic Web technology, to the 3-D visualisation of indoor and outdoor surveillance data in real-time and the development of next-generation, collaborative natural user interfaces that will power the spatially-enabled public health and emergency situation rooms of the future, where sensor data and citizen reports can be triaged and acted upon in real-time by distributed teams of professionals, this paper offers a comprehensive state-of-the-art review of the overlapping domains of the Sensor Web, citizen sensing and 'human-in-the-loop sensing' in the era of the Mobile and Social Web, and the roles these domains can play in environmental and public health surveillance and crisis/disaster informatics. We provide an in-depth review of the key issues and trends in these areas, the challenges faced when reasoning and making decisions with real-time crowdsourced data (such as issues of information overload, "noise", misinformation, bias and trust), the core technologies and Open Geospatial Consortium (OGC) standards involved (Sensor Web Enablement and Open GeoSMS), as well as a few outstanding project implementation examples from around the world.

Santa's voyage if he used global population ranking to plan his route

Sat, 12/24/2011 - 04:19

In the spirit of the holidays, the GeoTime Team decided to look at what Santa’s yearly voyage would look like if he planned his route based population. This way, he would offload as much weight as possible early in his voyage, thus being more fuel efficient overall. Take a look at the visualization of Santa's December 25th voyage on the GeoTime(s) Blog:

Open Source 'Google Vector Layers' Project

Wed, 12/21/2011 - 17:58

Mapperz made me aware of the open source Google Vector Layers project, allowing you to overlay your data over Google Maps.

Here's what it is: "Google Vector Layers allows you to easily add one or more vector layers from a number of different geo web services to a Google Maps API based application. Currently there's support for ArcGIS Server, Arc2Earth, GeoIQ and CartoDB with more planned."

​And how it's done: "Google Vector Layers works by listening to map events (pan and zoom) and then fetching features within the map bounds after each event. This method works great for data sets with lots of features that you want to interact with, but not load all at once."

There's demos if you want to try it live.

Open Source jQuery Plugin for Creating Subway-style Map Visualizations

Mon, 12/19/2011 - 14:06

Via O'Reilly I learned about this open source jQuery Plugin for creating subway-style map visualizations directly in HTML5. Now at version 0.5.0, the subwayMap Plugin already creates nice maps.

The intro of the provided step-by-step guide: "Here is a guide to using the Subway Map Visualization jQuery Plugin. Before you get started, there’s one thing you’ll want to keep in mind — beautiful subway maps are never automatic; they are almost always the result of care in design and placement to ensure that the resulting map is functional, legible and beautiful. This plugin is just a tool…you will still need to plan and design your map in order to produce a good result."

Google Outlines AI-Based Number Reading For Street View Photos

Mon, 12/19/2011 - 12:41

Slashdot discusses a story named Google Outlines AI-Based Number Reading For Street View Photos.

Their summary: "recent Google research paper [pdf] outlines how it might use AI to read digits in natural images — specifically Street View photos. The idea is to automatically extract the number of each house as captured by Street View and then use this to improve the geocoding data returned by Google. When you next ask for directions to a particular address the new data could be used to show you a street view looking directly at the house you specified."

We mentioned a few times in the past the reading and mapping of license plates.

US Sentinel Drone Fooled Into Landing With GPS Spoofing

Thu, 12/15/2011 - 18:48

Slashdot discusses a story named US Sentinel Drone Fooled Into Landing With GPS Spoofing.

Their summary: "Following up on the earlier Slashdot story, the Christian Science Monitor now reports that GPS spoofing was used to get the RQ-170 Sentinel Drone to land in Iran. According to an Iranian engineer quoted in the article, 'By putting noise [jamming] on the communications, you force the bird into autopilot. This is where the bird loses its brain.' Apparently, once it loses its brain, the bird relies on GPS signals to get home. By spoofing GPS, Iranian Engineers were able to get the drone to 'land on its own where we wanted it to, without having to crack the remote-control signals and communications.'"
