Geo-Wiki.org: Validating Global Land Cover with Crowdsourcing

jeu 09-02-2012

The AGISRS list made me aware of Geo-Wiki.org, a crowdsourcing effort aimed at validating global land cover.

From their main page: "The Geo-Wiki Project is a global network of volunteers who wish to help improve the quality of global land cover maps. Since large differences occur between existing global land cover maps, current ecosystem and land-use science lacks crucial accurate data (e.g. to determine the potential of additional agricultural land available to grow crops in Africa). Volunteers are asked to review hotspot maps of global land cover disagreement and determine, based on what they actually see in Google Earth and their local knowledge, if the land cover maps are correct or incorrect. Their input is recorded in a database, along with uploaded photos, to be used in the future for the creation of a new and improved global land cover map."

TomTom Satnavs To Set Insurance Prices

jeu 09-02-2012

We mentioned this type of possibility a few times in the past, and it's getting more and more real ; Slashdot it discussing a story named TomTom Satnavs To Set Insurance Prices.

Their summary: "TomTom has signed a deal with an insurance firm that will see its satnavs used to monitor drivers. Fair Pay Insurance, part of Motaquote, will use monitoring systems built into the TomTom PRO 3100 to watch for sharp braking and badly managed turns, rewarding 'good' drivers with lower premiums and warning less skilled motorists when they aren't driving as they should. 'We've dispensed with generalization's and said to our customers, if you believe you're a good driver, we'll believe you and we'll even give you the benefit up front,' said Nigel Lombard of Fair Pay Insurance."

SpatiaLite 3.0 Released with Excel Spreadsheets Support

jeu 02-02-2012

I failed to find much information about it, but SpatiaLite, the geospatial version of SQLite, reached version 3.0 about a month ago. Anyone knows where to find release notes? I find also funny that on SpatiaLite homepage, it is clearly stated that spatial is not special! :-) Yes, I'll share a followup to my previous entry on the topic (thanks for your feedback!).

On the SpatiaLite topic, here's a blog entry named Spatialite and Excel on talking terms: "The recent stable version of Spatialite, 3.0, supports linking to and importing Excel spreadsheet tables. Read on to see how it’s done. The developers of spatialite have added a driver for *.xls files (thru the FreeXL library ). You can either link to, or import a single sheet from an Excel file [...]"

French Court Calls Free Google Maps Unfair Competition

jeu 02-02-2012

Slashdot runs a discussion named French Court Calls Free Google Maps Unfair Competition.

Their summary: "A French court has ruled that Google is unfairly subsidizing its free mapping products, making for unfair competition with paid services. This might seem ridiculous, but keep in mind that Google started charging for use of its mapping API once the free version had come to dominate the market."

We of course mentioned last October that Google decided to enforce usage limits for the Google Maps API.

Sensor Networks In San Francisco Finds Parking Spots

jeu 02-02-2012

Slashdot discusses a story named Sensor Networks In San Francisco Finds Parking Spots.

Their summary: "You've heard of smart cars, and now, rolling out in San Francisco, is a smart parking system that promises to eliminate the arduous process of finding a parking spot. SFpark is a network of magnetic sensors that have been installed under 8,200 street parking spaces, along with additional information from parking garages and parking meters. These sensors are all linked together in a mesh network, and ultimately link back to a central command center. Drivers can access this parking data via the SFpark website or smartphone app, and see in real-time where parking spaces are available. At any one time, a third of cars on the road in urban areas are looking for parking spots, consuming more fuel, creating more pollution, and causing more accidents. With SFpark, you can see at a glance where there's a parking spot — but in the future, you'll be able to hit a button and have your smartphone direct you to the nearest parking spot."

It's not the first time we discuss location technology to find parking lots.

Is Geospatial Special?

mar 31-01-2012

I work in a large organization. A colleague challenged me this morning regarding whether geospatial is special or not. Here's part of what I wrote. Your comments are of course welcome! Do you agree? Any other arguments or counter-arguments?

Is Geospatial Special?

Does geospatial deserves special considerations or even a special treatment within an organization?

Geospatial is a set of sciences and technologies that are often applied to specific topics, such as a geographic information system for a municipality, remote sensing for the assessment of the impacts of a flood, location-based services for a smartphone, an interactive web map to plan a trip, a virtual globe to visualize weather events, etc. Other than researchers, nobody does geospatial just for the sake of geospatial, practitioners apply geospatial knowledge and technologies to their own needs and objectives.

I'd argue that geospatial *is* special, and here's why;

  • Geospatial data, which includes at a minimum a geographic projection and datum, is not processed, analysed and disseminated by the same methods and tools as non-geospatial data
  • Geospatial data requires software that specifically supports its particularities. Software that not only must support geographic projections and datum to properly store and load the data, but it also provides the methods and algorithms for the processing and analysis of the geospatial data.
  • Geospatial data processing and analysis differs significantly from non-geospatial data. Only with geospatial data you have to consider snapping, overlapping, proximity, line of sights, position accuracy and precision, reprojections, data types like lines, polygons and voxels, specific file formats like the Shapefile and GeoTIFF, mosaicking, spatial generalization and scale change, spatial indexes in spatial RDBMS, and so on...
  • Geospatial data dissemination also differs significantly from non-geospatial data. Displaying geospatial data uses techniques specific to cartography, data is generally conveyed via maps and similar means, it requires specific data formats and web services to ensure their spatial component is conveyed along with the data, etc.
  • Trained geospatial specialists are in much better position to appropriately apply geospatial knowledge, methods and tools to solve complex challenges related to the storing, processing, analysis and dissemination of geospatial data.

In the past decade, we've seen geospatial going from being the playground of trained experts to being accessible to the general public. The advent of ubiquitous free tools such as web maps (e.g. the Google Maps API) and virtual globes (e.g. Google Earth, which has been downloaded nothing less than over 1 billion times), easy and often free access to satellite imagery, and more recently, smartphones and location-based services, educated and enabled many non-geospatially trained users to acquire and use geospatial data and technologies. This is a Good Thing (tm), but does that mean that geospatial isn't special anymore? No. The reasons for considering geospatial as special stated above are still valid and geospatial is indeed special.

But does the 'geospatial' term have a future as a unifying umbrella, grouping together the domains which deals with geospatial data? Maybe not in the long run. Nowadays, people working in remote sensing, geographic information systems, location-based services and global navigation satellite systems don't necessary overlap that much anymore. Does this mean the term 'geospatial' has become obsolete, diluted into its specific traditional sub-branches? I'd say no. Geospatial is still a term useful as a way to refer to all domains which involve data with spatial references.

Google Earth 6.2 Released: Seamless Globe and Google+ Integration

ven 27-01-2012

Yesterday, Google released Google Earth 6.2

From the announcement: "With Google Earth 6.2, we’re bringing you the most beautiful Google Earth yet, with more seamless imagery and a new search interface. Additionally, we’ve introduced a feature that enables you to share an image from within Google Earth, so you can now simply and easily share your virtual adventures with family and friends on Google+. [...] We’ve also made some updates to the search feature in Google Earth. Aside from streamlining the visual design of the search panel, we’ve enabled the same Autocomplete feature that's available in Google Maps." 

On the welcomed seamless globe: "While this change will appear on all versions of Google Earth, the 6.2 release provides the best viewing experience for this new data." Sri Lanka, before and after:

A quick reminder, Slashgeo has its Google+ page too (but it's inactive at the moment, that doesn't mean it's not worth adding it to your circles ;-).

Related, the GEB shares an entry named Google Earth 6 now required for Street View.

FME 2012 News and Safe Software Major Donation

mar 24-01-2012

I am extremely happy to report that Safe Software, the makers of the popular FME spatial ETL tool, have made a big donation to Slashgeo.org - thank you Safe Software! They're taking the sweet spot of being #1 on our top donors list (on the right-hand column).

Here's what might interest you regarding FME 2012:

  • Contest called "Geography Jones and the Temple of Data", open until Friday which has prizes like an iPad2 and $1500 in travel up for grabs
  • Webinar that will describe what's new and great in FME 2012, offered three times on January 26
  • Details on what's new in FME Desktop and FME Server
  • Blog posts on FME 2012, LiDAR, Google Fusion Tables and more to come later this week

We mentioned FME several times since 2006. In addition to this donation, Safe Software also paid for advertising exclusivity on Slashgeo.org for a few months (the top banner). Slashgeo is managed by a registered non-profit organization. You can learn more about getting exposure on Slashgeo.

Don't worry, we're not filthy rich now ;-) Despite this welcomed donation, our budget is still far in the red because of hosting and maintenance fees accumulated since 2005 (this doesn't count hundreds of hours spent by our team of volunteers). You can peak at our open budget while it's still there. I'll have to remove it in order to respect the Google terms of service (we already got trouble with them in the past).

LightSquared 4G Plans Interfering with GPS Prevented by New U.S. Defense Act?

mar 24-01-2012

Via @azolnai I learned about the 2012 Defense Authorization act that may prevent LightSquared, or anyone else, to interfere in any way with military GPS. Related, last week, Slashdot discussed a story named LightSquared Says GPS Tests Were Rigged.

From the NewScientist article: "A clause buried deep in the 565 pages of the 2012 Defense Authorization act passed in December bars the Federal Communications Commission from approving systems that interfere in any way with military GPS. The bill also tells the FCC to supply Congress with a final copy of the report from its working group, which late last year issued a preliminary report warning that a system proposed by telecoms firm LightSquared of Reston, Virginia would cause serious interference. [...] The concern was that signals near the 4G transmitters would be so strong that that would drown out the faint satnav signals reaching the ground. A series of subsequent tests backed up those claims."

The Slashdot story summary: "Would-be cellular carrier LightSquared claims that the company's LTE network was set up to fail in GPS interference tests. 'Makers of GPS (Global Positioning System) equipment put old and incomplete GPS receivers in the test so the results would show interference, under the cover of non-disclosure agreements that prevented the public and third parties from analyzing the process,' LightSquared executives said on a conference call with reporters Wednesday morning."

While we mentioned frequently the LightSquared debacle, those interested in all the details can read All Points Blog's excellent coverage.

If you're not sick of it already, Slashdot runs another story on GPS monitoring and the law, this time, it's named Supreme Court Rules Warrants Needed for GPS Monitoring.

Their summary: "The Supreme Court has issued its ruling in the case of Washington, D.C. nightclub owner Antoine Jones, saying police must get a search warrant before using GPS technology to track criminal suspects. A federal appeals court in Washington overturned his drug conspiracy conviction because police did not have a warrant when they installed a GPS device on his vehicle and then tracked his movements for a month."
