The government of the Czech Republic did not allow Google Inc. to implement an expansion of its “Street View” data mapping system by taking additional photos because of privacy concerns.
In a statement posted on its official website, the Office for Personal Data Protection described Google’s program as taking pictures “beyond the extent of the ordinary sight from a street”, and that it “disproportionately invade citizens’ privacy.”
Google Street View provides panoramic photos of many streets in cities around the world. Privacy groups are concerned that their activities which they do not want to be made public will appear in Google.
Internet search giant Google and its data mapping applications have been the subject of scrutiny by government authorities in France, Germany, Italy and Spain because of the same privacy and security issues.
Just last month, the company’s Seoul office was raided by South Korean police in connection with its “Street View” program. (more…)

Street View yazılımı, Google’un topladığı fotoğraflar, küresel konum belirleme sistemi GPS ve coğrafi bilgileri kullanarak sokakların panoramik görüntüsünü sunuyor.
2007 yılında uygulamaya konan Street View sayesinde internet kullanıcılarının istedikleri kentte sokak sokak ‘sanal yürüyüşler’ yapmaları mümkün.
ABD merkezli şirket, şimdi bu hizmeti Almanya’daki 20 kenti kapsayacak şekilde genişletmek istiyor.
Ancak uygulamayı destekleyenler kadar eleştirenler de var.
Google kameraları bir çok ülkede bu kadar tartışma yaratmadı. Ancak BBC Berlin muhabiri Stephen Evans, Almanya’da aşırı tepki çekmesi üzerine şirketin, bu uygulamayı veto seçeneği sunduğunu belirtiyor.
Der Spiegel dergisi, binlerce kişinin tercihini, yaşadıkları yerlerin bu uygulamada bulunmaması yolunda kullandığını yazdı.

Mapping the Segregation of U.S. Cities September 26, 2010

Many people have an anecdotal sense of what areas in a particular city are predominately black, white, or other ethnicity. Eric Fischer has a more precise sense, creating maps that visually represent segregation in urban areas. Using Census Bureau information and the methodology of cartographer Bill Rankin, who produced a racial map of Chicago, Fischer created maps for each of the forty largest cities in the U.S. Here, for example, is the one for Detroit, one of the most obviously segregated urban areas. White areas are pink, Black ones are blue, Hispanic orange, and Asian green.
What This Map Contributes to the Discussion This mapping methodology, writes Cliff Kuang, was “originally …created because [the creator, cartographer Bill Rankin] was frustrated with the way racial boundaries continue to be mapped.” How so? “Usually, ethnic neighborhoods are shown as homogeneous, sharply bounded swathes of color. But obviously, living in a city tells a much different story–and the nature of the boundary areas are at least as important to the identity of any city.”
Don’t Judge Too Harshly Jacob Davies at Obsidian Wings finds the maps interesting, but adds: “I don’t think there are any other countries with much better integration than the US. Race is a really easy in-/out-group marker…”
San Francisco Is Pretty Integrated! remarks Cliff Kuang at Fast Company. “While some parts … are very, very white, large tracts of the outlying bay communities such as Oakland” are much more mixed, “perhaps partly because no one minority totally dominates a single area.”

İstanbul Trafik Denetleme Şube Müdürlüğü’nün trafik kazalarına ilişkin hazırladığı raporda, kentin sık kaza yaşanan noktaları ve alınacak önlemler belirlendi. Rapora göre ölümlü kazalar Mahmutbey, Akşemsettin, Sadabat ve Hasdal viyadüklerinde yoğunlaşıyor
İstanbul Trafik Denetleme Şube Müdürlüğü’nün yaralamalı ve ölümlü trafik kazalarına ilişkin hazırladığı raporda, kentin sıklıkla kaza yaşanan noktaları ve alınacak önlemler belirlendi. Raporda, Mahmutbey gişeleri ile Çamlıca gişeleri arasındaki çevre yollar değerlendirildiğinde, Çakmak Rampası paralı yol ayrımı, Molla Gürani Viyadüğü, Okmeydanı ayrım ve katılımı, Seyrantepe mevkisi, Mahmutbey Viyadüğü ve Akşemsettin Viyadüğü’nde yoğun olarak yaralama ve ölümle sonuçlanan trafik kazalarının meydana geldiği belirtildi.
VİYADÜKTE ÖLÜM ZİLİ ÇALIYOR
Bu mevkilerde gerçekleşen trafik kazalarının viyadüklerde yoğunlaştığı, kaza tespit tutanaklarında bu kazaların önemli bir kısmının sürücü hatalarından ve özellikle kış mevsiminde viyadüklerde aşırı buzlanmadan kaynaklandığı kaydedilen raporda ‘’Yaralamalı trafik kazalarında, hafif yaralamalı olanları Fatih Sultan Mehmet Köprüsü gişe sahası ve köprü üzerinde gerçekleşmekte, ağır yaralanmalarla neticelenen kazalar ise ölümlü trafik kazalarında gözlenmekte ve yoğunlukla viyadüklerde meydana gelmektedir. Özellikle Mahmutbey, Akşemsettin, Sadabat ve Hasdal viyadükleri kazaların yoğunlaştığı viyadükler olup, İstoç mevkisinde de sıklıkla gerçekleşmektedir’’ görüşüne yer verildi. Trafikte riskli olarak gösterilen bölgeler ve çözüm önerileri şöyle:

Project Auckland: Spatial plan critical to new look Auckland September 17, 2010

Unification provides a once in a lifetime opportunity to transform Auckland into a prosperous global city that offers unparalleled quality of life, with a vibrant culture, pure environment, and strong social cohesion – a city that truly deserves the title “world class”.
To deliver that vision, the new Auckland Council, its controlled organisations and its community-focused local boards have collective and mutual responsibilities to deliver unified leadership, clear strategy, people focused organisational capacity, inclusive democratic processes, highly effective administration, strong implementation capability and world class social, cultural and physical infrastructure.
Of these opportunities, infrastructure is perhaps the easiest part to get right. It requires achieving agreement about the kind of city we want to have, how and where it should grow, shaping land use patterns to lead that growth, determining the best way to fund the necessary investment and deploying public and private capital to make it happen.
The development of a unified spatial plan, supported by a prioritised and funded infrastructure plan is the critical first step.
In reality, this should not be too difficult. Auckland has had a growth strategy in place since 1999. Its regional transport strategy has remained substantially unchanged in the last decade.

Forester Yeshi of the royal Manas national park (RMNP) will now use computer software applications, instead of topography sheets, to draw detailed and more accurate maps of the protected areas.
The forester from the range office in Umling was among the 23 foresters that attended a 10-day basic training on geographic information system (GIS) and global positioning system (GPS) at the park’s head office in Gelephu. The training ended yesterday.
The GPS provides reliable location and time information and the GIS can store, manage, analyse and present data linked to any particular location. Both systems are computer application tools used for survey and mapping.
“I’ll download GPS data recorded in the field and create maps with the help of GIS and position it in maps,” he said. “It’ll give me a clear-cut picture of the whole topography of the place I’ve been to.”
Forest officials, who attended the 10–day course that ended yesterday, told Kuensel that until now they had used GPS provided by the government to record data for trekking purposes and marking places. “We’d come back and manually draw maps by hand,” a forester said. “With GIS we’ll be able to provide better information about the park,” Yeshi said.

Hedge fonlar ve bazı Wall Street şirketleri, piyasadaki ekonomik faaliyetleri ölçmek için Soğuk Savaş döneminde sıkça başvurulan uydudan gözetleme yöntemini kullanıyor.
Reel ekonomideki gidişatı ölçmek için çekilen bu fotoğraflar genellikle ABD’de faaliyet gösteren DigitalGlobe ve GeoEye gibi uydu takibi yapabilecek araçlara sahip olan firmalar tarafından sağlanıyor.
Bu firmalar, çektikleri fotoğrafları özel sektör uydu bilgileri analizi yapan şirketlerin yanı sıra ABD istihbarat servisleriyle de paylaşıyor.
Fark yaratmak isteyen İsviçre bankası UBS gibi kurumsal yatırımcılar son dönemde müşteri trafiği ve ekonomik faaliyetlerdeki gidişatı görmek için bu yönteme başvurmaya başladı. Bu tip yatırımcılar fotoğraflardaki park alanlarının doluluğu, limanlardaki canlılık ya da petrol rafinelerindeki doluluk oranı olmak üzere birçok yol gösterecek veriyi karar alma süreçlerinde kullanıyor.
Gov 2.0 Summit Preview: GIS-Powered Government Data September 1, 2010

While government agencies are already making wide use of geographic information systems, the Obama administration’s Open Government Directive provides an opportunity to do even more with GIS, according to market pioneer Jack Dangermond. At the Gov 2.0 Summit in Washington, D.C., next week, Dangermond will outline new initiatives aimed at helping agencies use GIS to make information more transparent and easier to grasp.
Dangermond, president and founder of GIS software provider ESRI, will speak in a session titled “Open Data and the Future of Mapping and Location-Based Services.” Gov 2.0 Summit runs Sept. 7 and 8 at the Grand Hyatt Washington. The event is co-produced by O’Reilly Conferences and UBM TechWeb.
GIS systems use geographic information to generate maps that can be used in a variety of ways. Governments around the world use GIS for a range of tasks, such as managing land use, responding to disasters, and making decisions about where to place landmarks and highways, Dangermond said. As the U.S. government aims to be more transparent through open government initiatives, GIS can play an even more pivotal role, Dangermond said in an interview previewing his Gov 2.0 Summit presentation.
