“Man has mostly preferred to live in communes and settle in particular areas to survive. Together with the growth of population and immigration, these settlement areas have developed into cities in time. Depending on the rapid growth in science and technology, the economical, cultural and social structures of the cities and so their physical appearances change continuously. Within this rapid and non-ecological structural change and growth, the necessity of open green areas is usually ignored. In fact, open green areas have significant positive effects on man’s psychological renewal, as well as social and cultural development. From this point of view, open green areas are one of the most important spaces in the urban environment that should be considered during the Strategic Environmental Assessment (SEA) process of urban planning. In this study, Geographic Information Systems (GIS) and Remote Sensing (RS) techniques were used for determining suitable lands for open green areas within SEA process in Eskisehir city centre. In addition, the importance of GIS and RS technologies for handling multi-data sets in EIA and SEA studies are also discussed. As a result, environmental and ecological planning studies are performed by analyzing and overlaying hundreds of different data sources. Therefore; the RS and GIS based methodology described in this manuscript is very useful for environmental and ecological planning studies compared with traditional assessment methodology.”
This application is designed to provide simple access to the National Ice Center ice analysis archive. The daily ice edge is constructed by NIC ice analysts using various imagery products with resolutions ranging from 100m to 12.6km. These imagery sources include but are not limited to RADARSAT, ENVISAT, DMSP OLS, AVHRR, and QUIKSCAT.
Since December 2010, floods have been hitting Australia, particularly in Queensland. A new map application is now available to provide updated information. It shows the scope of flood response, including evacuation centers and accessible roads near Brisbane, Australia. The application was created and is maintained by Esri Australia.

“Previous research has indicated that various deprivation indicators have a positive impact on crime rates at the community level. In this article, we investigate the impact of deprivation indicators on crime in Belgian municipalities (n = 589) for the period 2001–06. A spatial regression analysis demonstrates that unemployment figures have a strong and significant impact on crime rates, and this effect is stronger than the effect of income levels. Income inequality has a significant positive impact on property crime rates but a negative impact on violent crime. Crime is heavily concentrated in the urban centres of Belgium, but we also observe some important regional variations. Demographic structure was not related to crime levels, while spatial analysis shows there is a spill-over effect to neighbouring communities for property crime, but not for violent crime. We close with some theoretical and policy considerations on the relation between unemployment and crime.”

“There are several common organizing principles for online communities, notably people, places, and topics. Notable examples include: Facebook and Twitter organize around people, Foursquare organizes around places, and PatientsLikeMe and CNet organize around topics. Of course, these are only a few examples. Moreover, few communities organize solely around any one principle. Most topic-oriented sites support social interaction. Social services like Twitter can – with proper filtering and interfaces – be useful sources for topical information. And some sites combine a local geographic and topic orientation. This is the space my work is situated in and extends.”
