ESRI Launches ArcGIS.com and ArcGIS Explorer Online

New Resources Give Users the Ability to Share GIS Content and Build Communities

ESRI announces the launch of ArcGIS.com, a Web site for finding and sharing geographic information system (GIS) content, organizing geographic information into groups, and building communities. A new browser-based version of ArcGIS Explorer, ArcGIS Explorer Online, also launches with the site and provides direct access to ArcGIS.com content.

Through ArcGIS.com, visitors can access a number of free, ready-to-use basemaps for their projects and applications, including community maps that have been built with data from organizations around the world. To create maps and mashups quickly and easily, a JavaScript Web Mapping application is available. ESRI gives users its high-quality basemaps as a starting point, and they can then search ArcGIS online content or other GIS servers and the Web to find additional layers for mashups. These mashups can be shared and consumed by others, including those with the ArcGIS for iPhone mapping application. Additionally, ArcGIS.com allows people to share their maps and apps with everyone or specific groups that they join to collaborate on specific projects. Users can create their own groups and invite others to join and share their content.

A new and exciting ArcGIS application with which to open and view GIS content is ArcGIS Explorer Online. ArcGIS online content can be accessed directly from within ArcGIS Explorer Online to create maps that can then be shared and consumed by a broad community of users, including the iPhone community.

Visitors to ArcGIS.com can access publicly available content without having to sign in. To take advantage of the extended capabilities of ArcGIS.com, such as uploading and sharing items, users can log in using their existing ESRI Global Account information. Users who don’t have an ESRI Global Account will be directed to a page where they can create one.

Spatial Analysis of Municipal Water Supply in Abeokuta Metropolis, South Western Nigeria

REAL CORP 2010 Proceedings/Tagungsband, Vienna, 18-20 May 2010

G. C. Ufoegbune, J. A. Oyedepo, Awomeso, A. O. Eruola

“The study examined the spatial dimension of Public Water Supply in Abeokuta Metropolis with the aim of providing effective planning, development and operation of water supply and distribution networks which is one of the most essential components of urban infrastructure. A number of factors ranging from population expansion to inadequate existing facilities are thought to be responsible for the frequent shortage in water supply to the metropolis. The study delineated the areas within the metropolis that are un-served or underserved by the Water Cooperation. A framework for taking management decisions such as an extension of the supply network and location of new facilities was given. Large sale facility maps that will serve as source of information for vital application for the Ogun State Water Cooperation in carrying out its daily functions were produced. Such maps in digital forms are extremely vital and are useful to integrate collateral data i.e. available within the corporation.”

Impact Assessment of Future Climate Change for the Blue Nile Basin, Using a RCM Nested in a GCM

Nile Basin Water Engineering Scientific Magazine, Vol.2, 2009

Eman S.A. Soliman, M. A. Aty Sayed, and Marc Jeuland

“This paper establishes a basis for evaluation of climate changes impacts within the Blue Nile River subbasin, using the RegCM3 Regional Climate Model to simulate interactions between the land surface and climatic processes. The RegCM3 model nested with the ECHAM5 General Circulation Model (Max Planck institute) were applied and the obtained results are presented.. The results were then fed as inputs to the Nile Forecast System NFS) (a distributed rainfall runoff model of the Nile Basin) and the interaction between the climatic and hydrological processes on the land surface was fully coupled. Rainfall patterns and evaporation rates were generated using RegCM3, and the resulting runoff and Blue Nile streamflow patterns were simulated using the NFS. The results, obtained from the RegCM3 climate model, were compared to the observational datasets for precipitation and temperature from the Climate Research Unit (UK) and the NASA Goddard Space Flight Center GPCP (USA) for the period 1985-2000. The validity of the stream-flow predictions from the NFS is assessed using historical gauge records. Finally, the modeling results of the A1B emissions scenario of the IPCC for the years 2034-2055 are presented. The results indicated that the future changes in rainfall might vary over different areas of the Upper Blue Nile catchment in Ethiopia. This suggested that there might be a good reason for developing climate models with finer spatial resolution than the commonly used GCMs.”

Adapting to the Impacts of Climate Change

…a new study from the National Research Council…

“Reducing vulnerabilities to impacts of climate change that the nation cannot, or does not, avoid is a highly desirable strategy to manage and minimize the risks, says the third book, Adapting to the Impacts of Climate Change. Some impacts–such as rising sea levels, disappearing sea ice, and the frequency and intensity of some extreme weather events like heavy precipitation and heat waves–are already being observed across the country.

“The book notes that policymakers need to anticipate a range of possible climate conditions and that uncertainty about the exact timing and magnitude of impacts is not a reason to wait to act. In fact, it says boosting U.S. adaptive capacity now can be viewed as “an insurance policy against an uncertain future,” while inaction could increase risks, especially if the rate of climate change is particularly large.”
