This article as a PDF. Figure 1: Web GIS concept diagram This article provides GIS managers and analysts with an understanding of the fundamental concepts of Portal for ArcGIS and its capabilities. Traditionally, GIS has been a technology used by analysts to perform spatial analysis and generate custom map products that meet the specific needs of their organizations. Web GIS is a pattern for delivering GIS capabilities. At the center of the web GIS pattern in the ArcGIS platform is the generic concept of a portal that represents a gateway for accessing all spatial products in an organization. Figure 2: Web GIS deployment models The ArcGIS platform offers two deployment models for web GIS. Although there are two separate web GIS deployment models, hybrid deployments that combine parts of the cloud-based model with parts of the on-premises model are not only possible but very popular.

Commission on Map Design | Website of the newly established ICA Commission on Map Design GIS Education Community Geography summer camp? I will be offering an exciting 5-week online course beginning 25 May 2016 entitled Teaching Geography for the 21st Century. You can register here. Geography Summer Camp: Online Course 2016. Geography is considered one of the world’s oldest disciplines, pioneered by Eratosthenes in 250 BC, and has a rich tradition of scholarship and innovation. Furthermore, why should geography be taught in the 21st Century? I will teach this course through eNet Learning, whose mission is to provide high-quality professional development, content, and resources that support educators and student learning. This course is designed to build geographic concepts, perspectives, and skills for those teaching geography and those teaching other disciplines who seek to use the geographic framework. See you online in our “Geography Summer Camp”!
Ushahidi The modifiable areal unit problem (MAUP) The Modifiable Areal Unit Problem The modifiable areal unit problem (MAUP) is an important phenomenon associated with the use of data aggregated to geographical areas. It affects the aggregation of events, individuals or households and therefore applies to many variables of interest in the social sciences, including, for example, unemployment and ethnicity rates. In these cases, the geographical boundaries are 'imposed' in the sense that they do not relate in any meaningful sense to the variables of interest. Typically, data are aggregated from source observations to areas such as census wards or output areas which have no special meaning in terms of the underlying geographical distributions such as unemployment or ethnic composition. MAUP refers to the fact that the observed aggregated values will vary according to how we draw our area boundaries.
