GEOGRAPHY AS THE BASIS OF GIS
In the rush to create bigger and better technical solutions, many in the GIS industry tend to forget that the discipline known as “geography” is the basis of GIS. GIS provides nothing more than the opportunity to manipulate and analyse geographical phenomena using automated systems. In fact, Michael Goodchild, director of the US National Center for Geographic Information Analysis (NCGIA) quite “recently” suggested (Goodchild 1992) that the acronym GIS should be understood to stand for “geographic information science”. This new definition would place more emphasis on analysis of “geographic information” and less on “system”.

Over the past few years there has been a remarkable increase in interest is GIS. Many of the earliest users were in universities, government departments and environmental agencies. Activity in these traditional core areas is now being supplemented by vigorous growth in several emerging markets, the most important one being business and service planning. For many of these new users, the GIS focus to date has been basic mapping and asset management. Other, more advanced, users are modelling data held in integrated databases. This modelling activity is frequently referred to as spatial analysis.
WHAT IS SPATIAL ANALYSIS?
“Spatial analysis” is one of those terms that are so widely used in so many different contexts that it is difficult to define succinctly. Good child (1988, p; 68) offers a good general definition of spatial analysis as “that set of analytical methods which require access both to the attributes of the objects under study and to their locational information”. Openshaw (1991b, p. 18) suggests that what geographers refer to as “spatial statistics”. Anselin (1989) and Goodchild et. Al (1992) prefer to use the term “spatial data analysis” although there seems to be no substantial difference.

From a marketing perspective, the principal attraction of spatial analysis is still probably a psychological one. Marketeers seem to feel that geography is important in that they know that there are major geographic variations in the demand for products. Maybe they feel that geographers should be able to help them perform better and that there might be methods that geographers know about that could be beneficial to them. Those in the industry who believe this will probably already be displaying more confidence in the value of geography than do many geographers!
Yet at the same time it is evident that there are mutual benefits to both the marketing industry and to geography from closer collaboration. The geographer might gain access to data not in the public domain, new publishing opportunities may arise and there is at least some prospect for technology transfer and commercialization. The marketing industry might gain access to a largely untapped skill base. The question is, however, which methods, which applications, and which new products might be created through such collaborations?

Networks are collections of connected linear objects such as roads, railroads, or rivers that branch from place to place. They come in different sizes, numbers of branchings, and angular configurations.

What if it was easier to predict how a city could have clean air, broader economy, increase safety and reduce traffic? The transportation engineer Josie Kressner assessed the viability of using targeted marketing data for demographic data in travel demand modeling in her dissertation, employing alternative methods for updating the transportation planning process. Continue reading TRANSPORTATION PLANNING IDEA
Move, track, deliver, plan, manage and deploy. Today, getting products and people from point A to point B takes more than planning a route and watching traffic reports. We want it fast, reliable and cost effective. We want smart transportation. Continue reading GIS FOR SMART TRANSPORTATION
Dan Scollon, at TED Talks, shows the first image photographed from Earth in 1972, which changed the human understanding of the Earth. 40 years after that image, we collected lots of information about the Earth and were developed many mapping technologies. Dan explains how maps have changed the way of understanding the world. Images of the United States and China at night can, for example, tell the energy consumption, estimate the population and reveal the distribution of this population. Such evolution made possible to evolve from primary cartography to route instructions on a 3D map to a place geocodificated on a tweet! Social networks are not just for posting happy family photos. They serve, for example, to promote revolutions as the Arab Spring. Mobile data also serve as demographic data for traffic information for example, and this Information can be converted into graphs, maps and even animations to reveal travel patterns.
