Recognition for GIS Innovation

Dr Richard Mather, lecturer at the Department of New Media and Technologies at Buckinghamshire New University (UK), has been awarded The Institution of Analysts and Programmers (IAP) Prize for Software Engineering. Dr Mather has worked at Bucks since 1996 and his IAP award was recognition for his MSc dissertation, completed at the University of Oxford. The dissertation, "A Workflow Application and XML Datastructure for Processing Geo-referenced Images", is of particular interest to the GIS, remote-sensing and land-management communities. It allows the automation of image processing, in contrast to existing techniques, which are often ad hoc and circumstance-specific."Bearing that in mind,... (read more)

Web-based GIS

Integrating Geo-data from Multiple Sources
The next phase in GIS development on the internet should restore user freedom and give a fully comprehensive overview of geo-objects originating anywhere and containing all relevant information. It should be fully integrated and freely applicable. The author envisages data from multiple resources integrated for process support by combining (geo)graphical and other (administrative) data using Web-technology. Six years ago our firm began, like others of its kind, with application developments based on the first available map servers. User-interfaces, specific applications and administrator modules were built on an ad hoc basis, with demand-driven Internet Map Servers (IMS). Great effort had to... (read more)

Decision-making and GIS

The most common use of GIS is as a historian’s tool, to describe a situation over time. In this, its value reflects the currency, quality and accessibility of the input data. These factors have generally improved greatly in recent years so, in that sense, it is unsurprising that GIS has grown so substantially, according to David Rhind. (By David Rhind, ret. Vice-Chancellor, The City University, UK) But many see the greater role of GIS as a decision-making tool, especially where this involves bringing together data from many sources. How do we know if this really is successful? There are two... (read more)

GIS and Disasters

The last eighteen months have seen a series of disasters leading to substantial loss of life. Examples include Hurricane Katrina, the Pakistan earthquake, and bombings in cities such as London and Bali. All disasters happen somewhere. Where they happen influences the impact and our ability to respond. Scientists seeking to identify natural hazards and what can be done to mitigate them must also deal with the geography of risk. Geography is therefore central to both planning for and countering disasters. GI and GIS are increasingly at the forefront of government efforts to carry out their first duty in protecting their...

GIS for Hydrological Modelling

Gagetown Hydrologic Model
Estimating rainfall discharge is difficult in large catchment areas with varying topography. This leads to widespread inadequacy in culvert design, with resultant damage to these and other drainage infrastructure during storms, when water runoff is high. The authors developed three ArcGIS-based hydrological models which accurately estimate rainfall discharge for storms that occur anywhere between once every two weeks up to once a century, enabling improvements in culvert infrastructure design. The test results prove the potential for GIS to aid in the creation of highly accurate hydrological models. Although there have been hydrological models in existence for decades, we designed our...

GIS in Archaeology

The Human/Environment Interface of Maya Settlements
Throughout history the physical and cultural environment has influenced location and distribution of settlements. One important question in archaeological research is what are the causal relationships between environmental factors on the one side and location and distribution of settlements on the other? The authors demonstrate GIS to be a powerful analytical tool in finding answers to this question as it relates to Maya settlement patterns in Central America. Clues to the relationships between environmental factors and location and distribution of settlements are preserved in many existing maps. Combining these maps with remote sensing data and non-spatial information from a variety... (read more)

Next Generation GIS Portal

The US Department of the Interior has selected ESRI (CA, USA) to develop full implementation of the Geospatial One-Stop Operational Portal (GOS 2), providing new ways of sharing geospatial information to improve decision-making processes. Since its launch in July 2003 the prototype has provided a central site for posting and discovering metadata about agency resources. The experience ESRI gained through administering GOS 1 has directly led to improvements in usability and functionality. The GOS site compiles more than 75,000 metadata records. GOS 2 uses the proven Google Search Appliance for a new method of integrated spatial and subject searching. Metadata... (read more)

Thinking About GIS

Esri Press has released the fourth edition of Thinking About GIS: Geographic Information System Planning for Managers, the seminal book on planning and implementing a geographic information system (GIS). Roger Tomlinson, widely known as "the father of GIS," has updated this edition to include the latest trends in geospatial technology.   Drawing from decades of Tomlinson's consulting experience and worldwide GIS seminars, this book bridges the communication gap between senior managers who oversee information technology systems and technical specialists who design and implement the systems. It provides common ground for both groups so that each clearly understands the methodology needed... (read more)

Medical Mobile GIS Tracking

Every healthcare provider, in order to make decisions, needs specific information from external sources made available to them more than fifty times a day. The challenge is obvious: better methods have to be found to get ‘the right information to the right person at the right time.’ Developments in integrating (geospatial) information technologies, including GPS, remote sensors, wireless networks, smart cameras and internet-linked communication systems, make it possible to achieve this aim. In the wake of these developments there is growing interest on both the medical and geomatics side in decision support using advanced (geospatial) technologies. The development of wireless...
