Development of a Symbol System for Disaster Management

Spatial information plays a key role in disaster management. Upon occurrence of an emergency situation, crisis management actors need specialised maps to give them a clear idea of the emergency, localisation, distribution and characteristics. Effective representation of spatial information can be achieved by means of graphical symbols. Silvia Marinova describes how a symbol system should be associative and quickly perceived by map users even without the use of a legend, especially in an emergency. A number of agencies and organisations related to disaster protection develop databases, geo-portals and cartographic products for crisis management and their own standards for symbols. In...

Deciding Between FOSSGIS and Proprietary Software in the Enterprise

FOSSGIS (Free and Open Source Geographic Information Systems) is an umbrella term for Open Source GIS projects. In the following article, Tim Sutton (QGIS project chair and director at Kartoza Pty Ltd.), explains how and why FOSSGIS makes its way into an enterprise environment. Is FOSSGIS ready for the enterprise environment or is proprietary software better? Let's start with the hypothesis that, as a GIS professional, you wish to ‘tool up’ with the optimal set of software and hardware needed to carry out your duties. Having good instrumentation to measure what is the ‘best’ software is thus critical. In my... (read more)

Creative Traps in Maps

Maps undoubtedly play an important role in society. From use in daily life to professional applications, maps help us navigate, plan activities and gain insight into our surrounding environment. Although we know that all maps have a certain accuracy, we rarely question the existence of streets and places we find on a map. Throughout time, however, various cartographers have used our good faith in maps to protect their work from being stolen. Their creative ways to trap copyright violators has led to a variety of map ‘mistakes’, some of which have survived for years before being discovered. This article presents... (read more)

Visibility Maps of Turin

Including Atmospheric Conditions in Viewshed Analysis of DSMs
High-rise buildings affect the skyline of a city and thus the human perception of urban spaces. From which points can a building, or parts of the building, be seen? The answer requires viewshed analysis of raster or vector 3D city models. Visibility is not just a geometric exercise in which lines of sight are calculated using standard GIS tools. Visibility and perception of space are also determined by atmospheric conditions, contrast between foregrounds and backgrounds including the sky, visual acuity and psychological aspects. Here, the authors present a simple but accurate method for generating visibility maps based on the above... (read more)

Mapping the Past

Anyone who has tried to accurately match old Ordnance Survey maps with the current Landranger series will soon realize that it is not an easy task. Brian Quinn explains the painstaking process that Cassini Publishing has been through in creating its unique range of historical maps. Amelia Earhart’s observation that “it’s easier to start something than to finish it” is certainly true, as any writer stuck at the bottom of page one will testify. But when, and how, do things finish? Often there is no definite conclusion but rather a steady progression that leads past or round the original goal... (read more)

Experimenting with Low-cost UAVs

The use of Unmanned Aerial Vehicles (UAVs) as serious remote sensing platforms is a growing trend. They are already used in fields such as archaeology, construction, disaster relief, and the oil and gas industry. Sandy Avery and Bruce Gittins argue their ability to be deployed and produce results quickly, requiring only a small team to operate, enables their use in hardtoreach places. Though the financial and technical cost of using UAVs is constantly dropping, there are still high entrance barriers to their use. Many purposebuilt survey drones cost in excess of tens of thousands of pounds and require a significant... (read more)

Recharged, we Face New Challenges

Did you attend GeoCom 2015 in November? If you didn’t you missed a lively and truly informative event, which must surely have re-charged every delegate’s verve for all things GI related. In these tough times, when company budgets for conferencing are often non-existent and time away from desks is in even shorter supply, the AGI managed to organise two (and a half if we include the Foresight 2020 report on the evening of 23 November) very attractive days, especially around plenaries and debates. We’ve reported on Day One in this issue (pages 14-17); in February we’ll cover Day Two. In... (read more)
