GIS Fundamentals

GIS Fundamentals

With GIS technology increasingly available to a wider audience on devices from apps on smartphones to satnavs in cars many people routinely use spatial data in a way which used to be the preserve of GIS specialists. However spatial data is stored and analyzed on a computer still tends to be described in academic texts and articles which require specialist knowledge or some training in computer science. Developed to introduce computer science literature to geography students GIS Fundamentals Second Edition provides an accessible examination of the underlying principles for anyone with no formal training in computer science. See What‘s New in the Second Edition: Coverage of the use of spatial data on the Internet Chapters on databases and on searching large databases for spatial queries Improved coverage on route-finding Improved coverage of heuristic approaches to solving real-world spatial problems International standards for spatial data The book begins with a brief but detailed introduction to how computers work and how they are programmed giving anyone with no previous computer science background a foundation to understand the remainder of the book. As with all parts of the book there are also suggestions for further sources of reading. The book then describes the ways in which vector and raster data can be stored and how algorithms are designed to perform fundamental operations such as detecting where lines intersect. From these simple beginnings the book moves into the more complex structures used for handling surfaces and networks and contains a detailed account of what it takes to determine the shortest route between two places on a network. The final sections of the book review problems such as the Travelling Salesman problem which are so complex that it is not known whether an optimum solution exists. Using clear concise language bu

Bosch GIS 1000 C Professional Thermal Camera - BSH601083370

Bosch GIS 1000 C Professional Thermal Camera - BSH601083370

The Bosch GIS 1000 C Professional Thermal Camera is ideal for precise reading and documentation of temperatures and relative humidity. While recording measurements, the device's integrated camera conveniently captures images for instant display with the relevant values. Detailed data is quickly documented and can be shared to remote devices thanks to the Bosch ThermalOn app via Bluetooth connection. The thermo detector delivers a temperature recording, offering professionals five different modes for complex surface and contact temperatures (with integrated K-type functionality) , dew point and thermal bridge calculations, and a user mode for custom values. Along with measuring surface and contact temperatures, the GIS 1000 C Professional's ambient sensor also quickly monitors surrounding conditions for precise measurement of room temperature and relative humidity, enabling an even wider range of applications. A straightforward user interface allows intuitive operation and delivers high-accuracy results on a wide measurement range. Professionals can use the thermo detector in a range of applications, from determining mould risk to checking thermal bridges, as well as for accurate contact measurement of reflective surfaces, liquids, and direct air temperature. The GIS 1000 C Professional is not suitable for medical purposes. Supplied with: 1 x Quick-start Card, 4 x AA 1.5V LR6 Battery, 1 x Micro USB Cable and 1 x Carrying Bag.
