The increasing popularity of the Internet has led to the development of Web applications, known as Web GIS. A geographic information system (called GIS from now) is a software system that manages geo-referenced information. GIS systems are an automated system used for storing, analysing and manipulating geographical information. Geographical information represents objects and actions where geog...
This paper reviews the use of geographic information systems (GIS) software for spatial data processing in demography. The review begins with an introduction to GIS. Next, it traces the three major types of spatial data problems confronting demographers: the geocoding and geoprocessing of microdata, estimation of detailed population surfaces, and combining data aggregated to incompatible zone s...
Web-based geographic information system (GIS) technology, or web-based GIS, offers many opportunities for public planners and Extension educators who have limited GIS backgrounds or resources. However, investigation of its use in planning has been limited. The study described here examined the use of web-based GIS by public planning agencies. A 2013 web-based survey of 274 public planning agenc...
GIS assist in specific planning and decision-making processes in irrigation through the input, spatial analysis and output of relevant information. The real strength of GIS is its ability to integrate information. This integration power makes the scope of GIS almost infinite. The unique integration capability of GIS allows disparate data sets to be brought together to create a complete picture ...
In physics, objects can be divided into rigid and soft objects according to the object deformation capacity. Similarly, geo-object can also be classified into rigid geo-objects (e.g., building, urban) and soft geo-objects (e.g., mudflow, water, soil erosion). There are three types of approaches for 3D GIS modeling, i.e., surface-based, volume-based, and hybrids in terms of geometry. These appro...
The security model proposed for the Geographic Information Systems (GIS) is a data, which is capable of visualizing technology and has the capability to apprehend, cache, verify, amalgamate, engineer and exhibit data with the help of digitized maps. It has enormous applications in the field of engineering, business management process, communication both in the private and public regions. A GIS ...
To improve the efficiency of existing emergency response and facility management systems, many utility companies choose to implement the ArcFM GIS. Based on my experience designing and implementing an ArcFM GIS for the Potomac Electric Power Company (PEPCO), Washington D.C., this paper provides a road map through implementation of an enterprise-wide GIS using technologies built-on ArcInfo 8 pla...
For analyzing partial discharge ultrasonic wave characteristic on typical defects in SF6 gas insulation switchgear (GIS), a 110 kV GIS was taken as an object to design and simulate the typical partial discharge models in GIS There are point electrode model on bus and cavity of GIS, floating electrode model, air interstice model in insulator, metal particle and iron core electromagnetic shock mo...
GIS systems are frequently coupled with fuzzy logic systems implemented in statistical packages. For large GIS data sets including millions or tens of millions of cells, such an approach is relatively timeconsuming. For very large data sets there is also an input/output bottleneck between the GIS and external software. The aim of this paper is to present low-level implementation of Mamdani’s fu...
درپى هشدارهاى ناشى از بحران انرژى، متخصصین حیطه هاى مرتبط با معمارى نیز باید رویکرد انرژی-کارائی را در تمامی مراحل فرآیند طراحی و ساخت مد نظر قرار دهند. از مهمترین ابزارهاى مؤثر در این زمینه، شبیه سازی رایانه ای مصرف انرژی است. تحقیقات در مورد قابلیت ابزارهای شبیه سازی موجود، غالباً کلى بوده و بندرت پژوهش هایی در زمینه قابلیت های مطلوب در حوزه معماری صورت گرفته است. در نوشتار حاضر، ابتدا شبیه سا...
