TABLE OF CONTENTS GPS applications are systems or devices that use positioning information to provide specific services or benefits to the user. Some key GPS applications include mapping, location monitoring, agriculture control, navigation, navigation warfare (NAVWAR), surveying and structural deformation monitoring.
Because the GPS system has higher accuracy and much faster position updating than other location systems, it can be used to enhance or enable new applications. For example, continuously measuring position, this allows GPS receivers to determine their velocity.
Mapping is the process of gathering position information so that the locations and possibly the attributes of the items (e.g. roads or towers) can be presented in a form that is interpreted by a user.
Utility maps are graphic displays of the types of utilities that located in a specific geographic area. Utility maps may combine several map layers. Utility maps may be composed of location and terrain details of rivers, trees, land contours, roads and other maps can be combined with utility facilities to produce utility maps.
Geographical information system is a data processing system that is capable of gathering, analyzing and providing geographic information. GIS systems are used to create maps or display the results of queries for the location of objects or systems.
GPS can be used with other position ranging systems to gather data for a geographical information system. GPS signals may provide the primary location information and the secondary position information is gathered from other systems such as sonar or laser...
