[0022] PDA, English full name Personal Digital Assistant, translated as Personal Digital Assistant. A PDA with an operating system and application development capability can be called a handheld computer. The outstanding feature of the PDA is that it has both the intelligence of a computer and the mobility that a computer does not have. It relies primarily on handwriting and other pointing devices, and relies entirely on touchscreen technology for input. Especially suitable for those places and outdoor use where electricity is strictly prohibit...

Abstract

The invention relates to a method of collecting and maintaining the basic geography information in the electronic map and geography information system application field, which comprises the following steps: equipping with flush bonding map flat on the palmtop; equipping with host system map flat on the computer; proceeding derived operation before field operation collection; deriving the collecting original map from the data base of the computer to the palmtop; drafting various basic map with the palmtop on the spot when the collection is field operation; determining reference point with flush bonding GPS receiver when pinpoint is needed; collecting map object position information directly and saving the collected position information directly with arrow diagram form in the corresponding diagram layer of the basic map; proceeding leading-in operation and achieving dynamic maintenance and maintenance of the basic map information. The method achieves dynamic administration and immediate updating, which provides the convenience and the probability of collecting high strength and distant data.

Description

technical field [0001] The invention belongs to the application category of electronic maps and (GIS) geographic information systems, and relates to a method for collecting and maintaining basic geographic information. Background technique [0002] Electronic map is to use mature network technology, communication technology, GIS (Geographic Information System) technology to realize a new map service method. Electronic maps do not have the texture of paper, but reinterpret the concept of maps in people's minds. [0003] Compared with paper maps and CD-ROM maps, online electronic maps have the characteristics of unlimited information and can be added at will. It is not limited by scale and graphic style, with lower abstraction and better objectification, and can intelligently display the information you need according to your intentions. [0004] Since there is a special person responsible for collecting various data, the online electronic map can be updated at any time: new...
