Description

Method for Construction of Spatial Information Data using Mobile Communication Terminals {Method for Construction System of Spatial Data by Mobile}

The present invention relates to a system and method for constructing spatial information data using a mobile communication terminal. More specifically, the present invention relates to a system and method capable of modifying and updating spatial information data using a digital digital map using a geographic information system, a mobile communication terminal such as a PDA (Personal Digtal Assistant), a mobile phone, a cellular phone, and the like. .

In the case of existing spatial information data, it consists of relevant document data such as property information of objects such as facilities acquired through the graphic management and geographic survey of spatial objects, road ledger, building ledger, and facility manager led by each local government. Becomes Construction of geospatial data has been actively conducted by each municipality since 1995. By constructing drawings and maps of water and sewage, gas, communal districts, electricity, telephones, and road facilities that need to be managed by each municipality as spatial information data, more smooth and standardized work could be performed. It is largely divided into field work and internal work, and field work is divided into field survey and local geographic survey.

For acquiring the spatial information data, the numerical map of the site to be acquired is printed out, surveyed using a precision instrument such as a total station, and recorded on the printed paper map. Recorded paper maps are delivered to internal workers, who then construct site drawings using the CAD program. When the site drawing is completed, it is printed again as a paper map, and the site geographic survey is conducted for each facility at the site, and the attribute information of the facilities acquired through the site geographic survey is constructed as spatial information data by an internal worker.

However, the most costly and time-consuming process of each local government's business is the construction of spatial information data, and the field surveying and acquisition of attribute information of facilities is the most important among the construction of spatial information data. As the process of acquiring the location information and the attribute information of the facility for the existing spatial information data is divided into several stages, the problem of intactness of the data is highlighted, and there is a problem of distrust of the reliability of the data.

Created to solve the problems as described above, an object of the present invention is to unify the work process through the various stages in the construction stage of the current spatial information data directly in the field using a mobile communication terminal, Significantly reduce the omission, misunderstanding, and self-error of on-site data, and provide a system and method of constructing spatial information data using mobile communication terminal to improve time saving and economic efficiency for input work when constructing spatial information data.
