Abstract
The invention relates to a geographic information data integration method based on drafting data and GIS data. The geographic information data integration method includes the following steps that (1), a GPS, a total station and a balance level are used for control survey and detail survey, and position information and corresponding attribute information of ground objects and landforms in an area are collected; (2), the topographic map drafting data meeting the requirements of a data dictionary are obtained; (3), symbolic parameter information is loaded into corresponding symbols through different informationization functions and recorded into corresponding characteristic elements to form the GIS data with drafting symbol information, and namely geographic information data integration based on the drafting data and the GIS data is completed. According to the method, after office work and a field are integrated to be drafted, the drafting data are changed to be GIS data with the drafting symbol information through a graphic informationization technology, the GIS data with the drafting symbol information are namely integrated geographic information data and therefore information management and application are achieved.
Description
Technical field
The invention belongs to the geographic information data field, especially a kind of geographic information data integration method based on cartographic data and GIS data.
Background technology
Seriously going through at present digital mapping changes to the informationization mapping, have a large amount of primary scale cartographic datas and constantly updating maintenance, GIS demand data of all kinds constantly increases, and the data production model of the situation main flow coexisted in the face of two kinds of demand datas has three kinds:
The first adopts the indoor and field integration numeral to become chart-pattern, and the existing cartographic data of updating maintenance, while needing the GIS data, be converted to by switching software.
This is the production model of Fundamental Geographic Information System production with the employing of the unit of maintenance of most domestic.
The advantage of this pattern is: continued to use the work pattern since digital mapping, met traditional cartographic data demand; Shortcoming is: the cartographic data of maintenance is not easy to build storehouse, and the database of foundation is not easy to management; Few atural object data quality problem can affect the full-automatic realization that cartographic data turns the GIS data; The GIS loss of data generated all symbolic information.
Industry compilation in the second field data acquisition, integrating digital mapping, updating maintenance GIS data.This is that a kind of digital mapping surveys and draws for adapting to informationization a kind of work pattern risen latter stage.
The advantage of this pattern is: directly safeguard the GIS data, can realize preferably the GIS data management, Quick is for the GIS market demand, and the GIS data are owing to having certain symbolic information editor, storage capacity, so can meet the graphic requirement of the GB of most of atural object; Shortcoming is: due to what safeguard, be the GIS data, object of an atural object, limited edit capability, when the complex relationship that complicated atural object or a plurality of atural object cause, can not meet the graphic requirement of GB, limited the user demand of traditional cartographic data.
The third adopts the indoor and field integration numeral to become chart-pattern, the existing cartographic data of updating maintenance, and the GIS data that upgrade in time, safeguard two sets of data.
The advantage of this pattern is: can meet traditional cartographic data and GIS market demand demand; Shortcoming is: safeguard that two sets of data pressure are very large, the production cycle is long.
Summary of the invention
The object of the invention is to overcome the deficiencies in the prior art, a kind of geographic information data integration method based on cartographic data and GIS data is provided, the method design science is reasonable, shorten the production cycle, realize that cartographic data and GIS are data integrated, data volume is little, solves the deficiency that cartographic data is built storehouse, and the GIS data are built storehouse wouldn't provide the technological fix that meets the graphic cartographic data of GB.
The present invention solves its technical matters and is achieved through the following technical solutions:
A kind of geographic information data integration method based on cartographic data and GIS data, its step is as follows:
, use GPS, total powerstation, spirit-leveling instrument to carry out control survey, measure the smashed parts, the positional information of atural object, landforms and corresponding attribute information in pickup area;
, by interior industry Become the picture software by the atural object of field data acquisition, the plotting on computers of landforms positional information, the corresponding attribute information of typing, be atural object configuration line style, symbol, word annotation, be met the topomap cartographic data of data dictionary requirement;
(3), distinguish characteristic element and the symbol element of topomap cartographic data, symbol element is classified and recorded and met parameter information, the key element code that utilizes data dictionary to define is corresponding symbol element one by one, form different marks according to the entity type of symbol element, the excessively different information-based function by the symbolic parameter information exchange, be loaded into respectively in corresponding mark, and be recorded on the characteristic of correspondence key element GIS data that form with drawing(s) symbol information, completed the integration of the geographic information data based on cartographic data and GIS data.
And described data dictionary is Fundamental Geographic Information System factor data dictionary first: 1:5001:10001:2000 Fundamental Geographic Information System factor data dictionary, GB/T20258.1-2007.
And, the point, line, surface of the classification that described characteristic element is accurately expression atural object, geographic position, shape.
And described symbol element comprises point symbol, planar filling symbol, line symbol and word annotation.
And described symbolic parameter information is point symbol parameter information, line symbol parameter information, planar filling symbol parameter information, word annotation parameter information.
And, position, angle information that described point symbol parameter information is point symbol.
And, the line style that described line symbol parameter information is line symbol, closed information.
And, the filling pattern ratio that described planar filling symbol parameter information is planar filling symbol, filling symbol pattern name information.
And described word annotation is position, font, size, angle information.
And, described point symbol mark, planar filling symbol mark, line symbol mark, the word annotation mark of being labeled as.
Advantage of the present invention and beneficial effect are:
For the current state of the art and demand data, the geographic information data integration method based on cartographic data and GIS data is proposed.The method is after indoor and field integration becomes figure, by the graphical information technology, cartographic data is become to the GIS data with drawing(s) symbol information, the geographic information data after integrating, to realize GIS data management and application, existing cartographic data graphical information is changed into to information data or direct production information data, then building database, realize the information data management, solve the deficiency that cartographic data is built storehouse, farthest continue to use existing work pattern, cartographic data and GIS are data integrated; At automatic Symbolic or world-famous puzzle instantly, solve existing GIS data and built storehouse and can not export the technical barrier that meets the graphic cartographic data of GB and realized safeguarding a sets of data, met cartographic data and GIS market demand demand simultaneously.
The accompanying drawing explanation
Fig. 1 is the data plot of the GIS with drawing(s) symbol information after the present invention integrates.
Reference numeral is respectively the GIS data of 1-with drawing(s) symbol information; The 2-symbol element; 3-word annotation; The 4-symbol element; 5-word annotation.
Embodiment
