Method for integrally managing geographic information and cartographic data

Abstract

The invention relates to cartography, in particular to a method for integrally managing geographic information and cartographic data used in a digital map and a GIS (geographical information system, the same hereinafter). The problems that the geographic information and the cartographic data are mutually independent and not associated with each other, conversion is difficult and the consistency cannot be easily ensured can be effectively solved. According to the technical scheme, the cartographic data conforming to the map publishing requirements are obtained through mapping treatment of regular symbolization, special mapping effect treatment, lettering configuration, symbolic conflict treatment and the like of the geographic information; and the element-level association between the geographic information and the cartographic data is built in a database through a unique identifier of the element. By the method, integral management can be effectively carried out on the geographic information and the cartographic data; and the geographic information production and management levels are improved.

Description

1. Technical field [0001] The invention relates to map drawing, especially a method for integrated management of geographical information and map drawing data used in digital maps and GIS (Geographic Information System, the same below). 2. Background technology [0002] Geographic information and cartographic data are generally regarded as two separate sets of data. The former focuses on the management, query and analysis of geographic information, which cannot meet the requirements of cartography. The latter focuses on the accuracy and beauty of cartographic expression, and cannot take into account the needs of data analysis. . The main limitation of this mutual separation and non-correlation is: the two sets of data are stored and updated in a completely separate manner, and there are great difficulties in mutual conversion, and it is difficult to ensure the consistency of the two data, resulting in a large amount of data redundancy , which reduces the efficiency of map m...

Problems solved by technology

[0002] Geographic information and cartographic data are generally regarded as two separate sets of data. The former focuses on the management, query and analysis of geographic information, which cannot meet the requirements of cartography. The latter focuses on the accuracy and beauty of cartographic expression, and cannot take into account the needs of data analysis.

The main limitation of this mutual separation and non-correlation is: the two sets of data are stored and updated in a completely separate manner, and there are great difficulties in mutual conversion, and it is difficult to ensure the consistency of the two data, resulting in a large amount of data redundancy , which reduces the efficiency of map making and greatly increases the cost of map making
