Embodiment Construction

[0025] like figure 1 , the steps of the present invention include:

[0026] 1) Import the topographic map SHP data collected digitally by GPS / PDA in the field survey, and add the data to the map;

[0027] 2) Based on the data of the hypermap symbol library, configure the symbol library, set the editing symbols and their symbol properties;

[0028] 3), set the XML configuration file, and record the "feature-symbol" configuration relationship;

[0029] 4), storing the configuration relationship of "feature-symbol" in the XML configuration file into a hash list;

[0030] 5) Obtain the data layer of the map, find and call out the "feature-symbol" configuration relationship in the hash list according to the attribute value of the land type attribute representing the land object, call the symbol from the symbol library, and carry out the symbol change;

[0031] 6) Check if there is any feature in the data layer that has not been assigned a symbol, if so, reconfigure the symbol l...

Abstract

The invention discloses a method for quickly mapping by batch symbolization. The method based on a super map symbol library comprises the following steps of: (1) importing topographic map SHP data which are obtained by field measurement, and adding the data to a map; (2) configuring the symbol library; (3) setting an extensive makeup language (XML) configuration file to obtain a ground object-symbol configuration relationship; (4) storing the ground object-symbol configuration relationship into a hash list; (5) obtaining a data layer of the map, and according to ground class attributes of ground objects and the ground object-symbol configuration relationship, calling symbols from the symbol library to perform symbolization; and (6) checking whether the ground object without the symbol exists in the data layer, if so, reconfiguring the symbol library, if the required symbol is absent, adding the symbol into the library and resetting the XML file. The invention discloses the method for mapping by the batch symbolization; and due to the adoption of the method, the graphic drawing and editing speed of topographic maps are increased, the graphic quality is improved, and the batch calling and the quick and accurate drawing of topographic map symbols are realized.

Description

technical field [0001] The invention belongs to the field of basic surveying and mapping, relates to geographic information mapping technology, and is a map symbolization method, specifically a batch symbolization fast mapping method. Background technique [0002] Traditional office map processing requires professional surveyors and mappers to use digital map editing and processing software, and rely on the relationship sketches drawn by the field. After spending a lot of time checking the data, manually add symbols for each topographic and feature element, which is time-consuming It is laborious and affects work efficiency and image quality. In addition, as grass-roots departments such as village and town construction and land management, due to their lack of economic strength and technical constraints, it is difficult to carry out surveying and mapping of topographic maps, resulting in the inability to meet the urgent needs of my country's new rural construction planning m...
