Problems solved by technology

[0002] With the continuous development of science and technology and emerging information technology, land and space planning issues are becoming more and more complex. Some traditional planning that relies on the subjective judgment of planners and ignores quantitative applications is not conducive to improving the scientific nature of planning and limiting the improvement of planning efficiency.

Embodiment 1

[0045] Such as figure 1 As shown, the present embodiment provides a method for constructing a city information database, including:

[0046] S100: Obtain basic topographic maps and pipeline maps; collect place name data and address data through network capture; obtain planning data through the government affairs system; collect actual topographic data, actual pipeline data, and actual place name data;

[0047] S101: Update basic terrain data and pipeline data respectively according to the acquired basic topographic map and the pipeline map;

[0048] S102: Perform data format conversion on the acquired planning data;

[0049] S201: Compare whether the basic terrain data is consistent with the actual terrain data, and whether the pipeline data is consistent with the actual pipeline data;

[0050] S202: Compare whether the place name data is consistent with the actual place name data;

[0051] S301: If the place name data is consistent with the actual place name data, data fus...

Embodiment 2

[0087] Such as figure 2 As shown, this embodiment provides a method for building a city information database. On the basis of Embodiment 1, after obtaining planning data through the government affairs system, it also includes:

[0088] S701: Capture keywords of the planning data, and determine initial attributes of the planning data through the keywords;

[0089] S702: Classify the planning data according to the initial attributes when importing into the database.

[0090] It can be understood that step S701 should be executed before planning class data is imported into the database.

[0091] In this embodiment, preferably, step S701 is executed after data format conversion of planning data and before quality inspection. Specifically, after the planning data is converted into a data format, step S701 is performed: capturing keywords of the planning data, and determining initial attributes of the planning data through the keywords.

[0092] After the quality inspection of t...

Embodiment 3

[0106] This embodiment provides a method for displaying a map, constructing a blank base map, selecting data from the city information database constructed by using the method for constructing a city information database described in Embodiment 1 or Embodiment 2, and displaying the data according to the selected data. on the blank base map.

[0107] A map display method is used to construct a map system, and a map system includes a blank base map, a data call unit and a display unit, and the data call unit is used to select from the city information database of embodiment 1 or embodiment 2 according to user commands The city information database constructed by the construction method selects the calling data, and the display unit is used to display the data called by the data calling unit on the blank base map.

[0108] Urban planning managers can use the data in the city information database to plan and manage the city through the one-picture display system constructed by the...

Abstract

The invention relates to the field of city information management, in particular to a city information database construction method and a one-map display method. The city information database construction method comprises the step of constructing a city information database based on an obtained basic topographic map, a pipeline map, place name data and address data captured by a network, and planning data obtained from a government affair system. Therefore, the data of the city information database is real and reliable, and a city planning manager can conveniently call the data in the city information database to carry out city planning management. The one-map display method comprises the following steps: constructing a blank base map, selecting data from the city information database constructed by the city information database construction method, and displaying the data on the blank base map according to the selected data.

Description

technical field [0001] The present invention relates to the field of city information management, more specifically, to a method for building a city information database and a method for displaying a map. Background technique [0002] With the continuous development of science and technology and emerging information technology, land and space planning issues are becoming more and more complex. Some traditional planning that relies on the subjective judgment of planners and ignores quantitative applications is not conducive to improving the scientific nature of planning and limiting the improvement of planning efficiency. In the context of the new era, traditional planning is bound to undergo its own transformation, so as to achieve precise planning, shrewd management and fine service. [0003] There is an urgent need to establish a unified data resource system, build a planning and comprehensive urban information database, and conduct centralized maintenance and management o...
