Water conservation map data model-based flood risk map drawing method and system thereof

Abstract

The invention provides a water conservation map data model-based flood risk map drawing method and a water conservation map data model-based flood risk map drawing system thereof. The method comprises the steps of establishing a map data model according to the related national standards and industrial standards, and embedding the map data model into a system in a template file mode for allowing a user to guide map data; inspecting the guiding data by a well binding rule; guiding into a risk layer and inspecting; performing interpolation and isoline planar processing after qualified inspection; selecting a layout to automatically generate a map; and further performing annotation editing, graph editing and water conservation project intelligent optimization, and outputting a risk graph. The water conservation map data model-based flood risk map drawing method and the water conservation map data model-based flood risk map drawing system thereof have the beneficial effects of driving the automatic charting on the basis of the water conservation map model, displaying a flood risk graph by a standard scheme, selecting the scheme and edition, which are matched, according to the display plotting scale, improving the automation, standardization and unification of the charting to a great extent, realizing the intelligent optimization of the map symbols, and remedying the defects of the traditional GIS charting technology in the water conservation industry.

Description

technical field [0001] The invention relates to a method and system for drawing a flood risk map based on a water conservancy map data model, and belongs to the technical field of water conservancy GIS mapping. Background technique [0002] The water conservancy industry is an important basic industry related to my country's national economy and people's livelihood, and is the basis for the sustainable development of the national economy. my country has always attached great importance to the development of the water conservancy industry. In order to speed up the improvement of the modernization level of my country's water conservancy, the Ministry of Water Resources put forward the requirement of promoting the modernization of water conservancy with information technology. [0003] With the rapid development of the computer industry, electronic maps are more and more widely used in various industries. Due to the different needs of industries, the contents and methods of th...

Problems solved by technology

For another example, a successful water conservancy engineering drawing basically includes two parts: base map data and water conservancy thematic data. If there are special needs, it may be necessary to superimpose the necessary combination table, that is to say, drawing a water conservancy map needs to be extracted from a large number of data files Existing drawing tools such as AutoCAD cannot preprocess these data files, and more manual processing is required

[0008] Zhang Jing and others mentioned the production of water conservancy thematic maps in the article "Analysis of the Making of Water Conservancy Thematic Maps" (Surveying and Spatial Geographic Information, April 2010), but they only briefly described some basic concepts and water conservancy map making The basic process, and did not explain the specific implementation methods such as the design structure of the water conservancy map making tool
