Abstract

The invention discloses a memory, and a GIS-based spatial element data presentation method, system and device. The method comprises the steps of converting a coordinate system of geographic information elements of a target area into a unified coordinate system in a GIS platform; determining a plurality of analysis dimensions conforming to a preset rule in the spatial element data as specific dimensions, and allocating a corresponding color hue to each specific dimension; when the GIS platform-based geographic model of the target area is generated, meshing the spatial element data, and generating a numerical value of each analysis dimension of the spatial element data in each grid in the geographic model; determining a color of an area corresponding to each grid in the geographic model, wherein the color determination comprises the following steps: determining a specific dimension of which the numerical value is in a preset range as a coloring dimension; performing color fusion according to the color hue corresponding to each coloring dimension to generate a presentation hue of the grid. According to the GIS platform-based application system, representation elements and use scenes of the GIS platform-based application system constructed according to the geographic model can be effectively expanded.

Description

technical field [0001] The invention relates to the field of geographic information applications, in particular to a memory, a GIS-based spatial element data presentation method, system and device. Background technique [0002] With the continuous development of technology, Geographic Information System (GIS) has been widely used in different fields. Among them, the visualized city management system based on the geographical model of two-dimensional GIS or three-dimensional GIS can visualize and present various key data of the core system of urban operation, so as to control emergency command, urban management, public safety, environmental protection, intelligence, etc. Provide management decision support in areas such as transportation and infrastructure, and then realize smart city management and operation. [0003] Through the visual urban management system, various statistical data (such as population data and economic data, etc.) can be presented in a graphical way to ...
