Detailed Description
The following description of the embodiments of the present application will be made clearly and fully with reference to the accompanying drawings, in which it is evident that the embodiments described are only some, but not all, of the embodiments of the present application. All other embodiments, which can be made by one of ordinary skill in the art without undue burden from the present disclosure, are within the scope of the present disclosure.

Any embodiment or design described herein as "exemplary" or "for example" should not be construed as preferred or advantageous over other embodiments or designs. Rather, the use of words such as "exemplary" or "such as" is intended to present related concepts in a concrete fashion.
It should be noted that, in the embodiment of the present application, "english: of", "corresponding" and "corresponding" may sometimes be used in combination, and it should be noted that the meaning to be expressed is consistent when the distinction is not emphasized.
In order to clearly describe the technical solutions of the embodiments of the present application, in the embodiments of the present application, the terms "first", "second", and the like are used to distinguish the same item or similar items having substantially the same function and effect, and those skilled in the art will understand that the terms "first", "second", and the like are not limited in number and execution order.
Before explaining the embodiments of the present application in detail, some technical terms and related techniques related to the embodiments of the present application are described.
Geographic information systems (Geographic Information System or Geo-Information system, GIS) are sometimes referred to as "geoscience information systems". It is a particular very important spatial information system. The system is a technical system for collecting, storing, managing, operating, analyzing, displaying and describing the related geographic distribution data in the whole or partial earth surface (including atmosphere) space under the support of a computer hard and software system.
Geographic information system products refer to desktop GIS, server GIS, development GIS, mobile GIS, etc. products of the major components of GIS, such as the major applications of desktop GIS for creating, editing, designing and using geographic information, server-side GIS data management software, including data collection, organization, management, analysis, visualization and distribution services, development GIS toolkits for providing programmable to developers, mobile GIS application products for deploying GIS technology on a range of mobile devices. The products form a telescopic and extensible complete geographic information platform, and the spatial information, the spatial analysis function and the spatial information service are extended into the organization of the whole enterprise, so that personnel of each level and department share the spatial information service.
arcGIS provides a scalable, comprehensive GIS platform for the user. ArcObjects contain many programmable components, ranging from fine-grained objects (e.g., single geometric objects) to coarse-grained objects (e.g., map objects that interact with existing ArcMap documents) that are extremely broad-valued, integrating comprehensive GIS functionality for developers.
The open geospatial information alliance (Open Geospatial Consortium, OGC), an international standard organization for non-profit, sets a series of standards for data and services according to which GIS vendors develop interoperation with guaranteed spatial data. OGC formulates an organization specification WKT of spatial data, expressing geometric types in text form
JavaScript (abbreviated as "JS") is a lightweight, interpreted or just-in-time compiled programming language with functional prioritization. Although it is a scripting language that is famous for developing Web pages, it is also used in many non-browser environments, javaScript is based on a prototype-programmed, multi-paradigm dynamic scripting language, and supports object-oriented, command-style, declarative, functional programming paradigms.
OpenLayers is a JavaScript class library package specially provided for Web GIS client development and is used for realizing map data access published in a standard format. Since the openlayers2.2 version, openLayers has integrated the prototype/js components used into itself, and continuously perfects object-oriented development based on prototype/js, rico uses little place, but fillets DIV in the OpenLayers.
With the growing maturity of geographic information systems, more and more users are beginning to install and use electronic map applications on personal computers or mobile terminals.
However, the conventional electronic map can only generate a visual map according to the base map to be displayed and the map component to be displayed, and when the visual map is displayed, only a single position point is displayed on the map, but the associated position point corresponding to each position point cannot be displayed, so that the user experience is reduced.
ArcGIS, although it may implement superposition of multi-dimensional layers, is used to segment data along defined variables and dimensions, thereby creating raster layers from multi-dimensional raster data sets or multi-dimensional raster layers. This tool creates a multi-dimensional grid layer from a multi-dimensional grid or mosaic dataset by extracting a subset of variables. For example, the mosaic dataset contains 30 years of month precipitation data, whereas the user only wants to extract 1 month per year data to see the change in month precipitation. The supported multi-dimensional raster data set includes a Cloud Raster Format (CRF), a multi-dimensional mosaic data set, or a multi-dimensional raster layer generated from netCDF, GRIB, or HDF files. The tool will generate a temporary layer that will not be permanently preserved unless it is saved to disk. Obviously, the ArcGIS service framework is heavier and comprises too many functions of fixed formulas, which is not beneficial to the expansion and development of service functions.
In view of this, the embodiment of the application provides an electronic map display method, compared with the method for generating a multidimensional layer by ArcGIS, the method is more flexible and changeable, processing logic can perform secondary development according to a result desired by a user, and associated position points corresponding to each position point are displayed on an electronic map, so that user experience is improved.

The electronic map display device determines chromaticity information of the associated position points and renders the associated position points according to the chromaticity information so as to display the associated position points in the electronic map. Compared with the prior art, when the map is displayed, the position of each position point is displayed on the map only singly, but the associated position point corresponding to each position point cannot be displayed.
