Embodiment

[0029] The data used in the implementation of this embodiment is the spatial information of 100,000-level communication base stations within China.

[0030] This embodiment uses the combination of Apache Tomcat8+OpenLayers4+Cluster aggregation to realize the visual presentation of spatial data, and the specific implementation steps are as follows:

[0031] Step 1: Obtain the tile basemap. There are many ways to obtain the basemap, such as: online resources, suppliers that comply with the OGC Web Map Service (WMS) specification, such as OSM, MapBox, BingMap, BaiduMap, etc.; manual publishing requires With the help of GIS servers such as ArcGIS Server and GeoServer, if you need custom effects, you need to use uDig, ArcGIS and other software to edit and then use the GIS server to publish; this embodiment uses online resources and adopts the crawler method to obtain Google tile data;

[0032] Step 2: Publish tiles: Organize the acquired Google tile data into the format required by...

Abstract

The invention discloses a method for visualizing massive spatial data WebGIS based on OpenLayers4, The combination of Apache Tomcat 8 + OpenLayers 4 + Cluster (aggregation) is used to realize the visualization of spatial data, The invention adopts the brand-new map presentation technology with the highest reliability, and successfully applies the map presentation technology to the massive spatialdata, so that the spatial sense of the geographic information under the massive data is stronger, the presentation effect is more intuitive, and the user experience sense is better.

Description

technical field [0001] The invention relates to the technical field of geographic information visualization, in particular to a solution method for WebGIS visualization of massive spatial data based on OpenLayers4. Background technique [0002] Today, the Internet has become an indispensable tool in daily life. People can order food, shop online, find route information, and implement location analysis. Geographical information has become popular among the public, and more and more people are beginning to use geographic information services to enjoy the convenience and fun brought by geographic information. With the increasing demand for GIS in various industries, the problem of massive data is becoming more and more prominent. The problem of massive data discussed here is mainly to present a large amount of data in the form of vectors in the browser. Generally, if the number of vectors reaches the level of one thousand or more, IE can't stand it anymore. The zoom-in and pan...
