AI Technical Summary

Technical Problem

The existing three-dimensional terrain service release technology requires the merge and cropping of all DEM data, resulting in huge processing time and resource consumption, especially when large-scale geographic data coverage.

Method used

According to the three-dimensional terrain service request sent by the client, the required DEM data is determined and added to the corresponding tile grid to generate the target data of the three-dimensional terrain service, avoiding the step of merging first and then cropping.

Benefits of technology

It greatly improves the release efficiency of three-dimensional terrain services, saves data processing time, realizes real-time browsing of massive terrain data, and provides more instant three-dimensional terrain services.

Abstract

The present application provides a method and device for generating a three-dimensional terrain service, the method comprising: receiving a three-dimensional terrain service request sent by a client; determining at least one target tile grid for display on a display interface of the client based on a target terrain area and a target browsing level; obtaining at least one target DEM data for filling the target tile grid from the initial DEM data according to the latitude and longitude range of the target tile grid, and adding each target DEM data to the target tile grid to generate three-dimensional terrain data of the target terrain area; converting the three-dimensional terrain data to obtain target data for generating the three-dimensional terrain service, and sending the target data to the client so that the client displays the three-dimensional terrain service based on the target data. According to the generation method and the production device, the publishing efficiency of the three-dimensional terrain service is improved, and instant three-dimensional terrain services are provided to users.
