A Traceable Completion Method for Geographical Elevation Data

Abstract

The invention discloses a traceable geographic elevation data complementing method, comprising the following steps: 1. Establishing a plane geographic grid map based on the data accuracy and data range, and performing rasterization and framing management on the original data; 2. According to the plane Geographic raster map, data preprocessing, and data uniqueness and completion from top to bottom; 3. Establish data traceability information and build a data access system with all elements. The invention effectively realizes the complementing method of geographic elevation data, and effectively solves the problems of lack of geographic data, inconsistency of data content and insufficient utilization of data value.

Description

technical field [0001] The invention relates to a traceable geographic elevation data complementing method. Background technique [0002] In the current various geographic information systems and simulation platforms, in order to achieve vivid and real effects, it is necessary to have a complete and effective elevation data as a support. At the same time, the use of elevation data gradually requires large capacity, high timeliness, high concurrency, low delay, low memory usage, and continuous data. How to manage and use these geographic elevation data stably, efficiently, and continuously has become a key technology for the measurement system. The traditional layered control method is increasingly unable to meet the demand, especially the simple geometric mean method is likely to cause data distortion. , thus affecting the usability of the data. Contents of the invention [0003] Purpose of the invention: Aiming at the problems existing in the prior art, the present inve...
