Abstract

The invention relates to a retrieval method and device for mass transportation remote sensing data. The retrieval method comprises the following steps: acquiring transportation remote sensing data of an earth satellite observation system, wherein the transportation remote sensing data comprises remote sensing image data, the remote sensing image data comprises vector images and raster images, the vector images are in one-to-one correspondence with the raster images; acquiring the retrieval request of a user, wherein the retrieval request carries the search conditions of the user; inquiring the raster data first according to the retrieval request of the user; acquiring a first raster image matched with the retrieval request; acquiring a corresponding first vector image according to the first grid image; determining the first raster image and the first vector image as the business data matched with the request conditions, so that only requiring to search raster data according to the retrieval request, but not searching and matching all the images in the raster data and the vector data in sequence. Therefore, the data retrieval efficiency is improved and the user's requirement for quickly acquiring business data can be met.

Description

technical field [0001] The invention relates to the field of communication technology, in particular to a method and device for retrieving massive traffic remote sensing data. Background technique [0002] At present, after the satellite observation system acquires traffic remote sensing data such as remote sensing image data and geographic vector data, it generally stores the traffic remote sensing data in the data center. When the user wants to obtain business data such as roads, waterways, and navigation, the data center searches and matches all the images in the traffic remote sensing data one by one according to the retrieval conditions related to roads, waterways, and navigation provided by the user, and obtains and retrieves them. Business data that matches the condition. [0003] With the development of the earth satellite observation system, the observation area of ​​the earth satellite observation system is getting larger and larger, the observation frequency is a...
