摘要
The present invention utilizes NOAA / AVHRR image data provided by a polar orbit meteorological satellite data receiving and processing system to extract cloud cover pixels that are necessary in the process of extracting land cover type or state information. A method and apparatus for automating the removal using the natural characteristics of a cloud. The present invention is to prepare a cloud search reference data uncontaminated by clouds from the past 15 days of NOAA / AVHRR data stored in the NOAA reception and processing system, prepared earlier for the NOAA / AVHRR data received on the day Searching for the clouded pixels using the reference data and writing the search results to a file, thereby automatically removing the clouded pixels included in the received NOAA / AVHRR data by objective criteria. The invention is for providing the user with the video material.
