Main Technical Content: 1. Scope: This document specifies the basic requirements for high-resolution remote sensing monitoring of marine raft-based aquaculture areas, data preparation and processing, information extraction from cultivation areas, data review and accuracy evaluation, and the production of monitoring products. This document is applicable to high-resolution remote sensing monitoring of marine algae and shellfish raft-based aquaculture areas. 2. Normative References: The content of the following documents is incorporated into this document through normative references. Among them, the referenced documents with a specified date apply only to the version corresponding to that date; for documents without a specified date, the latest version (including all amendment sheets) applies. - GB/T 15968: Specifications for the Production of Remote Sensing Image Maps - GB/T 18316: Quality Inspection and Acceptance of Digital Mapping Results - DB37/T 4518: Technical Specifications for Remote Sensing Monitoring of River and Lake Shorelines 3. Terms and Definitions: The following terms and definitions apply to this document. 3.1 Interpretation Key: Image features on remote sensing images that specifically reflect and distinguish land features or phenomena, divided into direct interpretation keys and indirect interpretation keys. Note: Direct interpretation keys include hue or color, shading, size, shape, texture, and pattern; indirect interpretation keys include location and combination. 3.2 Raft-Based Aquaculture Area Monitoring: Monitoring the distribution, area, and temporal and spatial changes of marine algae and shellfish raft-based aquaculture areas. 3.3 Radiometric Calibration: Establishing a quantitative relationship between the digitally quantified brightness output value (DN) and the radiation brightness value in the corresponding field of view, to eliminate or correct radiation errors caused by image radiation distortion. 3.4 Atmospheric
