GB/T 33182-2016 in English

National Basic Scale Map 1:5000, 1:10000 Orthophoto Map Standard Interpretation

This standard specifies the composition, technical requirements, content and expression, quality inspection and marking of the national basic scale map 1:5000, 1:10000 orthophoto map, and is applicable to its production, quality control and use. This article will provide a detailed interpretation from multiple dimensions and provide implementation suggestions.

Comparison of standard frameworks

Technical requirements interpretation and application cases

Mathematical basis:Use the 2000 National Geodetic Coordinate System, Gauss-Kruger projection, and divide the zone according to the longitude difference of 3°. Ensure the accuracy and uniformity of the data.

Framing and numbering:Follow the GB/T13989 standard to achieve standardized management and application of maps.

Image processing:The image needs to have moderate contrast, uniform color and clear texture. Use Map Matrix 1.0 for full digital photogrammetry to ensure image quality.

Background of Standardization and Technological Evolution

With the rapid development of surveying and mapping technology and remote sensing image applications, the standards for national basic scale maps are also constantly updated. From traditional paper maps to digital and vector expressions, the application scope of orthophoto maps has expanded to urban planning, land and resources management and other fields.

Implementation Suggestions

Data quality management:Strictly carry out quality inspection and acceptance in accordance with GB/T18316 to ensure accuracy and completeness.

Metadata management:Refer to CH/T1007 to establish a complete metadata structure to improve data traceability and interoperability.

Packaging and distribution:Use CDs or disks as the main storage medium to ensure that the packaging is complete and contains necessary marking information.
