1.0.4For surveying instruments and tools, regular metrological verification, timely inspection and correction, and enhanced maintenance must be carried out.
1.05This specification uses the mean error as the standard for measuring accuracy, and the double mean error as the limit error.
1.0.6 The basic accuracy shall comply with the following provisions
1.0.6.1. The mean error of the weakest point of the surface control network (relative to the starting point of each network) shall be stipulated as follows according to the needs of the mapping scale [1) The mapping area with a scale greater than 1:500 (including 1:500) shall not exceed 5cm;

1.0.7.2 The elevation system should adopt the 1985 national elevation datum. The built offshore oil and gas fields can continue to use the original elevation system and gradually improve to a unified elevation datum through joint surveys.
1.0.7.3 The survey of offshore topographic maps should adopt the land elevation system or use the 1985 national elevation datum and the theoretical lowest tide level as the depth datum according to the map usage characteristics. When the theoretical lowest tide level is used as the depth datum, the height of the depth datum should be calculated from the local average sea level, and it should be consistent with the national elevation level. Once the depth datum is determined and used in regular water depth measurement, it shall not be changed. 1.08 The surface control measurement adopts the unified Gaussian conformal projection plane rectangular coordinates. 1:500-1:5000 should choose 1.5° or 3 zones: 1:5000~1:10000 should choose 3" or 6° zones. bzxz.net

base, site topographic map and line engineering survey shall comply with the provisions of the "Petroleum Engineering Drawing Standards" and "Petroleum Surface Engineering Design Document Preparation Regulations". The
legend symbols shall comply with the provisions of the "1:5000, 1:10000 Topographic Map Format", "1:10000 Topographic Map Updater Technical Regulations", "1:500, 1:1000, 1:2000 Topographic Map Format" and "Sea Chart Format". 1.0.10 Reference standards:
