Description

TECHNICAL FIELD

[0001] The present application relates to the field of geological surveying technology, and in particular to a field ecological geological surveying auxiliary device. BACKGROUND

[0002] Ecological geological surveying plays a crucial role in environmental protection and sustainable development. It reveals the structure and function of ecological systems by analyzing the relationship between geology and ecology, and helps us understand the impact of geological factors on biological communities and the feedback of biological communities on geological environments. The role of ecological geological surveying mainly lies in the following aspects: first, assessing the status of ecological systems and identifying the root causes of environmental problems; second, providing scientific basis for resource utilization and ecological restoration; third, maintaining ecological balance and promoting sustainable development. Through ecological geological surveying, we can better develop ecological protection measures and achieve a win-win situation of economic development and environmental protection.

[0003] There are many types of field ecological geological surveying auxiliary devices, such as compasses, a traditional and reliable direction indicating tool suitable for situations without electronic signals or requiring accurate measurement of geological interface occurrence; auxiliary drawing devices such as GPS, drawing boards, pencils, rulers, etc. These devices or equipment can help locate and navigate, assist survey personnel in planning routes, and record geological phenomena, ecological characteristics, etc. The use of latitude and longitude positioning determines the specific location and direction within the survey area, ensuring that the drawn figures conform to the actual geological and ecological conditions.

[0004] In the traditional geological surveying and mapping process, it is sometimes necessary to determine the area where a certain geological phenomenon or ecological feature is located. The staff needs to mark a large number of positioning points on the map or drawing board marked with latitude and longitude, and then draw lines by connecting the positioning points. In the process of marking the positioning points, the latitude and longitude of the positioning points on the map are first determined, and a point is determined by two latitude and longitude lines. When determining the latitude and longitude of the lines, a caliper and a pencil are used to draw the scale line, which may have some deviations, causing the latitude and longitude lines drawn to shift, resulting in some errors in the latitude and longitude of the positioning points, and causing the actual drawn area to deviate from the actual geological and ecological area. Therefore, a field ecological geological surveying auxiliary device is proposed. SUMMARY
