Basic surveying and mapping

Concept

Basic surveying and mapping refers to the general term for surveying and mapping implemented to provide basic geographic information for national economic and social development, as well as for various departments and professional surveying and mapping in the country. Basic surveying and mapping must be carried out in accordance with national unified planning and unified technical standards throughout the country or in specific regions.

Typical case

Surveying and Mapping Project for Old Residential Areas in Gaoyang County

It involves 75 buildings in 22 old residential areas in Gaoyang County, with a total area of 213745 square meters. The total construction area of the main building is 322805.15 square meters, and the total construction area of the tool room is 31759.1 square meters. The main job responsibilities are as follows:

1. Architecture (1) Verify the location and road width of the building on the overall plan, measure and photograph the original green space and its scope, and reflect it on the overall plan (2) The size and height of the community wall should be reflected in the overall plan to indicate its location (3) Measure and reflect the size and location of entrances and exits in the community on the overall plan (4) Buildings not reflected on the overall plan need to be added to the overall plan
2. Rainwater and sewage (1) The location of municipal rainwater and sewage access points is reflected in the overall plan
3. Electrical (1) The current weak current main line routing in the community, including the location of municipal access, is reflected in the overall plan (2) Number of households in each row of small rooms
4. Heating (1) Heating external overhead pipeline routing for family buildings of the Environmental Protection Bureau, postal and telecommunications communities, Jinxin communities, transportation bureau family buildings, vocational education centers, and county-level communities

Exploration and Definition Project for Optimizing Ecological Red Line Area in Chabei District

The ecological protection red line refers to the areas within the ecological space that have special and important ecological functions and must be strictly protected. It is the bottom line and lifeline for ensuring and maintaining national ecological security. It usually includes ecologically important areas with important water source conservation, biodiversity maintenance, soil and water conservation, wind and sand prevention, coastal ecological stability, as well as ecologically sensitive and fragile areas such as soil erosion, land desertification, rocky desertification, and salinization. Boundary surveying and mapping refer to the act of conducting on-site investigations and mapping of the ecological protection red line boundaries that have been delineated, approving the coordinates of turning points, surveying precise boundaries, and establishing unified and standardized boundary markers and signs. Boundary markers refer to boundary markers set up along the ecological protection red line boundary in a certain manner, with information such as the location and nature of the ecological protection red line attached. A signboard refers to a signboard set up in a prominent location for the purpose of warning and publicity, containing basic information such as the name, area, scope, function, and supervision of the ecological protection red line.

Ecological Red Line Boundary Survey and Calibration Project in Saibei Management Area, etc

1. Data collection and analysis: Conduct data and information collection, summary, and analysis work, complete unified mathematical foundation and data format conversion work.
2. Production of working base map: Overlay the ecological protection red line delineation data with unified mathematical foundation and data format (approved by the State Council in February 2018) and collected high-resolution image data, extract suspicious boundaries or patches from the ecological protection red line data through a combination of computer interpretation and manual interpretation in the office, complete pre annotation of boundary points, pre annotation of boundary markers, pre selection of sign positions, and other work, and produce paper and electronic working base maps.
3. On site boundary survey: Based on the working base map and relevant data extracted from the office, various methods such as field measurement, drone image acquisition and supplementary survey, and office graphics are used to conduct on-site survey and accurate landing of the ecological protection red line boundary in Saibei District. The coordinates of different patch ecological protection red line boundaries, pre marked boundary points, pre marked boundary markers, and pre selected signs are clearly defined in the field. Detailed information about the ecological protection red line on-site boundary survey is recorded, and on-site boundary survey photos are taken. The boundary marker registration form and other forms are completed.
4. Setting of boundary markers and identification signs: According to the production standards of ecological protection red line boundary markers and identification signs, identification signs shall be set up at key control points and prominent positions, and relevant information shall be registered and stored in the database.
5. Theme map production: Produce thematic maps related to the demarcation and marking of ecological protection red lines in Saibei District.
6. Data library construction: After passing the quality inspection, the basic data, maps, tables, and text results of the completed ecological protection red line demarcation and calibration work in the northern part of the country will be integrated to establish a database for ecological protection red line demarcation and calibration in the northern part of the country.
7. Results organization, acceptance, and submission: Check, organize, and submit the completed ecological protection red line demarcation data results, document results, and map results in accordance with requirements; And cooperate to complete expert argumentation, inspection, acceptance, county-level, city level, provincial-level internal audits, field inspections, on-site spot checks, etc.
