3.1.1 Determination of aerial photography contract
Based on the needs of mapping, the aerial photography fee request shall be put forward. After approval, the main user unit shall jointly discuss the relevant equipment items, formulate a trial flight plan, and sign a trial flight contract. 3.1.2 The main technical contents of the aerial photography contract include: the aerial areas and aerial photography equipment (the aerial photography area should be indicated with a map with a length and material number; the compilation format and requirements of the aerial map should be in accordance with the provisions of G/TG:7619-B; the quality of the map should be compared with the measurement method; the type of aerial photography, technical parameters and required distance of the equipment and related parameters; the name and quantity of the photographic results; the season and period for performing the aerial mission: B/T6962-2005); and relevant technical requirements.
3.2 Aerial photography design
3.2. Selection of design maps
Topographic maps of good quality and regularity should be used as maps for aerial photography design. In order to ensure the accuracy of aerial navigation services, the design maps must be of a relatively precise scale and should generally be used in accordance with the specifications in Table 1 based on the aerial photography scale in the manual. Table design drawing scale

if the area has a full layer of soldiers in the village, the design can be used for 3.2.2 selection of aerial photography scale
the scale should be based on the characteristics of the map to be measured, the uniform conditions of the area to be photographed, under the premise of accurate mapping, it is conducive to shortening the measurement and reducing the cost, and improving the comprehensive benefit of the measurement. The scale of the aerial photography should be selected within the range specified in the table ≥2. :0n

In the case of holding the ball, after negotiation between the user and the aerial photography station, the aerial scale of the river channel and the receiving light table 2 standard, 3.2.3 Division of aerial short zones
The division of aerial photography zones should follow one principle: the zone boundary should be consistent with the survey book map,
) When the temperature scale is less than 1!70C, the difference in terrain within the zone is not consistent with the sky, so the average height of the zone can be used as the benchmark: when the scale is equal to or equal to 1:0, the terrain height difference of the area is greater than six-tenths of the aerial height: (a
) under the condition that the terrain height meets the requirements, the compensation for the zone is forgotten) 3.2.4. Calculate the height of the reference plane of the sub-area photography. The height of the reference plane of the sub-area photography is the average height of the high points in the sub-area: the sum of the average height of the low points ()
3.2.5 The direction of the flight and the method of setting the flight direction
Usually, the flight line should be straight from east to west. Under normal conditions, the terrain can be different from the special map. The flight line should be along the north or south line, along the river, the sea, the wide fertile land, etc., which is suitable for the special media of the industry. The aerial survey map can be placed with large scale. The installation of aerial laser film can simplify the survey operation.5 times>certification, the actual air route is still the core of the barrel ten war number setting: when / = 6-month route should be Swiss center two neighboring medical public real map version technology.
According to the professional surveying and mapping fee, the special reason you line length exciting setting front line, d) control the conventional number of route setting, the route sound parallel to the map rate, the ten-photographing area should generally be in the outer edge of the map or the southern contour line

) Small areas and sea areas should change the route to avoid the main point of falling into the water, ensure that all islands are covered, and form a correct image of the narrow body. The control panel load line (also known as the framework route) 3.2.E Aerial photography factors, calculation of flight time, consumption of flight materials, etc. are stipulated in the regulations of the United States. 3.2.7 Selection of photography time and aerial photography time will determine the best choice for this area. Favorable weather conditions include: good lighting, water ingress, sand in the middle, etc.; ensure that the ship's camera can truly show the details of the pool surface; select the time for aerial photography, and ensure sufficient flash illumination to avoid excessive photography. Generally, the night light is determined according to the solar altitude and shadow multiples of the shooting area. Table 3 shows the terrain lighting system, solar altitude angle and shade factor. ||Mountain moving city

Root non-user requirements, there is no ground sign in the passenger area, the production plan should pay attention to the degree. The ground signs should be completed before the aircraft enters the shaking area. The sign's design should be designed to ensure the safety of the area and the volume, deformation, etc. The color of the sign should be selected according to the light of the objects in the photography area to ensure the quality of the sign. It has good feedback with the latter. In order to enhance the reading efficiency of the mark image and improve the quality of the mark, the laid mark should be as low as possible or as high as possible.
