Unit is millimeter (on the map)
Mountainous and high mountainous land
The edge joining error of the image data of the digital orthophoto map should not be greater than 2 pixels, and the edge joining accuracy of the band change map can be relaxed to 3 pixels: the vector data should be seamlessly joined.
Image color mode

Image Positioning
Digital orthophoto map images are raster data composed of two-dimensional pixels, arranged in rows from top to bottom in the horizontal direction and in columns from left to right in the vertical direction: the raster coordinate of the first image in the upper left corner is set as (0.0), and the corresponding Gaussian plane coordinate (X-start, Y-start) (see Figure 1) is the starting point. In general, the raster coordinate system is parallel to the plane coordinate system, and the plane coordinate value of the raster should be an integer multiple of the pixel resolution 2

6.1 Content
The content of orthophoto maps shall include images, vector elements, annotations, map outline decoration, etc. Vector elements shall include public single network and internal map lines, and lost land features such as roads, railways, and boundary lines may be added as needed. The annotation should indicate the seat of the government, and other annotations can be selected according to the scale, importance, and information load of the map.

6.2.1 Image
Orthophoto map The images in the entire map should have moderate contrast, uniform color, clear texture, rich layers, no obvious distortion, and the grayscale histogram is generally normally distributed. There should be no obvious grayscale or color changes at the image mosaic, and the image information cannot be interpreted and the accuracy loss due to image defects (such as unclear image texture, noise, image blur, image distortion, offset, cracks, holes, stains, scratches, etc.) should be avoided.
GB/T33182—2016
6.2.2 Quantity elements
The vector elements of the orthophoto map should be semi-transparent in principle of not completely blocking the image base map, or some elements should be uniformly processed according to the principle of overall image beauty. The line type, symbol, and representation method are shown in Appendix B, and the examples are shown in Appendix C. The graphics and annotations of vector feature elements should be complete, the lines should be continuous, the fit should be accurate, and the edges should be well connected. 6.2.3 Overlay principles
When vector elements are overlaid with images, the loss elements should be overlaid on the images in the order of points, lines, and surfaces from top to bottom; after overlaying, the relationship between vector elements and images and between vector elements should be properly handled. The connection between vector elements and images should be natural and reasonable. The overlay order of vector elements can be adjusted according to their importance. The continuity of linear and surface loss elements can be adjusted according to their purpose. The relationship between loss elements shall be handled in accordance with the provisions of GB/T20257.2. 6.2.4 Map outline decoration
