The Atlas of Sustainable Development of the Yangtze River Economic Belt is an open new type of atlas. It uses a block-type structure to reflect four levels from point-to-line, face-to-face, from the whole view of the river basin to the microscopic view of the central city.
1) From the macroscopic to the microcosm, to present a complete map of the Yangtze River with a series of maps of resources, economy and population in the whole basin;
2) The economic radiation circle along the Yangtze River is an economic zone with a traction radius. It is not only a regional complex but also a Yangtze River economic belt that affects each other and restricts each other.
3) Taking the cities along the center of the river as scattered points, highlighting the city's development and investment environment.
4) Based on pictures and texts, the construction of key projects in the Three Gorges Project will be introduced as a supplement to the Yangtze River Economic Belt.
At the time of design, the electronic version of the Atlas fully considered the arrangement of the atlas and the characteristics of the content. On the basis of the original plate-type structure, it fully utilized the multimedia display means and explained the words and sounds, the structure of the plate structure, and the entire Yangtze River Economic Belt. Watersheds, districts, and urban remote sensing image presentations are given to give a rough introduction and demonstration. Make readers have a clearer and more intuitive understanding of the framework and theme content of the entire atlas.
At the time of reading, the electronic version of the atlas is mainly composed of four large groups of maps. In the form of maps, illustrations, and query items, the tree-like branches and nesting structures are used to hierarchically display the contents. The structure is illustrated as follows:

2.1 Map data processing
As a visual digital map product, electronic maps are based on the basic features of reading on a computer screen. The screen displays the speed, the zoom speed is directly related to the amount of map data, and its storage medium CD-ROM space is limited. All of these factors make electronic map data and published digital map data for purposes different in terms of data volume and representation. Therefore, for the characteristics of electronic maps, digital maps must undergo data processing and drawing redesign, and follow the following principles:
1) Under the premise of ensuring that the drawing surface is not distorted, the data size should be compressed as much as possible, and the vectorization collection density should be thinned out;
2) On the basis of maintaining a clear and complete legend system, remove as much as possible special effects such as gradients, transparency, glows, shadows, and solids that were designed to increase the appearance of the artwork in the original image, simplifying the lines and symbols, and creating beautiful surfaces. Complex digital content with clear content and small amount of data;
3) For the computer screen features and color characteristics, adjust the color design of the Atlas surface, so that it is color-coordinated and soft, clear, and suitable for screen reading without losing the original appearance;
4) According to the size of the computer screen, adjust the layout of the map, re-design drawings;
5) According to the multi-scale scale opening window enlargement function, related maps are used for point, line and area element classification editing;
6) Under the premise of ensuring a clear display, compress the image size and resolution to reduce the storage space, the screen display image resolution is usually 72-90dpi to meet the requirements.

A pet harness is equipment consisting of straps of webbing that loop nearly around-that fasten together using side release buckles-the torso of an animal.
These harnesses generally are made to have both a strap on the chest in front of the forelimbs, and a strap around the torso behind the forelimbs, with straps in between connecting these two. Having a D-ring suitable for (pet tags and) a leash to clip to, they are most often used to restrain an animal, but dogs also particularly wear them to assist a person with a disability or haul people and items. There is also the lifting harness for dogs with disabilities, covered in this article.
Some come in different sizes, although many are size-adjustable with tri-glide slides to loosen or shorten the straps` length. The straps may come in a range of different colors, and some have reflective coating.
