electronic map

The contents of the pictures are painted or printed on these carriers. The electronic map is stored on the hard disk, floppy disk, CD-ROM or magnetic tape of the computer, and the map content is represented by numbers, which need to be displayed, read, retrieved and analyzed by special computer software. The amount of information that can be expressed on electronic maps is far greater than that on ordinary maps. For example, roads on ordinary maps are marked with lines, and different symbols such as the shape, width and color of lines indicate the grade of roads and other information. On the electronic map, the location is represented by a series of X and Y coordinates, and the information such as the grade of the highway is represented by the attributes of drawing lines, such as'1'for the expressway and' 2' for the national highway. There are many attributes of lines drawn on electronic maps, such as highway grade, name, pavement material, name of starting and ending points, road width, length, traffic volume and other information can be used as attributes of a road. [1] Edit the function of this paragraph. Electronic map is a system of map making and application. It is a map controlled by computer and generated based on digital mapping technology.

Screen map is a visual real map. Visualization of computer screen is the basic feature of electronic map. Electronic map has the following six characteristics: 1. Can be quickly accessed and displayed. 2. Animation can be realized. 3. Map elements can be displayed in layers. 4. Use virtual reality technology to make the map three-dimensional and dynamic, so that users have the feeling of being there. Electronic map can be transmitted to other places through data transmission technology. 6. It can automatically measure the length, angle and area. It shows that electronic map can easily combine the elements of ordinary map in any form to form a new map. Yes, you can.

Electronic maps can be drawn and output at any scale and in any range. It is very easy to modify and shorten the drawing time. It can be easily combined with other information sources (such as satellite images and aerial photos) to generate new maps. New data can be derived from the information recorded in digital maps, such as contour lines on maps to represent landforms, but it is difficult for non-professionals to understand. Using the contour lines and elevation points of the electronic map, we can generate a digital elevation model, display the surface undulation in digital form, and display the landform intuitively and stereoscopically. This is an ordinary topographic map, which can not achieve the performance effect. The State Bureau of Surveying and Mapping owns1:40,000, 1: 1 10,000 and1:250,000 electronic maps nationwide, and will produce1:50,000 electronic maps in the future, which is an important part of the national basic geographic information system and a carrier for professional information management and analysis in other departments. A large number of large-scale electronic maps, such as 1 ∶ 5000, 1 ∶ 2000, 1 ∶ 1000, have been produced by surveying and mapping and urban planning departments in various provinces and cities, which can be used in urban planning and construction, transportation, tourism, car navigation and many other departments. These digital maps have changed the daily work of various departments from a large number of maps to the work in front of the computer, which is scientific, accurate and intuitive, and greatly improves the efficiency. There are many kinds of electronic maps, such as topographic map, raster topographic map, remote sensing image map, elevation model map, various thematic maps and so on. What's the use of editing this electronic map? First, it is used to find various places and locations. Second, find some tourist routes through the map. For example, how to take a bus, how to drive, what route to choose and so on. Third, learn other information. In addition to geographical location, you can also know telephone numbers, contacts, products and services provided by a company and other information on the map. Fourth, publish information on the map. For enterprises, electronic maps are also a platform for advertising. Editing the characteristics of this paragraph (1) Electronic maps use computer screens and large projection screens as the media, while traditional maps generally use paper as the information carrier. (2) The production, management, reading and use of electronic maps can be integrated, and unsatisfactory places can be easily modified in real time. The production, management and use of traditional paper maps are separated. (3) The details of the map content displayed by the electronic map can be adjusted at any time, while the content of the traditional paper map is fixed. (4) Electronic maps can combine graphics, images, sounds and words, but paper maps can't. (5) The use of electronic maps depends on special equipment, while the use of paper maps does not. (6) Due to the limitation of computer screen size and screen resolution, the display effect of the whole map is affected, which is mainly displayed in blocks and layers. However, the traditional paper map is published and printed in a large format, and the overall impression of the map is profound, and the relationship between geographical elements is clear and clear. Sub-map is a system of map making and application, a map generated by computer control, a screen map based on digital mapping technology, and a visual real map.
