FAQ: What is the navigation data format?
Answer: There are three levels: parent database format, exchange format and storage format. The format is very important for the realization of navigation function.
Parent database format: It is a format for direct editing and storage of navigation data. It is mainly convenient for editing and saving, such as TAB format.
Exchange format: It is a format that can be converted to various application navigation data. Generally, it is an open format to facilitate conversion applications. (e.g. GDF format)
Storage format: originally refers to the format of data stored in the computer, but in navigation, the storage format generally refers to the navigation application format. (e.g. KIWI format)
FAQ: What is a map and what is a national basic topographic map?
Answer: The traditional concept map is a map that selectively shrinks the natural and social phenomena on the surface of the earth on the plane drawing with the prescribed schema symbols and colors according to certain mathematical rules. Such as ordinary maps, thematic maps, various scale topographic maps, image maps, three-dimensional maps, etc. Modern maps have emerged with new varieties such as micro maps, digital maps, electronic maps and holographic photos.
The national basic topographic map is the national basic scale topographic map, referred to as the national basic map. It is a topographic map that is mapped or compiled according to the unified surveying specification, schema and scale series issued by the state. It is the basic map for national economic construction, national defense construction and military operations, and also the basis for preparing other maps. The scale series of topographic maps in various countries are different. China stipulates that seven kinds of topographic maps with scales of 1:10000, 1:25000, 1:50000, 1:100000, 1:200000 (now 1:250000), 1:500000, and 1:1000000 are national basic scale topographic maps. Its measurement accuracy and mapping quantity and quality is one of the important indicators to measure the development level of surveying and mapping science and technology in a country.
