Description
We often deal with maps in engineering projects, so how does the client software load maps? One is to load an online map. The advantage of this loading method is that programming is more convenient when there is a network; the disadvantage is that the need to have a network is not conducive to the display and programming of the map. Relatively another loading method is offline map, this loading method basically has no disadvantages, but it only needs to make offline maps before programming.
