Problems solved by technology
Although this icon drawing method is conducive to directly and simultaneously displaying the corresponding reference marks when the map is opened, however, in the face of different maps (due to the different requirements for the map, even in the same geographical location, different maps are displayed in different ways. and display content may be different), it is necessary to draw corresponding icons on the maps for these different maps, which is extremely cumbersome and inconvenient

The invention relates to an icon processing method and system based on a map, and the method comprises the steps: a map open instruction can be received, and the map open instruction comprises a map icon of a to-be-opened map; current longitude and latitude information of maps displayed on a current GIS map is recorded, and a map icon of the current GIS map is different with the map icon of the to-be-opened map; a GIS map corresponding to the map icon of the to-be-opened map is acquired and loaded; according to the longitude and latitude information of the loaded GIS map, current longitude and latitude information of icons and a window pixel coordinate range of the loaded GIS map, processed window pixel coordinates of the icons are determined; and according to the processed window pixel coordinates of the icons, the icons are displayed on the loaded GIS map. According to the embodiment scheme of the invention, GIS maps with different types or different formats can directly realize simple and convenient processing for icons based on longitude and latitude information of icons, and the processing for the same icons of multi-source maps can be also realized.
Description
technical field [0001] The invention relates to the technical field of drawing processing, in particular to a map-based icon processing method and system. Background technique [0002] With the development of information processing technology, GIS (Geographic Information System, geographic information system) maps have also been widely developed and used. Based on the GIS map, various geographical information can be accurately understood, and various related processing can be performed on this basis, including various operations on the GIS map, such as drawing various icon marks on the GIS map based on requirements to meet different needs. Taking the drawing of icon marks as an example, various marks such as traffic lights and buildings can be drawn on the GIS map. Taking the military field as an example, various icons such as military standard maps can also be drawn on the GIS map to facilitate subsequent various tasks. application. In the current way of drawing icon mar...
