A kind of situation map dynamic plotting systemTechnical field
The present invention relates to a kind of plotting systems, and in particular to it is anti-to be mainly used for flood control for a kind of situation map dynamic plotting systemThe dynamic of flood information is marked and drawed.
Background technique
Situation map is using map as base map, using various labels, icon, text, annotation, by the target, action side of taking actionCase, action deployment, resource distribution, personnel form into columns, take action implementation procedure and corresponding job facilities, facilities, weather environment,All information flags relevant to action such as topography and geomorphology react the Dynamic Graph of global situation for obtained one on base map.
However there are a large amount of plotted data in the information that dynamic is marked and drawed is shown, these information are drawn by icon or linesIt makes, partial information is closer to because of its coordinate so there are icon overlay phenomenons during plotting, so no matter markingIt will all make troubles to user during drawing or during showing, and individually judge the display of a certain information or hide to needWant a large amount of type judgement that can realize that this virtually brings a large amount of burden to front end rendering, and the system of resulting even in is run quicklyIt bursts.If publication date is on 2 26th, 2014, in the Chinese patent of Publication No. CN103605463A, disclose a kind of based on GISThe drawing method of the quick situation plotting system of platform and touch panel device, the plotted data Direct Mark in the invention is in GISOn map, more mixed and disorderly in display, user is more inconvenient when using.
