Abstract

The invention provides a discrete site graded display method based on a GIS (geographic information system). The method includes the steps of S1, acquiring the range of a current map according to input longitude and latitude point arrays and a loaded map grade; S2, cutting a region in the map range into grids according to the map grade, and calculating a longitude interval and a latitude interval according to a longitude step length, a latitude step length and the longitude and latitude data of the map range; S3, building the two-dimensional array of the map range, which is cut into the grids, according to the map range, the longitude interval and the latitude interval; S4, setting current grouping to be N groups, and performing traverse grouping of different grades on the input longitude and latitude point arrays according to the longitude step length, the latitude step length, the grouping and the two-dimensional array; S5, displaying the grouped longitude and latitude point arrays in grouped and graded manner according to corresponding current grades.

Description

Technical field [0001] The invention relates to the field of page display of a geographic information system, in particular to a method and device for hierarchical display of discrete sites based on GIS. Background technique [0002] Displaying data points on the Geographic Information System (GIS) page is generally to superimpose all the points on the current page area. If the number of points is too large, it will affect the page loading efficiency, and it is not easy to distinguish the overall points in observation distributed. Therefore, a large number of points are displayed in a GIS map area, and the display points on one screen are too dense, it is difficult to identify the points, and the display effect is not good. [0003] It should be noted that the above introduction to the technical background is only set forth to facilitate a clear and complete description of the technical solutions of the present invention and to facilitate the understanding of those skilled in the ...
