It is to be understood that the specific embodiments described herein are merely illustrative of the invention and are not limiting of the invention. It should be further noted that, for the convenience of description, only some of the structures related to the present invention are shown in the drawings, not all of the structures.
Fig. 1 is a block diagram of a map visualization management apparatus in an embodiment, and referring to fig. 1, the embodiment proposes a map visualization management apparatus, including:
the data template editing module 1 is used for receiving visual data configuration information, and the visual data configuration information is used for determining visual information to be displayed.
For example, the visual management device provided in this embodiment may be applied to an application scenario of site selection and line selection of a power grid project, the visual management device may be configured in a GIS device as a system component, and the visual management device may generate visual data based on a selected map, so that a person may conveniently select a site and line according to actual terrain, features, and the like.
For example, in this embodiment, the visualized data configuration information may include a terrain, a landform, a name of a land feature, a geographic coordinate, and the like, and visualized text information to be displayed on the map may be selected through the visualized data configuration information, for example, if the visualized data configuration information is selected as the terrain, the name of the land feature, and the geographic coordinate, and a landmark building a exists in the map, the terrain around the building a, the name of the building a, and the geographic coordinate of the building a may be displayed in text in the vicinity of the building a.
And the map data extraction module 2 is used for acquiring the visual data configuration information and acquiring the attribute information matched with the visual data configuration information in the selected map.
For example, in this embodiment, the attribute information is geographic information, such as a terrain, a landform, a feature name, and a geographic coordinate, bound to a map in the GIS system, and if the selected visual data configuration information is selected as the terrain, the feature name, and the geographic coordinate, the map data extraction module selects the terrain, the feature name, and the geographic coordinate from the geographic information, and ignores other geographic information, such as the landform.
And the data display planning module 3 is used for determining the area to which the building in the map belongs and determining a plurality of display clusters according to the area and the attribute information, wherein the display clusters comprise highlighted building areas and attribute information matched with the building.
For example, in this embodiment, the data presentation planning module may be configured to identify the outlines of buildings or particular areas (e.g., rivers, roads) in the selected map, and the data presentation planning module may determine the area to which the buildings belong based on the outlines of the buildings.
After the area to which the building belongs is determined, the data display planning module can determine the center point of the area according to the area and the shape of the area to which the building belongs, and record the center points corresponding to all building areas in the map. The data presentation planning module may divide different buildings in the map into different clusters according to the location coordinates of the center point. Illustratively, when generating the cluster, the steps include:
For example, first, using the central point a of the most west and the most north as a reference, another central point B having a set distance from the central point a in the west-east direction is found out by calculation, and then, using the central point B as a reference, another central point C having a set distance from the central point B is found out by calculation, and the above-mentioned process is repeated until the last central point satisfying the above-mentioned condition in the direction is calculated. And then, repeating the calculation process by taking the next central point D which is closest to the northmost central point A on the west side as a reference until the calculation process by taking the southerst central point as a reference is completed.
For example, the set distance in this step may be a range. Illustratively, when the above calculation process is performed, another center point having a set distance from the selected center point in the west-east direction is found by calculation within a certain range from north to south.
For example, if the calculated center point is assigned with the ID, the center point is skipped, the set distance is doubled, the calculation process is continued, and the set distance is restored to the original set distance after the next center point is found.
And from north to south, selecting another group of central points which are closest to the group of central points on the west side in the horizontal direction on the map, and repeating the calculation content in the steps.
And 2, inquiring whether the selected map has a central point which is not allocated with the identification ID, and if so, configuring a uniform identification ID for all the central points which are not allocated with the identification ID.
And 3, selecting a group of central points K1 with uniform identification IDs on the most north side, extracting the position coordinates of all the central points, selecting a group of central points K2 with the same identification IDs on the upper and lower groups of the map from north to south by taking the group of central points as a reference, calculating the position coordinates of all the central points in the group, inquiring whether the interval of the central points of the two groups of central points in the vertical direction is larger than a set value or not in a traversing calculation mode, and if the interval of the central points of the two groups of central points in the vertical direction is larger than the set value, adding the two groups of central points. And repeating the calculation process of the step 3 by taking the central point group K2 as a reference.
And if the interval between the central points of the two groups of central points K1 and K2 in the vertical direction is smaller than a set value, continuing to select the central points K3 with the same identification ID from north to south, repeating the calculation process in the step 3, and if the interval between the central points of the two groups of central points K1 and K3 in the vertical direction is larger than the set value, adding the two groups of central points K1 and K3 to one display cluster. And repeating the corresponding calculation process in the step 3 by taking the central point group K3 as a reference.
If the interval of the central points of the two groups of central points K1 and K2 in the vertical direction is smaller than a set value, after the calculation with the central point group K1 as the reference is completed, a new display cluster is allocated to the central point group K2, the corresponding calculation step in the step 3 is repeated with the central point group K2 as the reference, if the calculated central point group is already allocated to a certain display cluster in the calculation process, the central point group is skipped, and the subsequent calculation process is continued.
And 4, inquiring whether a central point group which is not distributed to the display cluster exists in the selected map, and if so, distributing all central point groups which are not distributed to the display cluster.
And 5, selecting any display cluster, and highlighting the area to which the building contained in the display cluster belongs and the attribute information matched with the area to which the building belongs.

And the data retrieval module 4 is used for receiving the retrieval information and generating a retrieval display cluster according to the retrieval information.
For example, the data retrieval module may provide a retrieval window, and may input information such as position coordinates and a feature name through the detection window, and by using the input retrieval data, the data retrieval module may query a display cluster including the information as a retrieval display cluster and display the retrieval display cluster in a cluster manner.
