Fig. 1 is a flowchart of a method for splitting and analyzing historical cultural heritage map data according to an embodiment of the present application, and fig. 2 is a specific flowchart of a method for splitting and analyzing historical cultural heritage map data according to an embodiment of the present application, where the method for splitting and analyzing historical cultural heritage map data according to the embodiment of the present application may be implemented by a splitting and analyzing device based on historical cultural heritage map data, and the splitting and analyzing device based on historical cultural heritage map data may be implemented by software and/or hardware, and the splitting and analyzing device based on historical cultural heritage map data may be formed by two or more physical entities, or may be formed by one physical entity. In general, the shunt analysis device based on the historical cultural heritage map data can be a computer, a mobile phone, a tablet or a background server and the like.
The following description will be made taking a background server as an example of an apparatus for performing a shunt analysis method based on historical cultural heritage map data. Referring to fig. 1 and 2, the method for analyzing the map data of the historic cultural heritage specifically includes:
s101: planning data input by a user is received.
The planning data can be obtained by positioning coordinate point data collected on site in real time, can be fixed point coordinates clicked by operation on a system and scribing data of operation sketching, and can also be obtained by obtaining coordinate data stored in a configuration file by a user; the planning data are all performed on the space map data of the historical cultural heritage of the characteristic region. Namely, the superposition object and the buffer area object are constructed by inputting accurate coordinates, or the superposition object and the buffer area object are delineated on a map by a mouse. For example, the user needs to plan a protection area based on a palace and a palace street, and can collect surrounding cultural site information first and then upload the collected data. FIG. 3 is a schematic view of a planning display performed based on historical cultural heritage according to an embodiment of the present application; the map comprises a planning superposition area, a buffer area and a historical cultural heritage protection area; and also shown in fig. 3 are analysis result points, which are overlapping points between the regions.
In this embodiment, the input planning data, the corresponding planning data is marked with the superimposed data and the buffer data. For example, when planning data is defined, if the control is manually operated on software, the control is selected to be superposition analysis, then position data on a map layer is clicked as the planning data, when a certain map area is reached, whether the point is suitable for superposition is unclear, the control is selected to be buffer analysis, and position data needing to be buffer analysis is selected at the position of the map area in a mode of selecting a point, a line and a plane. And then continuing to select the superposition area, and defining superposition position data. Each of the operations described above forms superimposed data and buffer data, which are collectively referred to as planning data.
In this embodiment, the superposition analysis is performed on the superposition data to perform the planning operation on the newly added protection range, the control line, and the like, and the buffer analysis is performed to obtain the spatial relationship between the planning area and the existing planning area, and different level boundaries are set based on the spatial relationship, so that the buffer analysis belongs to the pre-judgment auxiliary operation.
S102: and classifying the planning data to obtain superposition data and buffer zone data, and determining a superposition transmission path and a buffer zone transmission path according to the superposition data and the buffer zone data.
Specifically, corresponding configuration information of the planning data is obtained, the planning data is classified according to the configuration information to obtain superposition data and buffer zone data, and different shunt transmission paths are defined according to different types of data. Even if the superimposed data is transmitted to the addition transmission path, the buffer data is transmitted to the buffer transmission path.
S103: and transmitting the superimposed data to the superimposed data branch according to the superimposed transmission path, and transmitting the buffer data to the buffer data branch according to the buffer transmission path.
The step mainly comprises the steps of transmitting the superimposed data to a corresponding superimposed data shunt and transmitting the buffer data to a corresponding buffer data shunt, wherein the buffer analysis and the superimposed analysis belong to two different types of data analysis, so that the two are positioned at different analysis shunt positions, and the data are required to be transmitted according to different transmission paths. By setting two different analysis branches, superposition analysis and buffer area analysis are performed simultaneously, so that analysis time consumption is reduced for a user.
S104: and triggering an analysis instruction of the superimposed data in the superimposed data shunt to obtain a corresponding superimposed analysis result, and triggering an analysis instruction of the buffer data in the buffer data shunt to obtain a corresponding buffer analysis result.
The method mainly aims at realizing specific superposition analysis and buffer area analysis, wherein the superposition analysis comprises five analysis types, namely visual information superposition, point-polygon superposition, line-polygon superposition, polygon superposition and raster layer superposition. The above five types of superposition analysis indicate that the superposition data contains data types, and the superposition analysis is mainly used for performing planning operations on newly added protection ranges, control lines and the like.
Buffer analysis is a spatial analysis tool used to solve the proximity problem. Proximity describes how closely two features are in geographic space. The following categories are used: 1. the buffer area based on the point elements is generally a circle with a certain distance as a radius around a point. 2. The buffer region based on line elements is generally a parallel stripe polygon having a line as a central axis and a distance from the central axis. 3. The buffer based on the face element polygon boundary expands a distance outward or inward to generate a new polygon. And obtaining the spatial relationship between the planning area and the existing planning area through buffer area analysis, setting different grade boundaries based on the spatial relationship, and further confirming different protection boundaries.
More preferably, fig. 4 is a schematic flow chart of performing superposition analysis on buffer data at superposition data branching, which includes:
s1041a: if an instruction for carrying out superposition analysis on the buffer area data exists, the corresponding buffer area data is called;
s1041b: performing superposition analysis on the superposition data and the buffer zone data to obtain a superposition analysis result;
s1041c: and determining whether to perform buffer analysis according to the received feedback instruction, and if so, sending corresponding superimposed data to a buffer data shunt to perform buffer analysis.
The above-mentioned is mainly for judging whether there is an instruction for performing superposition analysis on the buffer data, where the buffer data and the superposition data are position data which are planned in advance and marked with operation types. When the superposition analysis branching is performed, the normal superposition data is subjected to superposition analysis, the main road determines to perform superposition analysis or buffer analysis after analyzing the planning data, and the corresponding analysis object is transmitted to the analysis branching. When the non-pure superposition data or the non-pure buffer data is present, that is, when both superposition data and buffer data are present and planning data to be subjected to superposition analysis operation is present, it is determined whether the buffer data is also subjected to superposition analysis. Essentially, the difference between the superimposed data and the buffer data is the position data, except for the label and the effect which are defined in advance. Therefore, it is also possible to realize the superimposition analysis of the buffer data and the buffer analysis of the superimposition data.

s1042c: and determining whether superposition analysis is performed according to the received feedback instruction, and if so, sending corresponding buffer data to a superposition data shunt to perform superposition analysis.
The above is mainly to determine whether an instruction for performing buffer analysis on the superimposed data exists, and as described above, when the superimposed data is non-pure buffer data, it is necessary to determine whether to perform corresponding buffer analysis on the superimposed data. If the buffer area analysis function control is selected in the process of superposition operation in the planning data so as to know whether the position area establishes a protection area or the planning building area is proper, the buffer area data exists in the superposition operation background, and a user can be inquired whether the buffer area is used as a superposition area for superposition analysis in superposition branching or not, or parameters set by the user in advance are directly called to carry out superposition analysis on the buffer area as the superposition area. After the superposition analysis is completed, the presentation mode can be to divide the superposition area on the map based on the analysis result data, inquire the user whether the superposition analysis is completed and then carry out the buffer analysis, or call a program set by the user in advance, and if the buffer analysis is required, distribute the superposition data to the buffer area to carry out the buffer analysis. Similarly, in the case of buffer branching analysis, it is judged whether or not the allocated superimposed data requires buffer analysis. In this embodiment, the superposition analysis and the buffer analysis can achieve the coexistence and interconversion effects, and can achieve the simultaneous parallel analysis of the two, thereby improving the analysis efficiency.

s100b: and loading the boundary data of the historical cultural heritage of the specific area.
The boundary data, namely, the boundary data, in the historical cultural heritage space map data in the specific area is loaded, and a specific program is exemplified as follows:
s100c: and rendering the map data according to the boundary data to form a corresponding map layer, and adding the map layer to the map data to obtain the spatial map data of the historical cultural heritage.
Fig. 11 is a schematic display view of spatial map data of historic cultural heritage provided in the embodiment of the present application, as shown in fig. 11, which only shows a schematic view of loading display effects. In this embodiment, the body includes a historical town area, a historical cultural name street, a village and a ancient post, and the protection range includes a key protection planning area (a high-voltage circuit area, a railway dredging area, etc.), an underground protection resource, etc. The building control zone refers to administrative planning control protection building zones (national administrative, military, other non-architectural infringement control zones, etc.). The method comprises the following specific steps: the Geoprocessing module issues a shp data searching command, invokes the boundary data through a storage space corresponding to the specific path, loads the shp data into map data, forms a first layer, a second layer, a third layer and the like through rendering according to different boundary data, and is overlapped on a map data base layer together, and when certain boundary data is not needed, the shp data can be selectively removed. The map data based on the above can be used by the user to determine the analysis object for the planning data (the coordinates of the positioning coordinate point collected on the spot in real time, the coordinates of the fixed point clicked by the operation on the system, and the drawing data of the operation drawing) of the space map data of the historical cultural heritage of the specific area.
In this embodiment, planning data is input, and operations performed by the main path analysis and judgment planning data are respectively tuned into corresponding superposition branches and buffer area branches. And the positions of the pure superposition identification and the superposition function are only subjected to superposition analysis operation in a superposition shunt, and the data in the pure buffer area are the same. If the buffer area analysis function control is selected in the process of the superposition operation to know whether the protection area is built in the position area or the planning building area is proper, buffer area data exists in the superposition operation background, and a user can be inquired whether the buffer area is used as the superposition area for superposition analysis or whether the buffer area is used as the superposition area for superposition analysis by directly calling parameters set by the user in advance. After the superposition analysis is completed, the presentation mode can be to divide a corresponding superposition area on the map based on analysis result data, inquire whether a user performs buffer area analysis after the superposition analysis is completed or call a program preset by the user, and if the buffer area analysis is required, distribute the superposition data to a buffer area for buffer area analysis. Similarly, when the buffer is branched, it is judged whether or not the allocated superimposed data is true to be buffer analyzed. The superposition analysis and buffer analysis in this embodiment can achieve the coexistence and interconversion effects.
In the current historical cultural heritage protection technology of geographic information, no parallel path is used for simultaneously carrying out superposition analysis and buffer analysis in regional division planning protection work of map data, but the scheme of parallel path simultaneous analysis is provided in the invention, and the superposition analysis and buffer analysis are carried out simultaneously by setting up independent analysis branches. And the special map data analysis object of the historical cultural heritage is utilized, and the adoption of the analysis scheme with strong compatibility and humanization and intelligence can be adjusted, so that the working efficiency is effectively improved, and the assistance is provided for the division of the protection areas and the evaluation of the protection grades of the historical cultural heritage. In the aspect of realizing the superposition analysis and buffer area analysis technology, when the superposition analysis and the buffer area analysis are performed to adapt to the double-path parallel connection, the analysis time is more than that of one-path analysis, but compared with the mode of separately performing data processing on the superposition analysis and the buffer area analysis, the scheme of the method and the device for processing the data is less in time and can present more perfect analysis content.
Aiming at the establishment of a historic cultural heritage protection area, the scheme can realize two paths of analysis operations at the same time, and the effect of superposition analysis execution is to increase an effective protection area and standardize the establishment of a protection control line range; the buffer area analysis execution effect is to find the historical cultural heritage region risk area, establish the protection line range and conduct hierarchical protection.
