Referring to fig. 1, fig. 1 is a flowchart of a method for generating a planned land measurement result according to an embodiment of the present application, including:
S101: and enclosing the land by using the land boundary line.
Land border calculation is an important step in urban planning, which involves how to determine and calculate the range of individual plots. As shown in fig. 2, fig. 2 is a plot of land boundaries according to an embodiment of the present application, and after the calculation of the land boundaries is completed, all the obtained broken entities of the land boundaries are broken entities, where the broken entities include line segments or arcs.
In some embodiments, the broken-up entities of the block boundary line are now broken into basic units, which include line segments or arcs, then the intersection points of all intersecting line segments or arcs are determined, and the intersection points are used to break the intersecting line segments or arcs into line segments or arcs again. Then, all the coincident line segments or arcs are deleted so that only one line segment or arc remains at the same position. And traversing all the line segments or arcs to delete the line segments or arcs with the isolated points to obtain a target basic unit, wherein the target basic unit comprises the line segments or arcs without the isolated points. In this way, the target base unit may be utilized to enclose the parcel.
Based on the foregoing embodiments, the specific manner of enclosing the land block with the target base unit may be as follows: marking the use times of the line segments or the circular arcs in the target basic units as 0, and then starting from any one endpoint of the line segments or the circular arcs in any basic unit, and searching the line segments or the circular arcs connected with the endpoint from the line segments or the circular arcs with the use times less than 2. If only 1 line segment or arc connected with the end point is found, continuing to find the next line segment or arc from the other end point of the found line segment or arc.

Therefore, a closed figure can be constructed by utilizing the line segment or the arc which is searched in any target basic unit, and the closed figure is used as a land block.
After constructing a closed graph by using the line segments or the circular arcs searched by the line segments or the circular arcs in any target basic unit, the rotation direction of each closed graph can be judged, and if the rotation direction of the closed graph is left-handed, the closed graph is abandoned; if the rotation direction of the closed figure is right rotation, the closed figure is reserved, and the number of times of using the line segments or the circular arcs forming the closed figure is increased by 1. And repeating the searching step until the using times of all the line segments or the circular arcs are larger than 0. Then, all the closed graphs are initialized, wherein the initialization method comprises the steps of, but is not limited to, calculating the area of the closed graphs, judging and recording the nesting relation of the closed graphs, calculating an internal point for each closed graph, and using serial numbers as the initial name of each closed graph respectively.

The attribute of a land block can also be set independently by using a click setting tool, and the click setting is realized in the following way: firstly, the set attribute information of the land is read, one coordinate point in the land is input, finally, all the land is traversed, and if the coordinate point is positioned in a certain land, the attribute is set to the land.
In some embodiments, the block attribute information in the planning information is hooked to the block, and specific embodiments include: sequentially hitching and selecting hitching. Before the land parcel attribute information in the planning information is hung on the land parcel, the planning information is read, wherein the specific mode for reading the planning information is as follows: the data structure of the json file is analyzed, a class is created by using the structure, and then an instance of the class is acquired by using an inverse serialization method, wherein the attribute of the instance is planning condition information in the json file, and the json is in a lightweight text-based readable format.
The specific mode of sequential hanging is as follows: firstly, taking out the attribute information of the land parcels in the planning conditions according to the sequence, then inputting the coordinates of one point inside the land parcels to be set, traversing all the land parcels, setting the attribute information into a certain land parcels if the point is positioned inside the land parcels, and then repeatedly taking out the attribute information of the next land parcels to be hung until the process is finished.
The specific mode of selecting the hanging is as follows: selecting a land block to be hung from the land list, automatically reading attribute information of the land block, inputting coordinates of a point inside the land block to be set, traversing all the land blocks finally, and setting the attribute information to a certain land block if the point is inside the land block.

The direct modification in the parcel list is as follows: the parcel names displayed in the parcel list are bound with parcel names, and the parcel names in the parcel list are directly edited to modify the parcel name attribute values. When the land block attribute in the planning condition is hooked, the planning name of the land block is also hooked into the land block attribute.

The subsequent plots repeat the naming method of the first plot until the naming of the boundary points of all plots is completed.
The designating the point number includes a method of manually designating the point number, importing the point number from an external file, reading the point number from a screen, and the like. The method for manually designating the point number is as follows: the method comprises the steps of inputting a point number from a command line, inputting coordinates of the point, and finally checking whether the point number is used or not or whether the coordinates are assigned with the point number, if a problem exists, popping up a prompt, and if the problem exists, recording the point number into a list. The method for realizing the import of the point number from the outside comprises the following steps: editing the point numbers into coordinate files according to a specified format, reading the files, analyzing the point coordinates and the point numbers, and recording the point coordinates and the point numbers in a point number list. The method for reading the point number from the screen is as follows: firstly, drawing a point number as a text entity, placing a locating point of the entity at the position of a standby name point, wherein the content of the text is the point number, then placing the text entity into a designated layer, wherein the layer does not have other entities irrelevant to the point number, finally, acquiring the set point number entity, extracting the content and locating point coordinates, and filling the content and locating point coordinates into a point number list for recording.
