Further, as a refinement and an extension of the specific implementation of the above embodiment, in order to fully explain the specific implementation process of the embodiment, another method for editing a history map is provided, as shown in fig. 2, the method includes:
step 201, responding to a land parcel cutting instruction, and outputting a land parcel cutting tool, wherein the land parcel cutting tool is a polygonal frame with a changeable shape;
in the embodiment of the present application, the parcel cutting tool may include a plurality of polygon frames of different shapes, and the parcel cutting tool is provided in response to a parcel cutting instruction for a user to select a desired polygon frame from the polygon frames, so that the parcel to be cut and the cutting line are selected by using the polygon frames by moving the positions of the polygon frames, scaling the polygon frames, stretching a vertex of the polygon, and the like.
202, receiving a selected position of a polygonal frame, determining a cutting line according to the position of any side and determining any plot as a plot to be cut when any side of the polygonal frame is intersected with any plot of the target historical map and other sides of the polygonal frame are positioned outside the range of any plot;
in step 202, an operation of the user on the polygonal frame is received, a selected position of the polygonal frame is obtained, as shown in fig. 3, a schematic diagram of an example of cutting a land parcel is shown, an edge line of a cutting surface corresponding to an area where a land parcel to be cut intersects with the cutting surface is a cutting line, the user can select a single land parcel or a plurality of land parcels to be cut first, the cutting surface is drawn by moving a polygonal frame selecting tool based on the selected area, when the cutting surface is drawn, the cutting line area intersects with the land parcel to be cut, and other edge lines of a non-cutting line in the polygonal frame need to exceed the range of the land parcel, so that abnormal cutting is avoided, and the cutting accuracy is improved.
in step 203 and step 204, first vector data corresponding to a to-be-cut parcel selected by a user and a corresponding first parcel identification are obtained, where the first parcel identification may be a number, a character string number, or the like, which can be used to distinguish the parcel from other parcels, further, second vector data is determined according to the first vector data and a cutting line, and a second parcel identification corresponding to the second vector data is generated according to the first parcel identification, where the second parcel identification is generated based on the first parcel identification, that is, the cut parcel retains an association relationship with the first parcel identification according to an identification generation rule, for example, the first parcel identification is a, and the second parcel identification may be a-1, a-2, so that a new parcel generated by cutting may inherit parcel resource information based on an identification association relationship with an original parcel.
In this embodiment, specifically, the second vector data is used to realize the re-cutting of the land parcel to be cut.
In the above embodiment, after a user cuts a certain to-be-cut parcel, if the parcel needs to be cut again, the cutting may be performed directly based on the second vector data corresponding to the parcel, for example, after the parcel a is cut into two parts, i.e., a part a-1 and a part a-2, the cutting may also be continued on the parcel a-1 and the parcel a-2, and since the parcel tile data corresponding to the tile data map layer of the target historical map is still matched with the parcel a, when the parcel a-1 and the parcel a-2 are cut, the cutting may be performed directly based on the vector data map layers corresponding to the parcel a-1 and the parcel a-2, i.e., the cutting of the parcel a-1 and the parcel a-2 is realized based on the second vector data. The second vector data are utilized to realize the secondary cutting of the plot to be cut, the second vector data corresponding to the vector data map layer are not required to be converted into tile data, the secondary cutting of the plot to be cut can be realized, and the map editing efficiency is improved. It should be noted that, in order to facilitate the inheritance of the parcel resource data, the parcel identification corresponding to the new parcel data obtained by cutting based on the second vector data is also kept associated with the first parcel identification, for example, the parcel identification of the new parcel obtained by cutting parcel a-1 may be a-3, a-4, or a-1-1, a-1-2, etc.
Step 205, responding to a cutting reset instruction corresponding to the to-be-cut land, deleting the second vector data, and re-acquiring the to-be-cut land and the cutting line corresponding to the target historical map;
in step 205, if the user is not satisfied with the selected position of the polygon frame, the block is cut again by issuing a cutting reset command, and in response to the cutting reset command corresponding to the block to be cut, the second vector data and the second block identifier obtained based on the original block to be cut and the cutting line are deleted, and the edit data of the user on the target history map is continuously obtained, that is, the block to be cut and the cutting line corresponding to the target history map are obtained again. The user may re-determine the parcel to be cut and the cut lines by re-selecting the polygon frame, re-determining the polygon frame, etc.
in step 206, after the second vector data is determined, the vector data layer of the target history map is determined based on the second vector data corresponding to the new block generated by cutting the block to be cut, and the vector data layer is placed on the top layer of all layers of the target history map, so that the target history map can exhibit the latest cutting effect.
Step 207, sending a target historical map updating instruction to a client corresponding to the target historical map platform, wherein the target historical map updating instruction comprises a vector data map layer, and the target historical map updating instruction is used for controlling the client to be offline from the target historical map platform and outputting a new target historical map based on the vector data map layer when the client is online again;
in step 207, after the block of the target historical map is cut, in order to display the editing result on the client in time, a target historical map updating instruction may be generated and sent to the client corresponding to the target historical map platform, the target historical map updating instruction may be generated based on the vector data map layer, the instruction carries the vector data map layer, and after the client receives the target historical map updating instruction, in order to maintain the synchronization of the target historical map, the client may force the platform user to go offline, and update the target historical map according to the vector data map layer, so that the latest target historical map can be displayed when the client user goes online again.
step 209, if the current target tile data exceeds the preset threshold, acquiring target tile data corresponding to all the vector data and second place identifications corresponding to all the vector data respectively, and updating the target tile data based on all the vector data and the second place identifications so that the updated target tile data is matched with all the vector data and the tile identifications corresponding to the updated target tile data are matched with the place identifications;
and step 210, removing the vector data layer corresponding to the target historical map.
In steps 209 to 210, in order to avoid affecting the performance of the editor after the cut vector data is continuously incremented, the editing background may detect the number of the cut land blocks at regular intervals, if the number exceeds the threshold, start the processing flow of vector conversion tiles, and after the tile conversion is completed, delete the temporarily generated vector layer, and update the land blocks into the cut data.
