[0397] The component setting function should be associated with the house entity. Only after selecting the house entity can the structure list pop up to select and set the structure type.

[0398] The parts list should have a single-select function to ensure that users can only select one structure type for setting.

[0399] The Finish button should have a save function to ensure that the set house structure type is saved.

[0400] The structural type of the annotation components should be displayed in real time on the drawing so that users can understand and identify the structural properties of these components.

[0401] Wall ownership:

[0402] The wall ownership function is used to set the ownership of building wall components separately in the mobile software of real estate title confirmation survey in rural areas.

[0403] Detailed functional requirements:

[0404] Specifically, it includes the distinction between owned walls, shared walls, and borrowed walls, which are automatically defaulted to owned walls. In the final generated results, owned walls are marked with three lines.

[0405] Owner:

[0406] The owner function is used to set the ownership of buildings in the mobile software for real estate title confirmation and investigation in rural areas. The head of household is the default right holder.

[0407] Parcel drawing:

[0408] Once all the houses are drawn in layers, you can proceed to the plot drawing process. At this stage, you can choose whether to inherit the sketch or the individual floor plans as the reference for the plot. Inherited plot plans cannot be moved.

[0409] Boundary setting:

[0410] Used to select and set the boundary points of a parcel on a map.

[0411] Detailed functional requirements:

[0412] Select a parcel: After clicking the boundary setting function, the software will prompt the user to select the parcel to be set. The user clicks the corresponding parcel on the map, and the system automatically confirms and proceeds to the next step.

[0413] Set Boundary Points: After selecting a parcel, the software automatically generates corresponding boundary point symbols at the parcel's boundaries, numbering them starting from the northwest corner (e.g., J1, J2, etc.). Users can set boundary point and boundary line information in the Boundary Settings dialog box.

[0414] Highlight entities: When users select or set boundary points on the map, the mobile terminal will automatically highlight the corresponding entities to help users confirm the accuracy of the selection and setting.

[0415] Set boundary points in sequence: The boundary setting dialog box provides Previous and Next buttons, and users can select boundary points in sequence and set them until all settings are completed.

[0416] Multiple parcel selection restrictions: To avoid misoperation, this function does not support multiple parcel selection. When the user attempts to select multiple parcels, the system will prompt the user that multiple parcels cannot be selected and automatically cancel the selection.

[0417] Automatic confirmation of settings: When the user completes the setting of a boundary point, the system will automatically confirm and enter the setting of the next boundary point.

[0418] Save settings: After all boundary points are set, the system will save all settings to the database for subsequent use.

[0419] Design considerations:

[0420] User experience: The design of the boundary setting function should take into account the user's operating habits and reading habits, and provide an intuitive and easy-to-use interface and an interactive method for highlighting entities.

[0421] Response speed: The application should have a fast response speed to avoid users waiting for a long time and improve the user experience.

[0422] Steps:

[0423] Click the [Boundary Setting] function, and a prompt will appear at the bottom of the page: [Please select the plot you want to set]

[0424] Select the corresponding plot on the drawing

[0425] The selection here only supports single selection of one parcel, not multiple selections. The software should automatically set it to only select the parcel layer to avoid misoperation.

[0426] After selecting a plot, click the [Finish] button. If multiple plots are selected, a prompt will appear saying that multiple plots cannot be selected, and the drawing selection will be canceled, ending the current command.

[0427] On the drawing, the corresponding boundary point symbols are automatically generated at the nodes according to the shape of the land parcel, and are numbered clockwise starting from the northwest corner, such as J1, J2...

[0428] At the same time, the dialog box of boundary setting pops up in the lower right corner of the page, and the boundary point and boundary line information are set. The default is to start from J1, and the boundary line is the boundary line of J1-J2. When setting the boundary line and boundary point information, the corresponding entity should be highlighted on the drawing at the same time.

[0429] The boundary setting dialog box provides the Previous and Next buttons. After setting a boundary point, you can click Previous or Next to continue setting until all settings are completed.

[0430] Boundary signature:

[0431] When the right holder or others take photos of the boundary and need to prove the ownership of the boundary, this function requires signature confirmation as supporting evidence.

[0432] Add four to:

[0433] After selecting the plot of land, mark the upper, lower, left and right sides of the plot of land.

[0434] Area calculation:

[0435] Allows users to set the area calculation coefficient for the house.

[0436] Detailed functional requirements:

[0437] Execute the area coefficient function: On the mobile device, the user opens the rural real estate title confirmation survey mobile software, enters the layered settings page, and selects the area coefficient setting option on the main interface.

[0438] Select House Parts: After entering the Layer Settings page, users need to select the house entity for which they want to set the area coefficient. House parts can be selected by clicking on them.

[0439] Set the area calculation coefficient of the component: Each house component has a default calculation coefficient. Click the > button of the corresponding floor to select the calculation coefficient of the floor and the component. Three coefficients are provided: full calculation, half calculation, and no calculation.

[0440] Complete the settings: After the settings are completed, the user can click the Finish button to save and upload the set floor information.

[0441] Functional design:

[0442] The floor selection box should have a multiple-selection function to support users to set floor information for multiple floors at the same time.

[0443] This function can only be used after the building settings have been made. The floor list is dynamically generated based on the set building number and the total number of floors of the building set in the property ownership collection and entry page.

[0449] Parcel location:

[0450] describe:

[0451] After the user completes the drawing collection, he can accurately locate the land parcel on the image page.

[0452] process:

[0453] After the user completes the drawing collection, the system should provide a portal to allow the user to enter the image page.

[0454] From the Imagery page, users should be able to trigger a parcel locate operation.

[0455] When the positioning operation starts, the system should start from other specified positions and obtain the positioning information of RTK or tablet.

[0456] You need to determine at least two points to define the location and orientation of the plot. The first point serves as the starting point of the plot, and the second point determines the orientation of the plot.

[0457] Based on the points specified by the user, the system should automatically calculate the exact location and orientation of the plot and visualize it on the image page.

[0458] Parcel location:

[0459] describe:

[0460] Users can manually adjust the position and orientation of located parcels.

[0461] process:

[0462] On the Imagery page, the user should be able to select a located parcel to make adjustments.

[0463] Once a parcel is selected, it should be highlighted.

[0464] The user should be able to move a parcel to a new location by dragging it. During the dragging process, the system should update the location of the parcel and display it in real time.

[0465] In addition to moving, users should also be able to adjust the orientation of the parcel. The system should provide a rotation function that allows users to rotate the parcel clockwise around the base point. Each rotation operation should rotate the parcel clockwise by a certain angle (e.g., 1 degree).

[0466] During the rotation process, the shape and size of the parcel should remain unchanged. Users can gradually adjust the orientation of the parcel by performing continuous rotation operations.

[0467] After the user completes the adjustment operation, the system should save the final position and orientation of the parcel.

[0468] Functional constraints and limitations:

[0469] The movement and rotation of the plot are based on the upper left corner point (reference point).

[0470] The rotation operation can only be performed 1 degree clockwise each time.

[0471] The shape and size of the parcel should remain unchanged during the move and rotation process.
