the segmentation also comprises surface segmentation, and the steps are as follows: the method is used for solving the superposition error between the two graphs; the result of the surface segmentation processing is that the selected cutting graphic object is used for cutting another graphic object, and the cut graphic object loses the overlapping part; the user selects the graph to be subjected to the surface segmentation operation by using the selection tool, clicks the surface segmentation tool, pops up a graph object window selected for cutting, and the selected graph is highlighted by filling color; then clicking a determining button to finish surface segmentation; the surface segmentation can also be used for carrying out island processing, and firstly, a user uses a drawing tool in a data acquisition module to draw a graph at a position needing island processing; then selecting two graphs, clicking a surface segmentation tool, popping up a graph object window selected for cutting, selecting a smaller graph, and clicking a determination button to complete segmentation;
the edge sharing step comprises the following steps: the user uses a selection tool to select one or more graphs needing to track the common edge, clicks the common edge tool, delineates the non-common edge part, and clicks the completion tool to complete the capture of the common edge; the user can also use a common edge tool to fill the graphs, and when one graph surrounded by a plurality of graphs is deleted by mistake, one graph can be drawn in a node capturing mode, but the operation is troublesome; the user can select all adjacent graphs by using the selection tool, then click the common edge tool, draw a common edge boundary, and then finish clicking to automatically fill up the two graphs; finally, combining the generated graphs into a graph by using a combination tool;
the steps of merging and scattering are as follows: the user selects a graph by using a selection tool, clicks the merging tool if merging is required, pops up a graph object interactive interface to which the attribute of the selected and merged graph object is attached, the user needs to select and reserve the attribute of the graph object as the attribute of the merged graph object, the selected graph object is highlighted by filling color, and then clicks to determine that graph merging is finished; the merging tool can also merge non-adjacent graphs, namely selected graphs are merged into a combined body; the scattering is used for recovering a graph set formed by combining a plurality of non-adjacent graphs into an independent graph;
the deleting, the canceling and the recovering steps are as follows: if the user wants to delete the geometric figure, the geometric figure to be deleted is selected, and the geometric object can be deleted by clicking the geometric figure to be deleted; if the user wrongly executes a certain editing operation, a cancel button can be clicked; if the user wants to recover the previous operation after the user cancels, the user can click a recovery button to recover.
2. The GIS data editing method according to claim 1, wherein:
the step S10), the selection of the geometric figure to be moved is completed by clicking one or more geometric figures with a finger, and the selected figure is highlighted on the screen after the finger click is determined.
3. The GIS data editing method according to claim 1, wherein:
and when the anchor point and the anchor point range appear in S11), the mobile terminal determines whether the operation of moving the graphic or editing the point, line, or plane is required.
4. The GIS data editing method according to claim 1, wherein:
the S13) is executed by the following procedure:
the mobile terminal judges that when the finger pressing position is not in the anchor point range, step S131) is executed;
s131) reselect a node in the graph as an anchor point.
5. The GIS data editing method according to claim 1, wherein:
the S15) is executed by the following procedure:
if the mobile terminal judges that the anchor point is close to other graph nodes; step S151) is executed, otherwise step S152) is executed;
s151) judging whether the anchor point is close to other graph nodes;
s152) the anchor point automatically captures the node.
6. The GIS data editing method according to claim 1, wherein:
the trimming operation comprises the following steps:
s20) click edit tool box
Clicking an editing tool box by using a finger to enter an editing operation;
s21) whether there is a selected geometric figure
Lifting the finger to click the geometric figure, if the geometric figure is selected by the finger, executing the step S30), otherwise, the editing tool cannot be used;
s22) clicking trimming tool
Clicking a trimming tool in the editing tool by a finger to execute trimming operation; when the trimming operation is executed, the mobile terminal draws a line passing through the selected geometric figure in a drawing mode; after the drawing is finished, clicking by a finger to confirm that the geometric figure is drawn;
s23) whether the drawing line intersects with the selected geometric figure
If the drawing line is intersected with the selected geometric figure, further judging whether the drawing line is intersected in the selected figure; otherwise, executing step S24);
if the drawing lines are self-intersected in the selected graph, executing the step S24); otherwise, replacing the shorter side of the selected graph with the drawing line, and then executing the step S25);
s24), finishing trimming, and rendering the current screen data
If the drawing line is not intersected with the selected geometric figure or the drawing line is intersected in the selected figure, clicking the trimming tool by a finger to finish the trimming operation; and performing rendering operation on the current screen data;
s25), finishing trimming, and rendering the current screen data
And clicking the trimming tool by a finger, finishing the trimming operation and rendering the current screen data.
