Detailed Description
The present disclosure will now be discussed with reference to exemplary embodiments, it being understood that the embodiments discussed are merely for the purpose of enabling those of ordinary skill in the art to better understand and thus practice the present disclosure and do not imply any limitation to the scope of the present disclosure.
As used herein, the term "comprising" and variants thereof are to be interpreted as meaning "including but not limited to" open-ended terms. The terms "based on" and "based at least in part on" are to be construed as "at least one embodiment.
Fig. 1 is a flowchart of an interaction method of an electronic map of an engineering project management system according to an embodiment of the present application, as shown in fig. 1, the interaction method of an electronic map of an engineering project management system includes:
in order to achieve the above object, the present application provides an interaction method for an electronic map of an engineering project management system, including:
acquiring a selected area according to the operation of a user in the map area;
based on the boundary coordinates of the selected region, the server acquires the subject information in the map region corresponding to the boundary coordinates;
determining the boundary of the candidate region based on the region boundary corresponding to the subject information, the boundary of the component in the geographic information model and the scaling factor of the map;
carrying out boundary compression on the boundary of the candidate region by using a Fabry-Perot algorithm to obtain a compressed region boundary;
rendering is performed in the electronic map area based on the compressed area boundary.
According to one embodiment of the present application, in the above-mentioned scheme, according to the operation of the user in the map area, a selected area is obtained; the operation of the user in the map area may be a mouse operation or an operation performed through a touch interface, where the operation forms a selection area on the electronic map interface, the selection area has a boundary, and the selection area may be sent to the server in the form of { x: y } array, where x represents a longitude offset, y represents a latitude offset, and a closed boundary expression may be:
{ "corodinates" [ [ [104.87124,27.290893], [104.871365,27.285269], [104.868307,27.278825], [104.869586,27.273822], [104.874547,27.264918], [104.880006,27.25853], [104.882221,27.257187] … ] ] }. The formed selection area can comprise label information of a user or does not comprise user-defined label information, and the label information of the user is a mark such as a 'first building', and the like and corresponds to a unique coordinate or shape; further, when the label of the user is stored at the server side, the content contained in the selection area can be directly obtained according to the selection area and the zoom level of the user without sending the coordinates.
According to one embodiment of the application, based on the boundary coordinates of the selected region, a server acquires subject information in a map region corresponding to the boundary coordinates; the step is to acquire Topic information in a user-side selected area, wherein Topic (Topic) is content defined by a user and associated with an engineering project, for example, a 6-level data structure included in the project of an industrial park is shown as follows, topic information is a label generated according to a Topic related to the project, for example, "project A-1 stage-chemical industry zone" and the like, in general, one Topic information corresponds to a unique area and stage in one engineering project, and in particular, the minimum Topic information of the project can change along with the progress of the project, for example, the boundary in the Topic information can change along with the progress; when the zoom level of the user is determined, theme information which can be presented can be determined based on the zoom level, and the specific corresponding relation is shown in the following table:
| level of | Theme | Attribute 1 | Attribute 2 | Attribute 3 |
| 1 | Project name | Responsible units | Start-up time | Boundary of |
| 2 | Project phase | Responsible units | Start-up time | Boundary of |
| 3 | ProjectPartition(s) | Responsible units | Start-up time | Boundary of |
| …… | …… | …… | …… | …… |
| 6 | Chamber | Responsible units | Start-up time | Boundary of |
According to one embodiment of the application, the boundary of the candidate region is determined based on the region boundary corresponding to the subject information, the boundary of the component in the geographic information model and the zoom magnification of the map; this step may be performed by traversing or based on a filter of components in the electronic map to obtain boundaries of the components or regions.
According to one embodiment of the application, the boundary of the candidate region is compressed by using a Fabry-Perot algorithm, so that a compressed region boundary is obtained; this process is to reduce the amount of data transferred and to optimize the display at the interface.
According to one embodiment of the application, rendering is performed in an electronic map region based on the compressed region boundaries; the rendering of the new boundary is similar to the construction of the map, i.e. the server generates scripts or executable data, e.g. json files containing coordinates, that can be executed at the client based on the boundaries processed by the previous steps, from which the client performs the rendering to re-determine the boundaries of the user selected area.
According to the method and the device, after the user selects the area, the problem of deviation between the selected content and the actual map and the problem of mismatching between the preset model and the map can possibly occur, the user can attach to object coordinates identified by the project model and the satellite map after selecting the area based on the method and the device, and the transparent layer gives the user better sense. The process is suitable for constructing a model, and due to deviation of a component presented by a semitransparent layer and a component on a map caused by data source or project change, for example, a suspended road appears, or a situation that the model of a building is positioned at the center of the map layer occurs, and when the situation occurs, for example, when a road and a road model label deviation is found through a road identification network, correction can be performed. The results of this correction may be saved to a database and the user may choose to view the original or disputed version as desired.
According to the embodiment of the application, the boundary data transmission quantity of the candidate area is too large, so that the boundary of the candidate area cannot be further rendered and operated in time, and therefore, after the boundary is compressed by the Wittig algorithm, the data transmission quantity is reduced in the boundary of the visual range, and the rendering step is further accelerated. In this way, the user operation area can be further determined, and the problems that the user operation content is not matched with the actual area and the operation area cannot be captured are avoided.
According to one embodiment of the application, the method is characterized in that visual components on the map are selected, the boundary coordinates of the selected area are compared with the outline coordinates in the visual components, the components with the coverage degree larger than a threshold value are obtained, and the hierarchical directory of the map is constructed based on the components with the coverage degree larger than the threshold value. In this way, a partly selected area can be obtained, for example when selecting green belts, which may be difficult for the user to find the target due to the image source situation, but in this way it can be selected in and a hierarchical directory is built, where the hierarchical directory is a navigation component of the subject information within the selected area, for example presented in the form of a tree or list.
According to one embodiment of the application, in the traditional map electronic interaction method, due to excessive operation on the map, a certain difficulty is generated in selecting some component customers, the main difficulty is that components cannot be selected accurately, some irrelevant components are selected incorrectly, the components are confirmed based on judgment of the threshold value and the visual outline to form a hierarchical directory, and a user needs hierarchical navigation related to a model, but the traditional hierarchical directory providing mode and model association degree are not high at present, so the application provides a method based on the threshold value and model association degree to construct, and the traditional defect is overcome.
According to one embodiment of the application, the compressed region boundaries include user entered boundary coordinates. In a common map interaction method, after the map is compressed, not only the size is often compressed, but also the boundary coordinates and the reference information provided by the user disappear. The inconvenience of the customer is caused, and after the user selects by the method of the application, the reference information provided by the user is reserved.
According to one embodiment of the application, the target ground object contained in the boundary coordinates of the area selected by the user is obtained according to the semantic recognition network, and the boundary coordinates of the area are obtained according to the coordinate information of the target ground object, wherein the target ground object comprises a building, a road, a greening, a water body, a soil covering area, geotextiles, a land block and other target ground objects with recognition values. Coordinates are determined on the map based on the boundaries of the non-model objects, and the boundaries are expanded based on the determined coordinates.
According to one embodiment of the application, when a selected area is acquired according to the operation of a user, whether the boundaries of the selected area and the actual building area are consistent is judged, and when the boundaries are inconsistent, the selected area is aligned to the actual building area.
According to one embodiment of the present application, the boundary of the candidate region further includes a label, and the candidate region corresponds to at least one label. In the traditional map interaction method, the map only has areas and lacks information labeling. The present application addresses this deficiency by providing tag information for objects of model and valuable semantics.
According to one embodiment of the application, when the candidate area contains a plurality of components, selecting the component with the largest size which can be displayed under the corresponding current scaling factor in the visible area; when the map comprises a plurality of components, messy information can occur, and reasonable region selection is determined according to the hierarchy and according to the configuration of the components with the largest size which can be displayed under the current zoom multiple.
And when the candidate area does not contain the components, acquiring the components with the largest size which can be displayed under the current scaling multiple in the visible area according to the association degree of the labels of the theme information. The map contains non-model content which cannot provide effective information, the effective information is identified according to the relevance, and the component with the largest size which can be displayed under the current scaling multiple is determined according to the relevance of the hierarchy.
According to one embodiment of the application, the electronic map includes a satellite map and an aerial image.

The formed selection area can comprise label information of a user or does not comprise user-defined label information, and the label information of the user is a mark such as a 'first building', and the like and corresponds to a unique coordinate or shape; further, when the label of the user is stored at the server side, the content contained in the selection area can be directly obtained according to the selection area and the zoom level of the user without sending the coordinates.

| level of | Theme | Attribute 1 | Attribute 2 | Attribute 3 |
| 1 | Project name | Responsible units | Start-up time | Boundary of |
| 2 | Project phase | Responsible units | Start-up time | Boundary of |
| 3 | Project partitioning | Responsible units | Start-up time | Boundary of |
