Furthermore, in the following detailed description, numerous specific details are set forth in order to provide a better understanding of the present disclosure. It will be understood by those skilled in the art that the present disclosure may be practiced without some of these specific details. In some instances, methods, means, elements and circuits that are well known to those skilled in the art have not been described in detail so as not to obscure the subject matter of the present disclosure.
Fig. 1 shows a flowchart of a geographic element data processing method according to an embodiment of the present disclosure, as shown in fig. 1, the method including:
in step S11, determining a target geographical element that changes according to the change attribute values of a plurality of geographical elements in the geographical elements of the preset area;
in step S12, updating a geographic element database according to the type of the target geographic element to obtain an updated geographic element database, wherein the type of the target geographic element includes at least one of an area geographic element, a road geographic element, and a water area geographic element;
in step S13, determining geographic information of the preset area according to the updated geographic element database, where the geographic information includes map information of the preset area.
According to the geographic element data processing method disclosed by the embodiment of the disclosure, the changed geographic element can be determined according to the change attribute value, the geographic element database is updated according to the type of the changed geographic element, the possibility that the geographic element is classified wrongly is reduced, and the geographic information can be determined based on the updated geographic element database, so that errors such as geographic element overlapping are reduced, and the accuracy of the geographic data is improved.
In a possible implementation manner, the geographic element data (which may include, for example, city territory space key element data) may include a plurality of geographic elements, and the number of the geographic elements is large, and the geographic elements have a specific positional relationship with each other, so that, for a change of the geographic elements, the recognition difficulty is large, and an error may occur.
In one possible implementation, the geographic element data may be surface coverage data comprising a plurality of geographic elements, which may be acquired by a mapping agency and obtained through a quality inspection acceptance. The surface coverage data may have a canonical format and a standard data structure to facilitate data processing.
In one possible implementation, in step S11, a target geographic element of the change in the surface coverage data may be determined. In an example scenario, preprocessing of entering of city homeland space key element data can be achieved. In an example, the surface coverage data may be surface coverage data of a preset area, for example, surface coverage data in a certain city. A variety of geographic elements may be included in the surface coverage data from which a target geographic element that has changed may be determined. For example, the obtained surface coverage data may be compared with the raw data in the geographic element database to determine the target geographic element that has changed. In another example, as described above, the format specification, data structure standard, of the surface coverage data, and thus the target geographic element may be determined from a particular type of data in the surface coverage data.
In one possible implementation, step S11 may include: determining a first geographical element which changes according to the change attribute value; determining a relationship between the first geographic element and a second geographic element adjacent to the first geographic element; and determining the target geographic element according to the relation.
In one possible implementation, each geographic element may have multiple attribute values, which may include a change attribute value, for example, in the standard surface coverage data, the change attribute value may include attribute values such as ChangeType and ChangeAtt, which are used to indicate information such as the type and manner of change of the geographic element. Therefore, the geographic elements that change can be screened among the plurality of geographic elements by the change attribute value.
In an example, a geographic element with ChangeType =2 and/or ChangeAtt containing a specific field code may be selected as the first geographic element that changes from among the plurality of geographic elements contained in the surface coverage data.
In one possible implementation, a relationship between a first geographic element that has changed and a second, adjacent geographic element may be determined. In an example, it is determined whether a first geographic element and an adjacent second geographic element would be the same geographic element. For example, if the first geographic element and the adjacent second geographic element belong to the same entity, the first geographic element and the second geographic element are the same geographic element, for example, the first geographic element is a road, the second geographic element is also a road, and the changed first geographic element is a geographic element obtained by extending the original road. For another example, if the first geographic element and the adjacent second geographic element do not belong to the same entity, the first geographic element and the second geographic element do not belong to the same geographic element, for example, if the second geographic element is a scenic spot and the first geographic element is a building, the changed first geographic element may be a newly added (newly built) building or the like.
In one possible implementation, after determining the relationship between the first geographic element and the second geographic element, the target geographic element may be determined based on the relationship.
In one possible implementation, determining the target geographic element according to the relationship includes: and determining the geographic elements to which the first geographic element and the second geographic element belong as the target geographic element when the first geographic element and the second geographic element belong to the same geographic element.
In a possible implementation, if the first geographic element and the second geographic element belong to the same geographic element, i.e. belong to the same entity, the same entity to which the first geographic element and the second geographic element belong may be determined as the target geographic element of the change. And the first geographic element and the second geographic element may be assigned the same attribute value.
In an example, the first geographic element is a road, the second geographic element is also a road, and the changed first geographic element is a geographic element obtained by extending an original road. In this example, the whole of the road to which the first geographic element and the second geographic element belong may be regarded as the changed target geographic element.
In one possible implementation, determining the target geographic element according to the relationship includes: determining the first geographic element as the target geographic element if the first geographic element and the second geographic element do not belong to the same geographic element.
In one possible implementation, if the first geographic element and the second geographic element do not belong to the same geographic element, the first geographic element is an independent whole, and the changed first geographic element itself may be determined as the target geographic element. And different attribute values may be assigned to the first geographic element and the second geographic element.
In an example, the second geographic element is a scenic spot, the first geographic element is a building, and the changed first geographic element may be a newly added (built) building, etc. In this example, the newly added building is independent from the scenic spot, and therefore, the first geographic element (newly added building) itself can be determined as the target geographic element that has changed.
In one possible implementation, after determining the target geographic element, the geographic element database may be updated in step S12 based on the type of the target geographic element, and the updated geographic element database is obtained.
In one possible implementation, the type of the target geographic element includes at least one of a regional geographic element, a road geographic element, and a water geographic element. The regional geographic elements can comprise geographic elements occupying a certain region, such as buildings, scenic spots, tourist areas, town integrated function units and the like. The road geographic elements may include geographic elements such as railways, highways, and the like. The water area geographic elements can comprise river, lake and other water area geographic elements. The geographic element database may be updated in different ways for different geographic element types, respectively.
In one possible implementation, for regional geographic elements, step S12 may include: for the regional geographic elements, acquiring geometric center points of the regional geographic elements; and updating the geographic element database according to the geometric center point to obtain an updated geographic element database.
Fig. 2 is a schematic diagram of regional geographic elements according to an embodiment of the present disclosure, and as shown in fig. 2, two target geographic elements are both regional geographic elements, and a geometric center point of the target geographic element after change can be obtained. For example, if the shape or area of the regional geographic element changes (e.g., a certain scenic spot is enlarged), the geometric center point of the regional geographic element can be retrieved and the original geometric center point can be deleted. If the regional geographic element is newly added (for example, a newly added building), the geometric center point of the regional geographic element can be directly obtained. In an example, the geometric center point can also be used as a geographic element and assigned a specific attribute value, for example, the IFDERIVED value is assigned to 1, and the present disclosure does not limit the type and specific value of the attribute value.
In one possible implementation, the geographic element database may be updated according to the geometric center, for example, the updated geometric center (e.g., a new geometric center replacing the original geometric center and/or a new geometric center) may be extracted to the data layer storing the geometric center element, and the data layer may be used to replace the data layer storing the geometric center element in the geographic element database. The manner in which the geographic element database is updated is not limited by this disclosure.
In one possible implementation, for the road geographic element, step S102 may include: for the road geographic elements, acquiring at least one of road arc sections, road nodes, road obstacle points and road identification information; and updating the geographic element database according to at least one of the road arc segment, the road node, the road obstacle point and the road identification information to obtain an updated geographic element database.
In one possible implementation, the geographic elements of roadways may include, for example, geographic elements of highways, railways, and the like. The geographical elements such as the road, the railway and the like can comprise at least one element of road arc sections, road nodes, road obstacle points and road identification information.
In an example, a road arc, e.g., a path of a railway, may be included in the railway geographic elements, a changed target geographic element, e.g., a changed arc in a railway arc, may be obtained in a data layer of the railway (e.g., a railway data layer identified as V _ LRRL), and a new railway arc may be generated based on the changed arc and updated to a corresponding data layer, e.g., a data layer identified as N _ LRRL, and the changed arc may be assigned a particular attribute value. Further, the changed target geographic element, for example, the changed arc segment, may also be extracted to the data layer for storing the changed geographic element, for example, the data layer identified as UV, for example, the newly added arc segment, the changed arc segment, the situation that the original arc segment is interrupted, and the like may all be extracted to the data layer identified as UV. And when determining the changed arc segment, determining whether the changed arc segment and the adjacent arc segment are the same arc segment, if the changed arc segment and the adjacent arc segment belong to the same arc segment, using both the changed arc segment and the adjacent arc segment as changed target geographic elements, in other words, determining connectivity between the changed arc segment and the adjacent arc segment, and if the changed arc segment is communicated with the adjacent arc segment, using both the changed arc segment and the adjacent arc segment as target geographic elements and extracting the target geographic elements to a data layer marked as UV.
In an example, the railway geographic elements may include road nodes, which may include the start point, midpoint, connection point, bifurcation point, intersection, etc. of an arc segment, e.g., a train station, etc. The road nodes such as train stations may be obtained from a data layer holding road nodes (e.g., a data layer identified as UV _ BUCP), and the road nodes that have changed may be saved to a data layer recording changes in road nodes, e.g., a data layer identified as UN _ LRRP.
In an example, the railway geographic elements may include road obstacle points, which may include road obstacle points such as railroad bridges, tunnels, train crossing points, and the like. The road barrier point may be acquired from a data layer in which the road barrier point is stored (for example, a data layer identified as UV _ SFCL), and the road barrier point in which the change has occurred may be stored into a data layer in which the change in the road barrier point is recorded, for example, a data layer identified as UN _ LRBP.
In an example, the railway geographic element may include road identification information, the road identification information may include a position where the identification information such as a road signal lamp is located, and the changed road identification information may be determined and saved to a corresponding data layer.
In one possible implementation, specific attribute values may also be assigned to the road arc, road NODEs, road obstacle points, road identification information, etc., which have changed as described above, for example, attribute values identified as NODE _ ID, START _ NODE _ ID, and/or END _ NODE _ ID for road NODEs, attribute values identified as LINK _ ID for road arcs, attribute values identified as NODE _ ID for road obstacle points, etc. The present disclosure does not limit the identification.
In one possible implementation, the road geographic element may also include a highway geographic element.
In an example, the geographical elements of the roads may include road arcs, e.g., paths of roads, the changed target geographical elements in the road arcs of railways may be obtained at a data layer of the roads (e.g., a road data layer identified as V _ LRRL), new road arcs may be generated based on the changed arcs and updated to a corresponding data layer, e.g., a data layer identified as N _ LRRL, and the changed arcs may be assigned specific attribute values. Further, the changed target geographic element, for example, the changed arc segment, may also be extracted to the data layer for storing the changed geographic element, for example, the data layer identified as UV, for example, the newly added arc segment, the changed arc segment, the situation that the original arc segment is interrupted, and the like may all be extracted to the data layer identified as UV. And when determining the changed arc segment, determining whether the changed arc segment and the adjacent arc segment are the same arc segment, if the changed arc segment and the adjacent arc segment belong to the same arc segment, using both the changed arc segment and the adjacent arc segment as changed target geographic elements, in other words, determining connectivity between the changed arc segment and the adjacent arc segment, and if the changed arc segment is communicated with the adjacent arc segment, using both the changed arc segment and the adjacent arc segment as target geographic elements and extracting the target geographic elements to a data layer marked as UV. Further, in determining the road arc, connectivity between different roads, for example, whether the crossed roads are connected (for example, two roads are not connected when crossing at the position of the overpass), and/or connectivity between different levels of roads, for example, connectivity between urban roads and rural roads, etc., may also be determined, and the connectivity between the roads is indicated by a specific identifier.
In an example, the highway geographic elements may include road nodes, which may include start points, midpoints, connection points, bifurcation points, intersections, and the like of arcs, e.g., bus stops, toll booths, checkpoints, and the like. The road node may be obtained from a data layer in which the road node is saved (e.g., a data layer identified as UV _ SFCP), and the road node having the change may be saved to a data layer in which the change of the road node is recorded, e.g., a data layer identified as UN _ LRDP.
In an example, the highway geographic elements may include road obstacle points, which may include road obstacle points such as highway bridges, tunnels, automobile crossing points, and the like. The road obstacle point may be acquired from a data layer in which the road obstacle point is stored (for example, a data layer identified as UV _ SFCL), and the road obstacle point that has changed may be stored into a data layer in which the road obstacle point that has changed is recorded, for example, a data layer identified as UN _ LDBP.
In an example, the road geographic element may include road identification information, the road identification information may include a position where the identification information such as a road signal lamp is located, and the changed road identification information may be determined and saved to the corresponding data layer.
In one possible implementation, the road arc, road NODE, road obstacle point, road identification information, etc., which have changed as described above, may also be assigned specific attribute values, for example, attribute values identified as NODE _ ID, START _ NODE _ ID, and/or END _ NODE _ ID for road NODEs, attribute values identified as LINK _ ID for road arc, attribute values identified as NODE _ ID for road obstacle points, etc., may be assigned. The present disclosure does not limit the identification.
In a possible implementation manner, after at least one of the changed road arc segment, road node, road obstacle point and road identification information is acquired and a new attribute value is given, the geographic element database may be updated by using the road geographic element with the new attribute value, so as to obtain an updated geographic element database.
In one possible implementation, the target geographic element may include a waters geographic element. For the geographical elements of the water area, step S12 may include: verifying the water area identification of the water area geographic element to obtain a verification result; and under the condition that the verification result is that the verification is passed, updating the geographic element database according to the water area identification to obtain an updated geographic element database.
In one possible implementation, the water area identifier may be verified, for example, compared with a preset comparison table, to obtain a verification result. The preset comparison table can be a comparison table for marking the name or the identification of the water area, and the water area identification of the geographical elements of the water area can be compared with the name or the identification of the water area in the comparison table to obtain a verification result. For example, the connectivity of the water area can be used to determine whether the changed water area geographic element belongs to the water area geographic element in the geographic element database, and the water area name or the identification of the water area geographic element is determined by the relationship, and then compared with the comparison table to obtain the verification result. The verification result can indicate whether the water area name or the identification of the water area geographic element is consistent with the comparison table.
In a possible implementation manner, according to the verification result, the identifier of the changed water area geographic element is kept consistent with the identifier in the comparison table, and the geographic element database is updated, for example, the identifier of the changed water area geographic element in the geographic element database is updated, and the updated geographic element database is obtained.
In a possible implementation manner, the identification of the target geographic element that has changed may be corrected, for example, the target geographic element with repeated value, null value, and error value may be corrected, and the value may be assigned according to a preset identification code, for example, the identification of the geographic element in the county level area is coded by using 13 digits, the first 6 digits are county level partition codes, and the last 7 are element sequence codes. The identification of the geographic elements of the upgrading region adopts a code consisting of 7 digits, wherein the first 2 digits are the first two digits of a provincial code, and the last 5 digits are element sequence codes. Further, assignment can be performed on the partition codes of different areas. The present disclosure is not limited to a particular format of identification of the geographic element.
In one possible implementation, the start times of all the elements may also be updated, for example, the start time of the target geographic element that changes in the current update is updated, and the update times of other geographic elements are recorded, for example, the time when some geographic elements are updated in the past. An expiration time for the updated geographic element may also be determined.
In an example, for certain census geographic elements, the starting time of the geographic element may be updated to census time, e.g., an attribute value of the geographic element with respect to time is updated to census time, e.g., 20150630. Further, the start time of the updated target geographic element may be updated, for example, the start time of the new or changed target geographic element is XXXX0630, and the end time is null.
