Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Referring to fig. 1, a method for rearranging serial numbers and transmitting post numbers of road sections of a road network data includes the following steps:
step 1: preparing data, namely warehousing and primarily processing the data to be subjected to the sequence number rearrangement of the road section;
for convenience of processing, the road network data in the Shapefile format is imported into a database, such as Oracle or SQL Server, through ArcSDE, wherein the attribute data is stored in corresponding attribute fields in the database, the spatial data is stored in a SHAPE spatial field, for convenience of calculation, the SHAPE type is set as a Geometry type, and the spatial coordinate system selects a geographic coordinate system, such as: WGS84 coordinate system.
Step 2: problem checking, which comprises checking and positioning eight types of problems affecting the rearrangement of the serial numbers of the road sections; the eight types of problems are respectively: there are branch intersections, the route is a circular shape, there is no connection in the route, there is a reverse direction in the route, there is no designation or designation of a plurality of first road segments in the route, the designated first road segments in the route are non-first road segments, road segment linear repetition and null patterns, wherein eight types of problems are defined as follows:
1) and (3) blank pattern: data whose spatial information is empty exists in the route.
Under the appointed projection band, reading the space information of the road section, if the space information can not be read normally, the road section is an empty graph. The types of empty patterns are mainly three: the space information is not filled in, the filling of the space information is not standard so that the space information cannot be analyzed normally, and the longitude and latitude of the road section are not matched with the current projection belt so that the road section cannot be read. The reasons for generating the blank pattern mainly include non-standard in the data acquisition process, misoperation in the data editing process and other events causing data damage. The existence of empty graphics can affect the integrity of the route and also result in the inability to map and edit spatial information for the road segments.
2) The route is annular: all road sections in the route are sequentially connected end to end, and the starting point and the end point of the route are overlapped.
The method for detecting the circular route comprises the steps of firstly obtaining the starting and stopping points of all road sections in the route, and if each point is close to the starting and stopping points of some other road section, the route is circular.
3) Branching intersections exist in the route: three or more road sections in the same route intersect at the same position, namely, a fork exists in the route.
The method for detecting the existence of the branched intersection in the route comprises the steps of obtaining the starting points and the ending points of all road segments in the route, placing the starting points and the ending points in a two-dimensional grid with a fixed size according to the horizontal and vertical coordinates of the starting points and the ending points, and judging that the branched intersection exists if more than three road segment starting points exist in a certain grid.
4) There are unjoins in the route: the situation that the end points of two adjacent road sections are not connected exists in the same route
The method for detecting whether the routes are not connected comprises the steps of calculating the distances between the start points and the stop points of all road sections in the routes, and judging whether the distances between the start points and the stop points of other road sections exceed a certain threshold value to be not connected.
5) There is a reversal in the route: and in the same route, the direction of the first road section is taken as the correct direction, and if the directions of other road sections are not consistent with the direction of the first road section, the reverse direction exists in the route.
The method for detecting the existence of the reverse direction in the route takes the direction of a first section of road in the route as the direction of the route, the spatial distance between the starting point and the ending point of the last section of road in the route is calculated, and the condition that the distance between the starting point of the section of road and the ending point of the last section of road is too large or the distance between the starting point of the section of road and the ending point of the last section of road is smaller than the distance between the starting point of the section of road and the ending point of the last section of road on the contrary is judged that the reverse direction exists in the route.
6) No or multiple first segments are specified in the route: a first road section is not appointed in the route or more than two road sections are appointed as the first road section;
the method for detecting the unspecified or specified first road sections in the route is to search the specified attributes of all road sections of the whole route, and if the unspecified or specified first road sections are in the attribute field, the route is judged to be unspecified or specified first road sections.
7) The first segment specified in the route is a non-first segment: the first segment of the route is not, in spatial position, the first segment of the route.
The main basis of the error type detection algorithm is that under normal conditions, except for the annular route, the distances between the starting point of the first road section and the starting points of other road sections are far, and if the distances are not consistent, the first road section in the route can be determined to be a non-first road section.
8) Road section linear repetition: in the same route, the start and stop points of two road sections are superposed with each other.
The road section linear repetitive detection algorithm compares every two road sections of the route, and for A, B two road sections, if the distance of the starting point and the distance of the end point are both similar, or the starting point of the road section A is similar to the end point of the road section B, and the end point of the road section A is also similar to the starting point of the road section B, the road section linear repetitive detection algorithm can judge that the road section linear repetitive detection algorithm is the road section linear repetitive.
And step 3: modifying the problems, namely modifying the eight types of checked problems influencing the rearrangement of the serial numbers of the road sections; and correspondingly modifying the checked related problems to enable the related problems to meet the condition of pile number transmission, and modifying partial problems (including that the route is annular and branch intersections exist in the route) after verification is carried out by combining the remote sensing image. The embodiment provides the detection result to the user in the form of a detection report, is assisted by a map positioning function, and is verified by combining a high-resolution remote sensing image, so that the problem route is confirmed and modified;
and (4) after the problem modification is completed, repeating the steps 2 and 3 until no problem route exists, and executing the step 4.
And 4, step 4: the method comprises the steps of rearranging road section serial numbers, and then correspondingly adjusting information related to the road section serial numbers, such as accessory facilities, repeated route codes and the like; in this step, after the modification in step 3, step 2 needs to be performed again to ensure that all eight types of problems affecting the rearrangement of the segment serial numbers have been modified. Because the serial number of the road section is a component of the road section code in the serial number of the road system, the rule of the road section code is as follows: route coding + administrative division code + road section serial number, road section coding also changes after the road section serial number is rearranged, the road section coding belongs to the unique identifier of the road section, and the connection relation between different layers in the road basic data layer is the used road section coding and needs to be changed together. Mainly relates to corresponding section codes in the highway affiliated facilities; repeated section codes in the repeated section. In order to ensure that records can be checked in the process of rearranging the serial numbers of the road sections, firstly, a road section serial number adjustment corresponding table is generated, the adjusted serial numbers of the road sections and the adjusted serial numbers are recorded in a database, and then, the related information after the rearrangement of the serial numbers of the road sections is adjusted in batches.
1) Generating road section serial number adjustment corresponding table
In order to record the whole process of adjusting the serial numbers of the road segments in the past, writing a road segment serial number adjustment table into a corresponding database, wherein the structure of the database table is shown in fig. 2, and the CROWID is the unique identifier of the database of the road segment; LDBM is road section code; LXBM is route coding; LDXLH is a road section serial number; NEW _ LDXLH is the rearranged link sequence number.
2) Segment sequence rearrangement
And adjusting the corresponding table according to the generated road section serial number, and replacing the road section serial number in the road section table with a new road section serial number. In specific implementation, in order to avoid interference of the situation that the road segment codes are repeated, the unique identifier CROWID of the road segment is used for batch adjustment of the serial number of the road segment.
3) Batch adjustment of related information after rearrangement of road section serial numbers
After the road section serial number is adjusted, information related to the road section serial number needs to be updated in batch, and the information mainly relates to road section codes corresponding to road infrastructure and repeated road section codes in repeated road sections in a road section code table. In specific implementation, for convenience of implementation, programming is performed based on a storage process, and old road segment serial numbers are adjusted to new road segment serial numbers in batches.
And 5: and (3) transmitting the pile numbers of the routes, which comprises updating the pile numbers of the starting and ending points of the road sections, updating the pile numbers of the attached facilities in the routes and updating the pile numbers of the starting and ending points of the repeated road sections in the repeated road sections. For national roads, because the national roads generally span a plurality of provinces, entrance and exit stake numbers between the provinces are negotiated and determined, and the consistency between the exit and entrance stake numbers of routes between the provinces and the negotiation values needs to be ensured in the stake number transmission process. Pile number transmission is carried out on the basis of the adjusted road section serial number, and the pile number is transmitted according to the actual mileage of the route track on the premise of knowing the pile number of the starting point of each route according to the relevant regulations of a transportation department or a transportation hall of each province.
1) Path segment length computation
For processing convenience, after the road network data is put in storage through the ArcSDE, a WGS84 geographic coordinate system is generally selected, and the OGC method STLength () supported by the SQL Server on the geometric graph instance is used to calculate the road mileage.
2) Pile number transmission
The pile number transmission means that the end pile number of the road section is formed by adding the road section length calculated in the previous step according to the starting pile number of each route, and the specific calculation formula is as follows:
wherein, P0For the starting point stake number of the route, for the national road, as it generally spans a plurality of provinces, the exit stake numbers between the provinces have been negotiated, P0The road needs to be determined according to a 'national highway network mileage post number transmission scheme' issued by the department of transportation, and other roads (provincial road, county road, rural road, village road and special road) need to be transmitted according to the actual regulations of each province because the roads are limited to a provincial scope, and general P is0Equal to 0. PS (polystyrene) with high sensitivityiFor the start stake number, PE, of the ith road section in the routeiIs the terminal pile number of the ith road section.
3) Updating attributes associated with stake numbers
After the pile number is updated, the attribute information related to the pile number needs to be updated, including updating the start and end point pile number of the road section, updating the pile number of the attached facility in the route, and updating the start and end point pile number of the repeated road section in the repeated road section.
The method provided by the invention is explained by taking the road basic data of a certain province as an example: firstly, preparing data, namely importing the data into an SQL Server database through ArcSDE, and endowing the data with a WGS84 coordinate system; then, carrying out problem detection on the road segment serial numbers, finding out eight kinds of problems influencing the rearrangement of the road segment serial numbers, and verifying and modifying data by using all the problems; secondly, rearranging the serial numbers of the road sections, firstly generating a road section serial number adjustment corresponding table to ensure that the record of the road section serial number rearrangement operation can be checked, recording the road section serial numbers which are adjusted in the past and the adjusted serial numbers into a database as shown in figure 2, and then carrying out batch adjustment on relevant information after the rearrangement of the road section serial numbers, wherein the relevant information comprises road section codes corresponding to road infrastructure and repeated road section codes in repeated road sections in a road section code table; finally, pile numbers are transmitted on the basis of the adjusted road section serial numbers, and according to relevant regulations of a transportation department or a transportation hall of each province, as shown in fig. 3, the pile numbers are transmitted according to actual mileage of a route track on the premise that the pile numbers of the starting points of each route are known.
In summary, the method for rearranging serial numbers and transmitting stake numbers of road network data road segments provided by the invention firstly detects eight types of problems affecting the rearrangement of the serial numbers of the road segments, provides the detection result for users in the form of detection report and provides the function of direct map positioning, facilitates the users to confirm and modify the problems, then rearranges the serial numbers of the road segments after the eight types of problems are confirmed, correspondingly and automatically modifies the relevant map layers related to the serial numbers of the road segments in the rearranging process, finally transmits the stake numbers based on the road segments after the serial numbers of the road segments are rearranged, correspondingly updates the stake numbers related to the accessory facilities and the repeated road segments in the stake number transmitting process, uses the geographic information space technology, adjusts the serial numbers and the stake numbers of the road network road segments according to the requirements of departments and provinces after the road network is adjusted, and can quickly position the problems to be solved by the rearrangement of the serial numbers of the road segments, the efficiency of road network updating post road segment sequence number rearrangement and stake number adjustment is greatly improved, and higher precision is guaranteed.
