Technical Field

Background
In the geographic mapping, the DSM refers to a Digital Surface Model (Digital Elevation Model), and the DEM refers to a Digital Elevation Model (Digital Elevation Model), wherein the Digital Surface Model (DSM) refers to a ground Elevation Model including heights of ground buildings, bridges, trees, and the like, and the Digital Elevation Model (DEM) implements Digital simulation of ground terrain through limited terrain Elevation data, so compared with the DEM, the DEM only includes Elevation information of the terrain (including no buildings, bridges, trees, and the like, and the Elevation at the position corresponding to the DEM is the Elevation of the ground), and does not include other ground Surface information, and the DSM further includes elevations of other ground Surface information except the ground Surface on the basis of the DEM.
At present, a DSM model and a DEM model in the same area are stored in two different data files in the same data format, the data structures of the two data files are the same, only one data file is used for storing DSM data information, and the other data file is used for storing DEM data information, but the DSM model and the DEM model in the same area are in an area without houses, trees and the like, and the data of the DSM model and the DEM model in the same area are completely the same, so the generation work of the two sets of model data of the DSM and the DEM in the same area is repeated to a great extent, and particularly in a data edge connection and data quality inspection link, the repeatability performance is most obvious.
Therefore, the current storage method for the data of the DEM model and the DSM model in the same area has the following disadvantages: on one hand, in the production of the two sets of data, the repeated areas of the two sets of data are respectively checked, and in fact, in the repeated areas, one part of data has no problem, and the other part of data has no problem, so that the storage mode increases the workload; on the other hand, in some cases, the duplicate areas of the two sets of data need to be compared to ensure that the two sets of data are completely consistent, which obviously further increases the data production cost. In addition, storing two copies of data takes up more storage space, resulting in higher storage costs.

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.
Example 1:
a data storage method, please refer to fig. 1 to 3.
As shown in fig. 1, the data storage method establishes a DMM data table, where the DMM data table includes a row address and a column address, the row address represents an abscissa i of a mapping area, the column address represents an ordinate j of the mapping area, and a DMM value of a position where the row address is i and the column address is j in the DMM data table is dijE.g. d00The DMM value of a mapping point of the mapping region with abscissa 0 and ordinate 0 is represented.
The DMM value here is used to represent a corresponding value of DSM model data or DEM model data, and in this embodiment:
when the corresponding ground surface position of the surveying area is covered without obstacles, the DEM value e of the positionijAnd DSM value sijHere again, the DEM value eijDSM values s for corresponding values (digital elevation model values) in DEM model dataijFor corresponding values (digital surface model values) in DSM model data, in which case the DMM value d in the DMM data tableijDSM value s for that locationij+ identifier 1, in this embodiment, identifier 1 is number 0, and identifier 1 only plays a role of identification, and may be a space or contain no content. Of course, due to DSM value sijAnd DEM value eijThe same, therefore, the DMM value d in the DMM data table at this timeijOr the DEM value e for that positionij+ identifier 1.
The obstacles include buildings, vegetation, and the like covering the ground.
And when the corresponding ground surface position of the mapping area is covered by the obstacle, the DSM value s of the positionijDEM value e greater than this positionijAt this time, in the DMM data tableDMM value dijDSM value s for that locationij+ identifier 2, and sequentially recording DEM value e of corresponding position at the end of the ith row corresponding to the DMM data tableij. In other embodiments, if the DMM value d in the DMM data table is not presentijFor the DEM value e of the positionij+ identifier 2, the end of the ith row corresponding to the DMM table records the DSM value s of the corresponding location in sequenceij。
Thus, the DMM data table stores both DSM model data and DEM model data of the mapped area.
For example, referring to fig. 2 and fig. 3, data tables (a) and (B) in fig. 2 are schematic diagrams of storage of DSM (model development system) data and DEM (model development module) data in the prior art, respectively, and it can be seen that the DSM data and the DEM data are recorded by a single data table, which obviously causes storage of mapping data to occupy a large memory, and the two data need to perform operations such as comparison, edge connection, and the like in a production process, so that a workload of production data is large.
In fig. 3, the data stored in the data table (a) and the data table (b) represent the DSM model data and the DEM model data in fig. 2, respectively, the data table (3) represents the DMM data in the present embodiment, and the data table (3) stores both the DSM model data and the DEM model data in the data table (a) and the data table (b).
Specifically, the data beginning with "s" in the data table (c) represents that the DSM model data value and the DEM model data value at the position are the same, so the data beginning with "s" in the data table (c) is added with an identifier 1, and the identifier 1 indicates that the DSM model data value and the DEM model data value are the same; since the data at the beginning of "m" in the data table (c) represents that the DSM model data value and the DEM model data value at the position are different, the data at the beginning of "m" in the data table (c) is added with the identifier 2, and the identifier 2 indicates that the DSM model data value and the DEM model data value are different, and at the same time, the data at the end of the line corresponds to the DEM model data value at the position where the data at the beginning of "m" corresponding to the data at the end of the line is located in the mapping area.
The embodiment expresses the data storage method in the form of a data chart, and the data can also be stored in a computer readable storage medium after being encoded by various encoding methods such as ASCII code, CJK code, ISO code UTF code, GBK code and the like.
Example 2:
a data storage method for storing DSM model data and DEM model data of a mapping area in a computer-readable storage medium.
In the present embodiment, the computer-readable storage medium includes a storage unit having a grid pattern arrangement, and the storage unit stores therein the DMM data in the DMM table in embodiment 1, the DMM data being used to store simultaneously the DSM model data and the DEM model data of the mapped area.
In this embodiment, the memory cell includes a row address and a column address, the row address represents an abscissa i of the mapping region, and the column address represents an ordinate j of the mapping region; the DMM value of the position with the row address i and the column address j in the memory cell is dij。
When the corresponding ground surface position of the surveying area is covered without obstacles, the DEM value e of the positionijAnd DSM value sijSame, DEM value eijFor corresponding values in DEM model data, DSM values sijIs the corresponding value in DSM model data, at this time, the DMM value d in the storage unitijFor the DEM value e of the positionij+ identifier 1, identifier 1 being the number 0, identifier 1 starting with the DSM value s identifying the locationijWith DEM value eijThe same effect is achieved.
The obstacles include buildings, vegetation, and the like covering the ground.
When the corresponding ground surface position of the mapping area is covered by the obstacle, the DSM value s of the positionijDEM value e greater than this positionijAt this time, the DMM value d in the memory cellijFor the DEM value e of the positionij+ identifier 2, and sequentially recording DSM values s of corresponding positions at the end of the corresponding ith row of the storage unitij. Where identifier 2 is the number 1, identifier 2 serves as the DSM value s identifying the locationijAnd DEValue of M eijDifferent effects.
Example 3:
a data storage method for storing DSM model data and DEM model data of a mapping area in a computer-readable storage medium, which is different from embodiment 2 in that:
in the data storage method of this embodiment, when the corresponding surface location of the surveying area is covered without obstacles, the DMM value d in the storage unitijDSM value s for that locationij+ identifier 1; and when the corresponding surface position of the mapping area is covered by the obstacle, the DMM value d in the storage unitijDSM value s for that locationij+ identifier 2, and sequentially storing DEM values e of corresponding positions at the end of the corresponding ith row of the storage unitij。
Example 4:
a data storage device, which may be a computer, a server, or a tablet computer-enabled electronic device capable of creating a data table, is capable of creating a DMM data table according to the data storage method in embodiment 1, and storing DMM data in the data storage device.
Example 5:
a computer-readable storage medium in which data stored according to the data storage method in embodiment 5 is stored. The storage medium herein includes: various media capable of storing program codes, such as a U disk, a removable hard disk, a Read Only Memory (ROM), a Random Access Memory (RAM), a magnetic disk, or an optical disk.
Example 6:
a data reading method, please refer to fig. 3.
The data reading method is used for reading the computer-readable storage medium in the embodiment 5, and comprises the following steps:
when the DMM data in the computer-readable storage medium is used as DSM model data, the DMM data of the storage unit with the abscissa of i and the ordinate of j in the computer-readable storage medium directly takes the DSM value sij。
For example, as shown in FIG. 3, the meterThe computer readable storage medium stores DMM data of a certain mapping area indicated by a data table (c), wherein the data table (a) represents DSM model data of the mapping area and can be read through the DMM data, and data in a main table (not containing data at the rear side of a 9 th column) of the data table (c) for recording the DMM data is directly a DSM value s at a corresponding positionijThus, the direct reading is the DSM value sij。
In the process of reading DSM model data, j values (j is 9 in the embodiment) are read by data according to lines, when j data are read, the line number is added with 1, the next line is read until i lines (i is 9 in the embodiment) are read, and the reading is finished.
When the DMM data in the computer-readable storage medium is used as DEM model data, for the DMM data of the storage unit in the computer-readable storage medium whose abscissa is i and ordinate is j position:
when reading identifier 1, DMM data directly takes DSM value sij(ii) a Here, although DSM values s are described in the main table of DMM dataijBut since identifier 1 represents the DSM value s of the locationijWith DEM value eijSame, therefore, DEM value eijCan directly take DSM value sij。
When the identifier is read as the identifier 2, the DMM data directly takes the DEM value e stored at the position corresponding to the tail end of the lineij。
Here, since the main table of DMM data records DSM value sijAnd identifier 2 represents the DSM value s for that locationijWith DEM value eijDifferent, therefore, the DEM value eijNot directly taking the value s of DSMijBut takes the value as the DEM value e of the corresponding position at the rear side of the lineij. For example, for the data m22 in the data table (c), it is actually equal to s22+ identifier 2 in the data table (a), but since identifier 2 is read, data s22 in the representative data table (a) is different from data e22 in the data table (b), so when reading the DEM model data, e22 cannot be replaced by data m22 in the data table (c), but data e22 on the rear side of the main table of the data table (c) is directly read.
In the process of reading the DEM model data, the data reads n values (representing the number of data in the longest row, where n is 12 in this embodiment) according to rows, when n data is read, the number of rows is increased by 1, and the next row is read until m rows are read (m is 9 in this embodiment), and the reading is finished.
Therefore, the data storage method can effectively reduce the data storage cost, and the existing storage mode basically occupies twice of the memory; in addition, the data storage method saves the comparison work of DEM data and DSM data, and reduces the data edge connecting workload, thereby reducing the production cost of the mapping data and improving the production efficiency and quality of the mapping data.
It should be noted that, in this document, the terms "comprises," "comprising," or any other variation thereof, are intended to cover a non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements does not include only those elements but may include other elements not expressly listed or inherent to such process, method, article, or apparatus.
Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
