In this embodiment, the entry of the data of the river and lake directory only relates to the actual administrative division data and the longitude and latitude data of the river and lake, where the actual administrative division data includes four levels, namely, the city, the county, the town and the village where the river and lake are located, and in order to facilitate the judgment and the correction of the administrative division of the river and lake directory information, the format of the data is defined when the data is entered, for example, when the administrative division of a river and lake is entered as A1 city, A2 county, A3 town A4 village, the entry format of the actual administrative division data a of the river and lake by the entry system is predefined as A1A2A3A4, and A1-A4 are respectively related information under the division fields of each administrative division, where the data entry of A1-A4 may be the expression of the pinyin, the initials, the numerical codes, or any other judged river and lake information of the administrative division.
When the data of the river and lake directory is imported by one key, the system identifies the recorded data and the predefined format of the system, and records the actual administrative division information A1-A4 of the river and lake directory into corresponding fields to obtain the actual administrative division data A of the river and lake. In order to judge the actual administrative division data A of the river and the lake and pre-registered administrative division data B pre-registered by the homeland department, the actual longitude and latitude data of the river and the lake are recorded, wherein a mapping relation is established between the actual administrative division data A of the river and the lake and the longitude and latitude data, and the pre-registered division data B provided by the homeland department is obtained by taking the longitude and latitude data as an intermediate variable. The latitude and longitude values can be applied to a plurality of different coordinate systems, such as Beijing 54, Xian 80 and WGS-84 coordinate systems, and the recording format of the latitude and longitude values can be set according to the different coordinate systems. Taking a WGS-84 coordinate system as an example, positioning longitude and latitude values into a WGS1984 coordinate system, overlapping the longitude and latitude values with city, county, town and village four-level administrative divisions provided by the national and local departments for spatial analysis, and identifying pre-registered administrative division data B of the river and lake object in a map.
In order to facilitate the determination of the actual administrative district data a and the pre-registered administrative district data B, the pre-registered administrative district data B may be stored in advance in the predetermined field format, that is, the format of the pre-registered administrative district data B is B1B2B3B4, and the pre-registered administrative district data B is stored in the city, county, town, and village four-level administrative districts, when the actual administrative district data a and the pre-registered district data B are determined, the marks on the respective fields are compared, that is, whether the data in the fields of a1 and B1, a2 and B2, A3 and B3, a4 and B4 are the same or not is determined, and the comparison and determination are performed according to whether the data comparison is consistent or not, and the determination is fed back as the result of whether the entry data is standard or not.
Example 2
As shown in fig. 2, the present embodiment provides a method for determining names and accurate positions of rivers and lakes, which is used for matching and determining actual names and accurate positions, such as longitude and latitude, of the river and lake directory objects displayed on a map, with names and longitude and latitude of the river and lake directory objects in the filling data, so as to ensure that the entry of the river and lake directory data is accurate, and the method includes:
step S201: data entry, wherein the data comprises actual names and actual longitude and latitude data of river and lake objects;
step S202: when the actual name and the actual longitude and latitude data are recorded, establishing a mapping relation between the actual name and the actual longitude and latitude data;
step S203: searching a pre-filled name in a river plotting layer according to the actual name, and if the pre-filled name consistent with the actual name is searched in the river plotting layer, executing a step S204; if the pre-filled name consistent with the actual name is not retrieved from the river plotting layer, executing step S205;
step S204: if the pre-filled longitude and latitude data of the pre-filled name in the river plotting layer is within the preset range of the actual longitude and latitude data, executing step S206;
step S205: positioning the actual longitude and latitude data position in the river plotting layer, identifying the pre-filled name in the preset range of the position, and executing step S206 if the actual name is consistent with the pre-filled name; if the actual name is not consistent with the name of the pre-filled report, go to step S207;
step S206: judging that the pointing position of the recorded river and lake object is consistent with the actual position, and feeding back the actual name of the river and lake and the actual longitude and latitude data as a standard recording judgment result;
step S207: and judging that the pointing position of the recorded river and lake object is inconsistent with the actual position, and feeding back the actual name of the river and lake and the pre-filled name of the river and lake as a non-standard recording judgment result.
In this embodiment, the entry of the river and lake directory data only relates to the actual name and the actual longitude and latitude data of the river and lake directory, wherein the entry of the river and lake directory may be the expression of the pinyin, the initial of the pinyin, and/or the digital code mixture of the name, or any other one of the other expressions for judging the name of the river and lake.
When the data of the river and lake directory is imported in one key, in order to judge the actual name C of the river and lake and the prefilled name D in the river flow standard drawing layer, the data also comprises the actual longitude and latitude data of the river and lake, wherein the mapping relation is established between the actual name C of the river and lake and the actual longitude and latitude data.
The pre-registration format of the pre-filled name D is the same as the recording format of the actual name C of the river or lake, when the actual name C of the river or lake and the pre-filled name D in the river flow mark drawing layer are searched, the graphic and character searching algorithm is used for searching in the drawing layer, the pre-filled name D of the river or lake in the drawing layer is searched, the pre-filled name D of the river or lake is consistent with the actual name C of the river or lake, and when the pre-filled name D is consistent with the actual name C of the river or lake, whether the pre-filled name D and the actual name C of the river or lake are in the same position needs to be judged. And obtaining pre-filled longitude and latitude data in the standard drawing layer with the pre-filled name D by taking the actual longitude and latitude data as an intermediate variable for comparison, and judging whether the actual longitude and latitude data and the pre-filled name D are really the same river and lake information.
Because each section of river and lake occupies a certain range of area in the river plotting layer, when the pre-filled longitude and latitude data and the actual longitude and latitude data are judged, a range is preset, the preset range is determined according to the length and the area of a specific river and lake, for example, the preset range takes the pre-filled longitude and latitude data center as the center of a circle and the maximum edge of the river or lake as the range of radius stroke, and when partial numerical range of the actual longitude and latitude data falls into the preset range, the pointed position of the recorded river and lake object can be judged to be consistent with the actual position.
As shown in fig. 3, some of the river and lake pre-filled names D are difficult to be identified in the river map drawing layer, and taking the river mark 11 in fig. 3 as an example, the pre-filled name D is not displayed side by side in the actual river plot due to the meandering direction of the river, but is displayed following the shape of the river, so that the computer cannot identify whether the pre-filled name D is consistent with the actual name C. Therefore, the actual longitude and latitude data center position corresponding to the actual name C, such as the center position of the river mark 11, is located in the river plotting layer, and the pre-filled name is recognized in the predetermined range a of the position, the predetermined range a is determined according to the length of the specific river, the pre-filled name recognition of the river is performed by taking the longitude and latitude data center position as the center and the predetermined range as the radius, in the circular range, if the character combination identical to the actual name C, such as the character combination, appears at the position of the river mark 10, the river with the pre-filled name D in the range is recognized, and the river pre-filled name D is consistent with the actual name C, so that the judgment result is fed back. And if the corresponding character combination cannot be searched in the preset range, judging that the pointing position of the recorded river and lake object is inconsistent with the actual position, and feeding back the actual name of the river and lake and the name of the river and lake pre-filling report as a judgment result.
Further, in step S204, if the pre-reported longitude and latitude data is not within the predetermined range of the actual longitude and latitude data, step S208 is executed;
step S208: and judging that the pointing position of the recorded river and lake object is inconsistent with the actual position, feeding back the actual name of the river and lake and the pre-filled name of the river and lake, and taking the actual longitude and latitude data as a non-standard recording judgment result.
If the pre-filled name consistent with the actual name is searched in the river plotting layer, but the pre-filled longitude and latitude data are not in the preset range of the actual longitude and latitude data, it is proved that rivers with the same name are owned at two places with different longitudes and latitudes in the river plotting layer, river and lake data with the same name are not recorded in the plotting layer, or the actual river and lake data recorded in the map layer are inconsistent with the pre-filled longitude and latitude data, the actual longitude and latitude data and the pre-filled longitude and latitude data of the river and lake name are fed back as a judgment result, and workers are prompted to correct the river and lake data.
In addition, the entry of the river and lake directory only has consistent names in general, and in practical situations, because of history and regional naming reasons, the name of the same river and lake or a plurality of different names, a mapping subset under each river and lake name is also established when data is pre-filled, the mapping subset records different names under the same river and lake name, including homophonic agreement and special names, when a computer system searches the actual name on the river plotting layer, in addition to identifying the river and lake name consistent with the actual name, the computer system also identifies according to other names in each pre-recorded mapping subset of the river and lake name, so that the integrity of the entry information is ensured, and when the system feeds back the actual name and the corresponding names of the mapping subsets, the standard entry of the river and lake names is ensured.
Example 3
The present embodiment provides a method for judging null value, non-numeric value, and data normalization of river and lake data, which is used for performing single inspection such as null value, non-numeric value, and data normalization on the format and content requirements of each attribute field of the entered data, so as to ensure accurate entry of river and lake directory data, and the method includes:
step S301: detecting null values of all fields, judging whether the input data are abnormal or not; and/or
Step S302: detecting a non-numerical value for the numerical range field, and judging whether the input data is abnormal or not; and/or
Step S303: judging the detection symbol of each field, and judging whether the input data is abnormal or not;
step S304: and feeding back the abnormal condition as a judgment result according to the null value judgment, the non-numerical value judgment and/or the symbol judgment.
In this embodiment, the null value is checked and judged to determine whether the entered information is complete, the cell to be filled is ensured not to be null by the null value judgment, and if the null value of a certain field n, namely the length of the river reach, is judged to be 0, that is, the cell is null, so as to determine that the length data of the river reach in the river and lake information is null, and the result of the judgment that the length information data of the river reach in which the river is located is missing is fed back to the staff and the river and lake data is corrected. And the non-numerical judgment prevents the input of numerical information from being wrong, and provides accurate information for the numerical analysis of rivers and lakes in the region. And the symbol judgment is based on format input, and whether the corresponding river information is input correctly is judged by examining whether brackets, units and the like are missing in the filled format.
