range description + scale + tabular data title + '(' + phase + ')';
finally, rendering the i (i ═ 1,2,3, …) pieces of spatial data obtained after splitting to respectively generate i (i ═ 1,2,3, …) layer files, wherein if the i (i ═ 1,2,3, …) pieces of spatial data only express a spatial range (namely only range description) and do not have thematic information, the file names of the i (i ═ 1,2,3, …) layer files are the same as the names of the i (i ═ 1,2,3, …) pieces of spatial data; if i (i ═ 1,2,3, …) pieces of spatial data have n (n ═ 1,2,3, …) thematic attribute fields, each thematic attribute needs to be rendered, i (i ═ 1,2,3, …) pieces of spatial data are rendered according to n (n ═ 1,2,3, …) thematic attributes respectively, the i (i ═ 1,2,3, …) pieces of spatial data generate n (n ═ 1,2,3, …) piece of layer files respectively, and the encoding rule of the generated layer files is as follows:
data encoding + "_" + subject field encoding;
the naming rule is:
data name + "_" + title field name.
Preferably, if the phase of the spatial data is a time period (e.g., 1990 @; 2010), the latest time may be adopted as the phase of the spatial data (e.g., 2010).
One preferred example of tabular data processing is as follows:
coding sample example: BSUF1160392000T2110801042_1996_ CZMD
Wherein B represents nationwide; s is a scale separator; u represents 1:400 ten thousand scale bars; f is a space data separator; 11603920000 is element class code of spatial data; t is a table data separator; 2110801042 is element class code of table data; 1996 for time; CZMD is the topic field (i.e., bearing density).
Sample naming: population bearing Density of provinces across the country (1996)
The normalized coding is to perform normalized coding on the generated spatial data, and includes range coding (for example, global, national, foreign region, national region, or city), scale coding, and element class coding, and is specifically specified as follows:
i) range coding
The range code consists of 1-bit capital letters and can be divided as follows:
| range of | Global system | Nationwide | Foreign region | National area | City |
| Code | A | B | C | D | E |
Preferably, the range coding division may be wide, but needs to be described specifically when the data is named, for example, the kyuji area belongs to a national region, the range is coded as D, but the range description in the data naming needs to be described as the kyuji area.
ii) scale encoding
According to the national basic scale topographic map framing and numbering, the method can be divided into the following steps:
| scale bar | 1:100 ten thousand | 1:50 ten thousand | 1:25 ten thousand | 1:10 ten thousand | 1:5 ten thousand | 1:2.5 ten thousand | 1:1 ten thousand | 1:5 thousand |
| Code | A | B | C | D | E | F | G | H |
Preferably, the following custom partitions may also be included:
| scale bar | 1:70 ten thousand | 1:250 ten thousand | 1:500 ten thousand | 1:600 ten thousand | 1:400 ten thousand |
| Code | Q | R | S | T | U |
| Scale bar | 1:450 ten thousand | 1:1000 ten thousand | 1:1200 ten thousand | 1:1400 million | 1:3300 ten thousand |
| Code | V | W | X | Y | Z |
| Resolution ratio | 1km | 100M | |||
| Code | K | M |
iii) element class encoding
The element class codes can be codes composed of 10 digits, the codes can be obtained according to project standard 'information base element class coding scheme', and in practical application, the codes can be obtained from comprehensive information base data codes. For example:
data sample: ZZG01030 the element class code of 01030R2420181101 is 2420181101;
data sample: ZZG01003 where the element class code for 01003F2140200000A is 2140200000;
data sample: ZZG01003T2140200000 has an element class code of 2140200000.
