Description

Encoder, encoding method and equipment for place name and identity number based on space-time service

technical field

The invention relates to a place name identity number (place name ID) encoder, encoding method and equipment based on space-time services, and belongs to the fields of geographic space information organization and geographic information system.

Background technique

Currently, there are two types of coding methods for place name ID numbers. One is the encoding method that takes into account the semantic information of geographic entities. This type of coding method contains the classification information of geographical objects, but this type of coding method usually uses administrative divisions to describe spatial information, and lacks the ability to describe precise locations. Moreover, geographical names involve multiple business management departments according to their types, and each department independently manages the code according to the needs of the department. Therefore, a common problem arises: different codes exist for the same geographical entity object in different systems. The other is the spatial position encoding method, such as the global discrete grid encoding model. This type of code has a strong ability to describe spatial locations, and the location information of geographic entities described by it can be accurate to the centimeter level. However, there is a lack of semantic information of geographic objects, and a clear description of the category to which geographic objects belong.

The traditional place-name ID coding method cannot take into account the integration of place-name ID semantics and spatial location information, making it difficult to update, associate, exchange and share place-name information.

See Figures 7 and 11. The calculation method is as follows:

X＝(Xmax+Xmin)/2 (1)

Y＝(Ymax+Ymin)/2 (2)

When X is in east longitude:

GX＝(rounded)[X/360]*65536 (3)

When X is in west longitude:

GX＝(rounding)[(X+180)/360]*65536 (4)

When Y is at north latitude:

GY＝(rounded)[(90-Y)/180]*32768 (5)

When Y is at south latitude:

GY＝(rounded)[(90+Y)/180]*32768 (6)

Get GX=

bx15bx14bx13bx12bx11bx10bx9bx8bx7bx6bx5bx4bx3bx2bx1bx0;

Get GY=

Step 7: Life cycle code calculation process

Read the date data of the date generation module, obtain and determine the seventh segment life cycle code GNC7 of the place name ID code, see Figure 8. The life cycle code represents the generation or identification date of the place name, and represents the time information when the life cycle management of the place name starts. According to the standard "GB/T 7408-2005 Data Element and Interchange Format Information Exchange Date and Time Representation", the life cycle code adopts CCYYMMDD (CCYY: year, MM: month, DD: day) 8-digit decimal number format, see Figure 8 , 11.

For the geographical name life cycle code of the natural geographic entity, the record date of the geographical names shall prevail. The value of century, year, month, and day that cannot be determined and has been generated in history is 00; the life cycle code of place names of artificial production and construction and social management is subject to the date approved, completed or agreed by the administrative unit.

The date generation module generates date data synchronously according to the encoder system. Reading the date data of the date generation module means that the current date data is valid, and then the system date is automatically collected. For the current date of the historical place names and geographic entities, the current date is invalid, and the required date is manually input. data.

Step 8: Sequential Counting Code Calculation Process

Read the last cumulative sequential coding data of the counting module, and add 1 (according to the continent and international public domain codes of place names, country and region name codes, administrative division codes, administrative division codes below the county level) on the basis of the last cumulative sequential coding data. Under the condition that the division code, place name geographic attribute category code, and spatial grid code are all the same, add 1 to the cumulative value of the counter of the counting library module on the same day, so that the sequence counting code does not repeat), and generate the 8th segment of the place name ID code for sequential counting Code GNC8, see Figures 9 and 11.

Step 9: Check code calculation process

Read the verification rule information data of the verification library module, for continent or international public domain codes, country and region name codes, administrative division codes, administrative division codes below the county level, geographical attribute codes of place names, spatial grid codes, life cycle Code, sequence counting code 8-segment code, using "GB/T 23732 China Standard Text Coding" check character system mod16-3 method to generate check code GNC9. By using the check code, it can be found that the identity number of the place name generates a code error during the transmission process. See Figures 10 and 11, Example 1.

Step 10: Place name identity code encoding output

On the basis of the generation of the above codes, according to Geo_Name_Code=GNC1: GNC2: GNC3: GNC4: GNC5: GNC6: GNC7: GNC8: GNC9 (where ":" represents the serial relationship between the segmented codes), the calculation code module merges the above 9 Segment code value, and output place name identity number Geo_Name_Code data.

The final code structure of place name ID is composed of continent and international public domain code (1 digit), country and region name code (3 digits), administrative division code (6 digits), administrative division code below county level (3 digits), place name geographic Attribute category code (6 digits), space grid code (8 digits), life cycle code (8 digits), sequence count code (4 digits), check code (1 digit) consists of 9 segments. The place name ID code has a total of 40 digits, as shown in Figure 11.

Place name ID is called domestic place name ID when it is used in China, and the coding structure can be simplified as administrative division code (6 digits), administrative division code below county level (3 digits), place name geographical attribute category code (6 digits), spatial grid code (8 digits), life cycle code (8 digits), sequence count code (4 digits), check code (1 digit) consists of 7 segments, and the ID code of domestic place names totals 36 digits.
