"Is Display map database just for displaying maps?"
"I don't understand how information such as building names, heights, and addresses are related"
Have you ever faced such questions or challenges when trying to use MapFan DB data?
In fact, MapFan DB's building data includes a "building ID" that serves as a key for linking to other related data.
This article explains how building IDs work and which data stores building IDs.
By understanding building IDs, you will be able to utilize Display map database more effectively.
💡 This article is recommended for:
・ Those who want to combine and utilize multiple data sets
・ Those who want to handle building-related information in an integrated manner
・ Those who want to know how to use building IDs
Building Polygons and Building IDs
What are Building Polygons?
Building polygons are data that represent the shapes of buildings such as schools, factories, hospitals, and private residences as areas (polygons).
Building polygons serve as the reference data for linking with other building-related data, such as Building height data and Building Routing Point data.
What are Building IDs?
Building IDs are identification information that is used to specify a building polygon.
Simply put, it's an identification number for distinguishing "this building."
This is assigned as an ID for data integration and is a separate ID from the "Object ID," which is unique to each object.
Use Cases with Building IDs
Building-related data stores building IDs as a common key.
This common identification number can be used to link different data sets together.
The following are some typical use cases:
Case 1: Referencing addresses from Building polygon data
Data to combine:
- Building polygon
- Address point databases
Expected flow:
Case 2: Referencing building entrance locations from addresses
Data to combine:
- Address point databases
- Building Routing Point
Expected flow:
Summary
The key points for integrating data using building IDs:
✅ Building ID is identification information for specifying buildings
✅ Building ID is different from Object ID
✅ By using building IDs, building polygons can be linked with related information such as addresses
✅ By combining data, practical functions such as address search and accurate navigation can be realized
