CRUD Operations on Vector Data
Vector data refers to data that represents geographic features as points, lines, and polygons. Performing CRUD operations (Create, Read, Update, Delete) on vector data is essential for managing and manipulating spatial information effectively. Below is a guide on how to carry out these operations:
Operation |
Description |
Create |
Adding new vector data to the existing dataset. This can involve drawing new points, lines, or polygons on a map or importing data from external sources. |
Read |
Viewing and accessing existing vector data. This can include querying specific features, displaying attribute information, and visualizing spatial relationships. |
Update |
Modifying existing vector data. This may involve editing attributes, changing geometries, or updating spatial relationships between features. |
Delete |
Removing unwanted vector data from the dataset. This can help in cleaning up the data, correcting errors, or managing data quality. |
