Quels sont les trois fichiers obligatoires que contient le shapefile ?<end_of_turn>
<start_of_turn>model
A shapefile, which is a common geospatial vector data format, typically consists of three mandatory files:

1. .shp (Shapefile): This file contains the geometric data, including points, lines, and polygons, that represent the spatial features of the shapefile. It stores the coordinates and attribute information associated with each feature.
2. .shx (Shapefile Index): This index file is used to optimize spatial queries and access the shapefile's features more efficiently. It contains a pointer to the location of each feature's geometry in the .shp file.
3. .dbf (Attribute Table): This file stores the attribute data associated with the spatial features in the shapefile. It is a dBASE format file and includes tables with records and fields, where each field represents a different attribute or characteristic of the features.

These three files (.shp, .shx, and .dbf) work together to provide the spatial and attribute information necessary for working with shapefile data. While the .shp and .dbf files are essential for storing the geometry and attribute data, respectively, the .shx file enhances the shapefile's performance by providing an index for faster access to the features.<end_of_turn><eos>
