The vector data model uses points, lines, and polygons to represent geographic features. It is commonly used for storing and analyzing discrete objects with well-defined boundaries.

Spatial analysis involves overlaying GIS layers to perform operations such as intersection, union, and buffer analysis. It helps identify patterns, relationships, and trends in geospatial data.

The join operation in GIS combines the attributes of two or more layers based on a common field or attribute. It allows you to enrich the data in one layer with information from another layer.

Vectorization is the process of converting raster data, which is composed of pixels, into vector data, which consists of points, lines, and polygons. This conversion allows for more precise representation and analysis of geographic features.

Interpolation is a GIS technique used to estimate values at unsampled locations by considering the values at nearby sampled locations. It helps create continuous surfaces from discrete data points.

Georeferencing is the process of assigning geographic coordinates to a map or image, allowing it to be accurately positioned and aligned with other geospatial data.

Buffering is a GIS operation that creates a new layer representing the area within a specified distance from a feature or set of features. It is commonly used for analysis and visualization purposes.

Generalization is the process of simplifying a complex GIS dataset by removing unnecessary detail. It helps improve the performance and readability of the data while preserving its essential characteristics.

Dissolve is a GIS operation that combines multiple features into a single feature based on a common attribute or characteristic. It is often used to simplify datasets and create thematic maps.

Thematic mapping is the process of creating a map that visually represents the distribution of a particular attribute or phenomenon. It helps communicate complex geospatial information in a clear and concise manner.

The intersect operation in GIS allows you to select features that intersect or fall within a specified area or boundary. It is commonly used to identify areas of overlap or proximity between different datasets.

The union operation in GIS combines two or more layers into a single layer, resulting in a new layer that contains all the features from the input layers. It is commonly used to merge datasets or create composite layers.

The intersect operation in GIS allows you to create a new layer representing the area that is common to two or more input layers. It is commonly used to identify areas of overlap between different datasets.

Clustering is the process of grouping similar features together based on their attributes or characteristics. It helps identify patterns and relationships within a dataset and can be used for data summarization and analysis.

The difference operation in GIS allows you to create a new layer representing the area that is outside of a specified area or boundary. It is commonly used to identify areas that are not covered by a particular dataset or to create exclusion zones.
