Resampling is the process of interpolating new pixel values while transforming raster data, often due to changes in resolution or coordinate transformation.

Reclassification involves altering the pixel values of a raster dataset based on a set of criteria, typically to simplify or tailor the data for specific analysis.

Radiometric correction is performed to correct a raster image for sensor irregularities and atmospheric conditions, improving the data accuracy.

Normalized Difference Vegetation Index (NDVI) calculation is used to measure vegetation health by comparing the difference between near-infrared and visible red light reflected by plants.

Mosaicking is the process of spatially combining multiple raster datasets to create a continuous image, useful for creating large-area maps.

Filtering applies a kernel or window of coefficients over raster data to enhance features or reduce noise, often used in image processing.

Subsetting extracts a smaller area or selection from a larger raster dataset, often for reducing the dataset size or focusing on an area of interest.

Contrast stretching enhances the dynamic range of raster image pixel values, often to improve visualization of features in imagery data.

Density slicing segments a continuous raster’s pixel values into discrete ranges to facilitate data visualization and interpretation.

Pan-sharpening combines higher-resolution panchromatic data with lower-resolution multispectral data to produce an image with the best qualities of both.

Zonal statistics calculates summary statistics (e.g., mean, sum, max, min) for raster data within specified zones, often used in habitat and land use analysis.

Spatial interpolation predicts unknown values across a surface based on known data points, used in creating continuous raster surfaces from point data.

Buffer generation creates zones of a specified distance around raster features, often used in proximity analysis and environmental impact studies.

Raster to vector conversion is the transformation of raster data, such as pixels, into vector format, such as points, lines, or polygons, facilitating analysis in different GIS applications.
