The process of draping in GIS primarily involves which of the following?

The process of draping in GIS involves applying z-values to match terrain elevation. Draping is a technique used to visualize two-dimensional data over a three-dimensional terrain model. By assigning z-values to the data, such as raster images or vector features, they accurately reflect their respective locations on the terrain, allowing for a more realistic representation. This process is essential for applications such as overlaying satellite imagery on a digital elevation model, where the variations in terrain are significant, enabling better analysis and interpretation of geographical data in relation to elevation.

Enhancing color palettes of images typically pertains to image processing rather than the draping process itself. Creating 3D models of vector features can involve various techniques but is not specifically tied to the draping concept, which focuses on aligning 2D data with 3D terrain. Mapping historical data points onto current layouts may involve visual interpretation but does not specifically relate to the technique of draping, which is concerned with the integration and visualization of elevation data.
