About WCS Services¶
Gemini Terrain can connect to services that support the WCS protocol (Web Coverage Service). WCS is an international standard for exchanging raster data over the internet, such as elevation models, orthophotos, and other coverage data. Unlike WMS, WCS delivers raw data that can be used further in analyses and calculations.
