What is the difference between raster data and elevation data?

Raster elevation data, by contrast, consist of grids of points at which elevation is encoded at regular intervals. Raster elevation data are what's called for by the NSDI Framework and the USGS National Map. Digital contours can now be rendered easily from raster data.

What format is elevation data stored in?

Elevation data is typically stored in a raster format; however, data managers need to be aware of data stored in irregular, non-cell-based formats. One example is a triangular interpolated network (TIN).

What are the uses of raster data in a GIS?

While the structure of raster data is simple, it is exceptionally useful for a wide range of applications. Within a GIS, the uses of raster data fall under four main categories: A common use of image data in a GIS is as a background display for other feature layers.

What is the raster grid format?

This format consists of a raster grid of regularly spaced elevation values derived from the USGS topographic map series. In their native format, they are written as ANSI-standard ASCII characters in fixed-block format.
