Ashton elevation grid

Digital Elevation data record the terrain height variations from the processed point- or line-located data recorded during a geophysical survey. This Ashton elevation grid is elevation data for the Ashton, WA,1994. This survey was acquired under the project No. 623 for the geological survey of WA. The grid has a cell size of 0.00083 degrees (approximately 91m). This grid contains the ground elevation relative to the geoid for the Ashton, WA,1994. It represents the vertical distance from a location on the Earth's surface to the geoid. The data are given in units of meters. The processed data is checked for quality by GA geophysicists to ensure that the final data released by GA are fit-for-purpose.
