Topography instrumentation,The previous chapters have made references to surface data without going into any detail on the techniques used to measure surfaces, their advantages and the nature of the data captured. There are a wide variety of data capture techniques each with its advantages and limitations — these will be considered in this chapter.

Surface Topography Filtering,We have seen from Chapter 3 that measuring a surface implicitly involves filtering the surface. In other words it is impossible to measure a surface without applying a filter to the measurand. Examples of filters encountered in surface topography measurement systems include:

Surface characterization using neural networks,een a dramatic shift from 2- to 3-D analysis, and although the uptake of 3-D technology is still disappointing within industry, there is some evidence to suggest that 3-D systems will become widespread in industry even in the near future (Dong ., 1994a).

Effect of Farm Manure on Dissolution of Underlying Carbonate Rocks and Atmospheric CO2 Source/Sink,f soil profile in karst area in Guiyang city, Guizhou province; the dissolution amounts of tablets, soil CO., soil pH, and soil water content were monitored. The results show that manure addition decreases the dissolution rate of carbonate rocks, and that dissolution amount of limestone and dolomite
