I need to develope a subsurface sediment map of the Salton Sea, California using data generated by the "Quester Tanget" sonar classification device. The device analyses the sonar waveform to predict sub sea bottom characteristics. The sample rate of the device produce site data seperated by 20 cm or so along transect lines.
Output stream consists of 3 floating point attributes and an class number.
I need to reduce the data to fit an expected resolution of 10 m x 10 m, and interpolate between widely seperated transect lines.
What is the correct sequence to reduce the densely packed transect data to a surface. My test data set shows the sample points within a neighborhood may belong to several classes. I will need to produce a calculated proportion within a class for a neighborhood.
This would be similar to the reduction of bathymetry or other closely packed transect data to a larger cell size, with the exception that simple decimation of the data set is not accurate.
