Daysymetric Mapping Using National Structure Inventory Daysymetric Mapping Using National Structure Inventory

This code uses a dasymetric mapping technique to distribute attribute values defined at the zip code level to new attribute values at the census county level. The attribute to be mapped is the number of people in each zip code who are using durable medical equipment such as a wheelchair. The National Structures inventory point data is used as the mechanism to distribute the zip

Matlab code to count acoustic impulses from coarse sediment particle collisions during sediment transport in rivers Matlab code to count acoustic impulses from coarse sediment particle collisions during sediment transport in rivers

This software release is a Matlab code that can be used to count acoustic impulses from coarse sediment particle collisions during sediment transport in rivers. The code also uses either a user defined threshold (preferred) or threshold computed from the overall noise of the audio files. Counts impulses exceeding the threshold which are assumed to be particle impacts of course (gravel...
