An official USGS software project is code reviewed and approved at the bureau-level for distribution.
SPECtrum Processing Routines (SPECPR)
SPECPR is an Interactive One Dimensional Array Processing System, with the tools needed for reflectance spectroscopy analysis. It also has tools to do a lot of other tasks and analyses of x,y paried data.
SeisRisk III
Seisrisk III is the last published version of a series of programs used to produce probabilistic earthquake ground motion hazard maps for the United States from 1972 to 1992.
Slick Package
The slick package uses fault slip data (either field observations or from focal mechamism) to find the stress tensor that best explains the observations. Inputs are the orientation and slip direction of a set of fault planes.
BAND2: A Computer Program for Sample Size Computations for Banding Studies
Computes the number of animals that must be banded in order to achieve a specified level of precision for survival rates estimated using band recovery models.
POWER
Computes the power of between-model likelihood ratio tests.
MULT
Computes estimates of survival and temporary emigration under the "Open Robust Design".
RELEASE
Computes estimates of survival and capture probability for capture-recapture experiments on open animal populations.
CAPTURE
Computes estimates of capture probability and population size for "closed" population capture-recapture data.
SURVIV
Computes estimates of survival (or any model parameter) with multinomially distributed data.
MAYFIELD
Computes estimates of daily survival rate for nest visitation data.
CAPQUOTA
Computes expected coefficients of variation of survival and capture probability for use in the design of capture-recapture-resighting experiments.
SPECRICH
Computes "species richness" or total number of species from emperical species abundance distribution data.
