Introduction
π-RATE (Poly-Interferogram Rate And
Time-series Estimator) is a Matlab-based
software package that estimates displacement rate, time series and their
associated uncertainties from a set of unwrapped InSAR images. It
originated from the multi-interferogram method proposed by Juliet Biggs
and her colleagues at the University of Oxford (Biggs et al., 2007). The
method was then improved by John Elliott, Hua Wang and their colleagues
(Elliott et al., 2008; Wang et al., 2009). Tim Wright developed some
scripts, and led the whole period of π-RATE's development. The first
formal version of π-RATE was tested within Tim Wright's InSAR group.
The codes and documentation have been prepared for public release by Hua
Wang.
π-RATE is designed to work with data produced
by ROI_PAC. For other InSAR software, we recommend to convert your data
to ROI_PAC's RMG and RSC format. For all the scripts in π-RATE, you
can type 'help scriptname'
for a brief description of its usage. π-RATE
can only be used for academic purpose, and MUST NOT be used as a part of
any commercial package.
Download
and Install
To install π-RATE, you
need create a folder, e.g. pirate, under certain directory. Please refer
to the manual
for the usage in detail.
- Download π-RATE and the manual from the University
of Leeds.
mget http://homepages.see.leeds.ac.uk/~earhw/pirate/pirate_v2.0b2.tar
- Make a folder for the scripts
mkdir $HOME/pirate
cd $HOME/pirate
tar -xvf pirate_v2.0b2.tar
- Setup environment in your .cshrc
file
setenv PIRATEHOME $HOME/pirate/
source ~/.cshrc
- addpath
for π-RATE in Matlab
>> addpath(genpath(getenv('PIRATEHOME')))
