Geodetic Modeling Software in Matlab.zip

## Geodetic modelling software in Matlab ### 1. Installation #### 1.1 Setup environment path Add the following to your _~/.bashrc_: ``` alias matlab=/Applications/MATLAB_R2019a.app/bin/matlab export MATLAB_USE_USERPATH=1 ##--------- GEODMOD ------------------## export GEODMOD_HOME=~/Documents/test/test1/geodmod export GEODMOD_TESTDATA=~/Documents/testdata/geodmod export GEODMOD_TESTBENCH=~/Downloads/TESTBENCH ``` #### 1.2 Download ``` git clone https://github.com/geodesymiami/GeodMod.git $GEODMOD_HOME ``` #### 1.3 Setup matlab path Add the following to your _startup.m_ file in _USER/matlab_ for Matlab to initiate the configuration: ```matlab %% Setting for GeodMod disp('Setting paths for geodmod...') run( [ getenv('GEODMOD_HOME') filesep 'addpath_geodmod'] ) ``` ### 2. Test Run Download test data ``` mkdir -p $GEODMOD_TESTDATA cd $GEODMOD_TESTDATA wget https://zenodo.org/record/3348961/files/geodmod_testdata.xz tar -xvJf geodmod_testdata.xz ``` Start matlab program from terminal to initiate the environment variables defined above. ``` matlab >>geodmod Darwin.min >>geodmod Wells.min ``` ### 3. Tips You can disable most of the plotting (quick runs) using: ``` inverseopt.QuickStop = true plotthemodelopt.DoIt = off plotsurface3dopt.DoIt = off inverseopt.distribopt.DoIt = off ``` ### 4. Dislocation convention Geodmod uses the same dislocation code as GBIS. See the GBIS manual for definition of the parameters. In contrast to GBIS geodmod always requires the strike-slip, downdip and opening component. GBIS requires for a fault onlt the first two and for a dike the last (the unused components are set to zero internally). The relationship between dip and strike is the same with that of GBIS(right hand rule); But for the middle point (Xiaoran): In Geodmod, the middle point always loated at the lower edge; In GBIS, the location of middle point has relationship with the dip(negtive dip means middle point locates at the upper edge while positive dip means middle point locates at the lower edge). ### 4.
