+
+GMTSAR is an open source (GNU General Public License) InSAR processing system designed for users familiar with Generic Mapping Tools (GMT). The code is written in C and will compile on any computer where GMT and NETCDF are installed. The system has three main components:
+ - a preprocessor for each satellite data type (ERS-1/2, Envisat, ALOS-1, TerraSAR-X, COSMOS-SkyMed, Radarsat-2, Sentinel-1A/B, and ALOS-2) to convert the native format and orbital information into a generic format;
+ - an InSAR processor to focus and align stacks of images, map topography into phase, and form the complex interferogram;
+ - a postprocessor, mostly based on GMT, to filter the interferogram and construct interferometric products of phase, coherence, phase gradient, and line-of sight displacement in both radar and geographic coordinates;
+GMT is used to display all the products as pdf files and KML images for Google Earth. A set of shell scripts has been developed for standard 2-pass processing as well as geometric image alignment for stacking and time series. Users are welcome to contribute to this effort.

+
+## Docker Image
+
+Download and launch the Docker image to open "ubuntu" user terminal using the commands below:
+```
+docker pull mobigroup/gmtsar
+docker run -it --name gmtsar docker.io/mobigroup/gmtsar
+```
+
+or built the image yourself locally using Docker file inside the repository and open the terminal:
+```
+docker build --no-cache -t gmtsar . -f gmtsar.Dockerfile
+docker run -it --name gmtsar docker.io/library/gmtsar
+```
+To download orbit data for ERS and Envisat (6 GB) enter this command:
+```
+download_orbits.sh
+```
+
+Note: use no-password "sudo" for all operations requiring "root" user access.
+
+Note: to build the multi-arch images and share them to DockerHub use the command below with your own repository name:
+
+```
+docker buildx create --name gmtsar
+docker buildx use gmtsar
+docker buildx inspect --bootstrap
+docker buildx build . -f gmtsar.Dockerfile \
+ --platform linux/amd64,linux/arm64 \
+ --tag mobigroup/gmtsar:2022-10-11 \
+ --tag mobigroup/gmtsar:latest \
+ --pull --push --no-cache
+```
+
+## Run Examples
