GMTSAR

GMTSAR provides time series data in raster grd format. This data can be processed in InSAR Explorer using one of two methods:

Method 1: Use the grd Files Directly

You can directly use the raster grd files created by GMTSAR in InSAR Explorer. The expected directory structure for the grd files is as follows:

-| GMTSAR_output/
  -| vel_*.grd
  -| YYYYMMDD_*.grd
  -| YYYYMMDD_*.grd
  -| ...

To use this method: 1. Ensure the grd files associated with the time series are located in the same directory as the vel_*.grd file. 2. Open the original vel_*.grd file created by GMTSAR in QGIS. 3. Set the correct Coordinate Reference System (CRS) for the QGIS project (typically WGS 84).

InSAR Explorer will automatically detect the associated time series files and handle them accordingly.

Method 2: Convert grd to Vector Format

It is possible to convert the time series data from raster grd format to vector formats such as shapefile or geopackage.

Note: You should create the shapefile with proper format as described in Data Structure
