Data Structure

The plugin supports both vector and raster data.

Vector data

A vector file (e.g., a shapefile or geopackage) containing time series data can be visualized in InSAR Explorer. The file should have the following attributes:

Field Name	Description
velocity, VEL, or mean_velocity	Or a similar field containing the InSAR velocity data.
DYYYYMMDD or YYYYMMDD or D_YYYYMMDD	Multiple fields for time series data, where YYYYMMDD is the date of the data, e.g., D20190101, D20190201, etc.
Additional fields	Optional fields for additional data, such as coherence, errors, etc.

Raster data

The plugin also supports raster data in GMT GRD format for specific time series outputs. For each time stamp, the plugin expects a separate raster file with the following naming convention: timeseries-YYYYMMDD*.grd or YYYYMMDD_*.grd. The velocity file should be named vel_*.grd or velocity_*.grd.

-| timeseries files/
  -| vel_*.grd
  -| YYYYMMDD_*.grd
  -| YYYYMMDD_*.grd
  -| ...
  -| timeseries-YYYYMMDD*.grd
  -| timeseries-YYYYMMDD*.grd
  -| timeseries-YYYYMMDD*.grd
  -| ...

Once one of the grd files is opened in QGIS, the plugin automatically detects the associated time series files and handle them accordingly.
