This enhancement would allow for visualization of PS locations created by an external software package (e.g., StaMPS). In order to implement this, the existing source code used for visualizing ground control points (GCPs) and (speckle tracking) displacement maps can be reused. Note, however, that most persistent scatterer interferometry (PSI) applications require PS locations be exported in non-radar coordinates (e.g., latitude/longitude) with subpixel accuracy (in azimuth and range coordinates). This is well supported by other open source projects, such as QGIS (https://qgis.org/) or Kepler.gl (https://kepler.gl/). The visualization will be implemented in SNAP however, as identified in the risks section of this proposal, there may be performance issues for very large number of PS points or large AOIs. Under those limitations, we will include instructions in the tutorial on how users can use external tools such as QGIS and Kepler for visualization.
