Supporting data for Challenges in Estimating Long-Term InSAR-Derived Land Subsidence in the Mekong Delta, Vietnam

This dataset contains supporting shapefiles used in the article "Challenges in Estimating Long-Term InSAR-Derived Land Subsidence in the Mekong Delta, Vietnam". It includes point datasets derived from PS InSAR and SBAS InSAR analyses for the Mekong Delta, prepared for spatial comparison of point distribution and coherence.

The repository contains five shapefiles:

• PS_Mekong_Delta.shp: PS InSAR points for the full Mekong Delta study area, corresponding to the spatial extent shown in Figure 1 of the article;

• PS_Mekong_Delta_selected.shp: PS InSAR points selected for comparative analyses within the five coherence areas shown in Figure 1;

• SBAS_Mekong_Delta.shp: SBAS InSAR points for the full Mekong Delta study area;

• SBAS_Mekong_Delta_selected.shp: SBAS InSAR points selected for comparative analyses within the five coherence areas;

• Coherence_areas.shp: shapefile showing the location of the five selected comparison areas used in the article.

The InSAR attribute tables contain only four fields:
ID: unique identifier,
Lon: longitude,
Lat: latitude,
coh: coherence.

The Coherence_areas.shp attribute table contains only the field: ID.

These files are provided to document the spatial distribution of PS and SBAS points and to support the interpretation of the comparison presented in the article. The dataset does not include displacement velocity values or any additional processed deformation products.
