The dataset contains Interferometric Synthetic Aperture Radar (InSAR)-derived Vertical Land Motion (VLM) measurements and building damage risk maps for five rapidly growing Indian megacities: New Delhi, Mumbai, Bengaluru, Chennai, and Kolkata. Researchers can visualize and extract values, including latitude and longitude information, using ArcGIS, QGIS, or any programming language that supports the ESRI shapefile format.

The data contains 11 files:
1. New_Delhi_VLM_data.csv contains the vertical land motion (VLM) in IGS14 for New Delhi, India. The file has three columns: longitude (deg.), latitude (deg.), vlm(cm/yr).
2. Mumbai_VLM_data.csv contains the vertical land motion (VLM) in IGS14 for Mumbai, India. The file has three columns: longitude (deg.), latitude (deg.), vlm(cm/yr).
3. Bengaluru_VLM_data.csv contains the vertical land motion (VLM) in IGS14 for Bengaluru, India. The file has three columns: longitude (deg.), latitude (deg.), vlm(cm/yr).
4. Chennai_VLM_data.csv contains the vertical land motion (VLM) in IGS14 for Chennai, India. The file has three columns: longitude (deg.), latitude (deg.), vlm(cm/yr).
5. Kolkata_VLM_data.csv contains the vertical land motion (VLM) in IGS14 for Kolkata, India. The file has three columns: longitude (deg.), latitude (deg.), vlm(cm/yr).
6. The file New_Delhi_Buildings_Damage_Risk.zip contains a multi-polygon shapefile representing buildings in New Delhi, each with damage risk assessments across different scenarios. The shapefile includes four fields—Risk_InSAR, Risk_10yrs, Risk_30yrs, and Risk_50yrs—which indicate the building damage risk during the InSAR observation period, and projected over 10, 30, and 50 years, respectively. Each field categorizes risk into five levels: 0 (Very Low), 1 (Low), 2 (Medium), 3 (High), and 4 (Very High), with NaN values where no data is available. The shapefile can be opened and visualized in any GIS software, such as ArcGIS or QGIS, or processed programmatically using tools like Python, R or Matlab.
7. The file Mumbai_Buildings_Damage_Risk.zip contains a multi-polygon shapefile representing buildings in Mumbai, each with damage risk assessments across different scenarios. The shapefile includes four fields—Risk_InSAR, Risk_10yrs, Risk_30yrs, and Risk_50yrs—which indicate the building damage risk during the InSAR observation period, and projected over 10, 30, and 50 years, respectively. Each field categorizes risk into five levels: 0 (Very Low), 1 (Low), 2 (Medium), 3 (High), and 4 (Very High), with NaN values where no data is available. The shapefile can be opened and visualized in any GIS software, such as ArcGIS or QGIS, or processed programmatically using tools like Python, R or Matlab.
8. The file Bengaluru_Buildings_Damage_Risk.zip contains a multi-polygon shapefile representing buildings in Bengaluru, each with damage risk assessments across different scenarios.
