Specifically, it captures the exact location (latitude and longitude) as well as changes in the built-up area of each of SEZ over time. The change in built-up area over time is calculated from manually drawn polygons around the built-up area of each SEZ on historical satellite imagery from Google Earth Pro. We provide access to these polygons for each SEZ in the KLM file ‘Vietnam SEZ Polygons.klm’ and the built-up area over time for each SEZ in the STATA file ‘Vietnam SEZ Built-up Areas.dta’. We also provide access to additional metadata on each SEZ – including zone type, focus sector, and year of approval/establishment – in the Excel file ‘Vietnam SEZ Metadata.xlsx’.The dataset contains detailed geographic information on more than 600 Special Economic Zones (SEZs) in Vietnam.
