| Positional Accuracy | Overall approximate use scale 1:250,000. While some segments (esp. shoreline segments) have been digitizied in a larger use scale, most boundary segments are only in approx. 1:250,000 scale. |
| Logical Consistency | In the OpenStreetMap database, a boundary segment between Myanmar and Thailand is explicitly marked as "contested". We choose the "Myanmar claimed" tagged contested boundary segment for this dataset. |
| Completeness | Completed |
| Process Step | Processing: - Download administrative boundary features for a buffered area of interest encompassing Myanmar from OpenStreetMap using HotExport Tools (https://export.hotosm.org/en/v3/); - On-screen digitizing of shoreline segments based on Sentinel-2 March 2020 satellite imagery in a use scale of approx. 1:25,000; - Conversion of OSM boundary data to line-segments; - Removal of boundary line segments representing contested areas claimed by other countries; - Semi-automated removal of shoreline segments from OSM boundary data; - Fusion of OSM boundary data with improved and consistent shoreline geometry and generation of township boundary polygons; - Generation Myanmar administrative units database table and point geometry dataset with (incl. Myanmar and romanized spelling & place codes) based on Wikipedia and GAD township profiles; - Spatial join of township polygons with the Myanmar administrative units database table/points; - Aggregation of the township polygons to District and State & Region polygons based on the hierarchy specified in the Myanmar Administrative Units table. |
