Taiwan (Province of China): Planet Road Surface, Width, and Passability Data

This dataset provides AI-derived road surface type, road width, road surface change
(unpaved to paved), and a Humanitarian Passability Index (HPI) using
PlanetScope satellite imagery (2020 and 2024).

The analysis focuses on arterial roads classified in OSM as motorway, trunk,
primary, and secondary, including their link classes. These road types form
the backbone of long-distance, high-capacity transportation and national connectivity.

Relationship to the Previous Mapillary-Based Dataset

HeiGIT previously released a global dataset based on Mapillary street-level imagery.

- The Mapillary dataset provides detailed ground-level information but has uneven coverage.
- The PlanetScope-based dataset provides near-complete and globally consistent coverage along arterial roads.


Accuracy and Data Quality

The PlanetScope surface model achieved 89.2% accuracy, outperforming OSM surface tags (64.7%).


Summary of Road Statistics

Approximately 0.0177 million km of arterial roads are mapped in OSM.

Based on AI-derived estimates:
- Paved roads: 0.0167 million km (94.1357%)
- Unpaved roads: 0.0001 million km (0.37%)

A total of 0.0082 million km (46.2303%)
lack OSM surface tags.

France: Road Surface Data

This dataset provides detailed information on road surfaces from OpenStreetMap (OSM),
distinguishing between paved and unpaved roads across the region.

Surface information is derived using a hybrid deep learning approach.
For methodological details, see:
http://arxiv.org/abs/2410.19874

Recently, we also published a new country-level dataset based on PlanetScope satellite imagery
with near-complete coverage of all arterial roads. It is available on HDX under the name:
"France: **Planet** Road Surface".
The corresponding paper is available at:
https://arxiv.org/abs/2512.04092


Road Surface Statistics

Approximately 15.7615 million km of roads are mapped in OSM in this region.

Based on AI-derived estimates:
- Paved roads: 6.2742 million km (39.8068%)
- Unpaved roads: 1.0159 million km (6.4456%)

About 9.1728 million km
(58.1974%) of roads lack surface information in OSM.

To reduce this gap, the Mapillary-derived surface dataset provides an additional
0.6775 million km
(7.3862%) of surface information.


Intended Use

This dataset supports transportation planning, infrastructure assessment,
climate emissions analysis, and GIS applications.

Satellite detected water extent over Chittagong division, Bangladesh as of 30 July 2021.

**UNOSAT code: FL20210729BGD**  This map illustrates satellite-detected surface waters in Chittagong division, Bangladesh as observed from a Sentinel-1 image acquired on 30 July 2021 at 05:33 local time Within the analyzed area of about 18,700 km2 and, about 852 km2 of lands appear to be flooded. The water extent appears to have decreased of about 18km2 since 27 July 2021. Based on Worldpop population data and the detected surface waters in the analyzed area, the potentially exposed population is mainly located in the district of Cox's Bazar with ~425,000 people, Chittagong with ~392,300 people.

This is a preliminary analysis and has not yet been validated in the field. Please send ground feedback to United Nations Satellite Centre (UNOSAT).

Important note: Flood analysis from radar images may underestimate the presence of standing waters in built-up areas and densely vegetated areas due to backscattering properties of the radar signal.
