Multi-temporal Aerial Imagery of Philippine Rivers, 2019-2020

Multi-temporal aerial imagery of rivers in the Philippines, 2019-2020 contains orthorectified aerial imagery for two river segments. The data covers the Bislak River downstream and the Abuan, Bintacan, and Pinacanauan de Ilagan Rivers confluence, captured during repeat surveys in 2019 and 2020. The resulting orthoimagery has a 0.2-meter spatial resolution with RGB bands.

Use Cases

• Analyze river channel morphology changes between 2019 and 2020 using multi-temporal orthoimagery.
• Map floodplain extent and surrounding land cover from the 0.2-meter resolution RGB imagery.
• Monitor environmental changes at the confluence of the Abuan, Bintacan, and Pinacanauan de Ilagan Rivers using spatially corrected data.

Strengths

• Orthoimagery has a high 0.2-meter spatial resolution.
• Provides multi-temporal coverage from repeat surveys in 2019 and 2020.
• Covers two distinct river segments, including a major confluence area.

Limitations

• Imagery is limited to two specific river segments in the Philippines, not a national-scale resource.
• Data is temporally limited to two survey years, 2019 and 2020.
• The dataset does not include derived features like land cover classifications or water masks.
