Summary
Aquatic features critical to watershed hydrology range widely in size from narrow, shallow streams to large, deep lakes. In this study we evaluated wetland, lake, and river systems across the Prairie Pothole Region to explore where pan-sharpened high-resolution (PSHR) imagery, relative to Landsat imagery, could provide additional data on surface water distribution and movement, missed by Landsat. We used the monthly Global Surface Water (GSW) Landsat product as well as surface water derived from Landsat imagery using a matched filtering algorithm (MF Landsat) to help consider how including partially inundated Landsat pixels as water influenced our findings. The PSHR outputs (and MF Landsat) were able to identify ~60-90% more surface [...]

We used the monthly Global Surface Water (GSW) Landsat product as well as surface water derived from Landsat imagery using a matched filtering algorithm (MF Landsat) to help consider how including partially inundated Landsat pixels as water influenced our findings. The PSHR outputs (and MF Landsat) were able to identify ~60-90% more surface water interactions between waterbodies, relative to the GSW Landsat product. However, regardless of Landsat source, by documenting many smaller (<0.2 ha), inundated wetlands, the PSHR outputs modified our interpretation of wetland size distribution across the Prairie Pothole Region.

Melanie K. Vanderhoof & Charles R. Lane (2019) The potential role of very high-resolution imagery to characterise lake, wetland and stream systems across the Prairie Pothole Region, United States, International Journal of Remote Sensing, DOI: 10.1080/01431161.2019.1582112
The purpose of this analysis was to enhance our understanding of where pan-sharpened high-resolution imagery, relative to Landsat imagery, could provide additional data on surface water distribution and movement, missed by Landsat. To this end we mapped surface water with high-resolution, commercial imagery and Landsat across a total of 7 Prairie Pothole Region sites representing wetlands, lakes, and rivers, and a total of 13 dates (2 dates per site).
