“…Temporal variability is often a challenge of wetland classification since some classes are changing dynamically their condition [14,[51][52][53], e.g., through flooding, pronounced dry phases, or cropping cycles. Several image compositing approaches were developed in the past years [54][55][56][57][58][59][60][61][62]. The general idea of those methods is to select on a per-pixel basis the most suitable observations from a predefined selection of images that fulfill different quality criteria and represent spectral reflectance of one particular day of year in the best way.…”

“…Landsat data were corrected to surface reflectance [17,18] using the USGS Earth Resources Observation and Science (EROS) Center Science Processing Architecture (ESPA) [19] processing system (https://espa.cr.usgs.gov/, accessed 12 June 2019), reprojected to USA Albers Equal Area Conic, and resampled to 30 m. Using high-performance computing architecture, multiple Landsat scenes were stacked and ranked pixel by pixel to produce a cloud-free image composite. This process, known as best-pixel image compositing [11], was conducted within a tiling framework covering the extent of both prototyping locations (see Figure 1 for NW and GC LANDFIRE tiles). A total of 7637 and 27,921 Landsat scenes were processed for the GC and NW, respectively ( Figure 2).…”

“…The first was previously developed by LANDFIRE to be used for mapping disturbance (i.e., LF 2010, LF 2012, and LF 2014) and is based upon imagery from two periods of time within the same calendar year, including early season (Julian days 135-227) and late season (Julian days 228-306) composites. Landsat imagery within the Julian date ranges is obtained from the Landsat archive (https://earthexplorer.usgs.gov/, accessed 11 June 2019) for each year of interest, placed in a virtual stack of all images, and processed to the specifications established in the best-pixel algorithm [11]. As an example, to identify disturbance in 2015, early and late season best-pixel composites are produced by year for 2014, 2015, and 2016.…”
