Orthophoto The high-resolution orthomosaic generated by the UAV-acquired images allowed The high-resolution orthomosaic generated by the UAV-acquired pictures allowed mappingof both ecological zones represented by S. alterniflora and S. pumilus (Figure 5). mapping of each ecological zones represented by S. alterniflora and S. pumilus (Figure 5). The two vegetated regions have been compared using the corresponding 2012 GYKI 52466 Formula planting plan as well as the two vegetated locations were compared using the corresponding 2012 planting strategy and elevations supplied by the USACE. Comparisons of vegetation condition were made more than elevations offered by the USACE. Comparisons of vegetation condition had been created more than about one particular about 1 year employing the UAV surveys, and modifications in vegetation distributions were comusing the UAV surveys, and changes in vegetation distributions had been pared over a seven-year time frame, from 2012 to to 2019, applying UAV imagery and ascompared more than a seven-year time frame, from 2012 2019, working with thethe UAV imagery and constructed map (Figure five). as-built map (Figure 5).Figure 5.

The white continuous line displays the original boundary between the S. pumilus (high marsh) and S. alterniflora (low marsh). Light green in plot C shows an invasion of the S. alterniflora in to the higher marsh zone of Cell 1B, reflected as a dark green.Remote Sens. 2021, 13,Figure five.

The white continuous line displays the original boundary between the S. pumilus 9(higher of 19 marsh) and S. alterniflora (low marsh).
