## 6 Conclusions  
Taking into consideration the future work and potential based on this study, some remarks are presented. The use of higher resolution datasets could further improve the wildfire impact assessment detail and accuracy, such as high-resolution satellite imagery, DEM, more analytical land cover, and better soil properties datasets in terms of sampling and resolution. Improvements of the utilized methods and comparisons with other related ones could be a step forward in accuracy and validation assessment. Other steps may include a rethinking of the RUSLE erosion risk modeling approach concept based on the literature and a detailed analysis between burn severity and RUSLE erosion risk could aid in finding spatial relations between them [2]. A key future step is the conduction of in situ surveys for the validation of the results derived with the above-mentioned methods regarding burn severity [59] and soil loss. Finally, this work could also be expanded by considering more parameters and it could also be implemented in a similar way for future wildfire events constituting an important tool that not only permits post-fire impact assessment but also creates a useful archive for future studies and decision-making. To sum up, the findings of this study helped in gaining geospatial intelligence over the effects that the 2021 wildfires had in the Attica region. Results regarding burn severity, land cover, and erosion risk, combined in a usable web app, could give a significant advantage to impact assessment research along with the decision making and planning over natural hazards management by stakeholders over the restoration procedures as well as the needed measures in vulnerable areas. In other words, the knowledge that this tool encompasses could help in pinpointing problematic areas and making all the needed post-fire actions more focused and effective. In the region of Attica, the results of this study based on the four studied wildfires showed that in 2021, a large part of the region was burned severely losing important parts of natural ecosystems and these areas are at an increased risk of soil erosion. This situation highlights the need for immediate action that should be taken in those areas by the stakeholders. Lastly, this study, with the presented innovative workflow and holistic approach, tried to highlight the importance of assessing the effects of a wildfire event with the use of Earth observation and GIS-based techniques using a cloud-based platform, in an attempt to share and disseminate the knowledge gained about the impacts on the affected environment.
