QSCAT (QGIS Shoreline Change Analysis Tool) is an open-source shoreline change analysis (SCA) tool for QGIS that builds upon the foundations set by DSAS. It prioritizes speed, user-friendliness, and resource efficiency, making it a top choice for SCA research.
QSCAT was initially developed by UP-MSI CoastER team for a government-funded initiative to establish coastal erosion trends in Region 1, Philippines. The team originally utilized DSAS for analysis but transitioned to QSCAT due to its enhanced features and capabilities. While we have yet to test QSCAT extensively in other regions, its design suggests potential applicability to various coastal areas.
QSCAT is currently unstable, so please expect for potential bugs and issues. In the meantime, we kindly request your assistance in reporting any problems you encounter at QSCAT GitHub Issues (https://github.com/qscat/qscat/issues). Thank you for your cooperation!

Shoreline Change | Computes shoreline change statistics: shoreline change envelope (SCE), net shoreline movement (NSM), end-point rate (EPR), linear regression rate (LRR), and weighted linear regression rate (WLR). |
Area Change | Calculates length and area of accreting, stable, and eroding coastal segments. |
Forecasting | Predicts future shoreline positions including uncertainty areas. |
Automator | Automates manual repetitive tasks. |
Visualization | Visualizes shoreline and area change, forecasting results in the map for easy interpretation. |
Summary Report | Generates a comprehensive summary report of the results. |
