Digital Shoreline Analysis System (DSAS) is a tool developed to calculate shoreline change over time using historical and modern shoreline data. It helps measure how coastlines are shifting due to erosion, sedimentation, or sea-level rise by analyzing geospatial data within a GIS environment.
In Malaysia, DSAS is highly useful for coastal planning, erosion monitoring, and environmental impact studies—especially in areas affected by climate change or development. It provides critical insights into the rate of shoreline movement, helping authorities make better decisions for coastal protection and land use.
At Geotechnica, we use DSAS as part of our coastal and environmental services, combining satellite imagery, aerial data, and GIS expertise to deliver accurate, science-based shoreline change analysis that supports sustainable coastal management.

FAQ
DSAS is a GIS tool that tracks and analyzes shoreline changes over time using geospatial data.
It calculates erosion, accretion, and shoreline movement rates using historical and current shoreline positions.
It helps monitor coastal erosion and supports coastal planning in areas affected by sea-level rise and development.
It uses satellite imagery, aerial photos, topographic maps, and GPS shoreline data.
Accuracy depends on the quality of shoreline data and georeferencing; when done properly, it’s highly reliable.
Coastal engineers, planners, environmental consultants, and government agencies for shoreline management.
Yes, by analyzing long-term trends, DSAS helps forecast future shoreline movement for better risk planning.
No, it works as an extension within ArcGIS to process and visualize shoreline data.
Regular updates (every 5–10 years) are ideal, or after major coastal changes or storms.
We combine DSAS tools with local expertise, remote sensing, and field data for precise shoreline change assessments in Malaysia.
