GRASS GIS

Import LiDAR data into GRASS GIS to create a high-resolution digital elevation model (DEM).

Process the DEM to derive topographic attributes such as slope, aspect, and curvature.

Analyze historical aerial imagery to identify areas of coastal erosion over time.

Model future erosion scenarios based on sea-level rise and storm surge projections.

Visualize the results in 3D to communicate the risks to stakeholders.

Collect historical land use data from satellite imagery and municipal records.

Create a spatial model of urban growth using GRASS GIS's cellular automata and agent-based modeling tools.

Calibrate the model using historical data and validate its accuracy.

Simulate future urban growth scenarios based on different policy options.

Assess the environmental impacts of urban expansion, such as deforestation and water pollution.

Gather species occurrence data from field surveys and museum records.

Collect environmental data such as climate, elevation, and land cover.

Use GRASS GIS's statistical modeling tools to relate species occurrence to environmental factors.

Create a predictive map of species distribution based on the statistical model.

Validate the accuracy of the map using independent data.

Download global hydrological data from public sources (e.g., NASA, USGS).

Process the data using GRASS GIS's hydrological modeling tools.

Simulate river flow, evapotranspiration, and groundwater recharge.

Assess the impacts of climate change on water resources.

Visualize the results using maps and charts.

Collect data on agricultural practices, soil types, and weather patterns.

Use GRASS GIS's hydrological modeling tools to simulate runoff generation and transport.

Model the transport of pollutants from agricultural fields to water bodies.

Assess the impacts of runoff on water quality.

Develop strategies to reduce agricultural runoff and improve water quality.

Import DEM into GRASS GIS.

Use r.watershed module to delineate watershed boundaries and stream networks.

Refine stream networks using v.stream.snap to ensure connectivity.

Generate flow accumulation and flow direction maps.

Extract river networks and create vector layers representing streams and water bodies.
