Apply graduated symbology with blue-to-red color ramps to visualize flow velocity differences. Overlay flow accumulation networks to highlight major drainage channels and tributaries for comprehensive watershed analysis.

Highlight Catchment Areas and Basin Boundaries

Delineate watershed boundaries using pour point analysis tools in ArcGIS or QGIS’s SAGA watershed delineation algorithms. You’ll define catchment polygons that represent drainage areas contributing to specific outlet points. Color-code basin boundaries with distinct hues to separate major watersheds from sub-basins. Add elevation contours and ridge lines to emphasize topographic divides that control water flow between adjacent drainage systems.

Visualize Flood Risk Zones and Water Accumulation

Create flood inundation maps using HEC-RAS modeling results imported into your GIS environment. You’ll classify flood zones by return periods using standardized FEMA color schemes for 10-year 50-year and 100-year events. Overlay water accumulation hotspots derived from flow accumulation analysis to identify areas prone to ponding. Include infrastructure elements like bridges culverts and storm drains to show potential bottlenecks during flood events.

Build Elevation Profile Cross-Sections for Engineering Projects

Engineering projects require precise elevation data to assess feasibility and design constraints. Cross-sectional profiles reveal critical terrain characteristics that influence construction costs and project viability.

Extract Detailed Topographic Profiles

You’ll create accurate elevation profiles by drawing polylines along proposed routes using the Profile tool in ArcGIS Pro or the Terrain Profile plugin in QGIS. Import high-resolution LiDAR data with 1-meter vertical accuracy to capture detailed surface variations including embankments and cuts. Export profile data as CSV files for engineering calculations and include both existing ground elevations and proposed grade lines to visualize cut-and-fill requirements.

Compare Multiple Route Alternatives

You can evaluate different alignment options by generating multiple elevation profiles within the same project workspace. Overlay profiles in ArcGIS Pro’s chart properties or use QGIS Profile Tool to display concurrent routes with distinct colors and line styles. Calculate grade percentages for each alternative and identify steep sections exceeding 8% that require additional engineering considerations. Export comparative charts showing elevation differences between routes to support decision-making processes.

Integrate Infrastructure Planning Elements

You’ll enhance profiles by incorporating utility crossings and existing infrastructure using feature overlays in your GIS software. Add bridge locations where profiles cross waterways and mark areas requiring retaining walls or special foundations based on slope analysis. Include right-of-way boundaries and property lines to identify potential acquisition needs. Layer geological data from state surveys to highlight rock outcrops or unstable soils that affect construction methods and costs.

Design contour animations that gradually reveal elevation patterns by controlling interval visibility. Start with major contour lines at 100-foot intervals, then progressively add intermediate contours at 50-foot and 20-foot intervals. Use ArcGIS Pro’s Time Slider or QGIS Temporal Controller to sequence the appearance of different contour sets. Apply distinct line weights and colors for each interval level to help viewers understand elevation relationships and topographic complexity as detail increases.

Animate Elevation Changes Over Time

Build temporal animations showing how terrain features evolve through geological or environmental processes. Import multi-year DEM datasets from USGS 3DEP to track changes in coastal erosion, volcanic activity, or mining operations. Configure time-enabled layers in ArcGIS Pro with date fields, then export frame sequences showing contour line shifts over decades. Use graduated symbology to highlight areas of significant elevation change, making geological processes visible through dynamic contour movement patterns.

Add Interactive Learning Elements

Integrate clickable hotspots and pop-up information panels within your contour animations for enhanced educational value. Embed elevation readouts, slope calculations, and terrain feature explanations using ArcGIS Online Web AppBuilder or QGIS2Web plugins. Include measurement tools that let students calculate distances between contour lines and determine gradient percentages. Add layer toggle controls allowing learners to switch between different contour intervals, satellite imagery, and shaded relief to reinforce topographic interpretation skills.
