FRAME guided instructions
From planning question to usable evidence
Choose the FRAME workflow that matches your question, follow the controls in order, and record the scenario, units, source, and limitations before using a result.
Quick start
Use the same four-step method in every FRAME tool
Start with the decision question, not with a layer name.
-
1
Name the question
Define the place, event or future horizon, and the decision that needs evidence.
-
2
Select the workflow
Use observed flood, future scenarios, plan screening, or FRAME products.
-
3
Inspect map and statistics
Check the legend, units, selected area, table, chart, and difference values together.
-
4
Record context
Save the full scenario label, data status, source date, threshold, and relevant caveats.
Workflow chooser
Open the tool that answers your question
Each option below links directly to the working local module.
Compare flood scenarios
Compare pathways, time horizons, flood depth, urban growth, and commune flood extent.
Open Scenario Explorer
Review the 2025 flood
View the SAR-derived likely flooded area for 26 October 2025 and its publication status.
Open Flood 2025
Screen plan exposure
Overlay LUP 2030 with a modelled flood scenario and rank affected classes or polygons.
Open planning workspace
Inspect LUP 2030
Review planning groups, source classes, coverage metrics, and the largest detailed classes.
Open LUP 2030
Find safe-parking routes
Search 147 designated road segments and read the English instruction for warning level III.
Open safe parking
Review water quality
Explore indicators, sampling rounds, location histories, a data matrix, and downloads.
Open water quality
Explore FRAME products
Open safe-parking guidance, EBA and ECA adaptation evidence, or water-quality estimation.
Open productsWorkflow 1
Compare two future flood scenarios
Use Scenario Explorer when the question depends on different climate pathways, development assumptions, or time horizons.
Open Scenario Explorer1Choose a location and configuration
- Use Search place or district to zoom to a named area.
- Select a Flood event.
- Choose SSP, RCP, and Time horizon from the registry-backed menus.
- Read the complete selection before assigning it to a scenario window.
2Assign Scenario 1 and Scenario 2
- Select the first configuration and press Set Scenario 1.
- Change one or more pathway or horizon values.
- Press Set Scenario 2.
- Confirm the full labels above the left and right map windows before interpreting differences.
3Compare map patterns
- Drag the vertical divider to reveal more of either scenario.
- When the divider has keyboard focus, use the arrow keys for controlled movement.
- Read flood depth from the shared six-class legend in metres.
- Select an urban-growth layer when needed. Select the active option again to turn it off.
- Expand Additional layers to show or hide reference boundaries.
4Read commune statistics
- Select a commune on the map to open its Scenario 1, Scenario 2, and Difference values.
- Use the table below the map to compare all communes horizontally.
- Rows use the actual selected scenario names, not generic scenario labels.
- Flood extent is reported in km² from depth cells above 0.10 m.
Interpretation: A larger difference indicates more modelled flooded area, not a property-level probability or a real-time warning.
Workflow 2
Review the 2025 observed flood candidate
Use Flood 2025 to inspect the SAR-derived likely flooded area for 26 October 2025.
Open Flood 2025Check the status first. The page identifies the map as a candidate layer pending approval.
Pan and zoom. Use the map to inspect the spatial pattern around Hue City and the coastal lagoon.
Read the legend literally. The displayed class is likely flooded on 26 October 2025.
Carry the source note forward. Include the date, SAR classification method, and candidate status in reports.
This map is research evidence. It is not an emergency alert, field-verified boundary, or legal flood-zone product.
Workflow 3
Screen LUP 2030 against flood exposure
Use the planning workspace to identify planning classes and source polygons that overlap a selected modelled flood scenario.
1Select the modelled scenario
Choose Flood event, Climate + development pathway, and Time horizon. Verify the active scenario chip in the toolbar.
2Balance the two map layers
Toggle the flood and plan overlays independently. Adjust Flood opacity and Plan opacity until both patterns remain readable.
3Read the exposure summary
Review flooded plan area, affected share, affected zones, and source plan area. These metrics update with the selected scenario.
4Rank and inspect results
Switch between Classes and Largest polygons. Filter codes or names, change the sort order, and compare the result list with the map.
Exposure is LUP 2030 area sampled where modelled flood depth is greater than 0.10 m. Alignment between the VN-2000 plan and EPSG:32648 flood grid must be validated before release use.
Workflow 4
Use FRAME products
These tools answer different questions. Do not combine their values as if they share one model or unit.
Sampled observations
Water Quality Estimation
- Select a water-quality indicator and sampling round.
- Select a station from the map or station menu.
- Compare its time series with the full observation matrix.
- Download the data bundle when values are needed outside FRAME.
Road economics
Economics of Climate Adaptation (ECA)
- Choose Impact or Benefit view.
- Select the 2050 climate and development pathway.
- In Benefit view, select the adaptation measure.
- Select a ward and compare map, table, and economic summary.
Emergency-planning guidance
Safe Vehicle Parking
- Filter one-side or both-sides parking arrangements.
- Search for a street or route code.
- Select a line and read its translated restriction note.
- Confirm current access, signs, and authority instructions before use.
Catchment measures
Ecosystem-based Adaptation (EbA)
- Select the relevant landscape region.
- Check the associated flood-process tags.
- Shortlist measures by landscape position and planning relevance.
- Open an evidence brief to review benefits, barriers, enablers, and trade-offs.
Before reporting
Interpret and document the result
A map screenshot without its selection context is not a complete FRAME result.
- Question and place: record the decision question and geographic area.
- Selection: copy the full event, pathway, year, measure, indicator, or sampling-round label.
- Units: distinguish metres, km², percentages, parameter units, and economic values.
- Status: identify public, candidate, pilot, or planning-reference evidence.
- Method: include thresholds, spatial alignment, observation coverage, and model assumptions.
- Source: link the relevant FRAME page, catalogue item, or downloaded data bundle.
