# LGA Value Risk vs Avg
LGAs with emissions > 1.5 standard deviations above the mean are flagged as potential anomalies — possible indicators of unauthorized dumping activity.
LGAValueZ-ScoreRisk
LGAs whose centroids fall within buffer zones of identified landfills. Closer proximity = higher potential exposure.

Landfills — 2025 Status
Current status of all identified landfill sites in Lagos State. Gas emission levels are derived from the nearest LGA's 2025 Sentinel-5P data.
Gas Emissions
Statewide average emission levels for all 3 gases (2018–present). Shows whether Lagos emissions are improving or worsening over time.
Scatter plot of two selected gases per LGA for the selected year. LGAs far from the cluster may indicate unusual gas profiles — potential anomaly indicators.

Lagos Environmental Risk Dashboard

Sentinel-5P  ·  2018–present  ·  Lagos State, Nigeria

An interactive GIS dashboard for analyzing and visualizing dumpsite gas emissions (CH₄, NO₂, CO) across Lagos State. Built to support environmental monitoring and evidence-based decision-making around landfill impact zones.

Objectives
01Map existing landfill sites across Lagos State
02Classify gas emission concentrations and analyze spatial distribution
03Apply buffer analysis (100m / 500m / 1km) to assess emission impact zones
04Deliver an interactive GIS dashboard for visualization and analysis
05Detect anomalous emission areas as indicators of potential unauthorized dumpsites

Update Emission Data
Upload a CSV to update LGA emission values.
Format A (pre-joined): lganame, year, ch4, no2, co, isi, hotspots
Format B (point-based): longitude, latitude, year, ch4, no2, co, isi, hotspots
Update Landfill Sites
Upload a GeoJSON FeatureCollection of Point features to replace the current landfill dataset. Each feature should have Name and Status properties.
Update Places
Upload a GeoJSON FeatureCollection to replace the places / settlement labels layer. Any geometry type is accepted.
