Tip: Some layers and labels show/hide automatically based on zoom level. Zoom in to reveal labels for roads, rivers, survey blocks and parcels.
Parcel Lookup: Type a parcel number or LR number in the top search bar. Auto-complete suggestions appear as you type. Selecting a result highlights the parcel in yellow, flies to its location, and shows a detailed popup with zoning, DC policy, and change-of-user guidance.
Geocoding: Use the geocoding panel to search for places, addresses, or landmarks. Supports live Nominatim suggestions, Arrow Up/Down navigation, Enter-to-select, and a location popup with coordinates.
Coordinate Query: Enter latitude/longitude in the query panel to find the parcel containing that point, or right-click anywhere on the map to copy coordinates or open Google Maps.
The Swipe tool lets you compare two overlay layers side by side on the same map. Open it from the toolbar, select a Left Layer and a Right Layer from the drop-downs, then drag the vertical divider to reveal one side or the other. Floating badges label each side. Click Reset to clear the comparison and restore normal map display.
The Isochrone tool generates reachability zones around a point you choose on the map. Select Driving or Walking mode, then click a location. The tool calculates 5-minute (green), 10-minute (amber), and 15-minute (red) travel-time polygons using OSRM routing. Click Clear to remove the zones.
Open the Filter Builder from the toolbar, choose a layer, set field + operator + value, then apply. Matching features are highlighted with an orange stroke and cyan fill on the map, and hover effects on other layers are suppressed while a filter is active. Clicking Reset removes the filtered layer from the map, restores all styles, and re-enables hover interactions.
Open the Data top-menu panel for interactive dashboards: population density analytics, healthcare facility distribution, and water-supply analytics from the Equitable Water Distribution Programme.
The Attribute Table opens as a floating, draggable panel and gives spreadsheet-style access to layer records without leaving the map.
Supported geometries: Point, MultiPoint, LineString, MultiLineString, Polygon, MultiPolygon.
Upload a WGS 84 (EPSG:4326) GeoJSON or JSON file. The app validates the coordinate reference system, adds features to the map, and zooms to the uploaded extent. Use the Clear Upload button to remove them.
The print control offers Auto, Landscape, Portrait, and Custom (A4) modes. Map controls and the sidebar are temporarily hidden during print.
The Share button copies a URL that encodes the current map centre, zoom, visible basemap, active overlays, searched parcel, geocoded point, and any drawn features. Recipients see the same view when they open the link.
Right-click anywhere on the map to see WGS 84 coordinates with options to copy lat/lng, copy a Google Maps link, or copy both.
The sidebar organises reference content by topic. Click a menu item to expand its section:
Five buttons sit at the top centre of the map. Each opens a slide-in panel:
GIS (Geographic Information System): Tools for analysing, storing, and visualising geographic data.
Base Map: Background reference layer providing geographic context (e.g. satellite, terrain, streets).
Overlay Layer: Additional data drawn on top of the base map.
Choropleth Map: Thematic map using colour gradients to show statistics by area.
Geocoding: Converting addresses or place names into geographic coordinates.
GeoJSON: Open standard (RFC 7946) for encoding geographic features in JSON.
Popup / Tooltip: Information window shown on click (popup) or hover (tooltip).
Zoning: Legal regulations governing permitted land use in specific areas.
Vector Data: Features represented as points, lines, and polygons.
Raster Data: Grid of pixels (e.g. satellite imagery).
Legend: Key explaining map symbols, colours, and classifications.
Scale: Ratio between map distance and real-world distance.
Projection: Method of representing Earth's curved surface on a flat map.
Plot Ratio: Total floor area divided by plot area — controls building bulk.
Ground Coverage: Building footprint divided by plot area — controls open space.

Explore comprehensive datasets through interactive visualizations. The panel includes population density analytics, healthcare facility distribution, and advanced water distribution analytics from the Equitable Water Distribution Programme (June 2025).
Explore Nairobi's population distribution through interactive visualizations. This bar chart shows sublocations by population density (persons/km²), helping identify high-density urban areas for planning infrastructure, housing, and services. Data sourced from 2019 census with growth projections.
Analyze the distribution of healthcare facilities across Nairobi's sub-counties with this interactive chart. Understand the availability of hospitals, health centres, dispensaries, and bed capacities to inform healthcare planning and resource allocation. Data sourced from Nairobi County Health Department records as of 2024.
Advanced visualizations based on the Nairobi City Water and Sewerage Company Equitable Water Distribution Programme (June 2025). The programme shows a rotational supply system in which most areas receive water 2 to 3 days per week, while critical institutions and a limited set of priority zones remain on 24/7 supply. The same source highlights strong geographic disparities, weekend service drops in vulnerable areas, and heavy dependence on major bulk water sources and aging network infrastructure.

Need help interpreting these maps?Nairobi's rapid urban growth, informal settlements, and climate vulnerabilities make remote sensing a powerful tool for evidence-based planning. Satellite data helps track land use/land cover (LULC) changes, urban heat islands (UHI), flood-prone zones, and urban expansion patterns across the city and its peri-urban areas.
These techniques support Nairobi's County Integrated Development Plan, climate adaptation strategies, and efforts to balance urban growth with environmental protection. Explore interactive layers in the map to visualize recent changes.
This section profiles the four key air facilities shaping Nairobi's growth: JKIA, Wilson Airport, Moi Air Base, and Eastleigh Air Base. Their operations influence transport corridors, allowable building heights, compatible land uses, environmental quality, and emergency response planning across the city.
Nairobi's primary international gateway and major economic anchor for logistics, trade, tourism, and employment.
Key domestic and regional airport supporting business travel, medevac, tourism flights, and charter operations.
A strategic defense facility that shapes security zoning, restricted development envelopes, and emergency-readiness networks.
A military aviation site in a dense urban context with direct implications for local land management and public safety planning.
Suggested GIS workflow: layer airport and airbase locations with zoning, density, major roads, and public facilities to identify where growth should be encouraged, constrained, or redesigned.
