Heatmap Layers

The Heatmap Layers map provides four independently toggle-able data overlays on a single Singapore basemap: Transit Proximity (red-intensity, distance to nearest MRT), Walkability Score (green-intensity, based on POI density across 7 amenity categories), CBD Distance (red-intensity, straight-line distance from Raffles Place), and Amenity Density (purple-intensity, concentration of hawker centres, supermarkets, clinics, parks, and schools). Each layer uses a kernel-smoothed heatmap — brighter and more intense means a higher score on that dimension. Multiple layers can be enabled simultaneously to find areas that score well across several dimensions at once.

You can access this map on ShiokNest under the Maps tab in the Data Layers section. Toggle individual layers on or off from the control panel in the top-right corner of the map. The basemap remains readable beneath the overlays so street names and landmarks are always visible. Data sources: transit proximity from OneMap MRT station coordinates; walkability from ShiokNest's pre-computed walkability scores (updated quarterly); amenity density from OneMap POI data updated monthly. This map pairs naturally with the Walkability Score Insight for district-level numeric breakdowns behind the visual heatmap.

Individual property data points — PSF, yield, ShiokNest score — tell you about a specific development but not about the quality of the surrounding area at a city-wide scale. The Heatmap Layers map fills this gap: it shows the spatial distribution of transit, walkability, CBD proximity, and amenity density simultaneously, so you can visually identify which parts of Singapore score well on multiple dimensions at once. The intersection of high-walkability and high-transit-proximity is the sweet spot that typically commands the most stable long-term demand — and this map makes that spatial intersection instantly visible without needing to cross-reference four separate data tables.

The most powerful use of this map is the multi-layer comparison. Enable both Transit Proximity and Walkability simultaneously. Areas that light up intensely on both layers — typically D3 (Queenstown), D12 (Toa Payoh), D13 (Macpherson), and D15 (East Coast) — have genuine dual-premium characteristics. Areas that light up on only one layer require a trade-off: D9/D10 are walkable and transit-dense but very high PSF; parts of D19/D20 have strong transit but moderate walkability due to lower amenity density. The visual overlap (or absence) makes these trade-offs immediately readable without a spreadsheet.

The Amenity Density layer is particularly useful for identifying underrated neighbourhoods. Areas like D20 (Bishan), D13 (Macpherson), and D12 (Toa Payoh) consistently show high amenity density because they have large established hawker centre catchments, mature supermarket penetration, and good school zoning — yet are priced 30–40% below prime CCR districts. For buyers who weight lifestyle convenience equally with prestige location, the amenity density layer identifies these areas as providing CCR-equivalent amenity at OCR pricing.

The CBD Distance layer reveals a "second ring" of districts — D3, D12, D13 — that sit within 5–8km of the CBD (same geodesic band as many RCR addresses) but are priced at OCR levels because they lack the River Valley or Holland Village prestige address. This pricing arbitrage is visible on the heatmap but invisible from a standard portal search filtered by price range. Use the heatmap to identify candidate areas, then validate with the Rental Yield Insight to confirm strong demand fundamentals before shortlisting.
