Data sources
What goes in, and how we handle it.
EmlakIQ ingests from seven source families. Each arrives in a different format — PDF, shapefile, registry extract, API, raster grid. The normalization layer converts all of them to the same evidence schema.
Fragmentation and normalization
The same reality, seven incompatible formats.
| Source family | Raw shape | EmlakIQ normalization |
|---|---|---|
| Cadastral and address records | Inconsistent identifiers, geometry, text | Canonical entity identity |
| Zoning records | Municipal notes, parcel-level rules | Normalized zoning context |
| Building facts | Unit, floor, usage attributes | Physical context profile |
| Risk layers | Fault lines, hazard grids, geological polygons | Risk context fields |
| Market activity | Monthly sales/mortgage/transfer signals | Temporal market context |
| Macro-credit series | TÜİK and BDDK period data | Geography-linked macro overlay |
Source detail
Seven source families.
Source What it provides Format Coverage

Municipal Zoning Zoning plan, floor-area ratios, height limits, approved use PDF, shapefile, portal Major cities
TÜİK Housing starts, building permits, price and rent indices, demographic data Statistical release National, NUTS-2
BDDK Mortgage volumes, credit-to-value ratios, sector exposure metrics Statistical release National
MTA Geological units, lithology, landslide and subsidence risk layers Raster / shapefile National
EFEHR Probabilistic seismic hazard grids (PGA at 475-year return period) Raster grid Regional (Turkey)
Project Inventory New development projects, phase timelines, unit counts, developer data Structured manifest İstanbul (expanding)
What we cannot provide
Honest about gaps.
- Real-time transaction prices — Turkish registry does not publish sale prices at record level
- Title history depth beyond current registry state
- Building age for unlicensed or unregistered structures
- Zoning detail outside major cities where municipal data is not yet structured
- Seismic microzonation below district resolution in non-pilot geographies
