If you’ve ever tried to copy coordinates from kataster.ee or the Maa-amet geoportal directly into Google Maps and ended up in the wrong place, the reason is not incorrect data — it’s the use of different coordinate systems.
L-EST97 vs WGS84 – what’s the difference?
Kataster.ee and Maa-amet (Land and Spatial Development Board) use Estonia’s official planar coordinate system L-EST97.
Google Maps, however, uses the global geographic system WGS84, based on latitude and longitude.
| System | Where it’s used | Format |
|---|---|---|
| L-EST97 | Kataster.ee, Maa-amet, planning & construction data | X / Y (meters) |
| WGS84 | Google Maps, GPS, mobile navigation | Latitude / Longitude (degrees) |
👉 This is why L-EST97 coordinates cannot be pasted directly into Google Maps — they must be converted first.
Why don’t Maa-amet coordinates work in Google Maps?
Example from kataster.ee:
X: 536865.02
Y: 6568141.79
Google Maps expects:
59.4370, 24.7536
If you enter L-EST97 values into Google Maps:
- the location will be incorrect
- the point may even appear in another country
This is normal and does not mean the cadastral data is wrong.
How to convert coordinates correctly?
You need a coordinate transformation from L-EST97 to WGS84.
This can be done using:
- coordinate conversion tools
- GIS software
- official Maa-amet services
After conversion, the location will be accurate and usable in Google Maps, Waze, and GPS devices.
Why is this important in real estate?
- 📍 Sharing accurate locations with clients
- 🏗️ Checking planning and building permits
- 🚗 Navigation to properties
- 📊 Data analysis and visualization
For real estate professionals, this is a small but crucial technical detail.
Summary
If Maa-amet coordinates don’t work in Google Maps, the issue is not the data — it’s the coordinate system.
✔️ Kataster.ee = L-EST97
✔️ Google Maps = WGS84
✔️ Solution = coordinate conversion
