Question 1

Do I need an account to use the map tools?

Accepted Answer

No. Core tools such as geocoding, elevation, world map and my location work without signing in. An account is only needed for optional private history and share management features.

Question 2

Which coordinate system do you use?

Accepted Answer

WGS84 (EPSG:4326) only for display and API results. We do not apply GCJ-02 / BD-09 offsets used by some regional map apps.

Question 3

Are elevation and weather the same data source?

Accepted Answer

No. Elevation comes from our local DEM estimate. Weather is fetched separately from WeatherAPI when you view weather for a place.

Question 4

Why are some searches rate limited?

Accepted Answer

Upstream geocoding providers (LocationIQ / Nominatim) enforce fair-use limits. Caching and daily quotas help keep the free service available for everyone.
