Question 1

What is altitude and how is elevation data measured?

Accepted Answer

Altitude refers to the vertical height of a location above sea level, typically measured in meters or feet. Our altitude finder uses multiple high-precision data sources including OpenStreetMap/Nominatim and AMap APIs to provide accurate elevation information. Measurement accuracy typically ranges from 5-30 meters depending on location and data source availability. This data is widely used in aviation, hiking, weather forecasting, and geographical research.

Question 2

How do I check my current location's altitude? What permissions are required?

Accepted Answer

Simply click the 'Find My Altitude' button to get your current position's elevation. The system will request your browser's location permission to obtain precise latitude and longitude coordinates. We promise not to store or share your location information - all data is processed locally. After obtaining your location, the system automatically queries the elevation and geographic information for those coordinates, typically completing within seconds.

Question 3

Can I compare altitudes of multiple cities simultaneously? How does altitude comparison work?

Accepted Answer

Absolutely! You can search and select multiple cities in the 'Global Cities Database' for altitude comparison. The system provides powerful comparative analysis features including sorting by elevation in ascending or descending order, interactive chart visualization, and meter/feet unit conversion. You can also add your current location to the comparison list to intuitively understand elevation differences between locations. This feature is especially useful for travel planning, hiking route selection, and geographical research.

Question 4

What coordinate systems and search methods are supported? How accurate is the data?

Accepted Answer

Our tool supports decimal degree format for latitude and longitude coordinates. You can input coordinates directly or search by location name to get altitude information. The database covers major cities and regions worldwide with authoritative and reliable data sources. For remote areas, data accuracy may vary, but we strive to provide the most accurate elevation information possible. The system also supports continent-based city filtering for regional elevation analysis.
