Service Description

This service is an extension of existing mapping APIs in Javascript. It serves for querying the altitude information and other topological information about places on the Earth.

The topo data is a combination of SRTM and GTOPO30, its typical horizontal resolution is about 90 meters. The data includes all continents but Antarctica.

Currently the service is in the beta stage of testing, the throughput of the shared server might be limited. For business users, we offer paid servers with dedicated capacity.
