Query the Atlas with SQL

The SQL query page lets you ask questions of your atlas's data — counts, lengths, lists — without downloading anything.

1. Open the SQL query page from the console's Maps list.
2. The Available Tables list shows each layer you can query.
3. Either:
4. type a question in plain English under Generate SQL from natural language (e.g. How many roads are there by street type?) and click Generate SQL, or
5. write SQL yourself in the query box.
6. Click Execute Query. Results appear below.

Queries only read data — they can't change your atlas.
