Question 1

How to set up Martin to serve tiles from a PostGIS database?

Accepted Answer

Configure Martin by specifying the PostgreSQL connection string in a config file or via CLI arguments. It will automatically discover tables with geometry columns and expose them as tile endpoints. Refer to the documentation for examples on connection parameters and authentication.

Question 2

Martin vs Tegola: which is better for PostGIS tile serving?

Accepted Answer

Martin is written in Rust and emphasizes automatic discovery and performance, with tools like martin-cp. Tegola is Go-based and offers similar features but may differ in configuration syntax and community plugins. Choose Martin for Rust ecosystems or if you prefer its integrated tooling.

Question 3

Can Martin handle raster tiles or only vector tiles?

Accepted Answer

Martin primarily focuses on vector tiles as per the specification. While MBTiles can contain raster data, Martin's core functionality is optimized for vector tile generation and serving; check the documentation for any limitations or experimental raster support.

Question 4

How to generate an MBTiles file from a PostGIS source using Martin?

Accepted Answer

Use the martin-cp tool to generate tiles in bulk from PostGIS or other sources. Run a command specifying the source URL and output MBTiles file path, and it will efficiently create the tile archive with configurable zoom levels and bounds.

Question 5

Is Martin suitable for high-traffic production deployments?

Accepted Answer

Yes, Martin is designed for performance and heavy traffic, with Rust ensuring low latency and high throughput. However, for production, ensure adequate server resources, monitoring, and backup strategies, as dynamic tile generation can be resource-intensive.

Question 6

How to combine multiple tile sources into one endpoint with Martin?

Accepted Answer

Define composite sources in Martin's configuration file by listing multiple tile sources (e.g., PostGIS tables and PMTiles). Martin will merge them into a single endpoint, useful for layered maps or aggregating data from different origins.
