About

SQLite/DB

SQLite/SpatiaLite is a solution for storing geospatial data in SQLite databases. The SpatiaLite extension adds spatial data types, spatial indexing, and spatial functions to SQLite, making it a lightweight spatial database. SQLite databases are single-file structures requiring no server, ideal for embedded and mobile GIS applications.

GMT

GMT ASCII Vectors is a text-based vector data format used by Generic Mapping Tools (GMT) software. GMT is widely used in earth science research and academic paper map making. The GMT format records geographic features as text lines, each containing coordinates and optional attribute information.

Conversion trade-offs

SQLite/DB: limitations to know

  • Requires SpatiaLite extension for spatial functionality
  • Does not support concurrent multi-user writes

GMT: what you gain

  • Widely used by earth science researchers

Why convert SQLite/DB to GMT?

Converting SQLite/DB to GMT is one of the most common workflows in GIS. SQLite/DB data usually comes from desktop GIS software, government open-data portals, or data exchange with partners, while GMT is what modern tools, web maps, and platforms expect. This converter bridges the two: it reads your SQLite/DB files, keeps geometry and attributes intact, and writes clean GMT output — entirely in your browser, so your data never leaves your device.

Frequently asked questions

Are my files uploaded to a server?

No. The conversion runs entirely in your browser using WebAssembly — your files never leave your device.

Is the SQLite/DB to GMT converter free?

Yes, completely free with no sign-up and no usage limits.

Are coordinate systems preserved when converting SQLite/DB to GMT?

By default the output keeps the source coordinate system. If your SQLite/DB file uses a projected CRS (like UTM), you can search any EPSG coordinate system by keyword or code and reproject in one step. Note: output formats that require WGS84 by specification (KML, KMZ, GPX) always reproject to WGS84 automatically.

Can I convert multiple files at once?

Yes — drop several SQLite/DB files at once and each one produces its own GMT output.
