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.
ASCII Grid (also AAIGrid) is a plain-text raster format by ESRI. The file header contains geographic metadata (cols, rows, origin, cell size, NoData), and the body stores each cell value as a space-separated numeric matrix. Highly readable, often used for teaching and small-scale data exchange.
Converting SQLite/DB to ASCII Grid 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 ASCII Grid 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 ASCII Grid output — entirely in your browser, so your data never leaves your device.
No. The conversion runs entirely in your browser using WebAssembly — your files never leave your device.
Yes, completely free with no sign-up and no usage limits.
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.
Yes — drop several SQLite/DB files at once and each one produces its own ASCII Grid output.
Upload your SQLite/DB file — drag and drop it onto the page, or browse from your device. You can add several files at once for batch conversion.
The conversion runs automatically in your browser. No upload, no server — your data stays on your device the entire time.
Download the ASCII Grid file. Each input produces its own output, ready to use in your GIS, web map, or archive.
