SpatiaLite / SQLite to KML

SpatiaLite to KML Converter Online | GeoDataViewer

Quick answer: Convert SpatiaLite to KML online for free. Open your SpatiaLite data, inspect the map preview, and download KML output locally in your browser — no upload required. SpatiaLite extends SQLite with spatial types, indexes, and functions so a single portable database file can support GIS-style querying and editing workflows.

Before converting SpatiaLite / SQLite to KML

Prepare the input

Choose a complete SpatiaLite / SQLite dataset (.sqlite, .sqlite3, .db). Keep required sidecar files together and check the source coordinate reference system.

Know what you download

KML output is an XML geometry and attribute handoff for Google Earth. It is not an asset-complete KMZ and does not reproduce every original style or application extension.

Limits and troubleshooting
  • Converting SpatiaLite / SQLite to KML can change field types, metadata and presentation. A successful download does not prove every source element survived.
  • KML styles, tours, overlays, remote links, icon assets and folder semantics may not survive geometry conversion. Retain the original for Google Earth presentation.
  • Confirm WGS 84 longitude/latitude placement in the downloaded output. Missing source CRS cannot be inferred safely; use a desktop GIS to assign or reproject an unknown CRS.
  • Browser memory varies by device. There is no guaranteed unlimited file size; split large datasets or use a desktop GIS when memory or WASM initialization fails.

If something goes wrong

  • Empty or partial preview: confirm the source contains supported vector geometry and compare the source layers with the preview.
  • Wrong continent or distorted geometry: inspect the source CRS, axis order and a known location. Valid syntax alone does not guarantee valid placement.
  • Conversion cannot start: reload while online so processing libraries and WebAssembly can load, then retry a smaller known-good sample. File contents are still processed locally.
  • Incomplete export: compare source/output counts, geometry families and key fields. Inspect warnings and keep the original file.
Source Format Guide

What is SpatiaLite / SQLite?

SpatiaLite extends SQLite with spatial types, indexes, and functions so a single portable database file can support GIS-style querying and editing workflows.

SpatiaLite is attractive because it combines the portability of SQLite with many of the practical benefits people expect from a spatial database.

It is especially useful when a project wants SQL-based filtering, joins, and structured storage without depending on a heavier server database or a loose collection of flat files.

Common Workflows

Common use cases

  • Analyst handoff packages that need more structure than GeoJSON or CSV.
  • Field or laptop workflows that want database capabilities without running PostGIS.
  • Intermediate processing stores for ETL pipelines and local data science work.
Ecosystem

Where you will encounter it

  • Offline analysis and laptop GIS workflows.
  • ETL and data science pipelines that benefit from SQL.
  • Portable database-style project exchange.
Strengths

Why teams choose SpatiaLite / SQLite

  • Single-file SQLite packaging is easy to move and archive.
  • Spatial SQL and indexing support make it more powerful than simple flat files.
  • Good compromise between database behavior and file-based portability.
Limitations

Where SpatiaLite / SQLite gets awkward

  • Less familiar to non-GIS or spreadsheet-only users than CSV and Excel.
  • Some consumer tools and lightweight viewers do not understand spatial SQL containers directly.
  • Tile delivery and simple presentation workflows may still prefer other targets.
Conversion steps

How to convert SpatiaLite to KML online

  1. 1. Add your SpatiaLite file

    Drop the source data into the converter above. Keep any required sidecar files together when your dataset uses them.

  2. 2. Check the map preview

    Inspect the geometry and attributes before exporting so you can spot missing layers or coordinate-system issues.

  3. 3. Download KML

    Run the conversion and save the generated KML output directly from your browser. Your source file stays on your device.

File Structure

Common file extensions and sidecar files

.sqlite
Common SQLite container extension used for SpatiaLite-enabled datasets.
.sqlite3 / .db
Alternate SQLite file extensions often seen in the broader ecosystem.
spatial metadata tables
Internal SQLite tables that register geometry columns, spatial reference metadata, and indexes.
Conversion Rationale

Why convert SpatiaLite / SQLite to KML?

Teams commonly convert SpatiaLite / SQLite into KML when they need easy sharing into Earth browsers and visualization-focused tools.

  • Teams convert SpatiaLite when they need a flatter exchange artifact, a legacy delivery format, or a web-friendly output that non-database tools can open quickly.
  • They also convert into SpatiaLite when flat files need to become queryable and better organized without standing up a server database.
  • KML is a common export target for Google Earth-style review, annotation, and presentation workflows.
  • It is well suited to map storytelling and visual inspection rather than heavy analytical editing.
FAQ

Frequently asked questions about SpatiaLite / SQLite to KML

What do I need before converting SpatiaLite / SQLite to KML?

Choose a complete SpatiaLite / SQLite dataset (.sqlite, .sqlite3, .db). Keep required sidecar files together and check the source coordinate reference system.

What exactly is in the KML download?

KML output is an XML geometry and attribute handoff for Google Earth. It is not an asset-complete KMZ and does not reproduce every original style or application extension.

How large a SpatiaLite / SQLite file can I convert?

The practical limit depends on browser memory, geometry complexity and the conversion driver. Start with a small sample. There is no guaranteed unlimited size and no cloud fallback or payment tier for large files.

Are my SpatiaLite / SQLite files sent to a server?

File parsing and conversion run on your device. The page, WebAssembly and map basemaps can make network requests; choosing a file does not upload its contents. Load the required libraries before attempting offline work.
