lat-lon-parser
Simple parser for latitude-longitude strings
Decision gist · record as of 2026-08-14
Yes, if you need lightweight coordinate parsing without external dependencies. The package is stable, permissively licensed, and solves a specific problem well. However, dormant maintenance (no active development) means you should verify it handles your specific coordinate formats before relying on it in production; consider it a utility library rather than an actively supported tool.AI-flagged interpretation of the facts on this page — verify before relying
Before you install
- Requires Python 3.9 or later.
- No runtime dependencies and low install friction.
- Dormant maintenance status (643 days since last release) means no active development, but the package is marked Production/Stable and has received recent version updates.

What it is and what it does
lat-lon-parser is a lightweight coordinate parsing library that converts latitude-longitude strings from various textual formats into decimal degrees. It handles formats ranging from simple decimal notation (23.43) to complex degree-minute-second strings with cardinal directions (23° 25' 48.0" North), using a straightforward pattern-matching algorithm that assumes degrees, minutes, and seconds appear in sequence with optional quadrant indicators.
The package also provides conversion functions to transform between coordinate representations—converting decimal degrees to degree-minute or degree-minute-second tuples, and formatting coordinates as strings in different notations. It requires Python 3.9 or later and has no external dependencies, making it a self-contained utility suitable for GIS applications, data processing pipelines, or any tool that needs to normalize coordinate input from multiple sources.
Use it for
- Parse user-supplied coordinate strings in web forms or APIs that accept multiple coordinate formats
- Normalize latitude-longitude data from diverse sources (GPS devices, maps, user input) into a standard decimal format
- Convert between coordinate representations for display or storage (e.g., show degrees-minutes-seconds to users, store as decimal)
- Process geographic datasets in pandas DataFrames where coordinate columns contain mixed or non-standard formats
- Build GIS tools or mapping applications that accept coordinates in human-readable degree-minute-second notation
