lat-lon-parser

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

Worth the install?

AI-flagged interpretation of the facts on this page — verify before relying

Parses latitude-longitude coordinate strings in multiple formats (decimal degrees, degrees-minutes, degrees-minutes-seconds) and converts between them.

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.

Install

lat-lon-parser on PyPI

pip install lat-lon-parser

uv add lat-lon-parser

poetry add lat-lon-parser

Installing lat-lon-parser

Before you install

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.

License in practice

CC0 1.0 Universal places the code in the public domain with no restrictions on use, modification, or redistribution.

Quickstart

pip install lat-lon-parser

from lat_lon_parser import parse

result = parse("45° 12.6' W")
print(result)  # -45.21

Requires Python 3.9 or later.

Verify before relying

• Whether the package handles edge cases like coordinates spanning the International Date Line or poles
• Performance characteristics when parsing very large coordinate datasets
• Whether format detection is truly robust across all claimed format combinations
