Grid Point Code (GPC)

Overview

Grid Point Code (GPC) is a global geocoding system that provides a unique, lossless, and compact alphanumeric code for any geographic location (home, office, or other places). It enables precise identification and offline conversion between geographic coordinates and codes.

Features

  • Unique Global Identification: Every location receives a unique code.
  • Lossless Encoding & Decoding: Convert between latitude/longitude and GPC without loss of precision (up to 5 decimal places).
  • Offline Conversion: No network required for encoding or decoding.
  • Easy-to-Read Format: Codes are formatted as #xxxx-xxxx-xxx for clarity.
  • Proximity Awareness: Similar codes represent nearby locations.
  • Open Source: Freely available for use and modification.

How It Works

  • Encoding: Converts latitude and longitude into a unique 11-character code using a custom base-27 alphabet.
  • Decoding: Recovers the original coordinates from a GPC.
  • Validation: Ensures input coordinates and codes are within valid ranges.
  • Formatting: Provides formatted and unformatted code representations.

Usage

Encoding Coordinates

using Ca.Pranavpatel.Algo.GridPointCode;

// Encode latitude and longitude to GPC
string gpc = GPC.Encode(43.65000, -79.38000); // Toronto
// Output: #FN5G-CDKL-HDC

Decoding a GPC

using Ca.Pranavpatel.Algo.GridPointCode;

// Decode GPC to latitude and longitude
(double lat, double lng) = GPC.Decode("#FN5G-CDKL-HDC");

Validation

(bool isValid, string message) = GPC.IsValid("#FN5G-CDKL-HDC");

Format

  • Code Structure: #xxxx-xxxx-xxx (11 alphanumeric characters)
  • Alphabet: Uses base-27 characters: CDFGHJKLMNPRTVWXY0123456789
  • Precision: Up to 5 decimal places for coordinates
