Hexagon-Based Geographical Partitioning

Hexagon-Based_Geographical_Partitioning

Concept Overview​

  • World Segmentation: The world is divided into approximately 98 million hexagonal cells.
  • Hexagon Dimensions: Each hexagon covers an area of roughly 5 km², with a diameter of about 2 km.
  • Origin Point: The hexagonal grid originates in Berlin, Germany, serving as the anchor point for this global grid system.

Technical Details​

  • H3 Geospatial Indexing: Utilizes the H3 Geospatial Indexing Framework, as detailed in H3Geo's documentation.
  • Resolution Choice: Moonchain has selected 'Resolution 7' for this grid, balancing granularity and computational efficiency.
  • Balance of Detail and Efficiency: The resolution choice balances the detail of geospatial data and processing efficiency.

Privacy Considerations​

Key Feature​

  • Privacy through Hexagons: Enhances privacy through hexagon-based geolocation.
  • Hexagon ID Sharing: Users share only their hexagon ID, not precise coordinates.

Privacy Mechanism​

  • Location Ambiguity: By sharing just a hexagon ID, an individual's exact location remains ambiguous within a 5 km² area.
  • Reduced Tracking Risk: This system significantly reduces the risk of location tracking and personal data exposure.

Web3 Integration​

Core Concept​

  • Web3 Native Design: The system is inherently Web3-oriented, integrating seamlessly with decentralized technologies.
  • Unique Hexagon Identification: Hexagons can be uniquely identified and interacted with using Moonchain domain names (e.g., berlin.mxc).

Applications​

  • Infrastructure for DApps: Provides a robust infrastructure for Decentralized Applications (DApps) focusing on geolocation-based services.
  • Innovative Applications: Enables innovative applications such as secure tracking systems and decentralized Point of Interest (DePIN) inscriptions.

ES6 usage:

import { latLngToCell } from "h3-js";

CommonJS usage:

const h3 = require("h3-js");

Pre-bundled script (library is available as an h3 global):

<script src="https://unpkg.com/h3-js"></script>

Core Functions​

// Convert a lat/lng point to a hexagon index at resolution 7
const h3Index = h3.latLngToCell(37.3615593, -122.0553238, 7);
// -> '87283472bffffff'

// Get the center of the hexagon
const hexCenterCoordinates = h3.cellToLatLng(h3Index);
// -> [37.35171820183272, -122.05032565263946]

// Get the vertices of the hexagon
const hexBoundary = h3.cellToBoundary(h3Index);
// -> [ [37.341099093235684, -122.04156135164334 ], ...]

Naming a Hexagon​

Hexagons in the Moonchain ecosystem can be indexed and named using the Moonchain Naming System (MNS). This allows for easy identification and interaction with specific hexagons. For more details, refer to the [Hexagon Naming Tutorial].

DePINscriptions​

Hexagons are integral to the DePINscriptions system, enabling national pride for each country and region to trade their geographical inscriptions. This system allows regions to represent and trade their unique geographical inscriptions, fostering a sense of national pride.
