Hexagonal geo-coding system / Original mapping project

GeoHex/ GEOHEX devide whole target area into honeycomb geometry regions.

Instead of the "Red-Pin", hexagonal geocoding system makes your world so cool.

It's honeycomb geometry shape matches for geogames’ world view, with protection for individual location privacy.

It's coordinate system makes it easy to search around, calculate distance, save data strage with short code, and makes progress in search performance.

What's new:

  • The latest version of GeoHex is "V3.2".

  • core library: http://geohex.net/src/script/hex_v3.2_core.js

  • test case (http://geohex.net/testcase/v3.2.html)

    • rect search library: http://geohex.net/src/script/getXYListByRect.js

method --> getXYListByRect(sw.lat(), sw.lng(), ne.lat(), ne.lng(), level , buffer);

response --> list[n]={"x":a, "y":b}

Feature:

    • Geo-spacial Searches

      • You can search easily within flexible levels of zone size.

    • Privacy Protection

      • GeoHex allows for different levels of precision; so, you can protect your privacy when sharing your location.

    • Easy Distance Calculation

      • Each zone is the same distance from any of its neighbors within the same level.

      • Therefore, it is easy to calculate steps between zones.

    • Smaller Data Footprint

      • One GeoHex zone ID uses from two to 17 bytes--more for smaller zones.

    • Single-query Searching

      • GeoHex is very compatible with cloud-based key-value stores.

    • Similarity to Video Game Worlds

      • Maps with GeoHex look like game worlds. Cool!
