# Over Platform

The Over Platform is based on 3 main layers:

## OVRLand Ownership Layer

OVR divided the world in 300 Sqm hexagonal Spatial Domains, mapped 1- to-1 to actual geographic locations. Just as for WebDomains, ownership of OVRLands, based on NFT standard, grants control on AR experiences in the defined geo-location

## OVRLand Mapping Layer

Land mapping allows for precise localization of AR assets to geographic locations creating a bridge between the physical and virtual world. Over Mapping is a community-driven activity called map2earn. OVRLand mappers will generate NFTs representing OVRMaps of OVRLands, such OVRMaps will be valuable digital assets freely exchangeable in the market

## Over **SDK**

Thanks to the SDK, builders will be able to use an expressive tool to connect 3D assets, experiences, and play-to-earn games to the spatial domains defined by OVRLands and mapped with Over Land Scanning. There are 2 versions of the publishing software: a no-coder web-builder and a more expressive Unity Plugin

The Over ecosystem is made up of:

* Over Community
* OVRLands
* Marketplace
* OVRLands: Buy, Sell, Rent
* Over Experience: Buy and Sell
* Over Adv: Buy and Sell
