## Smart Maps Bazaar (SMB)
- In Smart Maps, **we connect data and apps**.
- Host heavy cloud-optimized data on **IPFS**.
- IPFS: InterPlanetary File System
- old name: InterPlanetary Operations (IPO)
---
### User story
Users share **hundreds of gigabytes** of cloud-optimized open geospatial data, such as imagery, point cloud, vector tiles or city models, **without a server** from anywhere with an Internet connection.
---
### Steps for data providers
1. **Create** cloud-optimized data, in such as COG, COPC, PMTiles or 3D Tiles.
2. **Share** the data from their IPFS node.
3. **Connect** their node with smb.optgeo.org node.
4. Anyone can access the data through `https://smb.optgeo.org/ipfs/${cid}`.
