Interest

Using internet to build rich valuable collections of knowledge & product

Flexible

Easy

Homogenous systems and single vendor strategies can be convenient BUT comes with trade-off. Lack of flexibility for fast adoption

GIS

Don Cooke, early digital mapping pioneer about the explosion in mapping technology. His comment: “After 20 years, it’s nice to be an overnight sensation”.​​

Companies are using maps not just as nice features but to drive revenue as core components of their offering. Maps are no longer just a good way to visualize content, they are core to competitive advantage.

Companies are thinking more creatively about how to combine location with outside content and internal business data to differentiate products

Raster

  • Image format (png, jpg)
  • Styled before loading
  • Specific zoom levels

Map Tiles

Vector Tiles & Web Mapping

Raster Tiles

  • Don't Scale
  • Hard to change
  • Just Pictures, not data

Vector Tiles

Google Protocol Buffers

language-neutral, platform-neutral extensible mechanism for encoding structred data"

Similar to xml except smaller, faster and simpler - "FAT FREE XML"

.pbf  or .mvt (mapbox vector tile)

Vector Tiles

  • Packet of Binary format geographic data
  • Clipped to the boundaries of each tile
  • Format for Easy to Store
  • Format for Distribution at Scale

Vector Tiles

  • Very Compressed data

Vector Tiles can deliver the minimum amount of data your software needs with speed at scale with a low cost (Mapbox Spec v. 2)
