3. •A complete GIS platform that exists on the Desktop, Server, on Mobile
devices, and in the cloud
•Powered by proven open source components
•Commercially supported to ensure quality and ease-of-use
•Designed for modern infrastructures
3
The Premiere Open Source GIS Ecosystem

4. I have lots of spatial data
Want share it with the world
What if someone doesn’t have a GIS application
And no one want to download large files in strange
formats
Geospatial Data Problem

5. Solution
Everyone has a Web Browsers
Use a Web map to make the spatial data easy to read and enjoy

6. Web maps work on everyone’s modern computer or mobile
Web maps can be embedded and styled in existed web sites
The technology of the web is moving fast, new stuff all the time
Web Maps are awesome

7. Boundless Web SDK - Software Development Tool
We are in a Beta for 2.0, we will be ready Soon!
Web SDK was built to meet a need to generate easy Web Maps
SDK 1.0 focused on Web App Builder - QGIS Plugin
SDK 2.0 is more of an SDK for developers to use
https://github.com/boundlessgeo/sdk
Boundless Web SDK
is awesome

Free and Open Source Software for Geospatial
•Open Source
•https://github.com/boundlessgeo/sdk
•Developed In Javascript ES6
•OpenLayers
•React
•Redux
•Webpack

9. Make Openlayers Quick and Easy
General Purpose Software Development Kit for web mapping
SDK is an engine to produce a web map from an Mapbox Style
Mapbox Style + Web SDK = Web Map
Goals of Boundless Web SDK

Web SDK

23. Free and Open Source Software for Geospatial
Mapbox Style
Mapbox Style Specification
JSON document that defines the the visual
appearance of the map

24. Free and Open Source Software for Geospatial
Mapbox Style

25. Free and Open Source Software for Geospatial
Redux State
Predictable state container for javascript
Great development experience with live code editing
and time traveling debugging
Defining State of app with a basic JSON object, and
every change to the state produces a new JSON state

26. Free and Open Source Software for Geospatial
Redux State

27. Free and Open Source Software for Geospatial
Redux State

28. Free and Open Source Software for Geospatial
React
● Facebook developed
● Uses a shadow DOM
● React Component tracks a Redux state
● Only Component updates when state updates
● React components allow splitting the UI into
independent reusable pieces and each piece lives
in isolation.

29. Free and Open Source Software for Geospatial
React
● Facebook developed
● Uses a shadow DOM to see if a component has
changed and only rerenders the part of the page
that changed
● React Component tracks a Redux state, and
Component only updates when state updates.
● React components allow splitting the UI into
independent reusable pieces and each piece lives
in isolation.
● Uses ‘Props’ to pass data in Component
