TEXTBOOK

• Return the Workbook!
• Let's just kick the textbook to the curb and focus on online content like Khan Academy and Axis Map Guide

Anything else?

• Apparently there are issues...

GIS Applications

The Basics

Internets: how do they work?

Server Side \ Back End

• Hosts data and services *among many other things
• You can request things from it like

  'give me the closest address to this point'

• #SaaS platforms take care of this for you
  • ArcGIS Online
  • Mapbox
  • Carto

Server Side \ Back End

REST

Let's just say this is How you talk to a server. It is the best way we have, so far, to provide seamless interoperability on the web.
Everything has a URL!

Server Side \ Back End

Map Service Types

Some are open and some are vendor specific
• Web Map Service
• Web Feature Service
• Feature Service (esri)
• Map Service (esri)
• Vector Tiles (mapbox)

Server Side \ Back End

Map Services

Rather than distribute datasets, make them available via a service.
• Authoritative data can be maintained by one entity and not independently for every user
• which leads to outdated and sometimes irelevant data
• Simpler for people to use if you:
• use a platform that supports them
• are a developer (like you)

Server Side \ Back End

Map Services Examples

The National Map

And the services behind that map

Client Side \ Front End

Uses these services via REST...

The head and the tail *textbook 1.4.3

Good analogy where Google is the head and custom applications are the tail

In between, the Body I guess, are 'opportunities' for businesses like agol, mapbox, carto, etc.

The Body

The Tail: Custom Applications

Lots of opinions but for our purpose:
• a script does a task or series of tasks
  • narrowly focused
  • no interface
• an application
  • performs tasks but also workflows and processes
  • has an interface and is interactive

Understand when you can and cannot use existing platforms

Know how to do the same thing on different platforms and, more importantly, what one platform might do (or do better) than another

Understand when you can and cannot use existing platforms

Work flow and processes may not be supported on existing mapping platforms
e.g. Metro Denver Locate Request
http://locate.metrowastewater.com/

All the Web Frameworks

For custom development

Choosing one is completely overwhelming. Learn one or two and use them. They'll be out dated next year anyway.

Web Mapping Libraries (#APIs)
• *notice all of our platforms have their own custom app libraries
• arcgis js
• esri-leaflet js
• leaflet js
• mapbox js
• carto js
