This presentation goes over the most important features of GeoServer in order to give the reader an intro about what is good and what is super-good about GeoServer! The current version reflects the presentation given at FOSS4G 2017 in Boston.

1. GeoServer Feature
FRENZY

2. Why this Talk?
● State of GeoServer talks hit what is New!
● This talk hits what is good!
● 25 min talk
○ Thirty seconds a feature!

3. So what is good?
● Crowdsource the value of GeoServer:
○ Q: What makes GeoServer great for you?
○ Q: What feature do you always enable?
○ Q: Is there an extension which made a project possible for you or a customer?
○ Q: What surprised you when you first installed GeoServer?
○ Q: What community module do you wish was part of GeoServer?

How easy it was to get maps in my
openlayers application.
Mark Ismail

How easy it was to install and
configure with GUI without a need
to write mysterious configuration
files by hand, and that after the
clickety-click installation everything
just worked.
Jukka Rahkonen
How easy it was to connect to PostGIS.
Ben Caradoc-Davies
How easy it was to
setup a geoserver
and display your
data, even without
any gis-specific
knowledge.

29. Everybody loves curves
● Read curved geometries from Oracle, paint them, GML output them, linearize
everywhere else

30. Rendering Speed
Your maps .. faster
rendering speed
Phil Scadden

31. Spatial Index
● Key to rendering speed when zoomed in
○ Quickly sort through data using a bounding box
○ Remaining features filtered according to SLD

32. Geometry Simplification
● Zoomed out so far that several
points are located in the same pixel?
○ GeoServer will simplify as it reads from disk/database

33. Smart reprojection
● Simplify before reproject
● Linearize transformation math as needed

34. Pre Generalized DataStore
● Switch between:
○ original data when zoomed in
○ simplified data when zoomed out
● This is transparent to WMS and Rendering
○ No need to add SLD rules based on scale
○ Vast improvement when zoomed out!
● For more information
○ Pregeneralized Plugin (GeoTools User Guide)

35. Switch tables based on distance
