# Goals for this morning
--
+ Quickly review of different types of maps and discuss their use
--
+ Provide a survey of common mapping tools
--
+ Discuss the difference between open-source and proprietary software as it relates to GIS and mapping
--
+ Practice using an online, interactive webmapping service (CARTO) to create a simple interactive map using open data
---

# Why Do We Create Maps?
---
class:center,middle
# Types of Maps
---
# General Reference Maps
--
+ Show important physical features of an area
--
+ Include natural and man-made features
--
+ Usually meant to help aid in the navigation or discovery of locations
--
+ Usually fairly simple
--
+ Can be stylized based on the intended audience (tourists vs locals)
---
class:middle
---
# Thematic Maps
--
+ Focuses on a specific theme or subject area
--
+ Features on the map represent the phenomenon being mapped
--
+ Spatial features used for reference
