- 13. TERMINOLOGY • Spatial data (aka geospatial data or geographic information) Information about the locations and shapes of geographic features and the relationships between them, usually stored as coordinates and topology. Any data that can be mapped. • Cartography The study and practice of making maps. Combining science, aesthetics, and technique, cartography builds on the premise that reality can be modeled in ways that communicate spatial information effectively. 13
- 14. TYPES OF MAPS 14 Thematic map Designed to show a particular theme connected with a specific geographic area. Types: Choropleth, Dot, Isoline, Flow Maps, Cartograms General Map General cartography involves those maps that are constructed for a general audience and thus contain a variety of features. Example: Road map, atlas, classroom world map Orienteering map combines both general and thematic cartography http://training.fws.gov/courses/csp/csp7203/resources/Types_of_Maps_2013.pdf
- 15. TYPES OF MAPS Topographic Displays terrain: the three-dimensional quality of the surface and the identification of specific landforms. This is also known as geomorphometry. Topological map Diagram that has been simplified so that only vital information remains and unnecessary detail has been removed. These maps lack scale, and distance and direction are subject to change and variation, but the relationship between points is maintained. 15
- 16. Thematic MAPS 16 Choropleth Shaded or patterned areas in proportion to the measurement of the statistical variable displayed on the map Ex. Population density or per-capita income Isoline A map with continuous lines joining points of the same value. Ex. Temperature (isotherms), Barometric pressure (isobars), Wind speed (isotachs), and Wind direction (isogon) http://www.clearlyandsimply.com/clearly_and_simply/2009/10/choropleth-maps-with-tableau.html
- 17. TYPES OF MAPS 17 Flow maps A mix of a map and a flow chart that "show the movement of objects from one location to another". Cartogram A map in which some thematic mapping variable is substituted for land area or distance. The geometry or space of the map is distorted in order to convey the information.

- 19. MAPPING IN TABLEAU • Filled Maps & Symbol Maps (Shapes) • Customer mapping stories & examples http://www.tableau.com/stories/topic/maps • Information on data that Tableau uses for maps: http://www.tableau.com/mapdata • Tableau’s online help portal for mapping http://onlinehelp.tableau.com/current/pro/online/ windows/en-us/maps.html 19
- 20. GEOCODING Geocoding (sometimes called forward geocoding) Uses a description of a location, usually a postal address or place name, to find geographic coordinates Reverse geocoding Uses geographic coordinates to find a description of the location, most typically a postal address or place name. Geocoder A piece of software or a (web) service that implements a geocoding process. http://www.melissadata.com/ https://developers.google.com/maps/documentation/g eocoding/intro 20 • Tableau will automatically assign geographic roles to fields with common location names such as State, Country, and so on. • Tableau automatically geocodes the information in geographic roles with a latitude and longitude value. Tip: Right click and manually assign geographic roles to fields that weren’t automatically detected!

- 23. Dual AXIS 23 https://public.tableau.com/s/blog/2014/04/going-dual-axis-maps Duplicate the Latitude measure onto the rows shelf by holding CTRL. You'll now have 2 maps, one of top of the other
- 24. Dual AXIS 24 https://public.tableau.com/s/blog/2014/04/going-dual-axis-maps Don’t forget to Synchronize Axis
- 25. BACKGROUND IMAGE 25 http://kb.tableau.com/articles/knowledgebase/background-image-coordinates Maps > Background Images
- 27. DISTANCE Distance Formula 3959 * ACOS ( SIN(RADIANS([Lat])) * SIN(RADIANS([Lat2])) + COS(RADIANS([Lat])) * COS(RADIANS([Lat2])) * COS(RADIANS([Long2]) - RADIANS([Long])) ) Use 3959 for Miles and 6371 for Kilometers Don’t forget the Earth is curved! https://en.wikipedia.org/wiki/Horizon SQL: Has geography data types and built in functions (or you can create a custom function). You can calculate all the distances before sending the data to Tableau. http://kb.tableau.com/articles/knowledgebase/calculating-distance http://kb.tableau.com/articles/knowledgebase/find-zip-code- within-radius 27 Tableau v9.1 Feature Radial Selection Tool (Miles don’t seem appear on maps that are scaled at a larger distance)
- 28. 28 DATA PREP USING R
- 29. THE DATA The Problem • Points based within the United States • Points are non-relatable geographical points • Uncommon geographical roles (weather stations) • Points for multiple years 29 The Goal Average the points to a nearest county to create an average result based on the number of points within the nearest county
- 30. MY SUGGESTION FIND NEW DATA Something with Address, ZIP code, State, County, Census Group 30
- 31. MY SECOND SUGGESTION • Try and connect the points to the nearest county Tableau only recognize common spatial data points • Tableau Map Layers (census data) possible custom Data Layer Menu -> Map -> Map Layers • Popular tools ESRI/ArcGIS $$$$ + Learning Curve • R Need to find the right package, some familiarity (I do call this segment “Data Prep Using R”) 31
- 32. THANK YOU R GODS My code is based off this snippet http://stackoverflow.com/questions/8751497/latitude-longitude-coordinates-to- state-code-in-r/8751965#8751965 • Code was switched to County • Used a dataframe and export function (export to csv or write back to SQL) • Pulled the data from a datafile or a table (SQL) • Tested code on a small dataset first (Local Ohio counties) • Verified results -> expanded to the larger dataset 32
- 33. R IS A CRUEL MISTRESS Don’t forget • Update to the latest version of R (3.0.3 didn’t work, but 3.2.3 does work) Tip: Upgrade R to the latest release before coding • Import the packages/libraries: install.packages("RODBC") - ODBC connection (https://cran.r-project.org/web/packages/RODBC/RODBC.pdf) install.packages(“sp") - Spatial data (https://cran.r-project.org/web/packages/sp/sp.pdf) install.packages(“maps”) - Map data (https://cran.r-project.org/web/packages/maps/maps.pdf) install.packages(“maptools”) - Map tools (https://cran.r-project.org/web/packages/maptools/maptools.pdf) 33
- 34. Calculation • Functions for County and State 34 • Functions for County and State 9.7 Million Records < 5 Minutes (on my laptop) Parse data (SQL)
- 35. result • Data on the County level over multiple years 35 GIF (http://recordit.co/T0jsIXStRY)
