Mapping in Tableau is easy when you have country, city, or postcode data, but what if you want some custom shapes? Tableau 10.2 adds a new spatial connector allowing the creation of custom geocoding. Tableau Zen Master Matt Francis shows how to take a spacial shape file and add it to Tableau to create a map based on custom geospatial data
- [Narrator] Creating a map in Tableau is a great way…of analyzing your data when there's a geographic…component to that dataset.…That is where the location of something is important…in the terms of the analysis.…Now Tableau's got a very good repository of information…about geographic data.…For example, if you have countries, or states,…or area codes, and you drop those into the rows…and columns, Tableau will build the map for you.…But what if you've got data that sits outside of that?…If you've got some custom shape files…that you want to incorporate?…Now in the past, this would involve creating the polygons,…putting the information in,…and doing a lot of pre-processing outside of Tableau.…
So this is obviously a lot of work,…and also when you imported it in,…the performance of the polygons wasn't great.…In Tableau 10.2 there's a new spatial file connector,…which allows you to connect to some of the most common…shape files.…These include ASR Shapefiles, KML, Map Info tables,…and Geo JSON files.…Now these are the most common spatial file formats…
