Geospatial Analysis: Map Shapes Using Spatial Files

Lesson Objectives

At the end of this lesson, you will be able to:

• Describe the procedure for creating hexbins.
• Use a parameter to adjust the size of hexbins in a view.
• Describe how to calculate hexbins on a geographic map.

Use a spatial file to map types of geographic features that Tableau Desktop does not automatically recognize. The types of spatial files supported include point, polygon, and linestring geometries. Using the spatial-file connector, connect to spatial data to show discrete ground locations, from mountain peaks to railways stops; natural or designated areas such as lakes, farms, or census tracts; and linear features such as rivers, roads, and trails. 

Discover how to work with a spatial file. Disaggregate the shape data and connect to additional data, using a cross-database join, to augment your geographic analysis.
