Maps

CDP Data Visualization enables you to create Map visuals.

A geomap of a country, continent, or region superimposes measurement values onto a geographic map.

CDP Data Visualization has two basic geomap representation options:

  • A filled or choropleth map (Greek χώρο for area or region and πλήθος for multitude) shows geographical areas that are shaded in proportion to the value of the measurement that is displayed on the map.
  • A geomap with symbols or marks, such as bubbles, superimposes these symbols onto a geographical map. By default, the area of the marks corresponds to the relative size of the measurement.

Arcadia supports the following geographical specifications by automatically recognizing them as qualified GEO dimensions inside the dataset:

  • country
  • state or province for United States and Canada, respectively
  • county, for United States only
  • zipcode or postal code for United States and Canada, respectively
  • longitude and latitude
  • DMA, for Nielsen Designated Market Area Regions, in United States

If the relevant field in your dataset is not named correctly, be sure to adjust it using the Change Type Geo Option, described in Change type. Note also that you must use Geo Type fields when limiting the Drill Into options; see Likmiting drill into options.

To build the two types of map visuals with specified geographical units, follow the instructions for each option:

  • Geographic unit: country, type: choropleth
  • Geographic unit: country, type: symbol
  • Geographic unit: state, type: choropleth
  • Geographic unit: state, type: symbol
  • Geographic unit: county, type: choropleth
  • Geographic unit: county, type: symbol
  • Geographic unit: zipcode, type: symbol
  • Geographic unit: latitude/longitude, type: symbol
  • Geographic unit: dma, type: choropleth

Additionally, see the description on how to build a Trellised map.
