Overview

GeoPacks are designed to work with your data without having to be incorporated and stored into your source database. Packs provide three types of data:

  1. Geographical Labels
  2. Geographical Fields (Points, and sometimes Polygons)
  3. Demographic Metrics

GeoPacks are structured to have one or more levels of geographical data. When there are multiple levels, the data will be structured in a logical hierarchy. Each level of the hierarchy will contain Geographical Labels of different formats and a Geographical Field containing a Point (and sometimes a Polygon). The pack may also have Demographic Metrics, which will be associated with the lowest level of the hierarchy which are automatically aggregated up depending on which hierarchy level you are using at the time.

 

 

See GeoPack Setup for more information.

 

Geographical Labels

In order to identify the various levels of data in the pack, and link the pack to your own data, Geographical Labels are included and displayed in multiple formats.

If we look at a simplified version of the Australian Postcode GeoPack it contains the following three level hierarchy:

  1. State
  2. LGA (Local Government Area)
  3. Postcode

Some levels of this hierarchy may have different ways to identify the geography. For example, the State level can be identified by its full name, or using a three letter code. In this case, there are multiple Geographical Labels for the State field; State Label and State Code. An example of possible label fields for this pack would be:

State Label

State Code

LGA Code

LGA Label

Postcode

Victoria

VIC

LGA23430

Kingston

3195

Victoria

VIC

LGA23430

Kingston

3196

Victoria

VIC

LGA25900

Port Phillip

3205

These label fields are used to link the pack data to your source data, and as such you must select the label that matches the formatting in your source database. For example, if you're linking on State field and your data is stored as VIC, you would link on the State Code field. If your data is stored as Victoria, you would link on the State Label field.

See GeoPack Use for more information.

Geographical Fields

Once a pack is linked, using Geographical Label fields, the Geographical Fields become available for reporting use. Each level of the pack hierarchy contains one Geographical Field. This field contains a centroid Point, and may also contain Polygons, depending on the pack design. The Geographical Field can be selected by a user and added to a map, and depending on the map type, Yellowfin will choose to use either the Point OR Polygon (where available).

See GeoPack Use for more information.

Demographic Metrics

Finally, the packs also contain Demographic Metrics. These are fields that explore various values associated with census demographics available in the geographic area.

If we look at the same simplified Australian Postcode GeoPack as above, it contains various different fields of census information. Most packs contain many demographic fields, but this simplified example contains two; Total Population and Median Age:

Postcode

Total Population

Median Age

3195

34102

39

3196

23590

39

3205

9317

37

The Demographic Metrics are designed to provide additional levels of context to your mapping, providing you with the ability to compare your data with census information for richer analysis.
