What do the map marker balloons / clusters represent?
Active Places Power displays point based data for sport facility locations on the interactive map using balloon shaped map markers.
To display map markers either run a search or report and swtich to the map tab to view results via a map interface. Alternatively run a Map Search. For all map interfaces the Map Tools tab (displayed on the left side of the map) has two sections. Use Map Search to navigate the map or Map Layers to add and remove map data layers including, individual faciliity types.
Due to the potential to represent a large number of facilities geographically on a map, a visual representation technique known as clustering is used.
Clustering reduces the number of map markers displayed on the map by grouping those in close proximity to each other in an aggregate form. Each map marker cluster contains a summary count of the number of facilities set to display.
Clustered map marker balloons have four sizes:
• Small – no count represents a single count
• Small – with count represents between 2 to 9
• Medium – with count represent between 10 to 99
• Large – with count represents between 100 to 999
Zooming in to a more detailed large scale map will result in the dispersion of markers into individual marker locations. The opposite is also true that zooming out to a small scale map will result in markers grouping together.
Map markers that continue to display a count value at large map scales will represent sites with more than 2 facilities.
It should be noted that a cluster map marker is generally located at the geographic centre for those dispersed individual locations grouped within the cluster.
Only when the cluster represents a collection of facilities at a single site or the cluster representation is turned off will the map markers represent the exact geographic location of a site with multiple facilities.
