Maps are used for geoanalytics — displaying and analyzing business indicators on a map. These indicators may include population and population density, the number of commercial facilities and their profit, and other parameters that may affect the efficiency of a business.
You can use a map to display layers of different types:
- Areas A layer indicates entire areas or regions. Measure values are represented using colors or color shades. It's a good practice to add pop-up hints with area names or measures to a map.
- Points Points can be used to display individual objects like cities, stores, order pickup points, or customer addresses. Measure values can be indicated in two ways — through a point color and its size.
- Lines Lines are used to show links between objects in the area. For example, airline flights or cargo transportation routes.
- Heat map Shows the density of points on a map. It's helpful when you need to display a large number of points and their cocentration areas.
You can place no more than 5 layers with any visualization type on a map. Layers in the Map chart are called geolayers.
Geolayers visualize indicators using points or polygons on the map.
You can do the following operations with geolayers:
- Change name.
- Set the transparency level using the slider.
- Reorder the layers inside a visualization type. However, you can't change the order of visualization types (top-to-bottom: point map, polyline map, chloropleth map, and heat map).
You can purchase pre-calculated geolayers from partners in Cloud Marketplace.
You can't create maps in QL charts.
