 > The Position class has a static helper function for importing coordinates that are in `latitude, longitude` format. The [atlas.data.Position.fromLatLng] function can often be replace the `new Microsoft.Maps.Location` function in Bing Maps code.
 
 * Rather than specifying styling information on each shape that is added to the map, Azure Maps separates styles from the data. Data is stored in data sources and is connected to rendering layers that Azure Maps code uses to render the data. This approach provides enhanced performance benefit. Many layers support data-driven styling, done by adding business logic to layer style options that change how individual shapes are rendered within a layer depending on its properties.
-* Azure Maps provides spatial math functions in the `atlas.math` namespace that differ from Bing Maps spatial math functions. The primary difference is that Azure Maps don’t provide built-in functions for binary operations such as `union` and `intersection`. However, Azure Maps is based on the open GeoJSON standard and there are open-source libraries available. One popular option that works well with Azure Maps and provides spatial math capabilities is [turf js].
