{% tab title="Benefits" %}
**Contextual backdrop mapping**

The product provides contextual backdrop mapping for your applications or web pages. It contains important buildings, functional sites and greenspace.

**Vector version**

Vector data map styling is highly customisable to suit your needs; premade stylesheets are also available for Ordnance Survey’s traditional styles.

**Raster version**

OS OpenMap – Local includes a raster image option, carefully styled according to customer feedback. This is easy to load in a GIS and lets you start analysing data quicker.

**Private roads and tracks**

To help you navigate around Britain, we’re adding more names, such as those of isolated homes and farms, and roads, both public and private. This detail comes into its own in rural and suburban areas.

**Identify hotspots in data**

**Get insights for local planning**

Get greater insights into land use for local planning. OS OML doesn't just pinpoint schools, hospital and other major facilities, it maps the grounds they occupy.

**Assessing local sites of interest**

OS OML lets you easily assess local sites of interest (for example, educational facilities), highlighting their location and context within an area.

**Displaying the location of a business**

The local view of OS OML is ideal for creating a map of a street or neighbourhood to share the location of your business, complete with street and locality names to provide context.
