**Highly detailed attributes**

OS VectorMap Local is full of rich, detailed mapping attributes and features that improves contextual information and in-depth analysis – especially when compared to alternative data sources.

**OS VectorMap Local can be used in a variety of formats**

Try using the dataset in colour, or with a black and white backdrop.

**Customisable**

Prebuilt colour options are available for both vector and raster formats, but vector data is fully customisable. You can design your OS VectorMap Local basemap to perfectly suit your needs. This might be to a preferred colour palette, to suit different viewing methods or to highlight features of most interest.

**Accurate and reliable real-world information**

OS VectorMap Local is generated automatically from OS Large Scale Topographic database (used for [OS MasterMap Topography Layer](https://docs.os.uk/os-downloads/products/maps-and-imagery-portfolio/broken-reference)), improving currency and consistency to give accurate and reliable real-world geographical information.

{% tab title="Use Cases" %}
The purpose of OS VectorMap Local data is to support a wide range of customer applications that utilise geographic information. These applications may include the following:

* **Real-world analysis:** Features are representations of real-world objects, including buildings, roads, railways, rivers and land areas, as well as non-topographic features, such as administrative and electoral boundaries, cartographic text and symbols, and height detail.
* **Backdrop web mapping:** Data can be chosen selectively and customised to suit a range of online user requirements.
* **Detailed building analysis and assessment:** Reduced building generalisation parameters in the product lets users gain a greater understanding of the proximity of natural and man-made risks, such other buildings or rivers with poor drainage.
* **Basic road routing:** The connected road network with additional attribution in the product enables enhanced routing capabilities and cartographic styling for users.
* **Evaluating possible sites for new amenities:** The level of detail provided in the product means that customers can use it to create shortlists for evaluating and planning new site locations without leaving the office.
