# Immersal SDK

In a nutshell, the Immersal SDK is a spatial mapping & visual positioning system. It allows you to merge digital content with the physical world by enabling devices to precisely locate themselves in the physical world.
You could think of it as an ultra accurate GPS with full six degrees of freedom (6DoF) support and realtime updates. Not only does the device know its position in the world, but also the exact orientation.

The solution is completely markerless so you don't need to print out QR codes or anything similar.It uses the environment itself as a "marker".

You can create Augmented Reality (AR) experiences and tools that are tied to real, physical locations. These next-generation AR applications allow users to interact with their environment and do things never possible before.

# The Immersal solution consists of 3 parts:

Mapping real-world locations. The maps are constructed and hosted on Immersal's Cloud Service and can be captured using a ready-made Immersal Mapper app for iOS and Android
Building applications that use these maps with the Immersal SDK
Localizing (finding the position and orientation in the map) end-user devices to show the persistent digital AR content to the end-user

# What can it do?

Immersal SDK brings immersive AR experiences and tools to large spaces.

The applications are limitless and range from AR games to ad campaigns, indoor navigation, and maintenance tools for industries — your imagination is the limit.
To get an idea of some of the possibilities, please watch a video of some of our early concept tests.

The following case study demonstrates the pipeline from capturing to editing content in a commercial application.
