# How to Import Data in Different Coordinate Systems

## **Introduction**

NavVis IVION supports capturing data in many different coordinate reference systems. These coordinate systems can be exactly expressed using their EPSG number.

## **Procedure**

When importing data into NavVis IVION, it is vital to create your Site correctly. When creating the site, two things should be observed:

1. The site Base Point must be created within a 20km radius of all Datasets which are to be imported into this site. If datasets are out with this, attempting to import these will cause an error.
2. The correct EPSG system must be chosen. As standard WGS84 is used, however if the data is captured in a different reference, this must be defined in the "Advanced Tab" of site creation. The image below shows where to search for and define the reference system.

Site refers to a complex of one or more buildings displayed in a NavVis IVION instance. For example, the Munich Airport would be one site. An instance can contain multiple sites. Each site consists of one or more datasets.

A dataset is a piece of a site, the result of a continuous recording with a NavVis mapping device or the result of an imported point cloud. Datasets can contain panoramic images and point clouds.
