DataHub is a web-based application designed for the viewing and analysis of 3 - Dimensional data collected by drones and other remote sensing equipment.

In DataHub, users can view imagery, and perform measurements and analytics such as Point Picking, Line Measurements, Volume Measurements, Cut and Fill Analyses, and more.

The basic application layout is simple. There are three main areas for viewing and data interaction. 

1. Left panel: contains controls for changing sites, changing the dataset within a site, changing the visibility of the imagery layers in the dataset, viewing and creating analytics, Reports, and Project Management.

2. Bottom drawer: when working on an analytic, a sliding drawer is displayed at the bottom of the screen to display non-map information like volume calculation results and analytic - related information. 

3. 3D map panel: displays all imagery and graphics.

The following sections of this user guide explain how to use the features of DataHub.

   • Choose one and select Submit. The base map tiles will update the selection
3. Quality

• • Adjust the render quality lower if you are on a less powerful PC. It won’t noticeably decrease the image quality, and it will help keep things faster and more stable in your browser. Set higher for more powerful PCs.
