Overview and Basic Navigation

Skycatch Data Hub is an application for viewing and analysis of 3D data collected by drones and other sensing equipment.

View imagery, perform measurements and analytics such as Point Picking, Line Measurements, Volume Measurements, Cut and Fill Analyses, and more.

The basic application layout is simple, with three main areas for viewing and interacting with your data:

  1. Left panel: contains controls for changing site, changing the dataset within the site, changing the visibility of the imagery layers in the dataset, and viewing and creating analytics. More items will be added in future versions
  2. Bottom drawer: when working on an analytic, a sliding drawer is displayed at the bottom of the screen to display the non-map information, such as volume calculation results. Here is an example of the bottom drawer in use with a Point Picking analytic.
  3. 3D map panel: all imagery and graphics are displayed here. 

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