====== View and Use Oblique data ======

This page gives an overview on the tools and functions to use oblique resources in Orbit desktop products. 

===== Open a Project =====

Use the "Open Project" procedure to load the desired imported oblique resources : 
  * [[111:oblique_mapping:desktop:core:manage:project|]]

Projects can be available to all users but permissions must be granted by the Orbit administrator. \\
Don't worry if you are using Orbit standalone products, you are an administrator. When using Orbit Client-Server all users have a well defined role / level of use. 
===== Open View from Map 2D =====

When an Oblique Project is open, the oblique views will always follow the center of the [[111:orbitgis:map:index|Map 2D]]. \\
If the center of the map contains oblique images, they will be opened in each oblique view. \\
The view angles of the oblique images are displayed as a {{:oblique_mapping:desktop:core:use:view_angles.png?nolink|}} on the Map. \\
Panning on the map will refresh the oblique views of every viewing direction.


===== Navigate in Oblique Views =====

The pan function (hand) is by default active in each oblique view. \\ 
How to navigate on the Oblique views in combination with the 2D Map can be read here:

  * [[111:oblique_mapping:desktop:core:use:view_oblique|]]
===== Oblique Toolbar and Sidebar =====

Viewing and using oblique data requires lots of tools and functions to operate fast and easy. \\
Each oblique view has a toolbar (always visible). \\
The oblique sidebar can be opened via the extensions button.

A complete overview of all buttons and icons can be read here : 
  * [[111:oblique_mapping:desktop:core:use:toolbar|]]
  * [[111:oblique_mapping:desktop:core:use:sidebar|]]


===== Measurements =====

Orbit offers lots of measure functions based on DTM or using triangulation. \\
All information about the the different measure functions and how to measure using DTM or via triangulation can be reviewed here : 
  * [[111:oblique_mapping:desktop:core:use:measure|]]
  * [[111:oblique_mapping:desktop:core:use:measure_dtm|]]
  * [[111:oblique_mapping:desktop:core:use:measure_triangulation|]]

===== Vectover Overlays =====

Any supported vector resources (2D or 3D) can be overlayed on the images. \\
When displaying vector resources in the Oblique tab special attention is required to the dataset CRS and structure definition : 
  * [[111:oblique_mapping:desktop:core:use:overlay_vector|]]
