Oblique Viewer

The Oblique Viewer widget displays images in a native coordinate system using an image coordinate system (ICS). Oblique images are displayed in a native ICS to avoid distortion caused by projecting them in a geographic coordinate system or projected coordinate system. The Oblique Viewer widget allows you to pan in the oblique mode, pan in a single viewing angle, or switch angles to view an area of interest from different angles.

The following table lists the configurable attributes of the Oblique Viewer widget:

AttributeDescription

layerTitle

There is no default. Title of the image service layer containing oblique imagery data in the web map.

azimuthAngle

The default value is zero. The azimuth angle the widget should start in.

azimuthField

There is no default. The field in the image service that defines the sensor azimuth of an image. The azimuth field in this case is the "look towards" angle, clockwise from north. So, looking towards north is 0, east is 90, south is 180, and west is 270.

elevationField

There is no default. The field in the image service that defines the sensor elevation of an image. This can vary from 0 (horizon) to 90 (completely nadir).

rasterInfoFields

OBJECTID and Azimuth are selected by default. An array of field names to be shown in the list of rasters in the chosen direction.

showThumbnail

Boolean. The default value is true. Determines whether to show the thumbnail in the list.

autoSync

Boolean. The default value is true.. Determines whether to synchronize the main map when the oblique map is panned or zoomed.
