- | This page describes how to use the desktop mobile mapping administration procedure “Process Point Cloud Image”. | ||
- | |||
- | The “Process Point Cloud Image” procedure allows the Orbit administrator to process a 2D ortho photo from the point cloud top view ((Process Point Cloud Image is possible for all [[180: | ||

- | **Coordinate system** \\ | ||
- | A point cloud image can be created in any projected coordinate system. Geographical coordinate systems cannot be used as output CRS. | ||
- | |||
- | **Resolution in meter** \\ | ||
- | The resolution defines the pixel resolution expressed in meters of the point cloud images. \\ | ||
- | Depending the density of your point cloud the resolution can be adjusted : | ||
- | * 1 or 2 centimeter resolution for high density point clouds | ||
- | * 5 or 10 centimeter resolution for low density point clouds | ||
- | |||
- | **Point Cloud Legend** \\ | ||
- | A legend for the point cloud image can be set. \\ | ||
- | If RGB and reflection information are available an according image can be created. An image by fix color or height is always possible. | ||
- | |||
- | Only one point cloud image can be created for each legend type : \\ | ||
- | rgb, reflection, height, fix color. \\ | ||
- | Orbit will replace an existing point cloud image when creating a new point cloud image if one already exits. | ||

- | **Result** \\ | ||

- | This usability issue is fixed in version 11.2. A workaround in version 11.1 is to switch the point cloud legend file before opening the run depending your needs. Download, copy and rename into <Orbit Run directory> | ||

- | <note tip>You can drag and drop an OLG-file on the dataset in the datasetlist in the Orbit Desktop to apply the orbit legend on the fly. The default point_cloud.olg file will not be overwritten.</ | ||
