New mission

New mission

New mission command opens the dialog for defining a new mission. A mission definition contains descriptive information, a scale factor, output directories for storing specific types of files during the TerraPhoto workflow, and camera definitions. A mission definition is stored into a file with the extension .MIS.

The output directories are used by TerraPhoto to store specific file types:

Temporary files - files for internal use in TerraPhoto processing. This includes thumbnails, shadow maps, and depth maps.

Rectified images - image files produced by the Rectify images command.

Ortho mosaic - image files produced by the Rectify mosaic command.

A mission may include several cameras. For each camera, a camera calibration file is required. See Define Camera tool for more information. Further, the camera definition determines the format and storage folder(s) of the raw images, the method of deducing unique image numbers from the raw image file names, and a positional accuracy attribute for images of this camera.

To create a mission definition:

1. Select New mission command from the Mission pulldown menu.

This opens the Mission dialog:

mission

2. Select the Platform of your system: Airborne or Mobile.

3. (Optional) Fill in descriptive information into the fields in the Description group.

4. Select a coordinate system in the Scale from list from which to use the Scale factor. Alternatively, define a Scale factor value manually.

5. Define a directory for storing Temporary files. Use the Browse button to select a folder from the hard disk.

6. Define a directory for storing Rectified images. Use the Browse button to select a folder from the hard disk.

7. Define a directory for storing Ortho mosaic files. Use the Browse button to select a folder from the hard disk.

8. Click Add to specify camera(s) used in the mission.

This opens the Mission camera dialog:

mission_camera

9. Define settings for the camera.

Repeat steps 8 and 9 if multiple cameras are used in the mission. Use the Copy and Edit buttons in order to speed up the definition of multiple cameras.

10. Click OK to close the Mission camera dialog.

11. Click OK to close the Mission dialog.

12. Select Save mission As command from the Mission pulldown menu to save the mission definition into a file.

SETTING

EFFECT

Name

Descriptive name for the camera.

Camera file

Location and name of the camera calibration file.

Default altitude

Default flight altitude above the ground. This enables the software to apply a projection scale correction also without a ground model.

Positions

Relative positional accuracy of images from this camera. This setting has an effect if multiple cameras are used. The application tries to modify less accurate image positions more in adjustment routines.

Numbering

Rule for how to extract a unique image number from the raw image file name:

Last number in file name - last sequence of digits.

Last two numbers - last two sequences of digits.

Last three numbers - last three sequences of digits.

Last four numbers - last four sequences of digits.

Line + image number - combination of the second-last numerical sequence (line number) and the last numerical sequence of maximum 3 digits (image number).

Last letter + number - last letter and a number.

Last number + letter + number - the last number and letter in file name and a number.

Eagle Eye numbering - system-specific numbering method.

Mitsubishi numbering - system-specific numbering method.

First number - first sequence of digits.

First two numbers - first two sequences of digits.

First three numbers - first three sequences of digits.

First four numbers - first four sequences of digits.

Format

Raster format of the raw images. The image list does not have to specify the default extension as part of the image names.

Channels

Number of channels in the raw images. If the number is bigger than 3, the RGB fields become available. Select a channel number that is displayed in place of TerraPhoto’s red, green, and blue channel. This is only active if Format is set to TIFF n*8 bit or TIFF n*16 bit.

Favor coloring points

If on, the Classes field defines point classes that are colored preferably from images of this camera. This has an effect for extracting color from images to laser points in TerraScan.

_select_classes

Opens the Select classes dialog which contains the list of active classes in TerraScan. You can select multiple source classes from the list that are then used in the Classes field.

Rotate image for viewing

If on, images with portrait format (height > width) are rotated for on-screen display. Effects the display of images in the Active full view in Tie point mode and in the Define color corrections dialog.

Image directories

Directories that store the raw images.
