Importing Non-Georeferenced Image Files
Non-georeferenced image files are culture files that do not contain geographical coordinates. Similar to other culture files, non-georeferenced images can either be overlaid on a map or shown on a specific time slice/section.
The images are listed on the Culture tab in Control Panel, while images imported onto a time slice only display when the time slice is turned on (see Import Images onto Map View).
- In the Control Panel, go to the Import menu.
- Click Culture.
- Select the non geo-referenced image file(s) (jpg, tiff, png) to be loaded, and click Open.
- In the Coordinate Reference System conversion window, accept the default setting, and press OK.
In the Image Properties window, the default tie points are as follows:
- The default tie point 1 is the top left pixel 0,0.
- The default tie point 2 is the bottom left pixel 0, Y.
- The default tie point 3 is the top right is pixel X, 0.
- To adjust the tie points:
- Drag the image to the desired X/Y locations; or
- Type the desired values directly in the X and Y columns or click the pencil icon to click on the exact location. Insight will update the X and Y columns based on the cursor location.
Note: For each pixel tie point, assign a valid X&Y location. Unless you know the pixel location of a specific feature within the image, it is best to use the default corner point pixels.
- To finish editing, click the “X” button at the top-right corner of the window, or press the Esc key.
Tip: Optionally, you can assign Opacity, a Vertical location, and/or set a Constraint area to the image.
