Imagery may contain information that can be exploited to help accomplish an image-based task. The exploitation tools contain features to highlight areas of interest through markup, labeling, and measurement.
Mark Up tools
The mark up tools allow you to create simple graphics on top of your imagery using text and shape elements to call attention to areas of interest.
Create markup
To create markup, complete the following steps:
- Click the overflow menu in the upper right corner of the imagery exploitation canvas.
- In the Exploitation Tools list, click Mark Up.
- Choose a geometry.
- Point—Click on the map to drop a point.
- Line—Click on the map to draw a line segment. Double-click to complete the line.
- Rectangle—Click and drag on the map to draw a rectangle.
- Text label —Type text in the input box and click on the map to drop a label.
Note:
You can create markup in the Map Focus and Image Focus panels.
Once markup is added to an image, you can click individual markup to select it. You can move markup, change its shape, or delete it. To delete markup, select the markup and click the Clear drawn graphics button. If no markup is selected, all graphics will be deleted when you click Clear drawn graphics.
Measurements
Measuring ground features in imagery, called image mensuration, is an important function in many image interpretation or feature compilation applications. The measurement tools allow you to measure horizontal and vertical distances, areas, and feature locations on an image in map and image space. You can draw a line to measure length, a polygon to measure area, or click an individual feature to get measurement information.
To calculate measurements in the map focus and image focus views, complete the following steps:
- Click the overflow menu in the upper right corner of the imagery exploitation canvas.
- In the Exploitation Tools list, click Measurement
- Choose the measurements type.
Note:
The available measurement types will be based on information from the image metadata and capabilities on the image service. - From the drop down list, choose the Units you want your results to be displayed.
- Click on the image to create your measurement.
The measurement results will automatically populate based on the units selected and the underlying sensor model and information from the image service.
- Optionally, copy your results to your clipboard by clicking the copy to clipboard button.
- Click Clear Results to clear your measurement results and corresponding graphic on the image.
