# 9. Inspect Thermal Images

Thermal images obtained by a drone can be analyzed by using Picstork. These thermal images are uploaded as an imageset while creating a task.

The user may perform manual annotations on these images by using various tools provided by PicStork as follows:

* **Point Annotations:** Point annotations are used to annotate a point on the map as shown in the following image.

* **Line Annotation:** This tool is used to cover the points on a selected line as shown in the following image.

The report generated by PicStork for thermal images contains minimum, maximum and average temperatures for line and rectangle annotations whereas, temperature values will be displayed for point annotations.
