Elements and Performance Criteria

1. Identify image and ancillary data.
   • Task requirements are clarified with appropriate persons.
   • Possible sources of image data are identified to meet task requirements.
   • Constraints in using different types of image data are clarified in discussion with appropriate persons.
   • Ancillary data that can be used to assist visual interpretation of image is identified and obtained.
2. Identify and record basic landscape features.
   • Image data is visually interpreted using interpretation principles and ancillary data, and features are identified and recorded according to task and organisational requirements.
   • Interpreted results are discussed and confirmed with appropriate persons.
   • Ground control targets for photogrammetric mapping are checked to enhance understanding of image data.
   • Scale is determined according to organisational requirements.
   • Data is stored and documents are completed according to organisational requirements.

Performance Evidence

A person demonstrating competency in this unit must satisfy the requirements of the elements, performance criteria, foundation skills and range of conditions of this unit. The person must also visually identify three instances of the following from both an aerial or terrestrial photograph or image, and a satellite image:

buildings

rail lines

roads

terrain types

vegetation

water bodies.

Where images from ground penetrating radar (GPR) are required to be interpreted, the person must visually identify three of the basic landscape features listed above from:

a GPR image display, and

one of the following:

aerial photograph or image

satellite image.

While visually interpreting the above image data, the person must:

assess task requirements to clarify types of image data to be accessed and interpreted

communicate clearly with others to clarify and discuss work tasks

identify possible sources of image and ancillary data to meet task requirements

apply the principles and methods of visual image interpretation

apply ground controls to aerial photographs

calculate scale from image data

comply with organisational requirements relating to:

accessing and formatting image data

data privacy and information copyright

health and safety

conduct basic measurements relating to image data to identify scale

identify and report constraints and problems with image data

use organisational proformas to accurately record measurements and data.
