The course introduces land surveying and related equipment, main sources of maps for landscape and urban areas and their use; indicates potential limits of accuracy and criteria of choice on green spaces design.
Textbooks:
• Del Gaudio - “Corso di Topografia”
• Aruta, Marescalchi “Cartografia. Lettura delle carte” - Flaccovio editore
• Capello –“La lettura delle carte topografiche e l’interpretazione dei paesaggi”
• Teacher’s handouts.
Learning Objectives
Knowledge acquired: proper use of surveying equipment and maps for those involved in green areas design and implementation
The objective is to provide students with the basic knowledge of tools and methodologies for the correct interpretation of the territory through the topography and numerical cartography.
Frequency of lectures, practice and lab:
although not mandatory, frequency is strongly recommended.
Type of Assessment
Preliminary written/practice examination; oral examination on the subjects of lectures and practice activities.
Evaluation criteria: in written tests with open questions or carrying out calculations, the unsuccessful answer and the wrong answer are considered in the same way; the oral exam takes into account: argumentative rigor, completeness, originality, language properties.
