GEOLOGICAL-TECHNICAL MAPPING
Academic Year 2026/2027 - Teacher: STEFANO CATALANOExpected Learning Outcomes
The course aims to develop students’ knowledge and operative skills needed to:
- Understand the methods and acquire the ability to conduct geological-technical surveys
- Understand the methods and acquire the ability to interpret and integrate surface and subsurface data for the preparation of geological profiles;
- Acquire skills in the accurate graphical representation of geological data and its archiving in GIS systems.
The course contributes to strengthening knowledge and understanding of:
- the principles of geological surveying and thematic mapping as tools for the observation, description, and representation of geological systems based on field data;
- environmental systems, georesources, and geological heritage in relation to sustainability and interactions with human activities;
- the fundamentals of advanced cartographic representation and geological modeling at various scales, and the main digital tools used for the processing, integration, and visualization of geological data
The course develops students’ ability to apply their knowledge and understanding in the following areas:
- the application of stratigraphic and structural survey and analysis techniques to reconstruct geological evolution;the use of stratigraphic, sedimentological, and structural data to reconstruct three-dimensional geological models of the subsurface and produce thematic maps;
- the integration of various types of geological data—structural, stratigraphic, petrographic, and hydrogeological—to produce interpretive models of the geological and hydrogeological framework at different spatial and temporal scales within the context of the Earth System;
- the translation of geological knowledge into operational assessments to support sustainable land management and the enhancement of georesources and geological heritage.
The final evaluation will take into account the degree of achievement in the following areas:
- autonomy in the ability to plan, based on cartographic data, complex interventions and plans in the territory, including those aimed at assessing natural hazards;
- communication skills, demonstrated through the preparation of a report detailing the activities carried out;
- the ability to independently consult databases, scientific literature, and regulatory references to enhance learning.
Course Structure
The course includes 21 hours of classroom instruction dedicated to planning fieldwork, designing a GIS database, reviewing surveying techniques to be applied for the creation of a geological-technical map, defining the survey objectives, and determining the legend to be used.
Criteria for the use and interpretation of any available subsurface data
The course is rounded out with 3 credits, for a total of 36 hours, of field surveying, involving 6 weekly field trips to the survey area (agreed upon with the students based on their prior experience).
The survey area will be appropriately selected in the vicinity of an urban area with the aim of reconstructing its geological subsurface model at a scale suitable for practical applications (> 1:10,000), integrating the original surface surveys with the interpretation of available subsurface data.

Learning Assessment
Learning Assessment Procedures
The exam consists of a dissertation on a GIS project containing:
a database of geological data collected by the student during fieldwork;
the original 1:10,000-scale geological-engineering map of the study area (generally 10 km²);
links to geological-engineering profiles and any other diagrams produced
During the discussion, the theoretical aspects applied in conducting the geological-technical surveys will be explored in depth, as well as the criteria for interpreting the subsurface data used to reconstruct the 2D geological model depicted in the geological profiles.
