Subject fundamentals
This course is designed for students who present a particular interest in the study of the territory relative to building and infrastructure construction, urban planning, use of natural resources and analysis of environmental phenomena. The course aims to describe the characteristics of digital mapping as an essential component of a Geographic Information System (GIS), the ideal tool for a correct representation of land for his planning and management. Particular attention is paid to the description of the photogrammetric techniques for the acquisition of the primary data.
Expected learning outcomes
Students will become familiar with digital map, database, Geographic Information System (GIS): which are their characteristics, how they are designed and produced, as you acquire the data they contain and so on. Students also learn the techniques of data acquisition that are the heart of GIS with particular regard for digital photogrammetry approch. At the end of the course, students will be able to design a GIS, define the most effective techniques for data acquisition and build a prototype of the GIS with commercial software (ArcGIS) or open source (gvSIG , QGIS ... ) .
The course stimulates students to form independent judgment to the reading of special specifications for tenders for the production of digital map to understand the content and critically analyze its effectiveness.
The conduct of exercises through working group encourages interaction with colleagues and exchange of information, forcing students to acquire properties of language and clarity.
From the point of view of learning ability, the student, at the end of the course, will be able to apply the acquired knowledge to other application cases, possibly using other commercial software, carrying out the design steps described in the course.
Prerequisites / Assumed knowledge
It requires the basics on the main terrestrial reference systems used in Italy and in the world and cartographic representations associated.
Contents
Geodetic reference systems and cartographic coordinate systems: the transformation between them, the method Verto proposed by IGM, some software for performing conversions ( Cartlab, Verto GIS , ...).
The digital map: its 3D content (planimetric and height), the nominal scale, the discretization of curved lines, coding systems, the geometric and topological structure, the problem of editing, congruencies, the make-up.
The production techniques of digital map: the first generation (the direct survey in the field using total station sand GPS receivers), second generation (photogrammetry for mapping applications, direct photogrammetry, characteristics of photogrammetric flights at different scales, stereo-plotting, remote sensing ), third generation (digitizing existing maps, the digitizer, the digital scanner, paper orientation, manual and automatic tracking of lines).
The geographic information systems: GIS definition and structure of a GIS, the organizational context, its design, history of DB , the design stages , the conceptual model diagram ( Entity/Relation), the logical model (relational DB), the physical model, types of usable data (vector, raster and alphanumeric), the management software (commercial, free, open source), some design examples of GIS , spatial DBs , addressed to the GIS objects, sharing in internet/intranet ( WebGIS ) .
The height models : definitions, standards of quality, informative content, the 3D GIS .
The special specifications for tenders for the production of digital cartography.
Delivery modes
The practical laboratories took place at LAIB make up about half of the course and are dedicated to the realization of two main themes:
- Development of practical photogrammetric process (design of flying, interior orientation, exterior orientation, restitution, editing) that leads to the production of a digital map using digital photogrammetry.
- Carrying out practical design of a GIS descriptive or management and subsequent implementation by commercial software (ArcGIS) or freeware (QGIS, GRASS, ...).
Work is carried out in a group and at the end of the exercises must be completed a special report describing which is a part of the final grade.
Texts, readings, handouts and other learning resources
The main text consists of the lecture notes provided by the lecturer and the slides presented during the lectures.
We recommend any detailed text:
- Cesare CAMBURSANO, Cartografia numerica, editrice Progetto Leonardo, Bologna.
- Karl KRAUS, ggiuseppeFotogrammetria, Vol. 1. Teoria e applicazioni – traduzione e ampliamenti di Sergio Dequal, Libreria universitaria Levrotto & Bella.
Assessment and grading criteria
The exam consists of 3 ratings:
- 2 exercises held during the workshops (the production of digital mapping by photogrammetric technique , the design of a GIS and its implementation in prototype form ) are evaluated using the 2 reports on that must be delivered at least one week before the holding of ' examination . The teacher analyzes the reports and proposed a vote of thirty ;
- The ability to use GIS tools is evaluated by a practical test inherent the GIS software used during the exercises. At the end of the test, the teacher proposes a vote of thirty.
- The theoretical aspects described throughout the course upon which the practical applications proposals is assessed by an oral exam with a score of thirty .
The final grade is a weighted average of the results of 3 ratings, considering the weight 0.4 for exercise reports, 0.3 for both practical and theoretical verifications.
