General information on the Unit
Contact hours: 90 (40 classroom, 50 practicals)
Personal work hours: 135
Venue: Mediterranean Agronomic Institute of Zaragoza
- Developed during the first academic year of the Master. This Unit acts as a support for the different learning stages composing Unit 8. Thus, the subjects are programmed throughout the course as required by the optimum development of Unit 8. The topic of cartographic analysis is developed at the beginning of the first semester; the topic of geographic information systems is developed throughout all the first semester; the topic of socioeconomic statistic analysis is developed at the beginning of the second semester, and the topic of remote sensing in the middle of the second semester.
- The assessment of this Unit is carried out in four written exams corresponding to each of the subjects. The exam on cartographic analysis takes place on the same day as the exam for Unit 1, and is complemented by the global assessment of the practicals (1) and (2). The exam on geographic information systems is done separately at the end of the first semester and is complemented by the global assessment of the practicals. The exam on socioeconomic statistic analysis is carried out in the second semester, on the same day as the exam for Unit 5 and is complemented by the global assessment of the group work. The exam on remote sensing takes place in the second semester, on the same day as the last exam for Unit 7.

Presentation of the Unit and context within the syllabus
This Unit provides knowledge and skills on the utilization of the main tools used in socioeconomic and spatial analysis of a territory: cartographic analysis, geographic information systems and digital database management, remote sensing and its application to natural resource management, and the analysis of socioeconomic statistical data.

Learning activity 1: Lectures
Percentage of contact: 26%
Learning activity 2: Practical work on:
- (1) access to servers, cartography viewers and compilation of an inventory of the cartographic information available for a specific municipality.
- (2) design, elaboration and layout of an environmental units map.
- (3) analysis of basic and thematic cartography: interpretation of topographic and geologic maps, scale and slope exercises, calculation of geographic coordinates and UTM, elaboration of topographic profiles, interpretation of geological cross-sections, interpretation of geomorphological maps, use and handling of aerial and stereoscopic images, definition of homogeneous units and environmental characterization of such units.
Students carry out the practicals working individually.
Geographic information systems
- (4) introduction to the software used
- (5) raster image georeferencing and digitalization and creation of a topology of geographic elements: lines, dots and polygons
- (6) import/export, raster/vector conversion
- (7) digital land models (DLM): slopes, orientations, viewsheds
- (8) interpolation of the temperatures in one area through a mixed method, including a second-degree trend surface, a digital elevation model and a residual interpolation of splines in tension
Students carry out the practicals working in pairs, but they must present the result reports individually.
- (9) understanding of an image, visualization of bands and channels of Landsat-TM images, image browsing and identification of a pixel's digital value, generation of a histogram.
- (10) contrast improvement of single-band images, interpretation of the thermal channel of a thematic map, construction of colour composites, generation of real and pseudo colour RGB image composites, interpretation of the different colours in the composites.
- (11) calculation of the normalized differential vegetation index (NDVI), interpretation of an NDVI image, comparison of images from different sensors and assessment of the appropriateness of each sensor for each application.
- (12) understanding how positioning errors can occur in spatial data and combination of satellite images with other data to improve their utility.
- (13) visual analysis of ERS-2 SAR images identifying different features and scattering mechanisms, appreciation of foreshortening and layover on SAR images, speckle identification and filter-removal, creation of a difference image of the co-registered speckle filtered images, and creation of an RGB of the two images and their differences and colour interpretation in the image.

Learning activity 3: Work in groups, where students design a small questionnaire for a socioeconomic research survey applied to a specific case. The work is organized in four stages: (i) formulation of the main question for the research; (ii) elaboration of a conceptual model for at least three groups of variables, indication of the relationships between groups and identification of the variables within each group; (iii) definition of each variable and description of how to carry out the measuring; and (iv) elaboration of the questionnaire and preparation of the presentation. Optionally, the groups can also outline the plan for data collection and the plan for survey analysis. The different groups present their results and these are discussed in class; additionally, a discussion on the criteria for using each technique is performed.
Percentage of contact: 100%
Assessment system 1: Written exams, composed by questions provided by the different lecturers of the Unit. The questions are concrete and require a short development. The exam assesses the content of lectures and the understanding of the practicals which are not evaluated separately, through the realization of exercises similar to those developed during the practical sessions.
In the written exam, the questions are marked according to the technical and conceptual precision of the answer, and to the reasoning approach, and the exercises according to the understanding of the methodology applied and the validity of the results obtained.
Weighting: 72.5% of the final score of the Unit
Assessment system 2: Global assessment of the results of the cartography practicals (1) and (2) and the geographic information systems practicals (4) to (8) by the tutoring lecturers. In the assessment of practical (1) the suitability of the cartographic references collected in relation to the assumption, the correction in the indication of references and the formal presentation of the information will be assessed. In the assessment of practical (2) the correction in the photointerpretation of the elements required and the suitability of the level of detail to the working scale, the integration of all elements in one map, the correct representation, the cartographic design skills and the composition and final presentation of the map will be considered. In practicals (4) to (8), the synthesis of the results and their validity will be assessed.
Weighting: 24% of the final score of the Unit (cartography: 7%, GIS: 17%)
Assessment system 3: Global assessment of the results of the group work by the tutoring lecturers. Understanding of the methodology applied, the pertinence of the questionnaire elaborated and the criteria put forward in the joint discussion will be assessed. The score will be the same for all components of each group.
Weighting: 3.5% of the final score of the Unit
