 GEOGRAPHIC INFORMATION TECHNOLOGY EXTA45

Higher education credits: 15. Grading scale: TH. Level: G1 (First level). Language of instruction: The course will be given in Swedish. Compulsory for: L2. Course coordinator: Karin Larsson, karin.larsson@nateko.lu.se, GIS-centrum. Prerequisites: Passed practical exercises in VGMA01 Geodetic Surveying. Recommended prerequisits: FMAA05 Calculus in One Variable and FMA420 Linear Algebra. Assessment: In order to pass the course the student is required to have passed the written individual examination test and to have completed passed exercises and assessments. Most exercises are compulsory. The final grade for the course is based on the written examination test. Students who fail the ordinary test will have an opportunity to take another test in close proximity to the ordinary test and also at the end of August every year. Parts: 4. Further information: Teaching consists of lectures, practical exercises and field measurements. Most practical exercises and participation in the field measurements are compulsory. Assessment takes the form of a written examination in two parts. For more information contact Centre for Geographical Information System. Home page: http://www.nateko.lu.se.

Aim
The aim of the course is to get basic knowledge of concepts and methodologies within geodesy, surveying, cartography and photogrammetry as well as management and analysis of geographical data with geographic information systems (GIS). In addition a deeper knowledge in geodesy is accuired.

Knowledge and understanding
For a passing grade the student must

• be able to describe different conceptual models for spatial phenomena,

• be able to describe different data models for digital geographical data (raster and vector), and how these are stored in computers,

• be able to explain how map projections are constructed and how they can be used,

• be able to describe fundamental cartographic methodology,

• be able to understand and apply basic methods for spatial analysis,

• be able to explain basic theory on spatial interpolation,

• be able to describe quality measures for spatial data and error of propagation in spatial analysis,

• be able to explain basic concepts in photogrammetry,

• be able to explain calculation methods for transformations between different plane and sperical coordinate systems, as well as understand the connections to map projections,

• be able to briefly describe the principals for data capture using remote sensing.

Skills and abilities
For a passing grade the student must

• be able to organise and manage geographical data in computers

• be able to, independently and within groups, solve predefined problems using basic analyses of geographical data, mainly in vector format, with standard GIS software,

• be able to present results and work flow from data capture and analysis of geographical data for specialists and laymen, with maps, graphics and simple text,

• be able to apply standard methods transformation between coordinate systems,

• be able to execute interpolation of geographical data.

Judgement and approach
For a passing grade the student must

• show awareness of, and confidence in, using geographic information and analysis within surveying,

• be able to critically assess geographical data and have achieved a critical attitude towards analysis results,

• understand the importance of interaction between the different aspects of geomatics in order to appraise the plausibility of achieved results.

Contents
Lectures cover the basic theory of cartography, spatial phenomena, geographical data and analysis, map projections and sperical geodesy and an introduction to photogrammetry. Basic geostatistics and quality aspects represented by error propagation theory are also treated. Through calculation exercisis and a number of practical computer based exercisis the students learn how to structure geographical data, perform basic geographical analysis and finally present geographical information. He/she will also get an overview of geographical data bases used by governmental and municipal authorities, the main usage of these data bases and how their quality can be described. In an extensive application exercise the students collect and compile data from different national and regional data distributors, compile the data and execute analysis relevant for surveying purposes.
