31 May – 11 June 2004
Castellón, Spain
Summer school teaching unit:
Data Acquisition
Lucilene Antunes C. M. de Sá
Cartographic Engineering Department – DECart
Technology and Geosciences Centre – CTG
Universidade Federal de Pernambuco – UFPE
Session 1: June 1: 90 min. + 90 min. (morning)
Session 2: June 2: 90 min. + 90 min. (afternoon)
Session 1:
In this session cartographic concepts, cartographic coordinate and projection systems, systems, spatial data, and geographic information systems will be broached. There will be a practical part including a simulation of area mapping. Groups will be formed carry out the practical.
1. Cartographic Concepts
2. Structure of Spatial Data
3. Spatial Data and Geographic Information
4. Cartographic Design and Geographic Information System
Session 2:
In the theory data acquisition and quality data will be broached. To conclude the critical analyses on the simulation mapping projects based on the concepts in the Unit, initiated in the previous session. Each group of students will make a presentation of their first conclusions and their critical analyses about the simulation for mapping project.
1. Data acquisition
2. Quality Data
3. Data conversion problems
4. Presentation
5. Discussion
The goal is that students completing this teaching unit, should be able to answer the following 7 questions:
Ø What spatial data are used in the application?
Ø What spatial data structures are used in the application?
Ø What reference systems (coordinate and projection system) are used in the application?
Ø When working with GI we need the same reference and coordinate system, such as in the system projection.
Ø Various projections are available for usage and each one may cause distortion of the area, distance direction or shape of spatial objects.
Ø Is it possible to explain the accuracy needed in the application?
Ø What are the sources of spatial data that you will need for the acquisition of data?
Ø To elaborate the Cartographic Design is necessary before the data acquisition.
Ø To show that GI is not only what is visible on the surface of the Earth.
Ø To make possible the analysis between the sources of data and the quality data.
