Abstract

When using aerial thermography to indicate energy-related conditions of buildings in a large investigation area the question arises how to store and present the final product of classified, energy-related data. A full scale study of 7000 buildings demonstrated the need fur computerbased systems and cartographic methods to store, to arrange and to illustrate thermograpic data. A data base was created including aerial thermograpic data, technical data on the buildings and information on energy consumption of each building. The data base consisted of 100 variables. The key-code for the data base was the real estate name and number. The position of each building was given in terms of coordinates of the real estate. The main purpose of the study was to create an energy-related data base to be used for assigning a priority to measurements within the local energy conservation program. The thermographic data was collected with a longwave airborne infrared line-scanner (3-14 um). The technical data on the buildings and their energy consumption were gathered from existing data bases and from field investigations. Thermograpic data, technical data of the buildings and information on energy consumption was classified and different symbols were used to identify the classes presented on thematic maps. Results from this study implies that computerbased cartography is a favorable method to present and illustrate thermographic information on buildings in large investigation areas. The paper deals mainly with the aspect of carthography for presentation of thermographic and energy-related data.
