This paper discusses some of the problems involved in evaluating seasonal thermal environment in various kinds of residential areas, and also compares the thermal environment with land coverage of these areas. Average surface temperature and average spectral reflectances scanner imagery. The data used in the analysis have been gathered four times (at noon and in the early morning on clear days in summer and in winter) with an aircraft multispectral scanner at an altitude of approximately 3000 ft in Tokyo. Results of this analysis are as follows; 1) Comparison of the surface temperature in each residential area in winter with that in summer shows an agreement in their tendencies. 2) The spectral reflectances in winter are lower than those in summer. 3) Regarding the surface temperature, it is correlative with the ratio of building coverage to lot or that of pavement to lot in the early morning, while with that of wooden buildings to lot at noon. 4) Visible and near infrared bands are not correlative with land coverage.
