Urban heat island (UHI) is one of the significant urban ecologycal problems. Many
researchers emphasize the necessity of UHI analysis to
support city planning and urban space design. We used the method of heat mapping with
satellite images and heatcameras to measure
surface temperature. Land surface temperature maps were prepared from 56 images of
distinct summer days in the years 2013-2016.
The field survey heatcamera images were prepared in 2016. We mapped and analyzed the
spatial structure of the UHI phenomena for
Debrecen, the second largest city of Hungary. The hottest areas are industrial and
commercial buildings and railway stations. The most
important cooling and conditioning elements are forests, parks and reservoirs. The
land surface temperature map is available on the
internal website of the municipality to support future city planning.
