The GeoService Urban Heat Islands (UHI) from Harris Geospatial Solutions locates and quantifies urban heat islands (UHI) within a certain area and provides the results as GeoTIFF and pdf reports - automated, standardized and cost efficient.
Agencies, governments and companies get easy access at low costs to support their smart city projects or any landscape planning where thermal impacts need to be understood. Just select your area of interest and analysis period below and the result will be provided to you.
Urban Heat Islands (UHIs) are a measurable phenomenon that cause temperatures in urban areas to spike more than 9 degrees Fahrenheit higher than the surround suburban and rural areas. This effect is caused by radiated heat from man-made surfaces such as buildings, roads, and other structures. In addition to the radiated heat, airflow is impeded by tall buildings, and traffic and lack of vegetation can potentiate the effect.
According to the EPA, common risks to communities that experience increased temperatures due to the UHI effect include increased energy demand which is a driving factor of increasing air pollution. Further, increased temperatures in urban areas are also associated with increased greenhouse gas emissions, heat related illness, and water quality issues.
In order to mitigate the effects of Urban Heat Islands and take protective actions, it is first necessary to locate and quantify the effects. Use the Urban Heat Island GeoService to get this information quick, standardized and cost efficient.
The GeoService Urban Heat Islands provides essential localized information on seasonal thermal variations, and by detecting temperature peaks, delivers a foundation for the further assessment of heat loss from buildings and roads, air quality and urban climate, which are essential for human health and welfare, urban planning and environmental sustainability.
Without time-consuming data search and expensive on-site surveys, research organizations, as well as real estate, construction and insurance companies can access, quickly and at low cost recent and historical information on the extent of thermal anomalies within urban areas. They can use UHI Service to evaluate urban development and to simplify the estimation of waste heat and energy consumption for an urban area.
Governments save time and efforts in meeting their duties to secure air quality for their citizens, to reduce the compounded impacts of global climate change on urban areas, and to preserve the environment and promote sustainable development.
Use Urban Heat Islands to:
- Monitor heat loss from buildings and roads
- Determine thermal emission peaks
- Support urban planning projects and landscape management
- Examine energy consumption, waste heat and urban climatology
- Assist in the determination of air pollutants and greenhouse gases
The Urban Heat Islands application is based on peer-reviewed scientific methods and has been implemented using state-of-the-art geospatial data processing tools and architecture. Urban Heat Islands maps identify thermal peaks and thermal variation by using series of images within the selected analysis period. The thermal peaks overlay a basemap which is used for locational reference, visual assessment and further analysis.
The UHI GeoService is based on Landsat 8 satellite imagery. The resolution of the map is determined by the resolution of this satellite imagery. The 16-day revisit time of Landsat 8 defines the maximum number of available images within the selected time period. However, if the cloud coverage is above 20% for a specific image, it will be discarded and thus the total number of selected scenes, used for the map generation, will be reduced. A minimum of one scene is sufficient for generating an UHI map.
Output files are in standard GeoTIFF, PNG and PDF formats, allowing for immediate visual interpretation and direct incorporation into reports and presentations, as well as ingestion into other geospatial data and image analysis software packages.
The Urban Heat Islands package consists of the following output files:
- UHI image (GeoTIFF)*
- UHI map (PNG)*
- UHI map (PDF)*
*All output files are distributed as single integrated ZIP file. You can download an example file here.
Configure and order
- Area of interest (AOI): Use the map to define your AOI.
- Start date: Select a date at least 6 months in the past. All suitable imagery after that date and within the analysis period will be used for the statistics.
- Analysis period: The analysis period is set to 6 months.
- Remarks: Please enter your desired map title (max 20 letters) here.
Please let us know if you encounter any problems at email@example.com. Our GeoExperts are standing by to optimize the product configuration according to your needs. We are happy to get your feedback.
- UHI GeoService uses a robust algorithm that performs well for most conditions; however, if there is a lack of satellite imagery with low cloud cover the reliability of the method is limited.
We provide the number of used scenes together with the resulting UHI map.
- The PDF and PNG files are limited to an area of 900 km2 calculated from the center of your AOI. The TIF image covers your complete selection.
