to learn why. Is there any difference based on the original climate? Is it the city itself? We set out to answer that question.
Figure 1. The distribution of urban heat is correlated with the distribution of impervious developments compared to the cooler, and more forested, rural areas.
GIS (Geographic Information Systems) is using cartographical data to measure things such as climate, rainfall, or ambient temperature or humidity. Cartographical data can include heat maps, land cover databases, rainfall patterns, and so on. Most GIS data comes in the form of raster and vector data. Rasters are dot matrixes –similar to pixels- while vectors are made of shapes and lines. Some of the most useful modern GIS data comes from space-borne satellite
