The paper "Analysis of Surface Temperatures Distribution over Paris" is an excellent example of a research paper on environmental studies. This study seeks to determine the ability to use GIS software in satellite data analysis. The study uses the QGIS for the task of determining the Land surface temperature profile of Paris. The analysis of data involved 4 steps namely: the conversion of raster bands from digital Number to reflectance and At satellite, land cover classification, reclassification of the land cover classification to emissivity, and then the conversion from At satellite temperature to Land Surface Temperature.
The study shows the ability to analyze the spatial using QGIS. This emanates from the successful analysis of Paris surface temperatures. The results indicate there is a differential spatial distribution of temperature in Paris. From the study, it can also be concluded that Paris experiences the UHI phenomenon due to differential temperatures between adjacent locations. Introduction Background The surface temperature of any given place is a very important component of life. The temperatures determine the weather pattern of a region (Lydolph). Paris has been an area of interest for temperature studies due to observed heat waves and related temperature-related effects including other weather elements such as wind, which depend on the surface heat properties (Santamouris).
Determination of the general surface temperature distribution can be hard to find using the surface measurements such as spatial recording. However, satellite information can give a detailed surface temperature representation. This is achieved based on the fact that satellite mapping takes a snapshot of the spatial characteristics of a given place and stores it for later retrieval and study (Lyon and McCarthy). Bearing in mind that the general surface temperature distribution of Paris is of interest due to the observed phenomena related to thermal characteristics, the study undertook to investigate the Land surface temperature distribution over the area.
This could only be achieved through an analysis of the satellite information about the area. Only this source has the ability to give real surface information including but limited to the temperature. By studying the spatial surface temperature of the region, it is easy to conclude and hence find a possible solution (which may be long term) to the problems associated with temperature.
Usually, the raw data provided by the satellite can be very useless since nothing can be concluded from it. It must, therefore, be analyzed to produce maps that be interpreted on a visual basis (i. e, visually useful). One such tool for analyzing the data is Quantum GIS. This is a desktop geographic information system (GIS) application that enables easy data viewing, editing, and analysis into something visually meaningful (Lyon and McCarthy). The software is known to be among the best GIS software with which users are able t create maps with multiple layers using different map projections.
Based on the ease of use and improved accuracy and reliability (Westra), the software was adopted for this study. Before describing how this software was used in the analysis of the surface temperature, it is important to note the objectives of the study. Objectives Pursuant to the study, the main objective of this study is to assess the ability to use the GIS software in analyzing data into a visually meaningful and correct display.
