  Satellite images and aerial photos support settlement surveys and provide valuable information of their physical environment. Aerial photos are excellent tools to overview large areas and simultaneously provide high-resolution images making them efficient tools to monitor built-up areas and their surroundings. Aerial photos can also be used to collect complex spatial data as well as to detect various temporal changes on the land surface, such as construction of illegal edifices and waste dumps. The 10 to 30-meter resolution SPOT and Landsat images are usually insufficient for site specific data collection and analysis. However, the recently available 0.5-meter resolution satellite images have broadened the scope of monitoring and data collection projects. Beyond environmental and urban monitoring, the new available high-resolution satellite images simplify the everyday work of local authorities and will facilitate the development of governmental databases that include spatial information for public utilities and other communal facilities.

  As nature and greenspaces in urban areas are agreed to enhance children’s appreciation towards nature and so the purposes of environmental education, it is of high importance to create spaces in and around schools that allow students to connect to nature on a daily basis. The aim of the study was to analyse functions and other components supporting environmental education appear in the open spaces of school grounds in Budapest, and to understand the main characteristics of school grounds with the highest potential in environmental education. The study points out that the presence of environmental educational functions often depends on the size, urban context and location of the school grounds, however the curriculum of the school does not necessarily influence its open spaces, while the presence of motivated and engaged teachers does. The study reveals environmental educational functions do exist in school grounds of primary schools in Budapest, however they play only secondary role behind active movement and play functions. The schools with the best potentials in environmental education are without doubt the ones situated on large plots in the suburban zone, mostly with a high proportion of green spaces in and around the school grounds.

  Long term temperature patterns helps in assessing changes in the climatic conditions of an area and climatic changes poses a major challenge to the world heritage sites whether it is natural or cultural. Therefore in this study using maximum and minimum temperature data for the period 1960-2021 downloaded from WorldClim 2.1 calculation of mean temperature is done in QGIS environment for the selected UNESCO world heritage sites of Arab Republic of Egypt. WorldClim 2.1 provides finer resolution gridded data downscaled from Climate Research Unit. Trend analysis using linear regression and Mann-Kendall method and Sen’s Slope estimate is used to understand the patterns of mean temperature at all the selected sites. The study reveals that mean temperature at all the selected sites is increasing but since 1990 the sites which are located geographically in lower Egypt are witnessing rapid increase in mean temperature compared to the sites located in upper Egypt which historically witnessed more temperature due to its geographical milieu. This study can help in stimulating the utility of geospatial data in understanding the changes in climatic parameters in relation to world heritage sites. Moreover it can serve as foundation upon which detailed longitudinal site specific investigation can be done.
