Goal. The purpose of this paper is to create a tourist GIS of the Sumy oblast using cartographic materials and remote sensing data, as well as the development of new tourist routes in the Sumy oblast by means of modern geoinformation technologies and ArcGIS, ArcGIS Online, and AllTrails software. Method. The main stages of the creation of Sumy oblast tourist GIS were: search and analysis of the of input materials, necessary for the creation of a tourist GIS; create of the structural block diagram of research works; Satellite image processing, in particular the creation of synthesized images and the use of the Pansharpening technique for a better interpretation of objects; building a digital elevation model for tourist GIS; processing of cartographic materials in ArcGIS; creation of a graphical and attributive database; classification and layer-by-layer data visualization; development of tourism routes by means of ArcGIS Online and AllTrails web applications; analysis of the created of Sumy oblast tourist GIS. Results. As a result of the research: a structural diagram of the main stages of the research has been developed; a graphical-attributive database with information about tourist objects was organized; created a digital elevation model based on SRTM data of Sumy oblast, made the topographic basis of GIS; by means of the ArcGIS 10.3 software a tourist GIS of the Sumy oblast was created, which includes 255 tourist objects of various profiles; using web applications ArcGIS Online and AllTrails, 5 automobile tourist routes with a total length of 1234 kmand 1 pedestrian route 11 kmlong, which pass through the territory of Sumy oblast, have been developed. Scientific novelty. The novelty of the research lies in the methodology for creating a Sumy oblast tourist GIS, the development of new excursion tourist routes and objects, and their visualization based on the use of cartographic materials and satellite images by means of modern GIS, in particular ArcGIS 10.3, ArcGIS Online and AllTrails. Practical value. The research results can be used in the tourism industry, where the priority task is to provide tourists with modern highquality overview, cognitive and cartographic materials, including traditional maps, schematic maps, booklets, and digital maps, 3D models, web applications, audio, video and virtual tours, which are created using the latest digital and GIS technologies, as well as to popularize the tourist and recreational potential of the Sumy oblast among the population.

Spectral Solar Irradiance

Interest has been increasingly focused on the studies of solar radiation across the globe ever since people are more concern about energy conservation. Due to the increment of terrestrial application of solar energy, the scientific interest on solar distribution has expanded from broadband solar energy to its spectral distribution. Measurement of solar radiation with its spectral profile provides knowledge for making important decisions involving resources and energy, agriculture and climate. In remote sensing, the measurement of spectral solar radiation is important for sensor calibration and image enhancement to extract the most information out of a satellite image. The spectral radiation can be measured using spectral radiometer specifically design for measuring solar radiation; however such instruments are expensive and only provide point data which is very limited in most studies. This study aims to provide a rigorous spectral radiation model that predict the spectral solar irradiance in temporal resolution of every minute with spectral range from 350nm to 2200nm under cloudless condition. The parameters used in this model include the distance between sun and earth, time, coordinate, atmospheric interference and terrain effect. Atmospheric sounding data was used in this study to provide the necessary atmospheric parameter in the simulation of solar propagation through the atmosphere. The atmospheric effects considered in this study include Rayleigh scattering, aerosol attenuation and the absorption of water vapor, ozone and uniformly mixed gas. The simulation results were projected onto a digital elevation model to further calculate the effect introduced by the topographic variation and to get a three dimensional solar spectral radiation. The result obtained from this study is compared with spectral solar irradiance data collected during the month of June and July, 2018 with root mean square deviation of 9 watt per meter square at the wavelength of 350nm to 2200nm.
