Assessment of the 2010 Kura river flood using remote sensing data and GIS tools
(Wydawnictwa AGH, 2017) Aghayev, Amil T.
In the Kura River basin fl oods occur frequently and pose a major threat for the local population. This research aims to test if freely available remotely sensed data may provide valuable information on flood extent in this region. Flood in 2010 was analysed as a flood event example. Various maps illustrating this event were collected and compared to satellite Landsat data. A map of the fl ooded areas was developed with ArcGIS 10.2.1 software. Attention was paid to the identifi cation of inundated areas. It was found that there were serious faults in the map prepared by the responsible government agencies. On the basis of satellite image interpretation, districts completely and partly damaged by the flood were determined and mapped.
Analysis of changes in drafting a base map in view of amendments to the provisions of law
(Wydawnictwa AGH, 2017) Buśko, Małgorzata
The main subject of the study is comparison to the standards for the preparation of the base map in view of the amendments to the legal provisions, which have been taking place in Poland over the last thirty years. The scope of the changes to the editing of the cartographic content of the base map was analyzed, with particular emphasis on the form and content of the presented descriptions. The map preparation standards were compared [8], based on the Technical Guideline K-1 of 1998, and the amending Regulation of 12 February 2013 on the database of the surveying records of public utilities, the database of topographic objects and the base map (hereinafter referred to as the BDOT Regulation, 2013) [14], as well as the amended Regulation of 2 November 2015 on the database of topographic objects and the base map (hereinafter referred to as the BDOT Regulation, 2015) [15]. These Regulations, in conjunction with the amendment to the Geodetic and Cartographic Law of 2014 [20], have resulted in historic 6 changes in the approach to the base map, signifi cantly changing the form of its records, the scope of the data to be covered, and the editing, i.e. its visual aspect. The current assumption is that the base map is in fact a report generated from six databases, kept and updated simultaneously [1, 6, 11]. The aforementioned comparison referred primarily to the descriptions, map editing, as well as to the conceptual level.
Generate real total radiation spatial distribution of solar radiation using cloud mask algorithm
(Wydawnictwa AGH, 2017) Pietras-Szewczyk, Małgorzata
This paper describes a method for analysing the spatial distribution of solar energy potential based on calculated solar irradiation using GIS (Geographical Information System). GIS GRASS programme provides an opportunity to create a spatial distribution of solar radiation, taking into account such important elements as terrain, atmosphere, pollutants, water and aerosol in atmosphere, clouds. In this paper one of these elements are taken into account: the impact of the cloud cover on incoming value of solar radiation and the methods available for calculating this impact. The author considers how to calculate the incoming solar radiation under the real-sky conditions.
The theory of pseudo-radiation local emitters value of properties with a differential propagation of prices wave
(Wydawnictwa AGH, 2017) Polny, Lesław; Wójciak, Ewelina
The level of transaction prices arises from preferences of potential buyers, that is, from the current supply-demand relationship for individual market characteristics that diff erentiate the property from one another. However, you can take arbitrarily, but with a high probability that the largest share in price or in value property has its allocation in market space. The easiest and the most common price distribution model is the theorem that the highest form in the city center, the lowest observed in the periphery. Realignment of this doctrine was made by building a set of theses remaining in coherence with the author's conception theory added: on the right-area real estate market, there are at least two emitt ers price, that means points on which unit prices are rising (emitt ers progressive) or decrease (emitt ers regressive) in pseudo-radial progress. By this, we mean intermitt ed price change relative to allocation real estate in design space with differential propagation of carrier prices wave, i.e. with variable development trends. Analysis of signal transmitt ed by polarizer pricing, assisted the GIS environment, based in Krakow's housing market as a representative test material, assuming the being of three uncorrelated emitt ers. This made it possible to demonstrate and sustain the theory of pseudo-radiation (many) local emitt ers' value property with a diff erential propagation-pricing wave and provide a vision its development, based on laws mechanics wave propagation on mirror water with a parallel assumption existence invariant prices islands.
A comparison of accuracy between point clouds from convergent images and spherical panoramas
(Wydawnictwa AGH, 2017) Szlapińska, Sylwia; Tokarczyk, Regina
The work includes the results of a comparison of point clouds made on the basis of convergent images and spherical panoramas from the photos taken in the same center of projection. The results were compared for the group of convergent photos and panoramas in relation to accuracy, cloud density and measurement economics. The research was carried out on the test fi eld inside a large building. The convergent photos and panoramas were taken using the Canon EOS 5D camera. The robotic camera mount GIGA PAN Epic Pro was used to make panoramas. For calculations and building models the Agisoft PhotoScan application was selected, as it has a function of automatic orientation and adjusting photos. The comparison of point cloud accuracy, from which the control point coordinates were taken, has shown that the accuracy of the model made from the photos was 19 mm, and the accuracy of panorama model was 73 mm. As the worse result of panorama cloud accuracy may be caused by much lower density, the eff ect on their accuracy was also checked by making an analytical determination of control point coordinates at the stage of photo and panorama orientation. The analysis has proven that the model made of convergent photos is more accurate (20 mm) than the model made of panoramas (36 mm).
