Digital cartographic generalization – study of its thresholds and stages in example of cartographic line
(Wydawnictwa AGH, 2023) Budkowski, Szczepan
Digital generalization of spatial data has been the goal of the research in many research centers around the world. This article presents the evolution of cartographic generalization, drawing the reader’s attention to the change of its nature from analog to digital. Despite the passage of time and developing technologies, scientists have unfortunately yet to develop a uniform automatic generalization algorithm. One of the factors that hinder this process is the high complexity and complication of the whole process. The article is an attempt to answer this problem and addresses the issue of digital cartographic generalization by creating a proposal of thresholds and stages of cartographic generalization depending on the ratios of the numbers of points of generalized objects. The publication attempts to examine the possibility of applying an objective criterion of drawing recognition by examining digital generalization algorithms and setting its thresholds. The practical aim of the publication is to present generalization thresholds on the example of Chrobak’s algorithm. The proposal to make the selection of generalization thresholds dependent on the percentage share of points is a solution that is as simple to use as it is to implement. The method of defining intervals based on the three-sigma rule is a solution that guarantees that the obtained results will be characteristic of the probability density function of the normal distribution, which will define individual intervals most objectively.

Język mapy a ranga dyscypliny
(2007) Krzywicka-Blum, Ewa
Przekształcenie postaci map i upowszechnienie tworzenia map komputerowych w dobie rewolucji techniczno-informatycznej spowodowało z jednej strony poszerzenie zakresu użyteczności map, z drugiej jednak odebrało kartografii należną jej rangę w hierarchii nauk. W artykule podkreśla się wyjątkowość użyteczności modeli obrazowych rzeczywistości nie tylko operacyjną, ale też w abstrakcyjnym wnioskowaniu syntetyzującym.

Mierniczowie przysięgli – rys historyczny zawodu
(Wydawnictwa AGH, 2007) Śmiałowska-Uberman, Zofia
The author presented fundaments of independent land-surveyors profession in the period falling between the two World Wars and subsequent years up to 1952. She pointed out limitations in acquiring proper authorisation and specific of sworn chartered surveyors profession. This occupation carried a considerable social prestige and a different legal statute.

The geomorphology of the Makran Trench in the context of the geological and geophysical settings of the Arabian Sea
(Wydawnictwa AGH, 2020) Lemenkova, Polina
The study focuses on the Makran Trench in the Arabian Sea basin, in the north Indian Ocean. The area is tectonically active, with a system of ridges and fracture zones morphologically separating the Arabian Sea. The study examined the relationships between the topographic structure of the Makran Trench and the regional settings of the Arabian Sea: geomorphology, sediment thickness, geophysical fields, geology and tectonic lineaments. The methodology is based on the GMT scripting toolset. The spatial analysis includes high-resolution datasets GEBCO, EGM2008, GlobSed and data on tectonics, geology, geophysics, sediment thickness and topographic terrain model visualized by GMT. The paper also defined a way in which the proprietary ESRI data format can be transformed into the freely available GMT geospatial data of the geoid EGM2008 model. The geomorphological modeling included the automatic digitization of 300-km width cross-section profiles of the trench demonstrating its submarine relief. The analysis showed a correlation between the geological and tectonic structures, asymmetric geomorphology and geophysical anomaly fields. Gravity data indicate a crustal structure with anomalies generated by the bending of the lithosphere into the Makran subduction zone and density variations in the mantle reflected on the gravity maps. The gravity correlates with lineaments of the geomorphic structures. Bathymetric analysis revealed the most frequent depth (448 samples) at −3,250 to −3,500 m, followed by intervals: −3,000 to −3,250 m, −2,750 to −3,000 m. The declining continental slope correlates with gradually decreasing depths as equally distributed bins: 124 samples (−2,500 to −2,750 m), 96 (−2,250 to −2,500 m), 86 (−2,000 to −2,250 m). The trench is an asymmetric form with a high steepness on the continental slope of Pakistan and low steepness with a flat valley on the oceanward side. The multi-source data integration is important for seafloor mapping and the geomorphological analysis of oceanic trenches hidden to direct observations. The machine learning methods of GMT and cartographic modeling provide possibilities for the effective visualization of the trench. The comparison of the geomorphology with gravity anomalies, tectonic lineation, geological structures and topographical variations provides more detail to studies of the seafloor in the Arabian Sea.

The historical layers of the Lower Silesia towns - the investigations based on historical cartography
(Wydawnictwa AGH, 2013) Eysymontt, Rafał
Studies on the historical layers of historical towns belong to the most important stages of <i>Atlas historyczny miast polskich</i> volumes creation. Lower Silesian towns are investigated mainly on a basis of: - written sources, which reference to the real space is often doubtful - archeological explorations, which results should be confronted with source studies - metrological studies, claiming the original medieval concepts according to their geometrical modularity, although those studies are often loaded with big doses of idealism, - studies on historical cartography, which were performed however usually a few hundred years after the town's foundation, in this case the basic method is relating newer plan to an earlier situation called retrogression. The last method could regard one of the most mutable, but most important element of a city's historical structure, which is the river. Two examples of this kind of analysis, referring to two of Lower Silesian different size cities of Wrocław and Milicz can be mentioned in this case. Changes of river system in these cities drastically influenced the shaping of cities and their environment. Much more controversial is an issue of reconstruction based on the oldest 18th century cartography of the road system, which was shaping settlements network around Wrocław. The method of using historical cartography as a source of knowledge about a city's changes is giving the best results in a case of wide modern fortifications' analysis, though it is often only confirmed by archeological research.

Utworzenie cyfrowej mapy historycznej oraz modelu GIS w oparciu o materiały archiwalne

W dzisiejszych czasach postęp w zakresie technologii informacyjnej stwarza bardzo wiele możliwości. Jedną z dziedzin niezmiernie zyskujących na tym jest geografia historyczna, która głównie opiera swoje badania na kartograficznych materiałach archiwalnych. Rozwój historii i kartografii doprowadził do powstania nowej dziedziny badań, przy użyciu specjalistycznego oprogramowania, jaką jest GIS historyczny. Celem niniejszego opracowania jest wykorzystanie technologii systemów informacji przestrzennej do utworzenia cyfrowej mapy historycznej oraz modelu GIS w oparciu o materiały archiwalne. Przeprowadzono szereg czynności polegających na kalibracji, digitalizacji oraz projektowaniu, aby przekształcić rastrową mapę historyczną do postaci wektorowej. Wykorzystano w tym celu Mapę taktyczną Polski wykonaną przez Wojskowy Instytut Geograficzny w roku 1937.
