The presented research concerning the landscape evolution of the area of the Kazimierski Landscape Park assumed the analysis of landscape changes that took place in the western part of the Nałęczów Plateau in eastern Poland as a result of increased anthropopressure. To achieve this goal, the diverse data was employed: archives of the “Archeological Survey of Poland” obtained from the National Heritage Board of Poland , the registry data from the 16th century made available as part of the “Atlas Fontium” project elaborated by the Institute of History of the Polish Academy of Sciences, old map of the Western Galicia from 1808, a tactical map of the Military Geographical Institute in Warsaw from 1937, and the “Topographic Objects Database” (BDOT10k) obtained from the Head Office of Geodesy and Cartography. Based on the analysed data, maps presenting the development of the settlement network from the moment of permanent settlement of the area up to the present state and maps showing the changes in land use in the Kazimierski Landscape Park over the last centuries have been designed. The results of historical and geographical analyses carried out as part of the research were compared with the results of geomorphological research conducted in the studied area. Verification of the obtained results allowed to determine the scope in which man influenced the evolution of the landscape of the analysed area, including its diversification depending on the historical period and the type of the economy. The process of georeferencing the map of Western Galicia elaborated by colonel A.M. von Heldensfeld from 1808 and the tactical map 1:100,000 of Military Geographical Institute from 1937 covering the research area (14,974 ha) was carried out in the ArcGIS Desktop software. The calibration process was evaluated in the Map Analyst program which makes it possible to analyze the distortions of old maps. Then, vectorization of selected terrain coverage classes and visualization of spatial data were conducted. This way, the land use maps were analyzed in terms of environmental changes that occurred over the past centuries by identifying the areas with the largest development changes. The obtained results were compared with the database of historical objects created for the purposes of this research, based on data provided by the National Heritage Board of Poland and the Institute of History of the Polish Academy of Sciences in order to determine the development trends of the settlement network in the region. The additional statistical analysis made it possible to determine the trend of changes and to interpret the distribution of areas threatened by the occurrence of mass movements with the analyzed anthropogenic determinants.

The city of Algiers (Algeria) is a highly seismic area, and therefore, soil liquefaction poses a major concern for structures resting on sandy soil. A campaign of 62 static penetration tests or cone penetrometer tests (CPT) was carried out on a site located in the commune of Dar El Beïda in Algiers. The soil Liquefaction Potential Index (LPI) values were assessed, for each borehole, based on the simplified procedure of Seed and Idriss. On the other hand, the geographic information system and geostatistical analysis were used to quantify the risk of soil liquefaction at the studied site. It is worth mentioning that the (LPI) was taken as a regionalized variable. In addition, the experimental variogram was modeled on the basis of a spherical model. Also, the interpolation of the LPI values in the unsampled locations was performed by the Kriging technique using both isotropic and anisotropic models. Kriging standard deviation maps were produced for both cases. The cross-validation showed that the anisotropic model exhibited a better fit for the interpolation of the values of the soil liquefaction potential. The results obtained indicated that a significant part of the soil is liable to liquefy, in particular in the northwestern region of the study area. The findings suggest that there is a proportional relationship between the risk of liquefaction and the increase or decrease in seismic acceleration.

Geographic Information Systems offer many algorithms that allow analysis of digital elevation models. They work with both GRID and TIN data, but they are limited to 2.5D models, where one planar (X,Y) position refers to only one vertical (Z) value. In mountainous regions, however, many steep, vertical and even overhung parts of rock walls and slopes occur. GRID and TIN models in a standard projection are not capable to deal with such a relief as they are not able to capture all complexity of steep slopes that can be observed from the terrestrial perspective. Such a perspective can be introduced into GIS via computer graphics software that allows 3D surface modelling by means of mesh, e.g. 3D triangular network. The paper presents a concept that implements 3D mesh in GIS and utilizes vector algebra to analyze such a surface. The idea is based on using normal vectors to compute slope and aspect of each triangle in a mesh. The computed values are saved as their attributes. Complete procedures are written in Python programming language and implemented into popular GIS software to work as a plug-in tool.

The database was created in response to the need of obtaining complex information necessary for efficient management of the Polish coastal zone. Database preparation processes are co-ordinated within the EU PHARE project focusing on harmonising such databases in Estonia, Lithuania, Latvia and Poland. The majority of the information concerns the geographical objects, therefore the database was generated with application of Geographic Information Systems.

The purpose of the present study was to compare the prediction performances of three statistical methods, namely, information value (IV), weight of evidence (WoE) and frequency ratio (FR), for landslide susceptibility mapping (LSM) at the east of Constantine region. A detailed landslide inventory of the study area with a total of 81 landslide locations was compiled from aerial photographs, satellite images and field surveys. This landslide inventory was randomly split into a testing dataset (70%) for training the models, and the remaining (30%) was used for validation purpose. Nine landslide-related factors such as slope gradient, slope aspect, elevation, distance to streams, lithology, distance to lineaments, precipitation, Normalized Difference Vegetation Index (NDVI) and stream density were used in the landslide susceptibility analyses. The inventory was adopted to analyse the spatial relationship between these landslide factors and landslide occurrences. Based on IV, WoE and FR approaches, three landslide susceptibility zonation maps were categorized, namely, “very high, high, moderate, low, and very low”. The results were compared and validated by computing area under the receiver operating characteristic (ROC) curve (AUC). From the statistics, it is noted that prediction scores of the FR, IV and WoE models are relatively similar with 73.32%, 73.95% and 79.07%, respectively. However, the map, obtained using the WoE technique, was experienced to be more suitable for the study area. Based on the results, the produced LSM can serve as a reference for planning and decision-making regarding the general use of the land.

In 2011, the National Institute of Folk Culture in Strážnice was charged to solve the project titled Traditional Folk Dress in Moravia; Identification, analysis, preservation and continually sustainable condition of collection material from 1850–1950. Within this task, a plethora of expert outputs of identification or analytic nature came into being. Many of them were presented to the professional and amateur public in the form of expert studies or publications. The information about documented garments could only be made available thanks to the GIS map web Folk Dress in Moravia. The web shall provide the researchers with source information about the folk garments placed in collections of Czech and Moravian museums. Particular types of garments, such as trousers, vests, jackets, coats, shirts, blouses, skirts and women’s waistcoats or bodices etc. will be identified according to united systematics and the acquired information will be placed in a database. It allows to compare the garments and to form a group with identical properties. Based on these properties, particular types and variants thereof are presented on the map. The depicted pictograms of garments allow to move to a database card, in which not only the source information but also drawings and pattern sketches are included.

In Morocco, solid household waste is often disposed of in open air in unsuitable sites, causing adverse effects on humans and the environment. In the province of Settat, there are eight uncontrolled landfills. The present study aimed to determine the most suitable sites from an environmental and economic point of view to ensure good management on a regional scale. The investigation involved a combination of a multi-criteria method (the AHP analytical hierarchy process) and a GIS geographic information system (ArcGIS) with ten criteria: distance from the ground water, water surfaces, drilling, settlements, forests, roads, highway, land use, slope, and elevation. The suitability map showed that about 18.5% of the study area is suitable for installing a sanitary landfill.

System informacji geograficznej (GIS - Geographic Information System) jest stosowany do zarządzania sieciami wodociągowycmi i kanalizacyjnymi zarówno na świecie, jak i w Polsce co najmniej od kilkunastu lat. Podano ogólną charakterystyką GIS, ze szczególnym uwzględnieniem funkcji i podstawowych elementów jakie tworzą te systemy. W artykule przedstawiono wyniki pilotowego wdrożenia GIS do ewidencji sieci wodociągowej w wybranym osiedlu liczącym ok. 24 tys. mieszkańców. W projekcie wykorzystano oprogramowanie specjalistyczne Mb_GIS Start Edition firmy Megabit z Warszawy. Dzięki temu możliwe było wprowadzenie do bazy danych o 360 odcinkach przewodów, 24 zasuwach i 49 hydrantach. Efekty wdrożenia GIS pokazano na przykładowym fragmencie sieci wodociągowej. Optymalnym rozwiązaniem byłoby stworzenie mapy cyfrowej miasta obejmującej wszystkie rodzaje sieci. Takie podejście umożliwiłoby stworzenie kompleksowych zasobów informacji o uzbrojeniu terenu miasta. Dzięki temu również koszty wdrożenia i późniejszego utrzymania bazy danych byłyby niższe, gdyż rozłożyłyby się na poszczególne przedsiębiorstwa branżowe.

The Geographic Information System (GIS) has been used to manage water-pipe and sewerage networks all over the world (including Poland) for at least a decade. A general characterization of the GIS is given, particular consideration being focused on the function of the basic elements that form such systems. In the paper presented are the results of a pilot study on the implementation of the GIS into the records of the water-pipe network in a residential area of choice with a population of approximately 24 thousand. The project was carried out using a specialized software, Mb_GIS Start Edition (made by Megabit, Warsaw). With this software it was possible to load the database with information about 360 pipeline sections, 24 gate valves and 49 hydrants. The advantages of implementing the GIS are shown taking a fragment of the water-pipe network as an example. Seemingly, the construction of a digital map of the town that includes all network types is an optimal solution, which enables comprehensive resources of information on the territorial development to be established. Then, also the costs involved in the implementation and maintenance of the database will be lower as they can be borne by particular branch enterprises.

Conflict is recognized as a major barrier in socio-economic development. In conflict situations, most sectors such as health, food, shelter and education are adversely affected. The provision of education services to conflict-affected children saves them from becoming a lost generation and contributes to community building. Thus, we conducted this research to investigate the potential of a GIS (Geographic Information Systems) approach and risk assessment based multi-criteria decision making (MCDM) for the allocation of displaced dropped-out children to the most appropriate educational centres, taking into account multiple goals related to cost, distance, risk, etc. A two-stage approach was adopted, utilizing a risk assessment approach, and a location-allocation approach. The risk assessment approach was carried out using GIS and F-AHP (Fuzzy Analytic Hierarchy Process) to determine the risk value of each candidate educational centre in the conflict area. In the location-allocation stage, a mathematical model was developed to allocate all demands to the chosen centres. All presented methods were computationally conducted on real case data provided by direct beneficiaries and stakeholders in the 26 sub-districts in the Idleb governorate, Syria. The computational results demonstrate that the proposed approaches ensure practical and theoretical impacts.

Dzięki szybkiemu rozwojowi Internetu mamy łatwy dostęp do różnych informacji i usług. Niestety, brak opracowanych standardów w zakresie informacji geoprzestrzennej spowodował niemożliwość współpracy oprogramowania różnych producentów i swobodnego dostępu do danych przestrzennych różnych formatów. Właśnie dlatego organizacja OGC rozpoczęła pracę nad specyfikacjami OpenGIS. Jedną z nich jest specyfikacja Sieciowego Serwera MAP (WMS), szerzej opisana w tym artykule. Przedstawiono również internetową aplikację Mapnik, która między innymi umożliwia przeglądanie map zbudowanych z warstw odczytanych z plików programu MapInfo, plików rastra oraz pobranych z serwerów WMS.
