It is possible to make analyses within the field of GIS applying cellular automata. One of the purposes of socio-economic geography is indirect understanding of the phenomenon by analyzing spatial patterns and inferring spatio-temporal processes looking rather for local hotspots. The cellular automata are the tool both for spatio-temporal inferring based on local conditions and data visualization. The evidence is the case study of spatial simulation of Warsaw Urban Area (Poland).
The author verifies the hypothesis that the present layout and extent of the Warsaw agglomeration determines further directions of the city’s spatial development. To this end, he employs a method based on cellular automata theory.
results is through the R statistical environment ( Kabacoff 2011 ) connected to the PostgreSQL database. The database driver and standard R graphical functions perform datavisualisation techniques loaded into the R data frame from a database table. The measurements of the rate of shoreline changes per year between different shoreline positions were made using the end-point rate method ( Dolan et al. 1991 ). The necessary statements executed in the R environment are presented in Figure 9 . Graphical plots of the results retrieved from the database table are presented
datavisualised as point clouds, heat maps and hexagon generalisations. Each topic can be visualised separately and answers can be filtered according to gender, whether the respondent lives in Jeseník and in which neighbourhood the respondent lives. Comments on the points, where applicable (in total 1,538 comments), are also available to read. Furthermore, the city council received the raw data as shapefiles, as well as six simple maps for immediate visualisation. The maps were created in open-source QGIS 2.18, with the utilisation of the heat-map visualisation

knowledge and public preferences. We have discussed geo-questionnaire data content, datavisualisation, aggregation and analysis methods. We have reviewed several issues underpinning the applications of geo-questionnaires in academic research and in municipal planning, including respondent selection and recruitment, data quality, and data representativeness. To substantiate the discussion of method with application examples we have briefly described four recent geo-questionnaire use cases from Poland. The described case studies show the versatility of geo-questionnaire as
The second part of this article involves the assessment of the collected data. The data was checked in terms of completeness (it turned out that some of the data was lacking), topicality, details (the Mrozy commune is a small area), and usefulness for map design (the data deemed useful for visualization, was data with a spatial reference). A database was developed for the purposes of spatial datavisualization. The data in this database was coded, generalized, and described. Furthermore, the database can be updated and expanded as needed.

Subject and purpose of work: The study attempts to examine the trade unfairness and transboundary bottlenecks between Bangladesh and India with a view to prosper a balanced trade and sustained water cooperation.
Materials and methods: The study is based on secondary data and statistical information. Mixed research methods such as qualitative, quantitative and data visualization techniques are adopted in this study to assess the political economy of river basin management, loss and damage assessment and trade situation assessment.
Results: Due to upstream intervention, the North-Western region of Bangladesh has lost 4254218 metric tons of rice production during 2006-2014 cropping years which value is $1036 million. During the same period, the trade deficit of Bangladesh stood at $5.58 billion with India due to the diverse tariff and non-tariff barriers which triggers tension between this close neighbor.
Conclusions: The trade and water co-operation should be extended among the South Asian countries including India and Bangladesh without delay to obtain the maximum benefit and economic prosperity.
