The main goal of revitalization is to improve the spatial condition of the city, which improves its image and increases the value of space. Any revitalization process requires the acquisition of geolocation data. This data can help visualize the spatial changes that were the goal of revitalization efforts. Acquiring such data is not always easy and requires the use of multiple sources of GIS information. The purpose of this paper is a spatial presentation of the analyzed areas with their identification before and after the revitalization process using spatial data made available in an open resource on Google Maps map application. Data is presented for two cities: Bydgoszcz (Poland), Varna (Bulgaria), characterized by a similar population. The paper uses current and archival orthophotos of the revitalized areas, Street View panoramic views from street level and own photographic documentation. The results of the analysis show that regardless of the stage of revitalization, the use of spatial data is essential in the designation of a degraded area, as well as later in its design, monitoring and management.

This paper compares the spatial distribution datasets on monthly precipitation totals derived from the Famine Early Warning System Network FEWS NET service (CHIRPS 2.0 product) and the International Mission of the Global Precipitation Measurement GPM (IMERG v06 product) with ground-based observations of a stationary weather stations located in the steppe region of the Crimean Peninsula in order to assess the representativeness of the precipitation spatial distribution and the applicability of the datasets for water balance calculations and agricultural crop dynamics modeling. A close convergence was observed between the estimated monthly precipitation totals and the precipitation gauge data during the study period (January 2017 - July 2020), with mean correlation coefficients of 0.75 and 0.73 for the GPM IMERG and CHIRPS, respectively. Both products generally overestimated the precipitation values compared to the measured data, with GPM IMERG (final run) exhibiting the greatest overestimations (1.3-2.1 times the weather station values). Our results demonstrate the requirement of GPM-derived precipitation estimations (particularly those from the GPM_3IMERDL v06 daily accumulated late run dataset) to be additionally verified and calibrated based on data from regional weather stations or the CHIRPS 2.0 product (if available).

Planning and marine spatial development are based on an exceptionally wide range of knowledge and information which are used in the process of creating plans and their later evaluation. The first type is spatial data describing the present state of the natural and anthropogenic environment within a widely understood spectrum. Second type data are statistical information describing spatial occurrence in the environment. Geoinformation within a planning process is hugely important, as the quality of spatial data influences decisions made and final results of planning work. Undoubtedly, efficient spatial database management and creating a compatible system to operate it are the key elements of effective work in a planning process. In Europe, the monitoring process together with creation of tools supporting database management is highly developed. There is a range of examples for the use of the spatial information systems in work linked to preparation and evaluation of spatial management plans at sea. Due to the specifics of works related to spatial planning in Poland, this paper presents a new solution for the future monitoring of the generated plans. The nature of this paper is determined by the local approach to taking advantage of the ArcGis software related with the use of a range of tools in the monitoring approach to plans of spatial management of the Polish marine areas. The purpose is to demonstrate a selected tool which is supposed to improve the planners’ work, from the point of view of the use of statistical data linked to the dynamics of changes in the coastal area. This is an exemplary use of the tool which might be modified at will, according to the needs of a user. Due to such a solution, the tool can be adjusted to the most of required data based on statistical tables.

Planowanie i zagospodarowanie przestrzeni morskiej opiera się na wyjątkowo szerokim zakresie wiedzy oraz informacji, które są wykorzystane w procesie tworzenia planów oraz ich późniejszej ewaluacji. Jednym rodzajem są dane przestrzenne opisujące aktualny stan środowiska naturalnego i antropogenicznego w szeroko pojętym spektrum. Geoinformacja jest niezwykle istotna w procesie planistycznym, gdyż jakość danych przestrzennych wpływa na podjęte decyzje i wyniki końcowe pracy planistycznej. Niewątpliwie sprawne zarządzanie bazą danych przestrzennych oraz tworzenie kompatybilnego systemu jej obsługi to kluczowy element efektywnej pracy w procesie planistycznym. W Europie proces monitoringu wraz z tworzeniem narzędzi wspomagających zarządzanie bazami danych jest wysoko rozwinięty. Istnieje szereg przykładów wykorzystywania systemów informacji przestrzennej w zakresie pracy związanej z przygotowaniem i ewaluacją planów zagospodarowania przestrzennego na morzu. Z uwagi na specyfikę prac w Polsce, poniższy tekst przedstawia nowe rozwiązanie dla przyszłego monitoringu powstałych planów. Charakter pracy określa regionalne podejście do wykorzystania możliwości oprogramowania ArcGis związanej z użyciem narzędzi w podejściu monitoringu planów zagospodarowania przestrzennego polskich obszarów morskich. Celem jest ukazanie wybranego narzędzia, mającego usprawnić pracę planistów, w ujęciu wykorzystania danych statystycznych związanych z dynamiką zmian strefy brzegowej. Jest to przykładowe wykorzystanie narzędzia, które może zostać dowolnie zmodyfikowane na potrzeby użytkownika. Dzięki takiemu rozwiązaniu narzędzie może zostać przystosowane do większości potrzebnych danych bazujących na tabelach statystycznych.
