AB  - Niche analysis methods developed within the biogeography community are routinely used for species distribution modeling of wildlife and endangered species. So far, such techniques have not been used to explain distribution of people in an area, nor to assess spatio-temporal dynamics of human populations. In this paper, the MaxEnt approach to species distribution modeling and publicly available gridded predictors were used to analyze the population dynamics in Southern Serbia (South Pomoravlje Region) for the period 1961-2027. Population values from the census administrative units were first downscaled to 200 m grid using a detailed map of populated places and dasymetric interpolation. In the second step, a point pattern representing the whole population (468,500 inhabitants in 2002) was simulated using the R package spatstat. MaxEnt was then used to derive habitat suitability index (HSI) as a function of gridded predictors: distance to roads, elevation, slope, topographic wetness index, enhanced vegetation index and land cover classes. HSI and environmental predictors were further used to explain spatial patterns in the population change index (PCI) through regression modeling. The results show that inhabiting preference for year 1961 is mainly a function of topography (TWI, elevation). The HSI for year 2027 shows that large portions of remote areas are becoming less preferred for inhabiting. The results of cross-validation in MaxEnt show that distribution of population is distinctly controlled by environmental factors (AUC  gt 0.84). Population decrease is particularly significant in areas >25 km distant from the main road network. The results of regression analysis show that 40% of variability in the PCI values can be explained with these environmental maps, distance to roads and urban areas being the main drivers of migration process. This approach allows precise mapping of demographic patterns that otherwise would not be visible from the census data alone.

AB  - This paper illustrate experiences of GIS based spatial geodatabase design realization and development for implementation and monitoring of urban plans. As key study authors used Urban Plan of Vrnjačka Banja created in year 2005. Plan was originally created using CAD technology, and it was necessarily to adopt it and convert to standard GIS file formats. Authors explaining methodological framework for creating and managing geospatial database as support for implementation and update of urban plans, and their presentation on Intra- and Internet.
AB  - Rad prikazuje iskustva u koncipiranju, realizaciji i mogućnostima razvoja prostorne baze podataka za potrebe implementacije i monitoringa urbanističkog plana zasnovane na GIS tehnologiji. Kao primer poslužio je Generalni plan Vrnjačke Banje iz 2005. godine. Budući da je ovaj Plan rađen u standardnoj CAD tehnologiji, bilo je neophodno prilagoditi ga i konvertovati u standardne GIS formate. Autori ukazuju na metodološki okvir formiranja i upravljanja jedinstvenom prostornom bazom podataka za urbanističke planove kao podrške njihovoj implementaciji i ažuriranju, te mogućnostima njihove prezentacije na inter- i intranet-u.
