JOINING OF HISTORIC AND NATURE HERITAGE IN URBANIZED LANDSCAPE: CASE STUDY MANOR PARK CECHY POD KOSIREM

(STEF92 Technology, 2025-12-27, Ivo Machar, Vilém Pechanec)

Show more

Old manor parks are generally considered as important features of historic heritage in European cultural landscapes. But these parks are not only historic monuments. Because of presence of veteran trees and other biological legacy (such as dead wood), historic manor parks can be biodiversity hot-spots in urbanized landscapes. This study present results from long-term comparison of bird diversity in large old manor park in Central Europe (Czech Republic). Based on bird species richness comparison between 1997 and 2...

ANALYSIS OF THE LOCAL ENVIRONMENTAL CONDITIONS OF LEGUMES USING GLOBAL DATASETS

(STEF92 Technology, 2017-06-20, Brus Jan, Tomas Burian, Vilem Pechanec, Petr Smykal, Martin Duchoslav)

Show more

The recent development of remote sensing technologies and rapidly accumulating environmental data derived from geographic information systems (GIS) now provide information on the patterns of terrestrial environmental variation at global and continental scales. Moreover, the past decades, an extraordinary amount of work has been undertaken to map species distributions and use the collected information to identify suitable habitats. Remote sensing metrics have become an integral part of SDM studies and contribute th...

THE INTEGRATION OF SENSOR DATA INTO GIS ON THE EXAMPLE OF SPECTRAL REFLECTANCE SENSOR

(STEF92 Technology, 2017-06-20, Tomas Pohanka, Vilem Pechanec, Alexander Mraz)

Show more

The aim of the article is an example of how to handle the process and visualize data from the sensor SRS in a GIS environment. Spectral Reflactance Sensor (SRS) is a contactless position sensor system manufactured and distributed by Decagon that monitors vegetation cover, and depending on the use of sensors allows for the Normalized Difference Vegetation Index (NDVI) or Photochemical Reflectance Index (PRI). Values of the spectral reflectance are gradually transferred from the field sensor to the PC environment, a...

WEB-GIS APPLICATION FOR ANALYSES OF THE SENSORS DATA ON THE WEB

(STEF92 Technology, 2017-06-20, Tomas Pohanka, Vilem Pechanec)

Show more

The article presents a development of the Control centre prototype for sensors network. Our Control centre is a web-based information system that supports management of sensors, their data storage in PostgreSQL/PostGIS databases and data analysis. Databases are remotely connected into Control centre. Therefore, they can be stored in different machines or services like Microsoft Azure, Amazon Web Services or Google Cloud Platform, etc. Analytical tools of SQL, Spatial SQL and Python languages are used. Currently, t...

MODELING OF SURFACE RUNOFF IN THE ARCGIS SERVER

(Stef92 Technology, 2011-06-20, Vilém Pechanec)

Show more

The aim of paper is information about a complex model for computation a surface runoff as an ArcGIS geoprocessing tool. Th e formulated LOREP model represents an application for the identification and loca lization of areas with low flood storage capability. The procedure of computation of te rritorial specific surface runoff is based on a combination of specific functions in LOREP as hydrological equations of the runoff curve number method and spatially distributed unit hydrographs. Model involves a transformatio...

MODELING SPATIAL DISTRIBUTION OF ECOTONES IN GIS

(Stef92 Technology, 2011-06-20, Vilém Pechanec)

Show more

The landscape structure, its components and their developments are possible to monitor from several, mutually complementary aspect s: arrangement of gradients (abiotic and biotic) across the territory without signifi cant and sharp boundaries; arrangement of areas in the mosaic of the landscape; network of areas and corridors; system of boundaries and rims in the landscape mosaic [1]. The investigation into ecotones enabled a better understanding of the causal relationships between certain landscape elements, land...

MONITORING OF SNOW RISKS BY GEO-SENSORS IN URBAN AREAS

(Stef92 Technology, 2011-06-20, Vilém Pechanec)

Show more

Monitoring of environmental components, in relation to changes in global biochemical cycles and the presence of their deposition, is one of the world`s most attractive areas of research. This area plays an important role in the sphere of crisis management. One of the dominant components of the environment is water, in all states, especially in forms of snow and ice. Monitoring of weight and height of snow deposition concentrations is the main task of research projects of envi ronmental, geographical and technical ...
