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)

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)

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...
