Modeling of environmental monitoring data processing in a cloud infrastructure

A model of a cloud-based system for processing environmental monitoring data is proposed. The model takes into account the multi-tier web applications and the heterogeneity of the input flow of applications. As a characteristic of the efficiency of the data processing system, an additive criterion is chosen that takes into account the volume of processed requests and the load on the resources of the cloud infrastructure. The approach under consideration will allow creating a basis for modeling the processes occurring in natural-technical systems (NTS), analyze data processing processes during monitoring of key performance indicators of NТS and ensure that these indicators meet the requirements specified in SLA agreements through the use of alternative data processing strategies.

LOCALIZATION OF SOIL MONITORING DATA PROCESSING

A tree of data analysis for the formation and preprocessing, storage and protection of data based on Big Data and Blockchain technologies has been developed. The developed algorithm allows for the classification of data on the state of the field, split testing of data, forecasting and machine learning for the implementation of differential irrigation with sprinklers.

Watershed of a small river as source of contaminants and biogenic elements

There is considered methodology of estimation of contaminants and biogenic elements intake into water objects from urban watersheds by municipal non-point runoff. We used the Volkovka River in St. Petersburg and its watershed for the research because the watershed is characterized by high degree of variety and includes all possible types of urban areas: multi-storey residential constructions, industrial areas, green spaces, cemeteries, wastelands, and even agricultural areas. The research included the monitoring data processing, the watershed analysis by GIS-technologies, and field studies.

Remote Monitoring System of Geological Exploration in Lava Area Based on GPS

A remote monitoring system for geological exploration in a lava area based on GPS is designed. The system mainly collects geological exploration data in a lava area by means of multi-S integration through the data acquisition module of geological exploration in a lava area. Then the data collected are transmitted to the data analysis and management module of geological exploration data in a lava area by using a GPS network, and the data analysis and management module of geological exploration data in the lava area is exploited. The monitoring data processing method based on the unascertained filtering method is used to remove gross errors in geological exploration data of lava area, identify abnormal values in geological exploration data of lava area, and transmit the abnormal values to the GPS-based geological anomaly location module. The GPS-based geological anomaly location module locates the geological anomaly according to the abnormal values, thus completing the remote monitoring of the exploration of the lava area based on GPS. The test results show that when the system is applied to remote monitoring of geological exploration in a lava area, the positioning error of small soil caves is small, and the reliability of monitoring data is high, which meets the needs of remote monitoring of geological exploration in a lava area.

Alternative Approach to the Methodology of Ecological Normalization

The paper considers legal, regulatory/methodical, and scientific foundations of the system of ecological normalization of negative impacts caused by economic activities upon water environment by setting norms of quality and permissible impact.The developed system is represented by a combination of methodological provisions and instruments based on the analysis of the best available techniques in the sphere of monitoring data processing, the use of linear trends of the compressed characteristics, and indirect unified assessment of negative impacts as responses to any kind of economic activities. To provide experts with an objective toolbox and specified provisions we have developed a package of water/protective standards to support assessment of the water quality depletion, water systems degradation, actual and permissible anthropogenic load, and solution of other water/environmental problems. Approval of standardized algorithms of expert actions based on the impact monitoring data gives grounds for possible ecologization of the Water Code in order to assess the aquatic systems safety and to implement the state regulatory function of natural resources protection.
