GyroScan - Elaboration of innovative method for monitoring the state of agrocenosis with the use of remote sensing gyro system in terms of precision farming

The aim of the project is development of the Decision Support System based on the remote sensing method for precision farming (for determination of needs for agricultural practices). This method will be also applied for assessment of the degree of degradation of meadows (the method will refer to biodiversity of examined meadows) and for the carbon dioxide balance between the soil – vegetation and the atmosphere. The analysis will be performed for most important crop: wheat and maize, in 2 regions. Meadows will be examined for the Wieprz river valley.

The advantages:
1) substantial limitation of data derivation costs,
2) air-borne data are more representative and more costand time-efficient than soil and plant analyses and give spatial data what is more precise for precision farming than insitu point measurements,
3) ensuring all benefits of precision farming, which results in substantial reduction of cost and environmental benefits,
4) development of remote sensing method for evaluation of CO2 exchange will ensure faster, cheaper, and easier derivation of data required for greenhouse gas balance.

The project will be implemented the stages of research and development of the remote sensing monitoring system, ground and air-born investigations, and design of a decision support system for precision farming.


Integrated system for monitoring ground deformations using radar interferometry with persistent scatterers

Project leader: PhD Dariusz Ziolkowski
Duration: March 2014 - February 2017

The main aim of the project is to elaborate the integrated system for monitoring ground deformations using satellite radar interferometry with PSInSAR persistent scatterers, precise levelling and measurements from permanent GNSS stations. The research is carried out within Warsaw area and in its surroundings. The study is done both for large area movements of Warsaw Pan and for local deformations caused by metro construction and other elements of infrastructure.

In the radar interferometry project the following types of microwave data are used:
- ERS-1/2 data collected from 1992 till 2010 (over 300 images)
- ENVISAT data collected between 202 and 2010 (over 200 images), acquired from nine different ascending and descending orbits
- High-resolution CosmoSkymed images collecterd from 2011 till 2016 (over 100 images)

Measurements from permanent GPS stations will serve for absolute georeferencing of the results, while precise levelling and the dedicated experiment will be used for assessing accuracy of the proposed solution. Determination of local and regional ground deformations will be interpreted in the context of geological structure of the study area and impact of technical infrastructure objects on ground.
