Andrieu, Julien
Remote sensing is a powerful tool for environment monitoring for because most of the remotely sensed data is intercomparable in space and time. In other terms a correct analysis of remotely sensed data enables to detect the same objects in different places (therefore, to map all the objects of a region) (Gosh et al., 2022) and same objects in different periods (therefore, to map changes) (Andrieu, 2017; Andrieu, 2018, Andrieu et al., 2019).
Remote sensing is progressively changing from a little number of data sets with low to moderate resolution (spatial and temporal) (Andrieu, 2017; Andrieu et al 2019) to a large number of data sets of high to very high resolution (Andrieu, 2018; Gosh et al., 2022). Intercomparability has somehow been the “victim” of the target put on resolution. Mapping changes in land cover, or in vegetation, in a country like Sri Lanka with data as LANDSAT time series would suffer from 2 main weaknesses. First, a lot of different scenes are necessary, creating errors on the edges between two scenes. then most of the images contain important cloud cover. It’s even worse with Very High-resolution imagery either the expensive one or the free one accessible on Google Earth.
For these reasons this conference will illustrate the potential of a very different kind of data, rarely used on Sri Lanka, and however having a high potential to monitor environment. The Very high intercomparability of NDVI and the interesting temporal resolution (16 days) of the MOD13Q1 dataset indeed offers the possibility of a very accurate bioclimatic mapping a robust capacity to detect changes in land cover and vegetation such applications will be presented. Some statistical methods will be presented with their applications to Sri Lanka.

Multi-disciplinary Experimental Research, Innovation and Commercialization – A Sri Lankan Perspective (Guest Speech)
Ranasinghe, Pathmasiri
“Research” is a common word in use with many varying meanings in the present world. However, when the term “experimental research” is referred, it carries a definite concept which is a key tool board of the modern research scientist. It can be simply explained as “a study that strictly adheres to a scientific research design, which includes a hypothesis, a variable that can be manipulated by the researcher, and variables that can be measured, calculated, and compared. The research scientist collects data and results which either support or reject the hypothesis”. This may be complex and tedious in execution than said, with respect to subjects and problems handled. However, clear, and deep knowledge in basic concepts of experimental research including identification and define of a research problem, hypothesis building, drawing of research objectives, experiment design, reliable execution of experiments and data collection, statistical data analysis, drawing conclusion and reporting, is a much-needed pre-requisites for successful completion of a research leading to new knowledge and innovations.
The research and innovations are being positioned on very high note in current global economic and political context, even we, as a nation have failed to pay sufficient attention so far. Even now, it will not be too late to understand the role and gravity of research, innovation, and commercialization in social and economic development, and try to bring up much needed attitude, cultural and policy enhancements in all sectors including school education, university, scientific community, and industry. In this scenario, here, I am trying to discuss some of my thoughts on the above areas with my learnings and experience in research, innovation, and their commercialization in local Sri Lankan conditions during past two decades.
