Hope and GIS

I am grateful for the opportunities, responsibilities, and guidance I have received.

I am grateful for having a fair and competent committee.

This academic year, beyond writing in a daily basis, it is the year of synthesizing what I observe in the landscape through metrics in order to develop indices or measurements which will allow us to contribute of taking care of Our Common Home. In my case, it is land management, river management, and it has an influence on water, air quality and climate, and on so on the aquatic and terrestrial wildlife and human life that happen on it.

It is the year to understand better about artificial intelligence. The word might scare many or motivate others. Well in my applications or development, it means modeling physical process in the landscape through a computer. As many of us use Google maps or Google Earth, which provides map cartography or satellite images for any purpose that we might be using. Likely, for finding an address. Well, that it is the simple example of the use of a static map. For my purposes the elevation of a point, which actually is a cell in the map is important. The soil taxonomy in that cell is important. The land cover in that cell is important, which for example can be a road, a forest, another vegetated area, bare soil, etc. Location of rivers, lakes, floodplains, wetlands, are also important. So I can use the satellite images and train the computer to help to classify the landcover in a large extend. People have also created computer models which based on information points on contour lines generates a Digital Elevation Model of the landscape. It represents visually what in a see or not see in the real landscape, now in the computer in a mesh of cells. Then one can start flowing and modeling water or sediment in the rivers in that mesh. Modeling, for example, changes on soil erosion due to changes of the land-use or land cover. And many other applications.

It is the year of learning, developing and implementing GIS and Remote Sensing to my field of environmental studies.
