Selected Topics in Geoinformatics


Crowdsourcing a noise map

  What is the difference between sound and noise ?! Can we trust the data which was obtained from the open sources ?! In this lecture, I found answers to these questions.

    I found out that there is a project called Noise Tube. The Noise Tube project proposes a participative approach for monitoring noise pollution by involving the general public. 

   On www.noisetube.net website there is a map with the cities which have data about the noise in the city. In the July I will go to Kazakhstan, planning to add some data about noise in Almaty.


Integration and interpolation of point-cloud data (sonar) for semi-automated extraction of 3D underwater elevation models

   This project is a vivid example of the possibility of applying GIS technology in various fields of human being . In the project has been used Safe Software Feature Manipulation Engine (FME), which I first heard. It was very interesting to learn about a new software product for me. Also, the topic of interpolation was explained in detail. Advantages and disadvantages of each interpolation kind. The rapid entry into each topic really helped catch a course of action.


Findings in Communicating (Spatio-Temporal) Web Maps

  Creating a good user interface is a complex work. Since a lot depends on user's first impression. A detailed description of the color models and colors combination helped me a lot.  I am cartographer, therefore the combination of colors is sometimes a sore point for me. Gestalt principles are very interesting, and I think they are applicable to many aspects of our live. The web-site  www.ColorBrewer2.org is a godsend for anyone who is planning to create a good map.

Climate change and vulnerabilityto vector-borne diseases

Modeled surfaces of malaria risk, including the EIR and malaria vulnerability

  Vector-borne disease is the term commonly used to describe an illness caused by an infectious microbe that is transmitted to to people by blood-sucking arthropods. This problem is common in many African and Latin American countries. Mapping and analysis of latent phenomenon is very difficult task. 


Transit times of baseflowin New Zealand rivers

  Since I do not go deep in hydrology, the lecture was slightly hard for me. The ability to recognize the age of the river water by a mix of numerical modelling and tracer techniques are an unusual solution.  In my opinion, this topic is very extensive and involves a large amount of research. At the end of this lecture, I realized, that I need to learn more about hydrology :)

GPS trajectories and automobile energy use

 The movement analysis is a complex activity. This project uses movement analysis to determine the places in Salzburg with high automotive energy consumption. As a result spatio-temporal map  of energy consumption of automobile traffic in Salzburg was presented.  I think this method would be useful for the large cities, where Number of cars is much higher. 


Geospatial Approach for Mitigating Natural (Flood) Hazards in the Himalayas

  The flooding, hurricanes, earthquakes and other natural disasters were still one of the main topics for humanity. These natural disasters lead to the greatest loss of people. This project with the help of  TERRA-MODIS CWC and TRMM precipitation data  and GIS software can help in developing flood alert and warning system. Monitoring the movements of clouds followed by precipitation is a effective method of detecting possible flood areas.


Spatio-Temporal Pattern of Aerosols in India

   Climate Change is a big problem at the moment. One of the factor of this is an aerosol. Aerosols are colloids of fine particles suspended in the air that come from natural sources or man-made activity and are known to impact the climate and human health. According to the maps that presented  Dr. Shahnawaz obviously clear that for India, this problem is one of the most important. With the presented method, can be determined changes in the quantity, also the movement of aerosol in study area.

Forest succession mapping with Airborne LiDAR

   Before this lecture, I only heard about the problem of deforestation. I was happy to know that in Poland there is no problem with forest))) The LiDAR system nowadays is very popular in many research fields. It gives an accurate assessment about state of forests in the study area. 


GIS for DEVELOPMENT

   Volunteered geographic information (VGI) is the harnessing of tools to create, assemble, and disseminate geographic data provided voluntarily by individuals (Goodchild, 2007). Some examples of this phenomenon are WikiMapia, OpenStreetMap, and Google Map Maker. VGI can also be seen as an extension of critical and participatory approaches to geographic information systems and as a specific concern within online or web credibility.These sites provide general base map information and allow users to create their own content by marking locations where various events occurred or certain features exist, but aren’t already shown on the base map.
