Abstract
Analysis of multidimensional and time series data is useful and pertinent to several different applications, being a challenge due to the volume and complexity of the data. A possible approach for analysis of this kind of data is to use clustering algorithms to reduce the dimensionality of the data. This paper presents a tool for clustering and visualization of data, called ggsom, which uses a technique for data dimensionality reduction through projection of the data in a smaller number of dimensions by the Kohonen’s Self-Organizing Map. The tool is evaluated with data from time series of vegetation coverage from Bahia
state.
