Linked Brazilian Amazon Rainforest

Tomi Kauppinen

Open Science needs Open Data to maximize the transparency, reproducibility and reuse of scientific efforts. An example of a high demand for data is the research about climate change, for example about the role of deforestation in it.

Deforestation and its related phenomena such as market prices of agricultural products form together a complex system. To analyze and model this kind of a complex environmental and societal system there is an urgent need to share and publish research data. This is needed because it enables other researchers to interconnect their data to the published ones.  This allows for the combination of all of the resulting linked data to be used as a source for the analysis of the whole complex system, and not just a subset of all the interesting operations and processes of the system.

Linked Brazilian Amazon Rainforest Data is such a dataset that is openly available for anyone to use for non-commercial research. The data was produced as a joint effort by the Institute for Geoinformatics, University of Muenster, Germany and the National Institute for Space Research (INPE) in Brazil.

The data can be accessed in a Linked Data fashion via a SPARQL-endpoint, and via dereferenciable URIs. The data consists of 8250 cells—each of size of 25 km * 25 km—capturing the observations of deforestation in the Brazilian Amazon Rainforest and a number of related and relevant variables. This spatiotemporal  deforestation data was created using a number of  aggregation methods from different sources. The data covers  the whole Brazilian Amazon Rainforest.

Easiest way for time-being of learning how to utilize the data is to go through a tutorial having examples of accessing, analyzing and visualizing this spatiotemporal data using SPARQL query language in R statistical computing environment. Below is an example visualization that one can create by following the instructions of that tutorial.
