GIS Programming Peer Review 2

Peer Review 2
The work I chose to review incorporates an original idea of finding a solution to a problem that will arise in the future with the inevitable eruption of Indonesian volcanoes. Bear-Crozier, Kartadinata, Heriwaseso, and Nielsen’s (2012) application involves a Python based script used to simplify the process of installing and running a core prediction model. The model allows for analysis and prediction of volcanic ash fall following an eruption. The product was developed in cooperation with three major GIS agencies
The paper makes a strong case for the need for the solution. The hazards are clearly explained and show with an example how the research will help scientists predict the ash flow of future eruptions in the Indonesian region. The example itself is a great strength of the research showing that the developed script is in fact executable and provides valid analysis tools for scientists to use when studying the region. In the event that a volcanic natural disaster occurs in the region products will be available to provide the necessary evacuations and notifications. This was not possible with the previous data and models provided.
            One of the few weaknesses of the research is the usage of acronyms. The effort improves as the reader continues through the document, but at the beginning there are a few instances of acronyms being used that are research specific and everyday users would not understand the meaning. Descriptions are provided later in the body of the paper, but few instances at the start could leave the readers confused as to what is being discussed. This is only a minor readability flaw and would not affect the overall understanding of the research. The only other weakness I discovered is the fact that there is no new science developed in the research. The paper definitely describes a solution to a problem, but the solution is a Python based script that simplifies installation and running of a core model. There is definitely science involved in the programming of the package for running the core model (FALL3D). The script that the team developed is simply an adaptation that will make the process of volcanic ash fall analysis more streamlined. This is a weakness that does not take away from the research, but it does disqualify it as developmental in my opinion.
            The research is clearly laid out in chronological order how the study came about and who worked together to accomplish the results. The collaboration of three GIS departments shows the checks and validation that went on to achieve valuable and relevant results. If a single organization carried out the work then the results could be biased or not geared toward a universal solution. In this case the research methods are transparent and follow all scientific guidelines.
The single thing I liked most about the research is the use of illustrations. Being a visual learner the illustrations greatly increased my understanding of the study location and overall results of the research. There are many illustrations within the document that visually depict the processes and results of the study. The amount of illustrations is definitely a positive thing, but a few of the illustrations could have better labeling geared toward non-GIS familiar users. Some illustrations used an advanced or system specific labeling method that could make it confusing to some readers. I would have utilized a more “Plain English” approach to describing the technical illustrations.    
In wrapping up the study Bear-Crozier et al. (2012) conclude that the newly created process does in fact generate a usable product and proves the point with an example. I find this to be very important to the work because it shows the success of the research and how the accomplishments work in the analysis of future eruptions.
