This study’s primary goal is to highlight the importance of accessible information on trails in the Tijuca National Park in Rio de Janeiro, Brazil to show the safest regions available for visitors. Proximal interpolation was used to calculate the values for homicides in each neighborhood near the park. The homicide rate was not distributed evenly. This method allowed lines that split in midpoint locations to be connected to each point value to form an enclosed area. First, I separated all data starting with existing layers as the division of municipalities or neighborhoods of Rio. A polygon layer outlines the slums surrounding the park’s adjacent areas. The next step converted homicide data from a spreadsheet to a feature class that can be represented by either points or gradual symbols on the map. A raster file containing peaks and the park’s main attraction helped create a feature class polygon representing the park boundary. These points also helped determine what trails from OpenStreet maps can be considered official. I manually drew the trails by using vector points. After analyzing the data, a question was raised about the inconsistency of data available to visitors. This highlights the infamous crime rate in Rio which can potentially generate a low number of visitors in some sectors of the Tijuca National Park.
