  4. I think that VPD has to protect the privacy of individuals, so they use 10xx instead of real addresses. Redaction of information can help cartographers highlight and emphasize the most important features and data on a map by removing distracting details, leading to a clearer representation of geographic information. Also, it might be simpler to understand, so people without geographic knowledge can understand the data. One drawback is that redacted maps may not provide a complete view of a geographical area, making them less useful for planning, research, or decision-making. Another drawback is that the data given for a location is basically just a street, which can be anywhere on that street. However, I did notice there is latitude and longitude, which can tell us exactly the right location. 
  5. Actually, there are more effective ways to visualize our bike theft data. There are way too many points, and if it was a static map, you couldn’t see where each point is located. The symbols used to represent the bike theft are way too large. 
  6. A base map is a fundamental representation of geographical and spatial information that usually includes essential geographical features like landforms (e.g., mountains, rivers), bodies of water (e.g., lakes, oceans), roads, railways, and political boundaries (e.g., country, state, and municipal borders). Interactive maps often allow users to overlay multiple layers of data onto the base map so they are able to customize the map to their specific needs. Users can toggle different layers on and off, adjust transparency, and combine various datasets to create a better understanding. The base map data can also be zoomed in to see the data at a larger scale.

  8. Hex codes are a hexadecimal format for identifying colors. Each letter or number can change the color from one hue to another. The hex code for the color blue is 0000FF.
  9. numbers = c(1, 2, 3, 4, 5, 6, 7, 8) or  numbers = list(1,2,3,4,5,6,7,8)

  11.  I think that the map that I created serves the purpose of displaying bike theft in Vancouver. Some things that I would have liked to change would be the ability to update the map in real-time. I think that would make the map more useful for users to see where bikes are being stolen in the present day. Also, I would have liked to include data on how the bike was stolen. For example, the lock being cut or the person just being absent-minded and leaving the bike unlocked. I would also like to know whether the data states that the whole bike was stolen or just the wheels and seat, as I see that more common around the UBC campus.
