Adding Arts Afield Sites

[cathyleee]

Based on Professor Bertone-Johnson's recommendation, we will take into account the proximity of any Arts Afield Sites to the trails. To do this, I think we need to use st_buffer(). We can create a buffer of maybe 300m around each Arts Afield Site, and if the trails intersect with those buffers, then they are close to an Arts Afield Site. I am not sure about the exact syntax for this, but I think st_buffer() would be the most suitable function.

We have created a 50m buffer around each Arts Afield Site, as we thought that 50m was a reasonable maximum possible distance that a site would be visible from the trail. However, 2 of the sites have the name "TREE REMOVE?". We are unsure what this means (compared to the other names of the other sites, which sound more like landmarks), and have contacted Professor Bertone-Johnson for clarification. Below is a screencap of what the plot now looks like with the Arts Afield Sites and their buffers:

We are going to change the colour of either the buffer or the "Easy" trail, since they are currently both blue, and could be potentially confusing.

Next, we will calculate the intersection of the Arts Afield Site buffers with the trails.

We calculated the intersection of the Arts Afield Site buffers with the trails. What this data represents / the question this data answers: How many Arts Afield Sites are within viewing distance of each trail?

The maximum number of intersections was 4, and the minimum is 0. Possible range:

• 0: None
• 1-2: Sparse
• 3-4: Rich

We will colour code according to these categories and create a new plot showing which trails have Arts Afield Site buffers within viewing distance (and will therefore be suitable for humanities / studio art classes and organisations).
