![]() Next, I eliminated all the points that were not on land. (Armeleon used 791 miles as his distance, but according to Wikipedia, "The longest straight-line distance is from the northwest corner of the panhandle to the Rio Grande river just below Brownsville, 801 miles". Then, for each grid point, I kept the pairing with the minimum distance to the border, and finally limited it to just the dots within 1 tex. I did this by taking every dot in the grid, and pairing it up with every point along the Texas border (using an SQL join), and then using the geodist() function to calculate the distance between every grid dot and every point along the Texas border. I then used brute force to determine which of the dots were within "1 tex" (801 miles) of the Texas border. I annotated these dots behind the map, and then made all the map areas transparent except for Texas (which I made solid yellow). First, I looped through the nearby latitudes and longitudes, and created a grid of dots. I thought it would be a fun challenge to see if I could create a similar map using our SAS software, so I gave it a shot. The map visually caught my attention, and I found the topic a bit intriguing (having lived in Texas when I worked at Shell Oil's research center long ago). ![]() I had seen it a few places online, and I believe it was created by reddit user Armeleon. More on that later - but first, here's a picture of my friend Jennifer posing beside a rather large handgun in Texas (how much more 'Texas' can you get, eh?!?)Īnd now, let's create a cool graph! Below is the original graph that gave me the idea. Everything's big in Texas - at least that's what they say! Therefore let's have a bit of graphical fun, and use Texas as a unit of measure (let's call it a 'tex').
