1 00:00:00,060 --> 00:00:08,429 Hi my name is Eleanor Lutz and I like to use art and data visualization ah to try 2 00:00:08,429 --> 00:00:13,740 and take scientific topics and share them with the general public, so my most 3 00:00:13,740 --> 00:00:21,539 recent project was a series of about ten different maps of astronomy data taken 4 00:00:21,539 --> 00:00:27,900 from open sources like NASA and the USGS so I'd like to talk a little about some 5 00:00:27,900 --> 00:00:31,380 of the things I learned from making these maps and then some of the design 6 00:00:31,380 --> 00:00:37,110 decisions behind each one, so to give you a bit of background when I share these 7 00:00:37,110 --> 00:00:40,770 maps all of the code is open sourced on github 8 00:00:40,770 --> 00:00:46,410 with tutorials so that anybody who wants can make the maps themselves. I also have 9 00:00:46,410 --> 00:00:51,059 the maps available as posters and the people who tend to generally use them 10 00:00:51,059 --> 00:00:55,410 are people who have young kids or our teachers and classrooms so that's really 11 00:00:55,410 --> 00:01:02,160 the kind of audience that I'm designing for, this first map shows the orbit paths 12 00:01:02,160 --> 00:01:09,540 of about 18,000 asteroids in the solar system, so this map was probably the 13 00:01:09,540 --> 00:01:13,590 most difficult one for me because I needed to pull together data from about 14 00:01:13,590 --> 00:01:20,340 five different open data sources and put them together and the the question I 15 00:01:20,340 --> 00:01:25,380 really tried to answer while making this map was what was the the general message 16 00:01:25,380 --> 00:01:32,340 I wanted to get across to these children or the general public and for me what 17 00:01:32,340 --> 00:01:36,259 was the most awesome thing about this data was just that there are so many 18 00:01:36,259 --> 00:01:41,640 asteroids all over the solar system and I'm not actually a space scientist so 19 00:01:41,640 --> 00:01:46,110 this is something that was really surprising to me so I decided to use 20 00:01:46,110 --> 00:01:51,840 design decisions that would really emphasize that point so for example I'm 21 00:01:51,840 --> 00:01:57,180 showing you all of the orbits here on a logarithmic scale with most of the map 22 00:01:57,180 --> 00:02:02,490 focus on the first billion kilometers from the Sun and this was a design 23 00:02:02,490 --> 00:02:07,200 choice that let me include everything to the boundaries of the solar system but 24 00:02:07,200 --> 00:02:12,510 still leave enough space to see just how many asteroids are in the inner 25 00:02:12,510 --> 00:02:14,930 areas 26 00:02:19,319 --> 00:02:26,489 okay so for other projects I had to do much less data wrangling so this is a 27 00:02:26,489 --> 00:02:33,500 geologic map of Mars some of you might recognize the data from the USGS map 28 00:02:33,500 --> 00:02:39,780 which basically had all the data I'm showing here already laid out and 29 00:02:39,780 --> 00:02:46,019 organized the main design choices I did here was really to work with the 30 00:02:46,019 --> 00:02:51,239 language in the map the original map was I think intended for scientific 31 00:02:51,239 --> 00:02:56,989 audiences so the labeling and the colors were very difficult to understand 32 00:02:56,989 --> 00:03:02,549 especially for young audiences so in the bottom here I've really shortened all 33 00:03:02,549 --> 00:03:07,109 the descriptions and tried to use vocabulary that everybody could 34 00:03:07,109 --> 00:03:18,030 understand. I also changed the colors of the map, so here's a zoomed in version 35 00:03:18,030 --> 00:03:22,560 I've decided to really emphasize the volcanic geologic region so I'm making 36 00:03:22,560 --> 00:03:28,019 them a really bright red and then also to emphasize the difference between the 37 00:03:28,019 --> 00:03:32,180 northern and southern hemispheres by putting slightly different color schemes 38 00:03:32,180 --> 00:03:38,010 so I want to point out that sometimes these design decisions don't necessarily 39 00:03:38,010 --> 00:03:43,199 make the map more legible I think some of the volcanic regions in particular 40 00:03:43,199 --> 00:03:49,229 can be a little hard to read but because these maps weren't for a scientific 41 00:03:49,229 --> 00:03:55,409 purpose I could make design decisions that were a little more creative and 42 00:03:55,409 --> 00:04:01,400 that emphasized the volcanoes or these other features the planet 43 00:04:05,380 --> 00:04:13,260 sometimes I needed to do a little more simplification of the data to have the 44 00:04:13,260 --> 00:04:18,900 data fit and look well at the size that I was going for so this is a geologic 45 00:04:18,900 --> 00:04:25,020 map of the moon the difficulty here was that because the data for the moon was 46 00:04:25,020 --> 00:04:30,930 much more detailed the geologic features were a lot finer and many of them 47 00:04:30,930 --> 00:04:35,160 couldn't actually be seen at the scale that I was showing at these posters 48 00:04:35,160 --> 00:04:41,880 these clusters size, so when I went through the data I that many of the 49 00:04:41,880 --> 00:04:49,410 smaller geologic features were actually different ages of the same material and 50 00:04:49,410 --> 00:04:57,090 this was causing a lot of noise in areas that had been sampled many times, so what 51 00:04:57,090 --> 00:05:01,680 I decided to do for this map was to simplify it to a level where you could 52 00:05:01,680 --> 00:05:07,140 see individual geologic features, so this map doesn't actually include the 53 00:05:07,140 --> 00:05:12,450 different ages of the materia,l it's combined the material the same type of 54 00:05:12,450 --> 00:05:17,420 geologic material for many different ages 55 00:05:26,060 --> 00:05:31,730 okay, I also had to combine I think six different data sets for this moon 56 00:05:31,730 --> 00:05:35,840 geology map, you can actually see the boundaries here where some of the data 57 00:05:35,840 --> 00:05:41,120 sources don't agree with each other, so that was a part where in the previous 58 00:05:41,120 --> 00:05:47,240 map I also decided to include the different data sources as a reference 59 00:05:47,240 --> 00:05:50,160 for why those differences existed 60 00:05:56,120 --> 00:06:01,490 okay I also designed a series of topographic maps of the rocky planets 61 00:06:01,490 --> 00:06:04,729 and the moon so for these maps I use the digital 62 00:06:04,729 --> 00:06:10,639 elevation model from the USGS as well as a database of names that I could 63 00:06:10,639 --> 00:06:16,370 download and plot onto each of these maps in Python, so one of the challenges 64 00:06:16,370 --> 00:06:21,650 of making topographic maps for space was that I found it was very difficult to 65 00:06:21,650 --> 00:06:25,760 kind of understand the scale of the planet because there are no oceans or 66 00:06:25,760 --> 00:06:32,540 other large differences in the in the surface, so what I try to do with these 67 00:06:32,540 --> 00:06:39,470 maps is use a color scale that was very variable from the the lowest parts here 68 00:06:39,470 --> 00:06:42,050 in Navy to the highest parts of the planet and 69 00:06:42,050 --> 00:06:51,500 orange and yellow and making these double color decisions for each of the 70 00:06:51,500 --> 00:06:56,180 planets I think really helped emphasize the scale of the planet by adding a 71 00:06:56,180 --> 00:06:59,840 little more interest in by helping differentiate between the different 72 00:06:59,840 --> 00:07:02,050 elevations 73 00:07:05,670 --> 00:07:10,620 I also made a map of the earth so if you look at this online it's actually 74 00:07:10,620 --> 00:07:14,880 animated so that each of the frames shows the Arctic ice for that particular 75 00:07:14,880 --> 00:07:19,580 month of the year and this is using blue marble data from NASA 76 00:07:23,040 --> 00:07:25,280 okay and this 77 00:07:25,290 --> 00:07:30,180 final set of maps I want to talk about is a map of the constellations as seen 78 00:07:30,180 --> 00:07:36,330 from Earth, so this was one of my favorite maps to work on because there's 79 00:07:36,330 --> 00:07:41,160 just a huge amount of data available, here I've already limited the data I'm 80 00:07:41,160 --> 00:07:47,550 showing to the 8,000 or so stars you can actually see from Earth but there's 81 00:07:47,550 --> 00:07:53,760 still a lot of data a lot of information about the size of the stars and as well 82 00:07:53,760 --> 00:08:00,210 as the constellations and the names of each star this map is actually part of a 83 00:08:00,210 --> 00:08:07,350 series, so here is just the you know the scientific data without the labels and 84 00:08:07,350 --> 00:08:14,190 the lines that people have added and what I realized here was that these 85 00:08:14,190 --> 00:08:20,700 constellations, come from many different cultures so here I'm showing you the 86 00:08:20,700 --> 00:08:26,400 same stars but in this map I'm showing also the constellations from about 30 87 00:08:26,400 --> 00:08:33,599 different cultures or civilizations from around the world each color here is data 88 00:08:33,599 --> 00:08:39,960 from a different culture this is from an open database called Stellarium and what 89 00:08:39,960 --> 00:08:45,240 I really like about this map is that even though it's kind of a tangled mess 90 00:08:45,240 --> 00:08:50,850 of lines you can see that some stars are really popular the ones the large ones 91 00:08:50,850 --> 00:08:57,420 circled with large outlines with a most popular but some constellations are also 92 00:08:57,420 --> 00:09:04,560 very unique so the stars outlined in an outline with just one cultures color is 93 00:09:04,560 --> 00:09:11,220 not used by any other culture in this database so I really enjoyed this 94 00:09:11,220 --> 00:09:16,860 project in particular because I was able to combine scientific data from this 95 00:09:16,860 --> 00:09:21,280 large database with cultural data and kind of 96 00:09:21,280 --> 00:09:25,960 the human history of how we've been looking at stars and working with 97 00:09:25,960 --> 00:09:33,430 astronomy for many hundreds and thousands of years so as I said again 98 00:09:33,430 --> 00:09:37,990 all of this code is available open source please feel free to find me 99 00:09:37,990 --> 00:09:42,430 afterwards if you're interested in learning more about the project and 100 00:09:42,430 --> 00:09:46,480 thank you so much for everyone for listening and for NASA and AGU for 101 00:09:46,480 --> 00:09:49,200 letting me come here
