Arizona Joy Plot Map Testing out another method. Instead of applying the gradient across the entire feature layer, I applied a gradient to each individual plot line. This gives the plot lines a more 3D like effect. This is still a work in progress. #gis #qgis #cartography #maps

Happy Solstice and first official day of winter. More daylight each day now and spring is not far away.

Solstice on a Spinning Earth apod.nasa.gov/apod/ap25122... Can you tell that today is a solstice by the tilt of the Earth? Yes. At a solstice, the Earth's terminator -- the dividing line between night and day -- is tilted the most.

Man, I'm done with the days getting shorter! I am talking to MANAGEMENT. I will GET RESULTS. If the days get longer here on out, you'll know who to thank.

Happy winter solstice. 📊

Today is the Winter Solstice, the longest night of the year for most of us living between the Equator and the Arctic Circle. The duration varies by latitude. Those living in the Arctic are experiencing Polar Night, which may have begun weeks ago! Blog antonioantoine.com/2025/12/17/t...

Got my #NACIS Christmas tree ornament up! I think it is the only mappy ornament I have and I happened to win it at the 2025 conference.

I am thinking about doing a state-level run of Joy Plot maps. I do think Virginia may have set the bar a little high. It looks like a mountain emerging from the fog. #cartography #maps #qgis #gis

If you enjoy both #RhodeIsland and #rivers, stop by The Map Center (@mapcenter.com) to check out (and maybe buy?) this poster I designed for them, showing the state's streams in the style of a transit network map.

The #30DayMapChallenge is a wrap! I made a map quilt of my favorite Rhode Island maps from the challenge. I had to resize a few of them to get them all to line up. Had I planned this in advance, I would have alternated between light and dark maps. #cartography

Dark mode maps are attractive & engaging, but present design difficulties. It’s harder for us to parse light on dark than dark on light, and the way we interpret variation in lightness as differences in transparency compounds the difficulty. 📊🗺️🎨 From: www.bloomberg.com/graphics/202...

I got maps to make, but the second shingles shot is kicking my ass. 🤒 Vaccines usually are pretty mild for me. I don't have Spotify, but YouTube Music is trying to embarrass me with my listening habits of 2024. I am not sure how Draggin Around was my top song. lol. Everything else makes sense.

Introduce yourself with five cars you've owned. Judging by the other responses, I might be one of the few "car guys" on here. 2003 Subaru WRX (Current) 2005 Subaru WRX STI 2009 Subaru WRX 2003 Audi A4 2005 Mustang I clearly have a thing for the 2000s era. 😂

Day 29 - Raster Rhode Island 24K Topo Maps I have wanted to make a version of this map for some years now. TopoView was a big help in downloading the 24k topos. Clipping and stitching the 38 topos was a pita even with batch processing. I crashed QGIS a few times. lol #30DayMapChallenge

Day 28 - Black The Longest Nights (2025) Polar night (+24 hr night) occurs just beyond the Arctic Circle. This is due to the Earth's gravitational pull on light. The ramp up from just beyond the Arctic Circle 67.4°N (24 hrs) to 67.5°N (11 days) is wild. #30DayMapChallenge

Day 27 - Boundaries EST States & Provinces How many states and provinces share the same time zone as Rhode Island? #30DayMapChallenge

Day 26 - Transport Rhode Island Bike Lanes & Routes I am not super happy with this one (don't hate either). I think it needs to bake for a few more hours. Maybe even a total redo. However, I am running low on time and creative energy. And this isn't my normal lane, lol. #30DayMapChallenge

Day 25 - Hexagons Rhode Island Dating Age Population Distribution I have been thinking about making a national version of this map for some time now. The hue indicates whether a cell has more men or women (age 20-39). The hex size shows the cell pop density per 1 km (0.6 mi). #30DayMapChallenge

#30DayMapChallenge: Day 23's theme was "Process", here are several interesting spatial tutorials that came across my feeds ⬇️ 1/ #cartography #GIS #remotesensing #GIStutorials #GISChat

Day 24 - Toponymy Rhode Island Indigenous Toponymy This map shows the places (cities, towns, and villages) in Rhode Island named after Indigenous people, places, or things, along with their meanings. #30DayMapChallenge

Day 23 - Process Create a Joy Plot Map in QGIS I created a workflow for creating a Joy Plot Map in QGIS. I plan on adding more workflows or tutorials in the future. antonioantoine.com/2025/11/23/c... #30DayMapChallenge

Day 22 - Natural Earth (NE) Antarctica Taking a small break from Rhode Island today for a map of Antarctica. Most NE data is intended for medium to small-scale maps, so I wanted a subject area that was a little larger. All layers are vector data from NE. #30DayMapChallenge

Day 21 - Icon Rhode Island Public Libraries Here are the Public Libraries across Rhode Island. The symbol is from the @nounproject.bsky.social, which is probably one of the best subscriptions I have. The symbols are graduated by square footage. #30DayMapChallenge

Day 20 - Water Narragansett Bay Watershed 10 Days to go! I am starting to feel a little repetitive. 😰 The bathymetry saved this one. Almost all of Rhode Island is in the Narragansett Bay Watershed. I think I will expand this one into a large format map one day. #30DayMapChallenge

Mama, I made it! 😁🗺️ #gischat

Day 19 - Projections Rhode Island Projections All caught up! I wanted to compare a few projections I have tried with my Rhode Island maps. These projections are centered on Providence, similar to @kennethkhw.bsky.social map. #30DayMapChallenge

Day 18 - Out of This World Sea of Tranquility Apollo Lunar Landings Technically, there is just the one Apollo mission in the Mare Tranquilitus, but the others are in the extent. Fun fact: I grew up in the Rocket City, and I was born on the anniversary of a lunar landing. #30DayMapChallenge

Day 17 - A New Tool Rhode Island Hillshade I am a day or two behind now. I finally got #Rayshader installed; it was a whole ordeal. This map is nothing crazy. Just a hillshade of Rhode Island that I annotated in #AffinityDesigner. #30DayMapChallenge

Now with more accuracy! 😅 I goofed and got my meters and feet mixed up. Thanks to @bboucek.bsky.social for catching that! Normally, I reproject my DEM so I don't have to do the conversion later. I forgot this time. The highest point in RI is still Jerimoth Hill at 803ft (244m). #30DayMapChallenge

Day 16 - Cell Nearest Hill in Rhode Island The Ocean State is pretty flat, at least to someone who has lived in Appalachia for most of his life. The highest point is 244 ft. I sampled the elevation from a DEM & I mapped the nearest "hill" for anyone looking for a potential view. #30DayMapChallenge

Day 15 - Fire Rhode Island Wildfire Risk I swear I am not making the same forest map over and over again. 😂 Overall, RI has a very low wildfire risk. It is probably no surprise that the forested areas are at higher risk. The risk also increases from north to south. #30DayMapChallenge

Day 14 - OpenStreetMap Rhode Island Forests Rhode Island's OSM forest coverage is very good. This source may be an option for my other maps. I spent a few hours creating a map similar to the forest types map from day 2 before changing directions to a more minimalist design. #30DayMapChallenge

Day 13 - 10 Minute Map RI Passenger Vessel Routes in July This is my third 30Day challenge, and I always flub the 10 min challenge. My eyes are always bigger than my stomach. 😂 I wanted more of a glow effect, but that ate up all of my time. #30DayMapChallenge

Day 12 - Map from 2125 SLR in Rhode Island Part of my MS research, I studied the impact of SLR on bldgs in coastal LA. SLR is rising faster in the Gulf than anywhere else in the US. While the RI SLR extent is not as bad as LAs, the population density is higher. #30DayMapChallenge

Baby #aurora in Knoxville, TN.

Day 11 - Minimal Rhode Island Elevation Joy Plot Map I made a Joy Plot map years ago in ArcPro, but I am using QGIS these days, so I figured this would be a great time to learn a new workflow. I will be posting the workflow on Day 23 - Process. #30DayMapChallenge

Day 10 - Air Rhode Island Annual Mean Wind Speed 🍃 RI coastlines, urban areas, and lakes are pretty windy at the surface level. Prudence Island was a little surprising, given the stories from early settlers. Poor Block Island, though (probably my symbology). #30DayMapChallenge

Day 8 - Urban Rhode Island Urban Land Use This is my first time using OSM data for a land use map. The data seems pretty complete, a near mirror of my Forest Types map. Hopefully, Knoxville will get to this level of coverage one day. #30DayMapChallenge

Day 7 - Accessibility Walking Times from the Independent Man The Independent Man is a gold-plated bronze statue on top of the Rhode Island State House, located in Providence, RI. This is an isochrone map that I made more complicated by symbolizing the roads by color and weight. #30DayMapChallenge

Day 6 - Dimensions Rhode Island Elevation Contours I tried using the 2.5D tools in QGIS for this one, but I didn't like how they turned out. After creating the color ramp, I added the shadows in Affinity Designer. This gave the contours a 3D effect. #30DayMapChallenge

Day 5 - Earth The Forests of Rhode Island Back to Rhode Island! This is an extension of my East TN Forests map. I may make a state-level series out of these. (Sorry Block Island, I had to clip you out of this one.) #30DayMapChallenge

Day 4 - My Data RSCC Tree Map A couple of summers ago, RSCC students Kasey Byrne and JD Burnette helped me map the trees at the Oak Ridge campus. They logged the tree species, heights, diameters, canopy, and general health. I digitized the other campus features. #30DayMapChallenge

If anyone needs a place to start for data for #30DayMapChallenge, I present my Semiannual Plug for growing collection of carto sources. It's 15 years old, and I've done minor link checks, but am hoping to prioritize cleaning links next summer. sites.google.com/view/geovisu...

Day 3 - Polygons The Native Lands in Rhode Island One of my carto goals is to make a big map of the native lands in the US. Judging by my experience with this RI map, I may have to map by region or state level. Lots of boundaries overlap, making it difficult to show them all. #30DayMapChallenge

Day 2 - Lines Rhode Island Historical Hurricanes (1851-2024) Someone made a map of hurricane tracks over FL for a previous 30 Day challenge. I don't remember who it was, and I can't find their info. It was on the old site. Either way, that map inspired me to make one for RI. #30DayMapChallenge

Day 1 - Points Rhode Island Lighthouses Most of my maps will be about Rhode Island. A good way for me to learn about a place (and find datasets) is to try to create a map of a thing. #30DayMapChallenge

Hey #gischat, is anyone else having issues accessing data from The National Map or LidarExplorer? Whenever I run a search, TNM says "too many records", and LE starts to search, then stops. I'm guessing the issues have something to do with the shutdown.

I am in Murfreesboro, TN today for another TNGIC forum. Of course, I had to bring a map. #gischat #gis #cartography

Wild! This NOAA video shows how quickly fossil fuel CO2 can accumulate. It shows daily fossil CO2 over a 2 year period (2011-2012), starting with a concentration of *Zero*: "By the end of 2012, the entire Northern Hemisphere is red, illustrating a total accumulation of about 9 to 10 ppm of CO2"
