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"

Prudence Island is the 3rd largest island in Rhode Island. It is home to over 100 year round residents and is only accessible by boat or ferry. Most of the island is protected from development by the locally run Prudence Conservancy and the NOAA associated NBNERR. #NACIS #Map #Cartography #GIS

I just spilled my SmartWater on my leg like a big dummy. 🤦

#Nacis Map Gallery 1 #gischat

First time posting a map in the #NACIS map gallery. I forgot to grab a digital version before I left. It is a reference map of Prudence Island, Rhode Island. #gischat

Most maps shrink Hawaii into a compact box, but the archipelago actually sprawls 2,450 km across the Pacific. That's roughly NYC to Denver. This map shows the true extent — from Kure Atoll in the northwest to the Big Island in the southeast. vividmaps.com/hawaiian-arc...

Sometimes I have a feeler guess when I have no idea. I talked myself out of it, and of course it was the correct answer. 🤦‍♂️ chartle.cc

Does the news reflect what we die from?

I should have thought about this one a little bit longer. I was in the correct region though. chartle.cc

I thought resizing an existing map would be faster than creating a new one from scratch. I was very wrong.

I seem to get these on the first guess or not at all. 😂 chartle.cc

I don't know that I was thinking with some of these guesses. 😂 chartle.cc

Anyway seems not great that so many people with large platforms or in actual positions of power appear to have entirely lost their minds

This is surprising. I would have expected single parents to be one of the dominant groups based on the media. Married, no kids are basically flat. Single, no kids seems to be the big change in households. Overall, married households went from 74% to 47%.

Literally every other small business in Huntsville was "Rocket City" something when I grew up there. This man will take credit for anything.

Trump says that because he’s moving Space Command to “a locale called Huntsville, Alabama” which will *now* be forever known as “Rocket City.” He’s so powerful with these names, the bib from the marathon my dad ran there in the early 1980s has had this brand new nickname magically appear on it.

I was doing research on a RI hurricane in 1938 (unnamed) for one of my maps and came across this article. The eye of the storm landed in New Haven, CT, but RI was on the dirty side and got hit with a the storm surge. The photos help put it in perspective. www.providencejournal.com/picture-gall...

I just registered for my first Nacis conference. Now, I need to finish my map. 🗺️

For some reason, I thought it would be a good idea to start two more maps, as if the first one wasn't kicking my ass. This East TN tree cover map is for a GIS conference in a few weeks! #gis #gischat #cartography

Inspired by @imagineterrain.bsky.social recent maps using the FEMA NFIP dataset, I decided to make a map of my own. After hex binning the data, the spatial pattern more or less follows population centers, at least for the eastern portion of the US. I am still learning #QGIS! #GISChat #GIS

Some parts of the country see flood damage, over and over—I was wondering where. This series of maps shows the properties, covered under the National Flood Insurance Program, that have experienced repeated losses.

Making #QGIS progress. I am pretty happy with how these contours are turning out. I might try to make them a little smoother. However, they are much smoother than the initial run. But man, it is killing me not to jump back to #ArcPro and knock this map out. 😂

We seem hell bent on reliving the sins of the late 19th and early 20th centuries. I wonder how long it will take for these corporate coins to become company scrip. The article is paywalled, but we have been trending in this direction for a while.

I am looking for some help to organize the @ametsoc.org Applied Climatology conference next year at #AMS2026 Houston. It's our 30th annual conference (literally the number of years to compute a NOAA climate normal!) If you're interested, send me a DM! annual.ametsoc.org/2026/program...

In one of my GIS DB courses at JHU, I made an animated map of PM2.5 concentrations sampled at major lower 48 cities using R, FME, and ArcPro. Around the summer, you can see the 2023 Canadian wildfire smoke roll through the Midwest and the Northeast. #gis #gischat #geosky

Welp! I did a thing. I messed around and graduated. Of course, I thought I took a bunch of pics, when in fact I did not. 😂

Hello #gischat! Does anyone know how to create spot elevations for peak contours in #QGIS? I made the ones in the screenshot in ArcGIS Pro using the Topo Production tools. I am in the process of migrating over to QGIS since I will be losing all of my ArcPro licenses by the end of the summer.

Welp, after putting in an embarrassing number of hours into Civ 5 (I was stuck at 9999 hrs for years), I managed to keep it off my new computer last fall. Last night, Civ 6 was on sale for $5, and I feel like I just ruined my life for $5. 😂

I mapped payday lenders in my county for my associates GIS capstone project. Many of them were located in middle and lower-middle income neighborhoods. This tracked with Baradaran's book, How The Other Half Banks. It is crazy that they can sue after trapping people in these predatory loans.

I am a big fan of these Wurman Dot style maps, even if I think they are borderline unreadable. 😅
