Today is Phelan-McDermid Syndrome awarness day. It is a rare genetic disorder, which present a lot of different daily challenges especially around communication. My daughter was diagnosed about 3 years ago and knowing has answered some questions but left many others. https://pmsf.org

Since starting back to school after teaching a long while, I am realizing just how much good teaching pedagogy means to me. I have focused a lot over the years improving my pedagogy. It is so frustrating to have professors that struggle with the basics. I can see just how much that impacts learning.

Disasters have cumulative impacts that are often greater than the sum of the individual events. In the Gulf States, EVERY county has had at least 3 federally declared disasters since Hurricane Katrina, and some have had upwards of 20.

One of the reasons FEMA's Katrina response was so disorganized was that they'd recently been reorganized when the federal government created DHS after 9/11. Experts are saying a similar brain drain is happening now

Last night I posted something personal and somewhat vulnerable. I thank everyone who replied. It made me feel much better connected and just not alone in what I was feeling. In reflection, I do not know if impostor syndrome was the right term, but your replies did give some guidance. Thank you!

I have a serious question to those who have gone back to school after being a working professional for many years. How did you get over the imposter syndrome or feelings like you did not belong? I have finished my first year of my PhD and while most things are going well. 1/2

Anyone curious about the ground resolving distance of Maxar (maybe Airbus) ultra-high-resolution satellites? Use this calibration target near Batou, China to find out! Screen capture from Google Maps: maps.app.goo.gl/sP7ohqAEHkDU... More info about calibration targets: clui.org/newsletter/w...

this haptic display absolutely rocks. basketball is for everyone.

In the meantime, NHGIS (https://www.nhgis.org/) has much of the data you'll need, and will remain functional. NHGIS has the latest ACS data and Census data back to 1790 along with Census boundary files. You can support NHGIS here: makingagift.umn.edu/...

I was just throwing together a flood inundation example and tried something new. I did a hillshade on the inundation layer and had a crazy idea to set the exaggeration to -3. It produced a cool visualization. #GIS #Flooding #EmergencyManagement

A standout sentence: "resilience is best understood as the sum of numerous individual decisions and strategies. It is neither inherent nor immutable, and there is no universal strategy that reliably works across all types of crises" 1/2 #GreySky | #EMBsky phys.org/news/2025-01...

One more "How To" post is available on my blog for the break. It is on the basics of using NetCDFs and ArcGIS Pro to model Climate Change. It is a simplistic analysis but it shows the power of NetCDFs and what is possible. #GIS #ClimateChange #RemoteSensing #ArcGISPro justincolegis.com/20...

Don’t ignore Red warnings. If you are in the zone get in somewhere and encourage others to do the same. Stay away from roads, trains, rivers,flood water and coast lines if you can. Have torches and charged lights and charged phone and powerbank to hand

Running an experiment for our design fiction and participatory design generating platform today. Super excited. It’s been a while since I’ve done data collection that wasn’t just trace data. @justincolegis.bsky.social’s eventual first and second publications should come from this! #academicsky

Playing around with TerrSet liberaGIS (IDRISI) for the first time in about 10 years and it is still the same interface. Still not the fastest but some good tools. Curious to next test running it on my MacBook through parallels. #GIS #TerrSet

happy international shapefiIe day to all who celebrate

TerrSet liberaGIS (Formerly IDRISI) is now available for free. www.clarku.edu/cente... #GIS #RemoteSensing

So I have been exploring #GenerativeAI for use in map symbology creation. It has some interesting results and very odd quirks. This is one for special education providers. I used PS to remove the background (one of the quirks). #Cartography #VisualSemantics #GIS #GISChat

You know the "🔹AI Overview" you get on Google Search? I discovered today that it's repeating as fact something I made up 7 years ago as a joke. "Kyloren syndrome" is a fictional disease I invented as part of a sting operation to prove that you can publish any nonsense in predatory journals...

Thrilled to be able to share our new paper wrote with Alison Lloyd Williams @floodskinner.games On using 360 immersive storytelling to engage communities with flood risk Our project worked with youth, teachers & the Environment Agency #FloodEducation onlinelibrary.wiley.com/doi/10.1111/...

With #GISDay wrapping up, I just wanted to share the news that #IDRISI will be free starting December 2nd. IDRISI was the first #GIS software I learned and it has great tools for environmental modeling. www.clarku.edu/cente...

OMG! I'm so happy for deck.blue. I've missed tweetdeck and... you know. 😒X Looking forward to #GISChat finally being back in its own column feed.

I have not posted a map in a while but this is one that I have been working on for fun'. Tying to figure out doing a simplistic layout to convey a lot of information. #GISDay #GIS #Cartography
