To the Bootcamp, University, Community College or person who just completed a kickass side project that could land them a job. Here are my 12 points of advice for starting out on your Geospatial Journey.


1. Own your space in the meeting, you belong there. But also remember so does everyone else.

2. Let people show you who they are. People say things about themselves, but their actions speak volumes.
3. Find a passion in Geospatial, it will refill your emotional love of the field when your day job doesn’t

4. Find a Mentor, then later be a Mentor

Here is a selection of the *coolest* 3D maps and map-like worlds I've seen on Twitter in the past months. Wonderful dynamic, interactive, static, creative or artistic visuals. #Dataviz #3dMap #GIS #3D #Cartography #GISchat 1/23🧵⬇️
Thomas Kole | @ThomasKoleTA 's stunning realistic 3D model of Tenochtitlan capital of the Aztec Empire (now Mexico City) made in #blender using #geometrynodes. Stunning water, clouds & details. #b3d #CDMX 2/23 🧵
Craig Taylor | @CraigTaylorViz 's mesmerizing ship data animation of the Gulf of Mexico. Made in #Cinema4D, with pleasant colours and satisfyingly well-made animation and light reflections. As always impressive work. 3/23 #3dmaps

по просьбам трудящихся, тредик про SQL (postgres/postgis), разберём ваши вопросы и что-нибудь поломаем, погнали:
начинать нужно с азов. самый короткий запрос - ";". ломает людям мониторинги, потому что нагрузку создаёт, а текста не имеет. Image
в запросе обычно нужны какие-нибудь ключевые слова, которые бы что-нибудь вернули. из базы данных получать таблицы помогает запрос select. Image

I might be the last one on the population flag map bandwagon, but I’m pleased with the result! Thanks to @StatCan_eng @StatCan_fra for providing nearly *half a million* polygons to select from.

#cartography #gischat #QGIS #canada @CanadianGIS @GANSorg

(Details in the thread.)
Over the last couple of weeks people have been posting their population flag maps, so I thought I’d try my hand at creating one for Canada. I figured that with detailed census data, I might even be able to include a reasonable facsimile of the maple leaf.
So I went to download the boundary file of Canada’s 56,589 dissemination areas, the smallest geographic area for which full census data is provided. That’s when I discovered that Statistics Canada also provides a 'dissemination block' boundary file.

Examining the status of improved air quality due to COVID-19 lockdown and an associated reduction in anthropogenic emissions
#gischat #sentinel5p @CopernicusEU
@CopernicusData @CopernicusECMWF @ESA_EO
Clean air is a fundamental necessity for human health and well-being.
Human mobility data from Apple (for city-scale) and Google (for country scale) was used for examining the connection between human interferences on air quality ESs.

1/x This morning I woke up to see viral maps incorrectly comparing the damage area of the Beirut explosion to London and New York. I have corrected the maps with a little thread to explain my corrections. img 1. tweet with my notes. img 2-4. my new maps.
2/x The original map looks like it was made by the @DailyMailUK It's a pretty clear map... except for the fact there is no scale or distance indicated on it. (Thank you #gischat sleuths that helped me find the original).…
3/x A curious and well intentioned person used an online tool that slaps circles onto google maps, but none of the maps show any distances or scale. And the google maps are, of course, projected in Web Mercator, which does NOT show distance equally across different latitudes.

Surveillance from Orbit and privacy thread.

🕰 Let's do some time surfing and clock back to 1950. Image
Since ever I think (feel free to correct me), is a strategic move to have an overview of your map in-game.

That's where the fog of war was coined.

You just want to be situationally aware of your participants in your Ops. Image
You just want to capture the uncertainty regarding one's own capability, adversary capability and adversary intent during an engagement.

Military forces are trying to reduce the fog of war through m. intelligence and leverage friendly force tracking systems.

Glacial floods caused by the tremors could cause an eruption.

A glacial lake outburst flood (GLOF) is a type of outburst flood that occurs when the dam containing a glacial lake fails.…
An event similar to a GLOF, where a body of water contained by a glacier melts or overflows the glacier, is called a Jökulhlaup.

A jökulhlaup (Icelandic pronunciation: ​[ˈjœːkʏlˌl̥œip]) (literally "glacial run") is a type of glacial outburst flood.…
Can be upcoming glacial floods detected from orbit?

#Data2Information: A Tale of #OpsDashboard Development

A tweet series about being presented with a need and a dataset and then turning that data into information in the form of a dynamic dashboard using @ArcGISOnline (with my added thoughts).
I have been configuring quite a few #OpsDashboards - @ArcGISApps lately so I thought I would chronicle my most recent experience as I assume others find themselves facing the same challenges/opportunities (or I atleast hope I'm not the only one).
I received a forwarded email saying "Any ideas on something cool?" FYI - this is the type of email I love to get because it's basically an ask with free reign of creativity (while being budget conscience of course).
