As of this morning, Oregon is scorching the way for wildfires this season (so far). Utah is a very distant second: #wildfires #oregon

The following creates a spatially indexed #flatgeobuf (FGB) of #USGSLandSat ARD #metadata by polygon. It accesses over 2.3 million rows (currently). 1982 to present. It is blazing fast and does not require an API or complex client stack. www.postholer.com/portfolio/no... #GIS
America First. The U.S. is the largest producer of oil in the world. So why are gas prices so high in the U.S.? Because energy companies honor their highly profitable foreign contracts before the needs of Americans. So, um, yeah. America First. Thanks Don.
Stay up-to-date with the latest #surfaceSmoke conditions and air quality with this interactive map. Updates hourly: www.femafhz.com/map/39.74098... #wildfire #smoke #airquality
Tropical storm Elida and sea surface temps: www.femafhz.com/map/27.91676... Change the layer to sea surface anomaly to visualize how temps are compared to normal. Sea surface temps are actually below normal for a large swath near the California coast. #tropicalStorm #hurricane #elnino
Create a median composite raster from Sentinel-2 using only #GDAL This tutorial achieves the same result as #spatialthoughts Python tutorial: courses.spatialthoughts.com/python-remot... ...using only GDAL and Bash, without Python and it's dependencies. www.postholer.com/portfolio/no...
Pssst! Hey extremists. Yeah, you. Whether you're red-hat-wearing MAGA traitor or a hamas loving Woke revolutionary, a message for you. Your vitriol directed toward Lindsey Graham says everything about you and nothing about the deceased.
Creating multi-layer images with GDAL CLI pipeline, using various nested raster/vector pipelines. Data: ETOPO_2022 1KM resolution bathymetry/elevation, NaturalEarth and trail vector data. #gis
Our trail fires page is ready for the upcoming fire season. We've added video that shows smoke, hotspots, burn scars and fire weather index over the last 72 hours, in 1 hour increments. Choose your trail. www.postholer.com/trail-fires
More evidence against El Nino hype. Looking at the last 22 years, there's no evidence strong/moderate El Nino contributes to wetter weather. Only 2 of the top 10 years were moderate. 6 were Nina's!!! The opposite seems to be true in a changing climate.

El Nino: Hazard or hype? Social media is awash with "weather wandas" seeking clicks, professing doom & gloom about El Nino. Here's a look over the years of its impact in California, in terms of precipitation.
967 distinct eco-regions from the @EPA for CONUS, levels 1-4. That's 5,842 at level 4. Base map turned off for clarity. Zoom in to increase eco-region level. Click for name: www.postholer.com/map/Pacific-...
It seems folks are struggling with @fema Flood Hazard (NFHL) data. Create your own spatial database, allowing you to query by FIRMID, FIPS, community id, date, geometry and retrieve data in bulk: postholer.com/portfolio/no... @cloudnativegeo.org @radiant.earth @briannaritapagan.bsky.social
Anyone notice a massive increase of bad internet traffic coming from South America over the last few months? Here's looking at you #Brazil: www.femafhz.com/map/-17.9518... #gis #osint
Comparison of NBM QPF (precipitation) forecast model vs actual QPF amounts, for 2 events, Oct 24-27 and Nov 04-06 2025 along the California north coast. Consistency is an issue. @nws.noaa.gov #weather #california

Using PostGIS ST_LineInterpolatePoints to evenly get points from line features (roads) and ST_ClusterDBScan to get (mostly) non-overlapping points for road shields on interactive map. Using only st_clusterdbscan for non-overlaping GNIS place names. #30DayMapChallenge #points #postgis #leafletjs

State of California: 4th largest GDP in the *world*. 71% of the U.S. economy originates from blue states. Red states are being *subsidized* by blue states. What a complete embarrassment.
Per the #PCTA: "The Trump Administration this week formally announced its intention to roll back longstanding protections for Inventoried Roadless Areas in National Forests..." www.pcta.org/2025/scrappi... Map for all trails, layers->Protected Areas->Roadless Areas: www.postholer.com/trail-maps
California, the 4th largest economy in the world, has a balanced budget, *without a deficit*. Maybe the state isn't just a bunch of idiots after all? x.com/GovPressOffi...
