Zoomed out you get clusters of turbines, zoom in for individual turbines. Mouse over or click turbine for more info.

We've added wind turbines to our data on Postholer Interactive Maps. It's surprising how many there are, not just along the trail.

With that said, the on trail turbines near Tehachapi Pass on the #PacificCrestTrail have really exploded in growth over that last few years.

Get trail climate in chart format along any section of your favorite trail. Pick your favorite trail:

Tale of the Trail: Land Cover Change

https://postholer.com/articles/Tale-of-the-Trail-Land-Cover-Change

Introducing 28 years of land cover change on your favorite trail! This is the latest feature added to Postholer Interactive Maps. It's made possible by @USGS and Multi-Resolution Land Cover Characterization Consortium, which produces the National Land Cover Dataset or just NLCD.

Given the @PCTAssociation's departure from the facebook social media scene, we've created a new facebook group specific to the #PacificCrestTrail (#PCT)

With all the resources http://postholer.com has provided since 2006, it seemed like a good fit for us to fill the void.

Hurricane #milton storm surge impact on structures with a floor area greater than 700 square feet:

192,000 buildings will see 3-6 feet of water.
204,000 will see 6-9 feet of water.
56,000 will see more than 9 feet of water.

Bridges over waterways will also be submerged!

This uses current storm surge forecast data from @NHC_Atlantic
and building footprints from @cloudnativegeo.

Recently, @NASAEarthData
published a new Global Urban Polygons and Points Dataset available at NASA' #SEDAC
.
We've taken this data and created an interactive map showing points and polygons of population data found in the dataset:

https://www.femafhz.com/urbanPopulation

Points are shown if the population is greater than 200K between zoom levels 1 and 6. Greater than zoom level 6 all polygons are shown. Click on a point or polygon to get a graph of the population from 1975 to 2030.
