A simple GPS tool for the phone

September 5, 2022 by Leave a Comment

If you visit this site often, you likely have a favorite map app on your phone. I certainly do and I have installed dozens of apps over the years. Most focus on placing your location as a dot on the map.

The dot

Any map app that shows your location as a dot on the map fosters a dependence on your exact location. We end up saying, "I am here" instead of asking "Where am I?"

To build strong spatial awareness, we should look at the dot after studying the plain map and doing an exercise in terrain association. Can we orient the map (best done with a paper map, folks) so that map north aligns with observed north? Can we then identify features on the map and estimate their distance from us?

These are questions in topograhic map reading. If you carefully observe your environment and compare its representation on the map, you will not need the dot.

When there was no dot

Let’s say the early 1990s. Before that time, we used paper maps. Soon after, handheld GPS units became popular and only showed coordinates for your position and maybe some other location statistics like speed, elevation, distance & bearing to next waypoint. They were often used with a paper map that had a grid (with linear units on a flat space) or a graticule (angular units on a curved space) that helped a user measure their location.

Using coordinates, we looked at the paper map’s margin for marks that pointed you to a general location. To find the exact location, we looked up and asked, "Where am I?" and compared the map with what we saw. We built a mental map of our surroundings. There was no dot.

An app without a dot?

So, we thought we would kick it back to the 90s and make a browser app that mimics these early devices. Because our maps have detailed graticules and mile markers for the Sheltowee Trace, this app should compliment your journey into topography and map reading. This app is designed for mobile devices and below is a screen capture of a use on an iPhone.

Toward a scenic trail index

August 12, 2019 by Leave a Comment
Sheltowee Trace, Daniel Boone National Forest, and Big South Fork scenic trail index
Visit the web page

Over the years we’ve pursued some measure that reveals the character of 900+ miles of trail here. Often we talk about a trail’s length or steepness with other dimensions gleaned from the base map. In this experiment, we are creating zones at discreet locations along trails and estimating the character of that location.

Over 14,000 polygons are shown on this 3D Mapbox map. The color indicates the type of scenery and height shows how much relief is the area. Future additions to this map include adding a searching tool and summary statistics for each trail.

New images and data from GOES-16

Visit the page to view and download imagery

Over Christmas break, it was time to automate collecting and displaying the incredibly detailed imagery from the GOES-16 Advanced Baseline Imager. A problem that plagued previous efforts was not accessing the raw data, a netCDF formatted file for the contiguous U.S. which can be downloaded freely from a variety of cloud data hosts. With the raw data, one can project, modify and use it in web mapping libraries like Leaflet.

This page offers a slippy map of grayscale and color imagery and is updated every 15 minutes. You can download GeoTIFFs of rendered layers that can be used in GIS applications.

Sheltowee Trace interactive mobile map

June 9, 2017 by 3 Comments

Locate yourself on the ST

We’ve updated our map of the Sheltowee Trace on our ST site: sheltoweetrace.com/hike. The map has symbols for official recreation sites and trails for the Daniel Boone National Forest, Big South Fork National River and Recreation Area, and Cumberland Falls and Natural Bridge State Resort Parks. Of course, it has the ST and mile markers from the northern terminus.

Since we deployed this map last year, we have updated the Leaflet and MapBox JS to make the work with a GPS-enabled device as long as you have a cellular data connection. The points of interests and trails are clickable with useful travel information.

Our next goal is to fill out the map with more scenic destinations and include more photographs. Let us know if you have any suggestions.

Big South Fork in Early Fall

October 12, 2011 by Leave a Comment

The first weekend of the October saw us in the Big South Fork country enjoying a dramatic change in weather. The first day was warm and sunny, but as evening set, the winds increased and rustled the treetops throughout the night. The morning was overcast, mild, and as we began our descent into the Big South Fork at Blue Heron, the sky thickened into sweeping rolls of stratocumulus clouds.

El Niño to make the mountains colder and drier this winter

October 18, 2009 by Leave a Comment

Predicting climate in the old days relied upon observing cues in nature. The Farmers’ Almanac finds that people looked at woolly worms in late summer in get a sense of winter. The more black hairs on the worm, the colder and wetter the winter. Of course woolly worms come in all configurations of black and orange colorings so how could a worm’s coat predict winter? It can as an analogy;  you look at the forecast to decide which coat you’re going to wear before leaving home. I think you would want to wear a black coat as opposed to a white coat on a very cold and sunny day to maximize the amount of solar energy you could absorb. Woolly worms just plan far ahead.

Today we track global changes in wind patterns and sea surface temperatures to predict weather conditions. NOAA’s Climate Prediction Center has issued a climate forecast for this winter based on the El Niño pattern emerging in the Pacific Ocean.

Below are winter predictions for the U.S. indicating greater or lesser chances for departures in average winter temperatures and precipitation.

precip

El Niño is a departure from average sea surface temperatures created by a change in the intensity and direction of equatorial winds. In a normal period, strong easterly trade winds blow across the Pacific and upwell cold, nutrient rich waters on the west coast of South America. These same winds also pile up water in the western Pacific so that the sea surface is about 2 feet higher at Indonesia than at Ecuador.

Normal Sea Surface Temperatures in °C

In an El Niño cycle, the winds are not as intense and warmer sea surface temperatures extend further to east. This change has a global impact on weather with increased precipitation on the west coast of South America and the south & east coasts of North America. Warmer than normal conditions also occur at higher latitudes in North America and over the Pacific ocean.

Rainy May: on track to be the wettest May ever

May 8, 2009 by

Spring is typically a wet month. However over the past week, Eastern Kentucky has experienced unusual rainfall amounts. The record for the month is 10.78 inches in 2004; and no other year has been above 10 inches for May. The only year that saw over 9 inches of rainfall for May was in 1995. May during 1983 and 1984 were the only times over 7 inches of rainfall.

From the National Weather Service in Jackson, Kentucky:

"2 TO 5 INCHES OF RAIN HAS FALLEN ACROSS EASTERN KENTUCKY DURING THE
MONTH OF MAY. THIS IS OF INTEREST...SINCE WE ARE ONLY ABOUT ONE
QUARTER OF THE WAY THROUGH THE MONTH. HEAVY RAINFALL IS VERY
POSSIBLE AS WE HEAD INTO MOTHERS DAY WEEKEND AND COULD PUSH RAINFALL
AMOUNTS UP ANOTHER INCH OR TWO.

THE AVERAGE PRECIPITATION FOR THE MONTH OF MAY AT THE JACKSON
WEATHER OFFICE IS 4.92 INCHES. WE HAVE ALL READY RECORDED 4.12
INCHES OF RAINFALL AS OF THIS MORNING AT 7AM. IT IS TOO EARLY TO TELL
...BUT WE ARE CERTAINLY ON TRACK TO HAVE ONE OF THE RAINIEST MAYS
EVER. THE RAINIEST MAY OCCURRED IN 2004 WHEN THE JACKSON WEATHER
OFFICE RECORDED 10.78 INCHES FOR THE MONTH. THIS WAS THE ONLY MONTH
OF MAY THAT OVER TEN INCHES OF RAIN FELL. MAY OF 1995 HAD 9.91
INCHES AND WAS THE ONLY MONTH WITH OVER 9 INCHES RECORDED. THE NEXT
HIGHEST TOTALS WERE OVER 7 INCHES AND THAT OCCURRED IN ONLY TWO
YEARS...1983 AND 1984.

(raw) 3D map of Eastern Kentucky

April 16, 2009 by

As we gear up for the Sheltowee Trace topographic map, I thought it would be interesting to see if a complete 3d map of the ST could be printed. Unfortunately, it would have to be a huge sheet of paper to get the detail necessary for a good map. But as an online viewer, I see potential. This sample is a raw render output and you can see well the basic physiography. Now we just need to add trails, transportation, labels, etc….nothing too much, just about 6,000 sq. mi. for the Daniel Boone NF.

Why we use aerial photography

April 2, 2009 by

Many customers ask us why we use aerial photography. Often it’s hard for some readers to understand because of terrain inversion. Let’s take a Q&A with a real customer:

Customer, “Hi guys. I just wonder if anyone has ever discussed with you the fact that the shading on your maps appears to be reversed. That is, the high points appear like low points and vice versa, if one is looking at the map oriented to north. If one turns the map around, so it is oriented to south, then everything looks correct. So, my guess is simply that the shading is on the wrong side of the ridges. ”

Our response, “Thanks for asking a question that has popped up a few times. In the mapping biz, it’s called terrain inversion and it is a problem sustained by tradition. Before aerial photography, most terrains were shaded as if the sun was in the upper-left corner. This was established as cartographic tradition because we read from upper-left to lower-right.

This worked fine until aerial photography became used as base maps. In the northern hemisphere, and especially at our latitude, the sun is never shines from the north. All of our shadows fall from south to north, completely opposite to how they’re depicted on most conventional maps. Cartographers in the southern hemisphere think we’re crazy up here moving the sun around to accommodate tradition at expense of reality. But they have the advantage of sun always being in the upper quadrants, thus giving the type of illumination you’re probably used to.

But we use aerial photography in most of our maps, because it is reality and at the right scale is far superior to an artificial hillshade in our opinion for couple reasons. You can see areas that are really in shadow, which indicate different plant communities. You can see canopy type, density, and other indicators for type of forest. If you’re a photographer, these images show depth and lines of shadow, helping you predict the kind of light you want for a photo. Finally, if you have take an aerial photo up high to orient, you can do so by shadows.

Detail from our Big South Fork map with aerial photography. Note the north facing cliffs are in shadow, just as in found in the wild.

So in my defense, I say it’s all about sunlight. I understand your problems and trust me, it has stirred the anger of my peers at cartography conferences. We’ve been flamed on blogs for this apparent flaw, but in our humble opinion, an aerial photo is not the problem, it’s tradition.

It’s sounds like you have a lot of experience with maps, and I respect your opinion. However, I think if you get used to aerial photography, you’ll find distinct advantages. Also in defense of tradition, I did illuminate our recent map, Trail Atlas of the Great Smokies from the NW. That map does not use aerial photography so it was an easy decision.”

Big South Fork Trails

February 24, 2009 by

The trails in the Big South Fork are were not impacted by the ice storm that hit the northern portions of the Daniel Boone National Forest. Hikers have reported excellent trail conditions, though fording Rock Creek or the Big South might be a little cold and water levels high this time of year.

Big South Fork Trail Guide, 2nd Edition

November 14, 2007 by

New 1:127k Trail MapWe’ve added a new map and packaging to our Big South Fork trail guide. Our new map is a 1:126,720 scale trail map of the entire Big South Fork area including the trails around Stearns in the Daniel Boone National Forest and the new horse and multi-purpose trails along Darrow Ridge.

The map is sized at 13.5 x 18.5 inches and is 2-spot colors, black and a metallic ink that looks similar to anodized aluminum. The metallic ink has the useful property of shining under a headlamp and makes reading the trails easier in low light conditions. The map has a 2-minute GPS graticule for navigation and geocaching. The map shows all recreation areas for park and adjoining public lands from Straight Creek in the Daniel Boone NF to Peters Ford in the Big South Fork. On the reverse, we have our classic 3D map of the park.

Old Trail SignFor the new packaging, we’ve added a 2-color cardstock overwrap that makes a more impressive retail display. The wrap describes the historic trail signs that you might find in the Big South Fork. Gone are the rustic old wooden stencil-painted signs. Over the next year, the park will replace the original trail signage with new blazes and trailhead markers. The blazes are recycled plastic tags that indestructible and hardly distracting since they’re hard to see. While I prefer the old wooden signs, I understand the new signage will be easier to maintain and is more informative at trailheads.
