Question

Will this help draw weather fronts with Photoshop and Javascript?

I am a meteorologist. I use Photoshop to help annotate maps. One thing I always wanted to do, but couldn't, was draw weather fronts.

Recently I've come across some javascript used by leafletjs to draw fronts. Does any of what I've seen get me closer to being able to draw a front with a path? I know Photoshop understands javascript, but not much more.

This is very esoteric. There are few of you who can help. So thanks in advance.

Hey guys,

I have made AI brush set with common types of fronts (pattern brushes), download link below for anyone who could use it. Cheers,

A bit more refinement. Figured out the Highs and lows were not paths, but just letters, so changed that with the appropriate colors. Added a dashed line for the trofs also.

Modified the script to draw the paths and shapes, no dots now. I don't know about the high and low zones, those don't look right. Still need to add the symbols.

Yea, I made the script to put each front in a separate group.

Playing around with your data. I'm not really sure how it's used, but looking at the data, it is a series of arrays for each type of front. I played with the cold front data. It seems to be a series of nine arrays with a series of coordinates in each of the 9 arrays. So I wrote a script that creates a group for each of the nine arrays and then plots a dot for each of the coordinates. I have not idea if this is correct, and to spread the dots out, I multiplied each x & y value by 10 and added 1500 to the y values, as they were negative values. So if you start with a 1000px X 1000px document with the unit values set to pixels, you can see how this works.

It's going to take me a little while to absorb this. Meanwhile here's how those points work...

COLD.push([[[49.7, -64.5], [48.4, -65.4], [46.2, -68.1], [44.3, -72.2], [42.1, -77.8]],

This cold front starts at 49.7N Latitude and -64.5W Longitude. OK -- it really should be W or - not both, but you get the idea. So, this first point is around the Gulf of St. Lawrence in Canada, then into Maine and so forth. Fronts are a little fluid. These lines are never exact. Each front runs to the first double closing brackets.

They use a fixed url to store this data, so http://www.wpc.ncep.noaa.gov/exper/nationalforecastchart/data/fronts92f.js will always contain data corresponding to what's on the map.

Chuck, thanks again.

Ok, so I did have the right idea that the set of coordinates were for o e front - each array with a set of coordinate arrays. Just need to figure out the plotting in relation to a Photoshop image and unit value.

For a stationary front, you could draw both the warm and cold fronts then mask them:

Chuck - you are currently my favorite person on Earth. I can't begin to thank you enough. I've been looking to do this since I first started using Photoshop, over a decade ago.

I also had a chance last night to look at your pattern drawing app for Photoshop. Thanks for making this contribution to the community.

I hope you don't mind, but I'll be back with questions later (surely).

Again, thank you.

That is a very elaborate dynamic web page the has a world map you can drag around zoom in and out and control weather overlays. The overlays only seem to be available north America. If you are asking if Photoshop can create a web page like that the answer is no. Photoshop may be used to create some of the overlays the web page uses Shape with fills, Text, Paths Stroked. A Photoshop script may be able to be written to read a file that has prepared weather information fot plotting weather front, storms areas etc and create the overlays for the web page to use and save them for the web server to access. Some of the plots may be a special weather symbol font would be like text on a path.

First, thank you for your assistance. Yes, the only thing I want to be able to do is draw fronts. If you check Google over the years I've asked this question many times. Sadly, the answer is no, or use Inkscape/Illustrator.

However, the fronts you see on the Weather Service site are produced using javascript (those are the descriptions in my file, the actual points are elsewhere in the code) and Photoshop speaks some javascript.

That last sentence is the extent of my knowledge. But if it's possible to do, I'll do my best to figure it out. This is a big deal for me.

Again, thanks.

The good news is cold fronts are out of the north or west around 99% of the time. I saw the cold front you drew. There could be one that looks like that, but I've never seen it. They all bow positively.
Warm fronts are mainly from the south and west.
Of course south of the equator it's all reversed and near the equator there are no fronts at all.

Okay, this script will only work with this map, as the points are adjusted for it.
Here's what I got plotting just the cold front.:
