SunCalc

i would like to make an app which exactly shows me ,earth and sun with proper elevation direction and length of shadow. I mean me on earth with respect to sun.

The National Oceanic and Atmospheric Administration (United States) has a web site (http://www.esrl.noaa.gov/gmd/grad/solcalc/) that pinpoints the major daily solar event times for a particular location using pinpoint maps. The solar event times...

I have just found how to use sun compass on www.trainspots.co.uk. Fantastic! I have spent years laboriously trying to work out when the sun would be in the right place at the right time for photographing trains throughout the UK. Goodbye...

currently when you use the rotate button the sun info does not update for the new orientation of the map. It should!

Add the ability to set a start and end date, and update interval, and see how the sun coverage changes.

Apparently the times in the URL are in the browser's local time. So e.g., http://www.suncalc.net/#/69.6492,18.9553,7/2013.09.22/11:02 only shows the exact solstice for people whose browsers are configured to GMT+0.

Hello Vladimir. Great App and I use it a lot. The map view could be improved with say a satellite view. Sometimes the map view - unless you overlay onto, e.g. Ordnance Survey (in the UK) is not too accurate. Overlaying your app onto Google...

Great tool for photographers. Thank you!

When zoom into large scale, it would be convenient if the circle can change size through dragging.

I want to be able to see the shadows shift with the sun as I move the orange dot for the time, while I'm at street level view.

WHen zooming into google maps in some areas, satellite photography is replaced with aircraft photography. google allows the user to change the direction of North in the map. The suncalc application doesn't track this change, displaying incorrect...

Know sun altitude in such time can be useful

this does not appear to be true solar North South Axis. Please graphically and numerically represent relation of true solar North South to Magnetic North South.

There should be quantification of the arc values at the top and bottom of the yellow annual region. Also, you say "The closer a point is to the center, the higher is the sun above the horizon," but your graphic doesn't reflect that quantifiably....

when zooming out on the map I find that the lines do not extend far enough across the map, I've been trying to get a picture of some local landmarks at dawn but its difficult to get an exact time

HACER EL MISMO SISTEMA PARA LA LUNA

Sun will cross the latitudes between 23.5 North and 23.5 South twice in a year. Intuitively this motion of Sun between the Tropics would be a Simple harmonic motion with amplitude of 47 degrees of latitude and a period of 1 year. Is it possible...

It looks as though I can make the sun trajectory go through the object and it's shadow point thus allowing the sun line to show the trajectory of the shadow across the image. Is that the case and if so does the trajectory line need to be scaled...

Very cool web app! I would like to echo posts of others to calculate the length of a shadow. It would be great to place an object (wall or even just a vertical line) of a variable height in the scene to calculate the shadow at different times of...

I would like to see the point of location's geographic coordinate system, the latitude and longitude, written in degrees minutes and seconds.

compare the sunset and sundown on two locations

I would like to be able see a compass overlayed the images to see the radials of the compass.

When I'm sliding the sun over the time bar, or looking at the web site at at time when the sun has not yet risen it would be interesting to see where the sun was located on the map (even tho it is night, dusk or dawn.)

I use this program for my solar tracker. Elevation would make it perfect. Merry Xmas / Happy new year

THER'S NO ROCKET SCEINCE IN THE QUIESTION, IM A BRAIN DEAD OSSIE,AND WHAT WE DO IS PUT AN TRANSPREINT,OR LIGHTGO FILM,OF THE FACE OF THE COMPASS DRAWING,PLUS THE SUN RISE,AND SUNSET Deg POINTS,ALL IN THE ONE OVER LAY,THAT CAN LAY OVER A MAP, OR...

I would like there to be more information on the print out: Name of location (if exists), date calculation is for and the sunrise, sunset data shown in upper right should all print out with graphic.

It would be nice if the program had an option (button) to automatically showed both longest and shortest day sun arcs for orientation of buildings on sites.
