SATSIG Forum archive of comments about the latitude and longitude finder

I have just put together a page to help people find their latitude and longitude.
 
See: http://www.satsig.net/maps/lat-long-finder.htm 
 
Please try it out and tell me your review by adding your Reply below.  Many thanks.
 
Best regards, Eric.

I think your new map is pretty good. Takes a little getting used to, but what doesn't? Course I don't know a whole lot, not having a satellite TV or being able to start a new thread (I can't find the satellite internet forum board index page ) so I must ask while I'm on the system now. Azimuth and elevation angles I understand, but I've been (feels like all over) on net and can't find a definition of skew and polarization angles. Think I saw something which said that skew was equal to the longitude of satellite, but not sure I believe it. Also, which satellites are for DirectTV and which are for DishTV. Sorry to sneak in questions like this. Maybe you can tell me how to post since I can't seem to figure it out.   Thanks for your time.

Thank you for your comments.  
 
Regarding the world map and finding your latitude and longitude on my page, there are good underlying city, town and road street maps for the US, UK, Ireland and Japan.  For other countries I am working on adding a large number of major towns so the identity of places in the satellite view images is easier to work out.  If anyone wants their nearest major city marked, please tell me.

For explanation of skew, or the feed polarisation rotation angle, go to page http://www.satsig.net/polangle.htm
 
Happy Christmas and best regards, Eric.

Eric,     Great idea, I like the gui approach to finding the info. I think many users will like the visual method, instead of digging though drop down boxes used in some other tools.

Thanks Tom
 
I've just uploaded a new version  with some cities marked.  My finger is a bit sore clicking all the time to get the locations in the right place.  In some cases I have picked the local airport.  Comments and new suggestions for places to add welcome.
 
Next task is to maybe add some names if I can work out how to do it ??
 
Best regards, Eric.

Thanks very much for your time and attention. Wandering around your website answered some things before I stumbled onto your reply. Next time I'll try a new thread. MAY YOUR CHRISTMAS BE MERRY AND BRIGHT!   jingelrat

Eric,
 
Just a few uneducated guess on how to add more names. Can they be imported from a know source or
 a table of lat. xx.xx /long. xx.xx=city name?

Thanks.
 
I've just fixed a bug that was generating as many as 200 lines in the log file every time someone accessed the lat long finder page.  I've stopped the multiple downloads.   The tiny square dot icon is now downloaded once  only and then reused locally many times on the visitor's browser.    
 
Does anyone know of a copyright free list of the latitude longitude coordinates of say the top 500 cities ?.  I have put in 196 cities so far, based on my own measurements. You can read the coordinates if you do "View Source" when looking at the page.
 
Now added a two pixel black/white dot in the centre of the map !   
 
Best regards, Eric.

Eric,
 
Check with these people, they have lat/long listings on their website- not sure on what you could use or not.

I checked out the page. It's nice.
I looked up my location Riyadh Saudi Arabia and I came up with ( Latitude = 24.686952411999154, Longitude = 46.58203125)
Is this accurate? Does this value differ from one part of the city to another?
Thanks

I am pleased to hear you managed to make it work.
 
I think you have selected a road junction to the north west of the city.    There is an arrangement of two parallel roads running east-west, with some building developments visible towards the eastern ends.
 
The lat long values alter even for small movements of a few meters.  Fortunately, for dish pointing, accuracy to one decimal place all that is required.
 
My little square markers are just to help you find Riyadh in the first place.  Once you are near, the satellite image will help you home in your locality.    
 
I have yet to work out how to make names appear when you click on the markers.
 
Best regards, Eric.

Thanks for this site . Its brilliant

where did you get this from?    it says there is no map for this region

Click on "Satellite" at the top of the map and it changes the display so you can see the ground.  Zoom in and try to work out from the main roads, where is your location.  The resolution varies from place to place but roads are normally quite clear.
 
There is a problem for people located out in the country away from features which they can recognise.    They may find it difficult to even find their town or village in the first place without more guide markers for the more significant towns.
 
I have just added Al Madinah, and marked a cross roads where you can see the traffic waiting.  
 
Best regards, Eric.

Eric.   This site is even better than I thought. Roads are clear you can actually use main roads and highways to get  latitude and longitude of any location within Riyadh  
Thanks for this great site

It is a great tool thank you very much.  It help me so much in adjustment my dish in Iraq-Basrah. Thank again
