GPS Coordinates

Hi All,

I have 300 buildings all over Toronto... we are in the process of setting quadrants and dividing the buildings accordingly.

The quadrants are set from one highway to three others (setting the North, east, south, west diameters).

I've gathered the coordinates for all buildings but need to figure out which one fits into which quadrant...

I don't know how to go about this...

Any suggestions?

Format ex:

1 BENVENUTO UNIT (Lat)43.6818436 (Long)-79.4003071
2 FERNDALE AVENUE (Lat)43.1556978 (Long)-79.2123856

DP978,

Thanks, i'm going to give it a try...
But as i have 7 quadrants, would your method prove to be too time consuming?
Or is that the only way?

Zbor,

Funny enough, that image did help!
Genious...

Thanks,

So if 43.8 if the center line between North and south subtract 48.3 from all Lat values, negative values end up in the south, positives in the north. Do a similar thing for East and West.

Lets assume you pick -79.4 as your Long value, I am going to assume anything more negative is West, less negative is east.

you would do the following -

For location (43.743, -79.427)

( 43.743 - 43.8 ) = - (South)
( (-79.427) - (- 79.4) = - (West)

Thanks for taking the time to explain in great detail... I see what you're saying (took a while! You know what they say about women and maps..... haha) I'm going try your method with my data... i'm sure it'll work just fine... if not, i'll be back! =)

Thanks again,

Zanna

You have to be careful with 7 quadrants since cutting somethign with 2 axis will give you overlap in other quadrants.

You may need higher powered math using Radians to slice your quadrants into pie pieces, or if you need rectangles you are going to have to use many conditional statements.

I decided to stick to 4 quadrants for now.. as the other 3 are small and can be done manually (while i create the conditional statements, etc for future use).

Good choice ;-)

Let us know if you have trouble.

Thanks for the example Richard!
Definitely helps...I'm going to continue plugging in all my data.

Thanks for spending the time! Really appreciate it!
