What is a LBS?
They are a LBS and you are a LBS
Everyone’s a LBS, S, S, S….

HTML5

IP Geolocation
You have an IP Address & we know geographically where that is.

IP GEO Properties
Always On
Static in Nature
No Permission
25-50 Mile Localization

IP GEO LIBRARIESHow it gets done

HTML5 Geolocation
Permission based access to users’ location.

HTML5 Background
A collection of HTML standards being brought into adoption.
Not something that’s going to show up all at once, not even on your birthday. #sorry
Many features are already in adoption with current browsers.

HMTL5 Geolocation
A singular feature of the HTML5 Standard
Off By Default
Can be coded as dynamic
Permission Based, Error handling can be difficult

HTML5 Geolocation APIHow it Gets Done
Cell Tower Triangulation
Device GPS
IP Geo Libraries

HTML5 Geolocation API
IE – 9.0+
Firefox – 3.5+
Safari – 5.0+
Chrome – 5.0+
Opera – 10.6
iPhone – 3.0+
Android – 2.0+

Browser Adoption

IE Support #Fail

Firefox Support

A Safe AssumptionBefore the Opt-In
1+ out of 2 Users
Can Currently Support HTML5 Geolocation

Google Analytics Will Set You Free

Plugins

Obligatory CODE SLIDE
function get_location() { navigator.geolocation.getCurrentPosition(show_map); }
// Callback function once location has been granted
function show_map(position) { var latitude = position.coords.latitude; var longitude = position.coords.longitude; // let's show a map or do something interesting! }

Stand and Deliver
You, or your client, as an LBS

Best Practices
Location, Location, Location with Balance, Balance, Balance
Give the User A Logical Exit
Don’t Be Evil, Get Consent, Allow Record Removal
Privacy Policy FTW

Never, Never Never Ever
Hello [geocity]! Welcome to my site!
#FAIL #FAIL #FAIL #FAIL

Super Simple LBSing.
Step 1: Put Your Content to City Categories
Step 2: Load The User’s Location Into Shortcodes
Step 3: Get Loopy

The Basic Geo Loop
<?php$city = do_shortcode('[geocity]');$args = array('category_name' => $city);$myCityQuery = new WP_Query($args);if ($myCityQuery->have_posts()): while ($myCityQuery->have_posts()): $myCityQuery->the_post();//post stuffendwhile; endif;
?>

function getGeoDistance($lat1, $lng1, $lat2, $lng2, $miles = true)
{

$lat1 *= $pi80;
$lng1 *= $pi80;
$lat2 *= $pi80;
$lng2 *= $pi80;
$r = 6372.797; // mean radius of Earth in km
$dlat = $lat2 - $lat1;
$dlng = $lng2 - $lng1;
$a = sin($dlat / 2) * sin($dlat / 2) + cos($lat1) * cos($lat2) * sin($dlng / 2) * sin($dlng / 2);
$c = 2 * atan2(sqrt($a), sqrt(1 - $a));
$km = $r * $c;
return ($miles ? ($km * 0.621371192) : $km);
