/** The point-in-polygon algorythm allows you to programmatically check if a particular point is inside a polygon or outside of it. A common way to tackle the problem is to count how many times a line drawn from the point (in any direction) intersects with the polygon boundary. If they intersect an even number of times, then the point is outside.
 I used that approach in this PHP code, which doesn't contain detailed comments yet. A few people asked if I could post it anyway, so there it is... I'll try to add some more comment as soon as I have some spare time.

 The returned values are:
 "vertex" if the point sits exactly on a vertex AND you left true as the value for $pointOnVertex.
 "boundary" if the point sits on the boundary. If $pointOnVertex is false, then "boundary" is also returned if the point is on a vertex.
 "inside" if the point is inside the polygon.
 "outside" if, you guessed it, the point is outside of the polygon.

		/*Elevation - SRTM3
Shuttle Radar Topography Mission (SRTM) elevation data. SRTM consisted of a specially modified radar system that flew onboard the Space Shuttle Endeavour during an 11-day mission in February of 2000. The dataset covers land areas between 60 degrees north and 56 degrees south.
This web service is using SRTM3 data with data points located every 3-arc-second (approximately 90 meters) on a latitude/longitude grid. Documentation : Nasa

Webservice Type : REST
Url : api.geonames.org/srtm3?
Parameters : lat,lng;
sample area: ca 90m x 90m Result : a single number giving the elevation in meters according to srtm3, ocean areas have been masked as "no data" and have been assigned a value of -32768
Example http://api.geonames.org/srtm3?lat=50.01&lng=10.2&username=demo

This service is also available in XML and JSON format :api.geonames.org/srtm3XML?lat=50.01&lng=10.2&username=demo api.geonames.org/srtm3JSON?lat=50.01&lng=10.2&username=demo

The text version of the service also accepts a list of lat/lng for the parameters 'lats' and 'lngs'. On the free server the number of points per call is limited to 20, for the premium service the limit is 2000:

    [0] => the daily limit of 30000 credits 78.31.45.206 has been exceeded. Please throttle your requests or use the commercial service
    [1] => daily
    [2] => 30000
    [3] =>  78.31.45.206
