Hi experts, I try to directly check in a map of a certain point is in a polygon. see: http://profec.nl/profec/gmaps/index1.php
first lookup my code. The problem is that, as you can see in the first popup, javascript thinks polys.length() is 0, but in reality polys.length() is 2, as you can see in the second popup. What i think is that the code goes faster then xml can load. Strange enough the script works in IE. Maybe the problem is solved when i pre-load the polygons before i do a poly.length() function? Please look in my code to better understand my problem. My intention is an applicatie with: 1. longitude+latitude as input from a GPS device 2. the input is checked against several polygons on a map 3. the output is a unique id that belongs to the found polygon. 4. I use the id in my further program because the id is identical to an id in a database so i only use the whole map as a check function to know in which polygon my GPS exists. Maybe another solution is not using the google map at all, and just lookup if my current gps coordinate is in a specific list of polygons, using point-in-polygon algoritme http://alienryderflex.com/polygon/ But i thought because the google map can tell me directly in which polygon the point is i dont have to walk through the whole list of existing polygons, and thereby the google map solution is faster. But at the moment i realy doubt this! Allready big thanks to the people try to think with me.
