Re: [PHP] Finding an Address
HI, It seems like you want something according to the following you know your start long/lat you can determine the long/lat arround it for every of those you determine the route. if you follow that route you know the house you find otherwise you can use an increasing circle and if it finds an address on the location, you may be able to determine which of the points in the circles (which increase in size) is closest. Does that match what you want? If not, could you further elaborate what you want exactly? Kind regards/met vriendelijke groet, Serge Fonville http://www.sergefonville.nl Convince Microsoft!

Re: [PHP] Finding an Address
well, not exactly. But I can help you (so can others) to go through code flow (it will probably be tedious) you have a position you start and a certain distance from that point (in a circle) From thereon you substract start(x,y) from dest(x,y) by substracting x from x and y from y the diffence is the amount of degrees between the two points are apart, if you add instead you determine a point. so for example you are currently at long: 75, lat: 31 and you want to know some point 6.9 miles away. you start by adding 0 to 75 and 0.1 to 31 you then have one point (both are degrees and one degree is roughly 69 miles) you can also do the opposite, add 0.1 to 75 and 0 to 31, you can also add 0.05 to both (again totaling 0.1), mind though the values that total 0.1 are absolute, even though the long/lat may be negative. The point is that the values added are combined the distance you want to measure against. From thereon you can determine if there is an address at the location (using reverse geo-coding). when increasing the number you add, you measure further and further you'll have to do that all arround the point you started from more information about how long/lat works: http://www.nationalatlas.gov/articles/mapping/a_latlong.html HTH Kind regards/met vriendelijke groet, Serge Fonville http://www.sergefonville.nl Convince Microsoft!

Re: [PHP] Finding an Address
You are right, there is more to it. The incentive from me was to not further complicate a problem that by itself can be very hard to solve. but still, a more accurate measure van only determined by including these concepts.
