Hello,

Scanning all the points in a map ( X and Y ) and using ObjectsFromPoint(X, Y) , some streets are not detected.

I zoom enough to see the streets , but some are lost while looping.

Is there a method to have more details about the street name in a map?

Thanks
Delphine

My code looks like this :

Code:

x, y are points in the screen 
fr, obj , objmap are objects 


For x = min_X to max_X
    
    For y = min_Y to max_Y 

     	fr = ObjMap>>ObjectsFromPoint(X, Y)
			
		if  fr <> nothing then
			
  	               nbObjFr = fr>>count
				
				NumObj=0
				for  NumObj = 1 to nbObjFr            
                                         obj = fr>>item(NumObj)
					 NomObjet = obj>>name

                                         // Here I see if  it's a street

                               next NumObj

              end if // fr
    next y

next x

[/code]

Hi,

This looks like something I recently needed, finding street name from a given lat/long location. But I do not understeand your question (English is not my native language). Can you rephrase it please ?

Hi Wilfried,

Sorry, English is not my native language also. I am french and I work in Morrocco.

What I am looking for is a fast way to find all the streets of a map.
What I tried to do is to loop with all the couples of points in the screen
( X , Y ) and use Objectsfrompoint method.

I am looking at an article of Gilles KHOL posted is this forum.
( Reverse Geocoding , Another Method )

I think, it's a good way to find the solution.
If you find something thanks in advance for your help.

Thanks for your message

Delphine
