I am using postgresql, php and xml to return the points from the data base. each polygon is in a line of the table in the data base. the GPolyline is drawing these polygons on the city. small cities I do not have problem, but great cities, with great amount of polygons are not drawing. The screen is gray and it does not return nothing. grateful.
See if the site is running correctly and that the app is very speedy -- if it is not speedy, it will not function properly. It doesn't sound like a coding issue or an api connectivity issue, it sounds more like a server speed issue. Keep me updated and I hope I can help.
to draw with gpolyline in small cities, it functions fast, the problem is in great cities, with some polygons inside of gpolyline. Will be some thing of xml, therefore use to search the information in postgresql? I am finding odd this.
