I have developed a web application for the FAA using Google Maps API to display a variety of data that we are processing here for the WAAS System.
One of the features of the map is the ability to display different contour levels which are displayed by creating a series of GPolygon objects. I have noticed as time has gone on that the drawing of these polygons has been taking more and more time - to the point now where the latest version is actually taking a noticeable amount of time to redraw the polygons. To illustrate this problem I have created two different websites. Both sites are using the same exact javascript files that I wrote to manage and display the data, the only difference is the API Version being loaded in the -script- tag in the HTML document. Google Maps Version 2.140 http://www.nstb.tc.faa.gov/sms14.html Google Maps Version 2.159 http://www.nstb.tc.faa.gov/sms159.html To demonstrate how the polygon redrawing has slowed down - click on the 'real-time' button on the upper right hand corner and start clicking on some layers that draw Polygons (RNP 0.3, RNP 0.1, LVNAV, LPV, LPV200). The polygons draw almost instantaneously on Version 2.140 - but watch how slow they draw on 2.159. The layers need to be drawn in a particular order - since GPolygons do not currently support Z-Indexs (as far as I'm aware) there is a function called that will redraw polygon layers to make sure they are stacked in the correct order. Anyhow I am just curious if anybody else has noticed this issue. --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Google Maps API" group.
