I am attempting to add code to QGroundControl to use NOAA Nav charts for the map display. We have updated UrlFactory::getTileURL() with a url to the NOAA tile services that looks like the following, http://tileservice.charts.noaa.gov/tiles/50000_1/2/2/1.png. From a browser this url executes and downloads a png image. If I use wget the url also succeeds and results in a downloaded png file. When run within QGC the result contains an html formatted reply that reads " This object may be found here " and QGC prints out a message that reads “tile request error “Problem with tile image””. I tried setting the QNetworkRequest object to “follow redirects”, but this also fails with numerous SSL errors. What am I missing? Appreciate any help.
@rickm thought I could follow up with you to see if you’ve had any success with this…we’re trying to do something very similar…
