Hi

Hi Sorry for later,
GDD Works well without any issue, it just need access to check if your connection is working or not.
In your case remove this "IsAvailableNetworkActive" function from GISDataDownloaderDownloader.cs:

- !IsAvailableNetworkActive() && from line number 768
- && IsAvailableNetworkActive() from Line number 801

Let me know the result

can anyone know what's the problem here !... it's appear when i try to calculate the optimized inputs by using (Gis Data Downloader) and then it doesn't work to download data. Thanks

 

Hi there,
You just need to the path where you want to download the data, then set the Zoom to 14 and Tiles count to (1,1), to start downloading click on Download Data button.
