From the LOWI airport (Innsbruck) there is a nice route that connects it with LIME passing through the Alpine area of the Dolomites, then takes a turn on the city of Verona (The city of Romeo and Juliet) and finally lands in LIME. This route is described by a file created with the FGFS Route Manager, the file has been inserted in the GIT, and then just type: | From the LOWI airport (Innsbruck) there is a nice route that connects it with LIME passing through the Alpine area of the Dolomites, then takes a turn on the city of Verona (The city of Romeo and Juliet) and finally lands in LIME.

The program starts downloading almost 200 images of 2K pixels in about twenty blocks of process. If now we want to make everything faster we can insert the turbo: | The program starts downloading almost 200 images of 2K pixels in about twenty blocks of process.

With this option the download speed increases by 2-10 times as we have authorized Julia to use up to a maximum of 10 CPUs (if any) of the PC. Thinking your system is slowing down? No, it doesn't slow down, you can continue to use FGFS without noticing anything, unless your system is old and maybe with a 2 CPU processor from 10 years ago. | With this option the download speed increases by 2-10 times as we have authorized Julia to use up to a maximum of 10 CPUs (if any) of the PC.

In summary, this command indicates that we download an area with Orio Al Serio (LIME) in the center, for a radius of 100 nm at the resolution of 4K pixels per image, the -s parameter can vary from 0 (512 pixels) to 6 (32768 pixels) and, in this case, -s 3 means a 4K pixel image. | In summary, this command indicates that we download an area with Orio Al Serio (LIME) in the center, for a radius of 100 nm at the resolution of 4K pixels per image, the -s parameter can vary from 0 (512 pixels) to 6 (32768 pixels) and, in this case, -s 3 means a 4K pixel image. | ||
We can also change the image server, there is the ''' | We can also change the image server, there is the '''--map''' option followed by a number which is 2 for the US server (all the United States) or 3 for Spain. | ||
Finally, another useful option is | Finally, another useful option is --over followed by a number that defines how the program behaves when it encounters an image already loaded, for example: '''--over 1''' replaces the image it finds already inserted only if it has a smaller resolution of the new one. If, on the other hand, '''--over''' is not declared or is set to zero, the program does not download the image if it is already present. In this way it is possible to have differentiated areas in the resolution of the images. | ||
I hope with this I have explained this project and have given you the curiosity to try it. | I hope with this I have explained this project and have given you the curiosity to try it. | ||
