Good morning. None of the solutions provided have worked for me, so I had to find an alternative solution to download the maps and then use them with LRRP.EXE. I remembered the days when I used OZIExplorer for offline navigation, and that there were applications that downloaded georeferenced maps so they could be used offline. LRRP stores the downloaded maps in the “Singles” folder, and when we check the properties of each image file, we see that they are 256x256 pixels and 8 bits. The size and bits can vary, and LRRP can use them, but it seems that with a larger size and more bits, the map flickers. LRRP does not process them at a good speed.
I have found free software that allows us to download maps of a specific area at various resolutions, giving us several zoom levels. The software is called TAHO. I believe the latest version is 4.12.
Instructions:
1. Open Taho and press the Bbox-tool button. A map opens in the browser (Chrome in my case).
2. Go to the area of the map you want to download, zoom in as much as you need to. The final result is not affected by this zoom, it is only to help you move around the map. Select “Select area” to mark a box with the part of the map you want to download.
3. In the black window at the bottom left, a link is created that you have to copy. Right-click on it and select “Copy” from the menu that appears.
4. Return to the Taho application and click “OK” in the Bbox-tool window. The coordinates of the desired map will be automatically pasted into the Taho application.
5. In Output, select how you want the map files to be organized and where they will be stored. Leave it on “Auto” or select the folder you want.
6. In the map sources section, I have only tried the “Mapnik(de)” source, which works correctly, and the first “Cicle” source, which downloads some pixelated images, making it unusable. Anyone who wants to try other sources is welcome to do so. I have not tried overlays, nor do I need calibration files. As it stands, the map shows street names just like Google Maps. That's enough for me.
7. In zoom level, I have marked all levels (I think it only downloads up to level 17). In Bits/pixel, set 8 (although I have tried 24 and 32 and it also works). In size, I have tried very large maps, but LRRP does not seem to process them quickly and there is flickering on the map. Finally, select “png.tile” in File type.
8. Click on “make maps” and the map download will begin. The larger the area, the more maps you will need to download. Don't try to download too much at once; you can download small maps of the area you need, and later combine folders from other maps so that lrrp can use them as needed.
9. If you get an error message at the end of the download, don't worry, I think it's because you've selected to download more zoom levels than the map server allows.
10. The downloaded map folder will have the name of the server from which you downloaded it. In my case, “Mapnik(de)”. The next step is to rename this folder “Singles” and place it in the same location as LRRP.EXE.
11. If you want to combine several downloads in the same folder, simply drag the new folders that are created into the main folder, paste them, and combine them with the ones already in Singles. Copy and combine everything.
