07-04-2017: Download speed seems to be ok now, or the throttling is less stringent.

07-04-2017: No more tiles seem to be missing now, like before.

I guess, and all end up at : all sites end up at the same IP address.

29-03-2017: or $z/$x.$y.png seem to be a working alternative for the a, b and c server.

29-03-2017: SSL Certificates at OpenTopoMap seem to have been improved and well signed now!.

Apparently the servers are behind a single load balancer executing the throttling… Therefore there is not much of an advantage of using multiple servers. The program ceases to download from the malfunctioning server.Īnother finding is that the number of retries increase with the number of servers (1, 2 or 3). If a tile cannot be downloaded after retries the request is handed to one of the other servers. Therefore the program executes up to 15 retries, with a back-off scheme (1 – 2 – 4 – 8 -16 – 32- 60 – 60 – 60 … seconds delay before subsequent retries). Apparently, some kind of throttling kicks in when doing a lot of requests. When downloading from OpenTopoMap often ‘503-Service Unavailable’ is encountered. Since the tiles are in place, taho.exe doesn’t download again

Restart taho.exe and create the maps with the same basemap and overlay map tiles.

Copy the OpenTopoMap tiles to the overlay directory taho.exe created.Download the OpenTopoMap tiles with TileDownloader.Directory structure has been created now. Start taho.exe with the base map and overlay map selected (doesn’t matter which, we use the overlay as placeholder).Roughly the process consists of following steps: However, when the tiles exist in the right directory, tiles are not downloaded again and the program starts building the maps (note: only when existing tiles are recent when older than a couple of days, taho starts downloading them again). Taho first downloads the tiles and then creates the maps (in my case: for OziExplorer). I myself use the downloader in combination with Taho.exe. Use for example OpenStreetMap export to select a bounding box and copy the coordinates.ĭelay is a kind of throttling: it is the delay between subsequent requests to the same server. Top left you can enter the lat and lon coordinates. The zoom level is the requested zoom level. At OpenTopoMap I found a lot of sea tiles non-existent, so I use following png (256×256): The default image is an image to be used if an image cannot be downloaded. The program automatically generates the subdirectories like 17/60475/54357.png. The output directory is the directory where the downloaded tiles are stored. During download they are replaced by the actual values. In the latter $z represents the zoom level, $x and $y the tile indices. You can enter the plain URL, like: or a custom one, like $z/$x/$y.png/ticket/1234 required for example for the Reit- und Wanderkarte site. For each server a thread is created, so three parallel downloads are executed. Start with java -jar TileDownloader.jar (yes, you need a Java JRE or JDK) I therefore wrote a Java program that is able to accept the non-signed certificates and can download from OpenTopoMap, Even worse, they use self-signed certificates. None of the downloaders I found can cope with these OpenTopoMap https tile servers. However, recently the tile servers of OpenTopoMap changed to https instead of http. Why then another OSM Tile Downloader? I particularly like the OpenTopoMap maps. Also, a lot of tile download programs exist, like: When making maps a lot of Open Street Map based tile servers exists with the base maps and overlay maps.
