A map atlas is a single (usually big) image of a map. Cartograph Maps supports the creation of map atlases of up to 60000×60000 pixels<\/strong>. But keep in mind that such a big atlas requires around 30GB of RAM. An example atlas can be found here (245MB!, 30000×30000 pixels): http:\/\/www.cartograph.eu\/v3\/downloads\/misc\/map_atlas_example.jpg<\/a>.<\/p>\n\n\n\n

Map atlases can be created from loaded offline raster maps<\/strong> as follows:<\/p>\n\n\n\n

    \n
  1. Load <\/strong>the raster map (Mapsforge raster, MBTiles, RMap, etc.) into the map view<\/strong>.<\/li>\n\n\n\n
  2. Go to the Map manager <\/a>and click on the loaded (active<\/strong>) map.<\/li>\n\n\n\n
  3. Select “Create atlas<\/strong>“.<\/li>\n\n\n\n
  4. Select the region <\/strong>which should be covered by the atlas and confirm your selection by pressing the green “Ok” button.<\/li>\n\n\n\n
  5. Select a zoom level <\/strong>and the size of the atlas. The higher the zoom level, the more details are visible on the map.<\/li>\n\n\n\n
  6. Start the creation <\/strong>of the atlas. Depending on the atlas size and your available RAM memory size this can take several minutes<\/strong>.<\/li>\n<\/ol>\n\n\n\n

    How to create a map atlas from an online map, such as OpenStreetMap?<\/h2>\n\n\n\n

    First, use the Map tile downloader <\/a>and download the target region <\/strong>at the zoom level <\/strong>which you want to use for the map atlas. From the downloaded map <\/strong>you can then create a map atlas <\/strong>as described above.<\/p>\n","protected":false},"excerpt":{"rendered":"
