Universal Maps Downloader is a specialized Windows tool developed by Allmapsoft that allows you to automatically download small tile images from mapping platforms (such as Google Maps, OpenStreetMap, and Bing Maps) and save them to your PC for offline use.
You can download the program directly from the Allmapsoft Download Page. The free trial limits your zoom depth, but the full version can unlock deep precision mapping.
Here is a step-by-step guide on how to configure, download, combine, and view your offline maps. Step 1: Configure Your Map Task
When you open Universal Maps Downloader, you need to create a specific task file (saved as a .umd file).
Select Map Type: In the left-hand menu tree, choose the map provider and layout you need (e.g., Google Normal Maps, Satellite Maps, OpenStreetMap, or Bing Hybrid).
Name Your Task: Give your project a recognizable name in the “Task Name” box.
Define Coordinates: Enter the boundary coordinates of the geographic area you want to capture:
Left Longitude & Right Longitude (West values are negative, East values are positive).
Top Latitude & Bottom Latitude (North values are positive, South values are negative).
Set Zoom Level: Select your preferred precision. Higher zoom levels offer sharper details but create a much larger total file size.
Choose Save Path: Designate a folder on your hard drive where the downloaded raw image tiles will live. Start: Click the Start button to begin pulling data. Step 2: Combine the Downloaded Map Tiles
Because maps are pulled down as thousands of tiny separate image chunks (tiles), you must merge them together into a unified image file to make them viewable. Go to the top menu bar and select Tools. Click on Map Combiner. Open your existing .umd task file.
Click Combine to merge all the small tiles into one massive, seamless image (like a .bmp, .jpg, or .tif file). Step 3: View or Export Your Offline Maps
Once combined, there are a few convenient ways to actually read and interact with your offline files:
Built-in Map Viewer: Go to Tools > Map Viewer and open your task file to scroll and zoom through the map directly inside the software.
Export to Mobile Apps: To use these maps on an Android or iOS device while traveling, navigate to Menu > Export to MBTiles database.
Using on Android (RMaps/OruxMaps/Locus Map): Once exported as an .sqlitedb file, you can copy the file onto your smartphone’s storage directory (such as /sdcard/rmaps/maps/) to view detailed topography or satellite layers completely without cellular data. Pro-Tips for Managing Interrupted Tasks
Resuming Downloads: If your internet drops or a download fails halfway through, simply reopen the software, click Open Task…, select your broken task file, and hit Start without changing any coordinate or zoom settings. It will seamlessly pick up right where it left off.
Zoom Limitations: Note that the trial version caps your maximum precision at zoom level 13. Upgrading to the registered version unlocks high-precision imagery up to zoom level 21. If you want, I can help you with:
