Types if needed.Some of the maps are downloaded in full the first time you select them. Larger maps automatically download data on-the-fly as you scroll around the map. But if you are planning a trip outside an area of internet connectivity (or if mobile internet data is expensive), you should download the detailed coverage you need in advance. There are a number of ways you can do this:
Download a Package (For nautical charts or topo maps provided as a set of individual sheets, such as the Hema maps)
Scroll to view any part of your area of interest
Tap Maps
,
Digital Map Store. Tap Map
Types if needed.
Look for a listed item starting with "Package: ..."
When you tap that, it will download all the maps in the package
At a later time, you can click the Maps, Check for Map Updates menu command. This will ensure you always have a complete set of up-to-date charts for the area.
Along a planned route (for seamless topo maps)
Plan the route you are going to travel (See Routes)
Include any side trips or escape routes
Open the detailed map you want to download/activate.
Tap on any waypoint, and Route Operations.
Select "Download Map Along Route".
If the map is a DMS Selections map, you are prompted to activate that area of map, if needed.
Downloading a custom area (for seamless topo maps)
Using a small-scale basemap, create a route that encloses the area of map you want
Place the last waypoint close to the first one. It does not need to be exact, as the polygon is automatically closed
Open the detailed map you want to download/activate.
Right-click on a waypoint, and Route Operations.
Click Download Enclosed Map
If the map is a DMS Selections map, you are prompted to activate that area of map, if needed.
Downloading the whole map (for seamless topo maps)
Some detailed topo maps are extremely large (tens of GBytes), which is why we provide the route-based tools to enable you to easily download just the areas you need, without filling up your disk with data that you will never even look at.
However, some seamless topo maps are a more reasonable size, and there are times when it is convenient to have the whole map downloaded for use in the field. For example, search and rescue personnel may need a map of any part of their area at short notice.
In the map list, click the blue button beside the map you wish to download. If this feature is enabled for the map, click the Download Whole Map button.
This operation may take several hours. If you are using a laptop, it must be plugged in to the power supply.
Downloading all activated areas (for DMS selections maps)
If you have a map that was purchased by the square kilometer, and you have migrated your license from another computer, you can easily download all the areas of the map that have been activated.
In the map list, click the blue button beside the map you wish to download. If this feature is enabled for the map, click the Download Activated Areas button.
All the map data, once loaded, is cached for future off-line use. If you want to free up some of your device's memory, bring up the Map list, tap More Maps and All Maps. Use Map Types if needed to view different types of map. Decide which map you want to delete and tap the little blue button to the right of the map. Tap Delete Map. If the map is licensed, this does not delete the license. You can download the map again in the future and use it any time.
When you have loaded a new edition of a set of maps, and you want to remove the old edition, use the Maps, Remove Duplicate Maps menu command.
If you want to delete a whole set of sheet maps, it may be easiest to exit Memory-Map and use the Finder app to delete them manually from the Library area. In the menu, click Go, Go to Folder, and enter /Users/<username>/Library. Then click to Application Support/com.memory-map.macapp/DMS.
