Download Map Section

When you tap the Download Map Section button under the My Map Downloads section of the Layers panel, you are prompted to choose what sort of download you want.

Explorer Map & Data

The Explorer Map & Data option allows you to download segments of the Hema Explorer map layer. The interface is the same as the segment download interface you encountered earlier in using the app, during the First Time Startup of the app.

You can add and remove sections of the Hema Explorer map by tapping to add or remove the segments you want to download, or previously downloaded segments you now want to remove.

Other Layers

When you choose the Other Layers option from the Download Map Section button, you are presented with a list of map layers to choose from. The layers which appear here are those which are in the ACTIVE or AVAILABLE sections of the Layers panel.

Notice regarding status of satellite / aerial imagery with the app

Satellite or aerial imagery is not available for download within the app.
The satellite imagery content is sourced from a 3rd party, and the license by which we gain access to this content does NOT allow the content to be downloaded to a user device for offline use.
You can still view this content while online, however.
This is why the satellite content does not appear in the list of map sources to choose from when downloading areas for offline use.

For Your Information...

If you intend to download a map area for offline use, it is easier to center and zoom the area you are interested in before you select the area using the download for offline function.

Note!

Having multiple layers selected will only allow the max zoom level of the map source with the lowest maximum zoom level to be selected.
ie. if you have TWO sources selected and one has a max zoom level of 12, and one has a max zoom level of 16, and you have both selected, you will only be able to select 12 as the max zoom level for this operation.
It is recommended to only use ONE source at a time for area downloads.

Once you have chosen the layers required, you will see a screen showing a number of controls, as shown below:

Indicator showing the number of tiles, and the approximate amount of data required, to download the selected map layers, for the specified area, at the specified zoom level.

The larger the area, and the higher the zoom level, the bigger the download will be.

If this indicator turns red, the amount of data is too large to download in one go, and you will have to either:

The zoom slider determines the maximum zoom level for the map layer that you are downloading.

For Your Information...

If you have multiple map layers selected before entering this screen, you will only be able to set the zoom level slider to the maximum zoom level of the map layer which has the lowest maximum zoom level.
ie. if you have two map layers selected, and one has a max zoom level of 12, and one has a max zoom level of 16, you will only be able to set the Zoom Level slider to a value of 12 on this screen.

Drag the red box around by it's corner handles to select the area that you wish to download.

Remember if the Size indicator turns red, you are either trying to download too large an area, or too high a zoom level, or both.

Tap the Cancel button if you change your mind, and do not wish to continue downloading.

Tap the Save button when you are happy with the settings you have on this screen. When you tap the save button, you will be prompted to give your saved map a name, and optionally add some notes for your reference.

It is recommended to give your maps at least a name which helps identify it, as shown in the example below. When it comes time to clean up old map downloads, or those no longer required, it is easier if you can easily identify the content from the list of downloaded maps.
