How to import aerial images and set map overlays
Posted on Categories Custom Maps
In addition to the built-in maps, you can add custom maps to QubiMap, including online maps and aerial images. Currently, the supported aerial image formats include JPEG, PNG, TIFF, and IMG.
This article describes how to import aerial images and set map overlays.
1. Create a custom map layer
On the main UI of QubiMap on your PC, Choose [Custom Maps] > [Custom Map Management].

In the [Custom Map Management] dialog box, click [Add] and select [Add Custom Map] from the drop-down list. In the dialog box that appears, set the parameters and click [OK].

★ Parameters:
① Map ID: a unique ID number assigned to each custom map, ranging from 200 to 999.
② Map Name: the name of the map displayed in the custom map list.
③ Max Level: the highest display level of this map. Set a value higher than the actual level of the aerial images.
④ Projection Type: Select [Mercator (Global)]. It must match the projection type of the base map to prevent misalignment.
⑤ Time Type: Select [Single-Temporal] or [Multi-Temporal (Historical Images)] as needed. For more information about multi-temporal images, see the help document “How to add multi-temporal (historical) images to a custom map”.
⑥ For other parameters, you can keep the default values.
2. Import aerial images to the custom map
In the [Custom Map Management] dialog box, select the custom map and click [Manage Images].
You can import aerial images by using the following methods:

1) Determine Range via Lat-Long
If aerial images contain the lat-Long information in the upper-left and lower-right corners, you can use this method to import them. This method ensures precise alignment with the actual location.
In the [Custom Image Management] dialog box, Select [Import Image] for the [Operation Type] parameter, select [Determine Range via Lat-Long] for the [Import Method] parameter. Then, click the [Select] button next to the [Image Path] field.

The following options are available:
Select Image: Select a single aerial image to import.
Batch Select Images: Select multiple aerial images to import at a time.
Select Folder: Select all aerial images from an entire folder to import.
In this example, Select [Select Image]. Select the aerial image you want to import and click [Open].
The system automatically detects the display level based on the image resolution and lat-Long information in the upper-left and lower-right corners. You do not need to set the [Import to Level], [Upper Left Lat-Long], and [Lower Right Lat-Long] parameters.

Click [Start] to start importing.

After the import is completed, click [Yes].

2) Determine Range via TIFF/IMG File Coordinate Info
If aerial images contain the lat-Long information, you can use this method to import them. This method also ensures precise alignment with the actual location.
In the [Custom Image Management] dialog box, Select [Import Image] for the [Operation Type] parameter, select [Determine Range via TIFF/IMG File Coordinate Info] for the [Import Method] parameter. Then, click the [Select] button next to the [Image Path] field.
The following options are available:
Select Image: Select a single aerial image to import.
Batch Select Images: Select multiple aerial images to import at a time.
Select Folder: Select all aerial images from an entire folder to import.
In this example, Select [Select Image]. Select the aerial image you want to import and click [Open].
The system automatically detects the display level based on the image resolution. You do not need to set the [Import to Level] parameter.
Click [Start] to start importing.

After the import is completed, click [Yes].

On the main UI, switch to the custom map that is added, and you can view the imported aerial image.

3. Set an overlay layer
You can overlay the custom map onto a QubiMap built-in map. You can also overlay the road networks or other marker information onto the custom map. The projection types of the base map layer and overlay map layer must be consistent.
1) Set an overlay onto the custom map
In the [Custom Map Management] dialog box, select the custom map and click [Modify Map].

In the dialog box that appears, select [Use] for the [Overlay] parameter, and click the
button.
In the [Overlay Settings] dialog box, select the required overlay map layers in both [Small Font] and [Large Font] sections. In this example, a road network layer is selected. Additionally, you can set the color and transparency as needed. Then, click [OK].

On the main UI, switch to the custom map, and you can view the overlaid road networks.

2) Set a base map layer for the custom map
In the [Custom Map Management] dialog box, select the custom map and click [Modify Map]. In the dialog box that appears, select the required base map from the [Base Map] drop-down list, and click [OK].

On the main UI, switch to the custom map, and you can view the added base map.

4. Other methods to import aerial images
In addition to [Determine Range via Lat-Long] and [Determine Range via TIFF/IMG File Coordinate Info], you can also use the following methods to import aerial images to a custom map:
[Determine Location by Relation Point]: For more information, see the help document “Import custom maps by using relation points.”
[Import via Placemark Attachments Displayed on Map]: For more information, see the help document “Import custom maps by using placemark attachments displayed on the map.”
[Determine Upper Left Corner Location by Tile Number]: For more information, see the help document “Import custom maps by using tile IDs to determine upper left corner locations.”
