Map Management

This page explains how to upload and manage custom maps.

If you are unsure where to assign a map

If it is unclear how event-level maps and category-level maps relate to each other, start with Understand the event structure.

Custom maps are optional

If you do not set a custom map, NaviTabi uses the default background map. In Japan this is the Geospatial Information Authority map, and outside Japan it is OpenStreetMap.

Supported format

Format	Description
KMZ	A ZIP package that contains KML and image tiles

File size limit

You can upload KMZ files up to 8 MB. When uploading from the web, 5 MB or less with tile size 512 × 512 px is recommended.

Upload a map

Smartphone App

From the menu on the Manage screen, choose Raster Map Management.

1. Tap the + button
2. Choose how to upload:
   • Import KMZ File - Select a KMZ file stored on the device
   • Create with Calibration Wizard - Generate KMZ from an image
3. Enter the map name and copyright credit
4. When the upload finishes, the map is added to the list

Web

Upload from Map Management at /mypage/maps in My Page.

1. Select a KMZ file in the Import KMZ section
2. Enter the map name and copyright credit
3. Check the preview
4. Click the upload button

On the web, you can also replace the KMZ file of an existing map.

Calibration wizard

You can create a KMZ file from a paper map or a scanned image.

Steps

1. Choose an image - Select a map image from the device photo library or files
2. Register four control points - Match a point on the image with the same point on the real map
   • Tap a point on the image and register it
   • Tap the same place on the base map and register it
   • Repeat this four times
3. Check the preview - The calibrated result is shown over the base map. Use the opacity slider to check alignment
4. Export - Save as a KMZ file and upload it directly

How to improve accuracy

Distribute the control points near the four corners of the map. If the four points are too close together, the conversion becomes less accurate.

Edit and delete maps

Edit

For an uploaded map, you can change:

• Map Name
• Copyright Credit shown on the map
• Replace the KMZ file by importing a new file or recreating it with the wizard

Preview

If you open the preview from the map list, the map is shown over the base map. You can adjust opacity to confirm the alignment.

Delete

To delete a map, select it from the list and run delete.

Maps assigned to events cannot be deleted

If a map is currently assigned to an event, first change the map setting in that event and then delete it.

Assign a map to an event

Choose the map to use from Background Map in the event edit screen.

Option	Description
Default Map	Standard tile map. The most suitable map is chosen automatically by country
Smartphone Map	Shows only the default map provided on the device
My Maps	Custom maps you uploaded
Public Maps	Maps published by other organizers

You can also assign a different map for each category. Category-level map settings take precedence over the event-wide setting.

If you are unsure whether to set the map at the event level or category level, also see Understand the event structure.

KML vector overlays

In addition to a KMZ image map, you can display vector overlays from a KML file, such as polygons and polylines. This is useful for showing out-of-bounds areas or reference routes.

KML files are configured per course from the course edit screen. They cannot be set for the whole event at once.
