Maps & Floor Plans

Floor Plan A floor plan with asset positions and zone overlay.

TagFinder uses a hierarchical site model: Buildings > Floors > Zones (Geofences). This section explains how to set up your site for indoor positioning and zone-based tracking.

Site Model overview

Go to Site Model in the sidebar to see a summary of your buildings, floors, and geofences.

Buildings

Creating a building

  1. Go to Site Model > Buildings
  2. Click Create Building
  3. Fill in:
    • Name — e.g., "Warehouse A"
    • Address — street address (optional, for reference)
    • Coordinates — latitude and longitude of the building (used for map positioning)
  4. Click Save

Managing buildings

From the buildings list, you can:

  • View building details and its floors
  • Edit building name, address, or coordinates
  • Delete a building (this removes all its floors and geofences)

Floor plans

Each building can have multiple floors. Each floor can have a floor plan image that enables visual positioning of assets.

Adding a floor

  1. Open a building
  2. Click Create Floor
  3. Enter the floor name and number (e.g., "Ground Floor", floor 0)
  4. Click Save

Uploading a floor plan

  1. Open the floor you want to edit
  2. Click Upload Floor Plan
  3. Select a PNG or JPG image of your floor plan
  4. The image is stored and displayed as a map overlay

Tip

Use a clean, high-contrast floor plan image. Architectural drawings work well. Recommended resolution: at least 2000px wide for large buildings.

Calibrating a floor plan

Calibration maps pixel coordinates on your floor plan image to real-world meter coordinates. This is required for accurate indoor positioning.

  1. Open the floor and click Calibrate
  2. Define two reference points:
    • Click a point on the floor plan image and enter its real-world coordinates (x, y in meters)
    • Repeat for a second point — choose points far apart for best accuracy
  3. The system computes the pixels-per-meter ratio and rotation
  4. Click Save Calibration

After calibration, tag positions from the Wirepas mesh are plotted correctly on the floor plan.

Floor detail A calibrated floor: pixels per meter, image size, real-world dimensions, and the geofences drawn on it.

Geofences (Zones)

Geofences are named areas that can trigger alerts when assets enter or exit. They can be indoor (on a floor plan) or outdoor (on the map).

Types

Type Use case
area General-purpose zone
room Room within a building
dock Loading dock
aisle Warehouse aisle
rack Storage rack
building Entire building footprint
floor Entire floor

Creating an indoor geofence

  1. Go to Site Model > [Building] > [Floor] > Geofences
  2. Click Create Geofence
  3. Enter a name (e.g., "Cold Room A") and select a type
  4. Draw the zone boundary on the floor plan by clicking polygon points
  5. Choose a color for visual identification
  6. Click Save

Creating an outdoor geofence

  1. Go to Geofences in the sidebar
  2. Click Create Geofence
  3. Select Outdoor
  4. Click points on the map to define the boundary
  5. Enter a name and type
  6. Click Save

Managing geofences

From the geofences list:

  • Search by name
  • Filter by category (Indoor / Outdoor / All)
  • Edit boundaries, name, or type
  • Delete a geofence

Warning

Deleting a geofence also removes any alert rules that reference it. Check your alerts before deleting.

How positioning works

  1. Wirepas mesh tags report their position to the mesh network
  2. The system resolves tag positions using anchor node coordinates
  3. Positions are mapped to the calibrated floor plan
  4. Zone membership is computed by checking if the position falls within any geofence polygon
  5. If the tag enters or exits a zone with an active alert rule, a notification is sent
