# Build Spaces

> Register buildings and floors in GeoSpace, upload a floor plan, and use two-point scaling to match the plan to real-world dimensions.

<Info>
  This page covers preparation in **GeoSpace**, our positioning infrastructure partner. GeoSpace setup must already be complete. (See [GeoSpace setup](/en/geospace/onboarding).)
</Info>

Building a space follows the order **building → floor → plan**. After uploading a plan, you set the **scale** so that pixels on the plan map to real-world meters.

## 1. Register a building

<Steps>
  <Step title="Open building registration">
    On the **Building list** screen, press **\[+ Register building]**.
  </Step>

  <Step title="Enter details">
    * **Building name**: for example, Onecheck Mart
    * **Pick the location on the map**: type an address and choose from the search results. You can also click the map or drag the marker.
    * **Address, latitude, longitude**: filled in automatically once you pick a location.
  </Step>
</Steps>

## 2. Register floors

<Steps>
  <Step title="Open floor work">
    In the building list, press **\[Floor work]** for the building.
  </Step>

  <Step title="Add a floor">
    Press **\[+ Add floor]**, fill in the following, and press **\[Add]**.

    * **Floor name** (for example 3F, B1, Room 622)
    * **Sort value**: positive for above ground, negative for below (for example 3, -1)
    * **Description** (optional)
  </Step>

  <Step title="Move on to plan placement">
    New floors appear in the list. Floors without a saved plan are marked **incomplete**; press **\[Place plan →]** to continue.
  </Step>
</Steps>

## 3. Configure the plan (scale)

A floor plan image **carries no real-world dimensions.** Scaling tells the system "this length on the plan equals this many meters," connecting the plan to real-world coordinates. Locators, zones, and positioning coordinates all sit on top of this value, so set it accurately.

<Steps>
  <Step title="Open plan placement">
    Press **\[Place plan →]** in the floor list.
  </Step>

  <Step title="Upload the plan image">
    Press **\[Image]** and attach the plan file (PNG, JPG, and so on). Use a layout that matches the actual space.
  </Step>

  <Step title="Set the scale with two points">
    Press **\[Set scale with two points]**, then on the plan:

    1. Click the **start point**
    2. Click the **end point**
    3. Enter the **real distance (m)** between them → **\[Apply]**
  </Step>
</Steps>

</Frame>

<Tip>
  Choose two points across a span **whose real length you know precisely** (wall to wall, column spacing — measured with a tape or laser measure). The span you click and the distance you enter must cover **exactly the same stretch**.
</Tip>

<Note>
  The **"plan width (m)"** shown after applying is not your input — it's the **full image width converted to meters**. If your two points sit inside the image edges (because of margins or where you clicked), the value can appear larger than what you entered. This is expected.
</Note>
