Capture Areas and floors on site

Areas of Interest are normally drawn in the browser, by clicking on the image. You can also capture them by walking the venue with your phone, which is the better answer for a layout that is not on any picture.

This is field editing, and it works on a Map you own, from the app.

When it is worth it

  • A temporary layout. Stalls, marquees and stages that are put up for the weekend and are on no plan.
  • A boundary you cannot see from above. Anything under tree cover or a roof.
  • Floors. Standing in a building and capturing each storey is much easier than deriving altitudes from drawings — see add floors to an Area.

When it is not

  • The shape is visible on your image. Clicking four corners in a browser is faster and more precise than walking them.
  • You are indoors and capturing an outline. A phone’s Position indoors is poor, so a walked boundary comes out ragged.
  • The Area is small. A few metres of position error matters much more on a ten-metre bar than on a hundred-metre field.

How it works

  1. Open the Map in the app and enter field editing. It explains itself the first time: walk the venue and capture geometry from your phone’s GPS.
  2. Tap ＋ New area and pick a shape under WHAT ARE YOU MAPPING? — Circle, Polygon or Rectangle. The same three as the browser.
  3. Walk it. A circle wants you at the centre; a polygon wants you at each corner, standing still for a moment at each.
  4. Everything you have captured is listed under ON THIS MAP, so you can see what is done and what is still a draft.
  5. When you are finished, review and submit: the review screen asks you to name each Area, and says plainly that nothing is posted until you commit.

Drafts, and the one thing that is not a draft

Areas and floors wait in a draft until you review and commit them, marked DRAFT in the list. That is deliberate: you can walk a whole site, get it wrong, and throw it away without ever having published anything.

⚠️ Anchor Points are the exception — they apply immediately. Calibration is what keeps the Map usable, so an anchor edit is not held back. That means a bad anchor captured on site is live at once; check the Calibration Quality figure afterwards. See capture anchors on site.

Editing what is already there

Field editing is not only for new things. Tap an Area’s row in the list, or tap inside it on the map, to recapture it — useful when a layout has moved since last year and you are standing in the new one.

Afterwards

Come back to the browser to finish the parts a phone is bad at: naming, icons, colours, the announced-or-quiet choice and label visibility. Walking gets you the geometry; the editor gets you the rest.
