📍 Plot Map Editor Help

The basic workflow:

1. Upload your map image using MAPS
2. Draw outlines around each grave (or use Auto-Detect)
3. Assign plot codes to each outline
4. Click SAVE EDITS when done

What it does: Upload and manage your cemetery map sections.

• Upload new map images (PDF, JPEG, PNG)
• Switch between different sections
• Keep multiple versions
• Delete old versions
• Upload a satellite/aerial reference photo for the legacy map or any section (🛰️ Satellite button next to each map)

Automatically trace grave outlines from your map.

1. Make sure your map is uploaded
2. Click "Auto-Detect"
3. Leave it on Easy for a drawn plan (see below), or switch to Advanced to choose a method yourself
4. Click "Analyze" and wait 1-10 minutes
5. Review and click "Accept" or "Reject"

Easy and Advanced modes: Auto-Detect opens in Easy mode, which runs a fixed recipe that suits most drawn plans: Line tracing, plot map / schematic, with plot codes read by AI. Advanced lets you pick another map, a different method, a satellite/aerial photo or a one-off upload.

Two detection methods:

• Line tracing — the default. Follows the walls actually drawn on the map, so shapes are true to the plan. It works on scans and on photographs of a drawn plan, and is the better choice for any drawn map. Drawn plans only, not aerial photos. AI is used only to read the plot codes, and only if that box is checked.
• AI vision — asks an AI model to draw the outlines as well as read the codes. Models cannot place outlines precisely, so shapes tend to be simple rectangles that drift off the real boundaries. Use it only for satellite/aerial photos, where there are no drawn lines to trace.

Also read the plot codes with AI is a separate checkbox — leave it unchecked to get outlines faster with placeholder codes (AI-1, AI-2, …) that you fill in by hand.

The Auto-Detect button on the dashboard's Plot Map works the same way: line tracing for drawn maps, AI vision for satellite photos, PDFs and maps stored as an external link.

Attaching to plots you already have: If this map's plots were already imported (e.g. by CSV) before you ever ran detection, check "Attach to plots that already exist" in the results screen. A detected outline whose code exactly matches a plot already in your database gets its polygon attached to that existing plot instead of being skipped — the plot's status, owner and section data are left untouched. A code that doesn't match is skipped and reported rather than silently turned into a new plot, unless you also check "Also create new plots for any code that doesn't match".

If codes came back as placeholders instead of the real thing, use "Or paste ordered codes" first: paste your roster one code per line, in the same left-to-right/top-to-bottom order the outlines appear on the map, and it replaces every code (read or placeholder) with the real one before you attach.

Add real-world GPS coordinates to your map.

1. Click 3-4 reference points (building corners, known roads)
2. Enter their real-world latitude and longitude
3. System calculates GPS for every plot automatically

Walk to graves with your phone and record exact GPS locations.

1. Click "Field GPS Capture"
2. Open the link on your phone
3. Walk to each grave and tap to record location
4. Data uploads automatically

MAP (Eye icon): Show or hide the background map image
PLOTS (Grid icon): Show or hide plot outlines
GRID (Squares icon): Show or hide alignment grid
SNAP (Magnet icon): Auto-snap points to nearby corners/edges
SATELLITE: Show or hide an uploaded satellite/aerial reference photo, layered behind the map. Only appears once a satellite photo has been uploaded via MAPS; not available in Combined (multi-section) view, since there's no single backing image to layer it under.

Line up a satellite/aerial photo with your drawn plots. The photo is uploaded stretched to the frame by default, so click Position (next to the Satellite toggle) to drag the photo into place and use the zoom slider to scale it, then Save, Reset (back to centered, un-zoomed), or Cancel. This only changes how the photo is drawn — the uploaded image itself is never modified. Legacy map and each section map keep their own independent position.

See your edits and the original map side-by-side. Each side zooms independently. Perfect for quality checking your work.

Trim unwanted edges or brighten/darken your map. Use sliders to adjust brightness and contrast, or drag the dashed rectangle to crop.

1. Click MAPS → Upload your PDF or image
2. Click AUTO-DETECT
3. Stay on Easy for a drawn plan, or open Advanced and choose AI vision for a satellite/aerial photo
4. Click Analyze and wait (1-10 minutes)
5. Review the outlines on the map
6. Click Accept if it looks good
7. Adjust any wrong shapes using SELECT mode
8. Click SAVE EDITS when done

1. Click SELECT mode (usually already active)
2. Click the plot you want to fix
3. Red corner handles appear
4. Drag corners to the correct position
5. To add a corner: double-click an edge
6. To remove a corner: click it and press Delete
7. Click Done
8. Click SAVE EDITS

1. Use DRAW or RECT mode to create new plots, OR
2. Use SELECT mode and click a plot missing a code
3. In the floating panel on the right, click the code field
4. Type the code (e.g., "A-23")
5. Click Save Changes
6. Click SAVE EDITS at the top

Option A: Calibrate the map (quick)

1. Click MAP CALIBRATION
2. Click 3-4 reference points on the map
3. For each, enter real-world latitude and longitude
4. System calculates GPS for every plot

Option B: Walk with your phone (precise)

1. Click FIELD GPS CAPTURE
2. Open the link on your phone
3. Walk to each grave and tap to record location

Possible reasons:

• Your map is an aerial or satellite photograph, not a drawn plan
• Graves have dotted or dashed lines instead of solid boundaries
• The map has fold creases
• The section is too large

What to try:

• Make sure it's a drawn plan — a scan or a photo of a plan is fine. Line tracing can't read an aerial or satellite photograph, which has no drawn lines; use AI vision in Advanced mode for those
• If a brightly coloured illustration is rejected as a photo, tick This is a drawn map, not a photo in Advanced mode (Easy mode already does)
• Try a smaller section, especially if the map holds more than about 300 graves
• Use Crop/Adjust to brighten a dark/faded scan
• Map it manually using DRAW mode, or trace individual graves with WAND

Possible reasons:

• "Attach to plots that already exist" wasn't checked on the results screen
• The outline's code doesn't exactly match a plot code already in your database (a code that reads as a placeholder like "AI-1" will never match)

What to try:

• Check "Attach to plots that already exist" before finishing the run
• If codes came back as placeholders, use "Or paste ordered codes" to give them the real codes first, then attach

1. Click MAPS and confirm you've uploaded an image
2. Click the Map toggle (eye icon) to turn it on
3. Click "⊡ Fit" to zoom to fit

1. Did you click the green SAVE EDITS button?
2. Is "Unsaved changes" still showing? If yes, try again.
3. Check your internet connection
4. Try refreshing the page if it's stuck

Before you saved: Refresh the page. Your edits are lost but the old version comes back.

After you saved: It's permanently gone. Re-draw it or restore from a backup.
