Step by step: from downloaded survey sheets to one joined village map
A simple walkthrough — collect your sheets from the Survey and Settlement portal, upload, auto-arrange, fine-tune the seams, and export one clean map.
Here's the whole flow, end to end, for someone who has just downloaded a village map from the Commissionerate of Survey and Settlement, Tamil Nadu.
1. Collect every sheet of the village
On the survey portal, download each sheet for your village. Keep all the pages together — if the village is split into S1, S2, S3, S4, make sure you have all four. Note the sheet numbers in the filenames; the tool can use them.
2. Upload them into the editor
Open the editor and drop in your PDFs. Each PDF page becomes its own movable piece. The app renders them at high resolution and auto-crops the printed frame around each sheet.
3. Auto-arrange by sheet number
If your filenames carry the sheet number (…S1, …S2, …S3, …S4), hit Auto-arrange. The pieces tile into a grid row by row — S1 top-left, S2 top-right, S3 bottom-left, S4 bottom-right — with a small overlap at each seam so the cropped borders meet.
4. Nudge and snap the seams
- Drag a piece near its neighbour; edge-snap guide lines appear when boundaries line up.
- Use the arrow keys for fine nudges (hold Shift for larger steps).
- Turn on white-to-transparent if a sheet's margin is hiding the map underneath.
- Rotate slightly if a sheet was scanned at an angle — rotation snaps to 15°.
5. Preview and export
Zoom out to check the whole village reads as one map. When you're happy, export a single high-resolution PNG, or a print-ready PDF fitted to A0–A4 with a live DPI estimate. Assembling and previewing are free; you only pay when you download the finished file.
