Agrimensor

Keep a field book of everything you find and give the land its names.

Collect the woods, stones, fruit and flowers of your world in a Field Book that remembers where and when you first found them. Then survey the land with a groma, the instrument of the Roman land surveyors, and give it field names that greet you when you walk in and appear on your maps. Your fields can be any shape you like: mark them chunk by chunk or walk their outline. Names can lie inside each other, just like real field names.

How it works

1. Field Book: Every player gets one on first login. It fills itself as you play: chop a log, mine a stone with the right tool, pick a flower or harvest a crop, and it is recorded. Crafting, trading and loot don't count.
2. First finds: Each entry remembers its first find with position, biome, day, date and the field name you stood in. Further finds are counted, together with every biome you found the entry in.
3. Groma: The Roman surveying tool. Right-click blocks to mark their chunks, or switch to the outline and set a survey point at every corner. Each point gets a ranging pole with a light beam, so you can see from afar where you measured.
4. Naming: Sneak and right-click to open the groma menu. It previews your area, shows which names it lies in or encloses and explains any conflict. Type a name and survey it.
5. Field names: Walk in and the name appears as a title, the enclosing name as subtitle. Hold the groma to see every field around you in its own colour, and carry a map to see them marked with a boundary stone.

Features

• Field Book with four chapters: wood, stone, fruit & vegetables and flowers.
  • Wood is grouped by species: log, wood and their stripped versions are one entry.
  • Entries come from tags, so woods, stones, fruit and flowers from other mods appear automatically, each mod in a chapter of its own.
  • Entries you haven't found yet show a "?", and hovering tells you what to look for.
  • A toast announces every new entry.
  • The finds belong to the player, not the book, so a lost book is no loss.
• Groma with two ways to survey:
  • Mark chunks: right-click to mark or unmark, marked chunks show as squares at your feet.
  • Walk the outline: ranging poles with light beams at every survey point, the first one green and the last one yellow. Clicking near the first point closes the outline, and edges that cross turn red.
  • Both can be mixed: walk the rough outline, then fix the edges chunk by chunk.
• Nested field names: a region, a field inside it and a plot inside that. A name must lie completely inside another one or enclose it.
• Field names everywhere:
  • Title when entering, or in the action bar, with a pause so it doesn't flash at borders.
  • Field borders in the world: every name in its own colour with its border, a light fill and its name floating above.
  • On vanilla maps with a boundary stone, the Roman terminus. Small names are left out on zoomed-out maps.
• Edit at any time: rename, add or remove chunks, or delete a name from the groma menu.
• In-game guide in the Field Book.

Built for servers

• Event-driven: Finds are recorded when blocks drop or are harvested, and field names are looked up only when a player enters another chunk. Nothing loads chunks, and all drawing in the world happens on the client.
• Ownership: Field names belong to whoever surveyed them. Only the owner and operators can rename, change or delete them. Surveying can be restricted to operators.
• Configurable: Field size, nesting depth, survey points, the closing radius, the Field Book on first login and map markers are set in a synced server config. Every player chooses how titles, light beams and field borders are shown.
• Datapack-friendly: The Field Book is built from tags. Datapacks can add, hide or merge entries, and /agrimensor catalog shows the result.
• English and German.

Coming soon

• Commands for operators to list, rename, delete and hand over field names.

Requirements

• Minecraft 26.3 with NeoForge 26.3.0.48-beta or newer.
