📍 Creating a Site

A site represents the geographic area you monitor (mangrove stands, reef sections, seagrass beds, etc.). Site geometry is required; other settings are optional.

Step 1) Site Info

  1. Select your Project.
  2. Go to Sites → Create Site (https://marimap.com/app/sites/new (opens in a new tab)).
  3. Fill Name, pick Site Type (Mangrove / Coral Reef / Seagrass / etc.), and Country (defaults to your org country).
  4. (Optional) Set Site ID — use Generate to auto-build an ID from organisation, project, site name, and ecosystem code.
  5. Add an optional Description.

Step 2) Draw or Upload Geometry

  1. In Site Area, choose Draw or Upload/manual.
  2. Draw a polygon on the map or upload GeoJSON/KML / paste coordinates.
  3. Confirm the area shown (minimum ~100 m²; very large polygons are rejected).
  4. Use the Layers button to toggle ecosystem layers for context.

Geometry is required to move past this step.

Step 3) Settings & Advanced (optional)

  • Governance / Tenure / Protection: management recognition, protection status, governance arrangement, land tenure, budget adequacy, enforcement capacity, formal management area name.
  • Baseline (ecosystem-specific):
    • Mangrove: historical presence, year lost, natural regeneration state, species present, species composition table (must sum to 100%).
    • Coral: reef zones, dominant substrates.
    • Seagrass: species present, continuity, min/max depth.
  • Cost & Privacy: total cost value + currency and Data privacy override (defaults to your organisation’s setting).

Good Practice

  • Keep geometry stable across time so trends stay comparable.
  • Store helpful context (access notes, tidal info, substrate) in the description.
  • If you change data privacy at the site level, all surveys created under it inherit that value unless a protocol overrides it.
