Marxan - Overview

Marxan is the most widely used decision-support software for conservation planning globally, and supports the design of cost-efficient networks that meet conservation targets for biodiversity.

Dataset providers:

Data processing Architecture

Marxan api architecture Data processing architecture

Datasets with a size lower than 5gb, will have a full automated pipe and be directly stored on the Geo-processing DB as part of the initial available data; this includes:

  • Protected Areas
  • Administrative regions
  • World Terrestrial Ecosystems

For those datasets that are over 5gb in terms of storage; a different approach is needed; this will be an on demand one, similar to what Andrew did for GBIF, and will have a pipe triggered by user needs trying to avoid as much as possible duplicities in storage:

  • GBIF
  • IUCN species range
  • Human footprint
  • Hansen forest cover

Database model

DB data model

Geoprocessing operations.

This are the main operations handled by the service

  • Format conversion
  • Re-projection
  • Validation
  • Geometry sanitization (Repair and simplification)
  • Spatial intersection
  • Area calculation
  • Split by property
  • Stratification; special spatial intersection

Vector tile service

  • Serve vector tiles from the db on the fly with a Redis cache upfront

For the future:

  • Raster management
