Geospatial analysis for biodiversity

Geospatial methods provide the common frame in which species ranges, protected areas, ecosystem maps, rivers, roads, concessions and sourcing regions are combined. They make overlap visible, keep boundaries and their dates traceable, and decide how much detail can safely be published without exposing species or communities.

01In brief

The short answer.

Geographic information systems combine species ranges, protected areas, ecosystem maps, rivers, roads, concessions and sourcing regions in one frame. For biodiversity they show overlap with sensitive areas, model connectivity and corridors, keep boundaries and their dates traceable, and decide how much detail can be published safely.

03Application

What geospatial information systems does here.

Geospatial information systems capture, store, analyse and present location-referenced data. They provide the common spatial frame for combining hazard, exposure and vulnerability information. In biodiversity and nature, climate and hazards and oceans and coasts, geospatial analysis identifies where hazards overlap critical assets and vulnerable populations. It supports location-based planning across infrastructure, health and finance. The canonical description is on the STEM Commons.

Overlap with sensitive biodiversity

Assets, concessions and sourcing plots are intersected with Key Biodiversity Areas, protected areas and threatened species ranges, with buffers and the age of each layer stated.

Connectivity and corridor analysis

Resistance surfaces with least-cost or circuit models identify corridors between habitat patches and the barriers that roads and settlements create.

Public-safe biodiversity maps

Sensitive locations are generalised to coarser cells or withheld according to sensitivity lists and community terms before any map is published.

04Key terms

Terms used on this page.

Each term as this page uses it. Where a standard-setting body defines the term, the wording follows that body.

TermDefinition
Key Biodiversity AreaA site contributing significantly to the global persistence of biodiversity, identified under the IUCN global standard.
Ecological connectivityThe unimpeded movement of species and flow of natural processes that sustain life, as the CMS describes it.
OECMAn other effective area-based conservation measure: a site outside protected areas that achieves long-term conservation.
05Geography

Landscapes and remoteness in Indonesia.

Mountain ranges, deserts, wetlands, glaciers and reefs, and how remote each division is from large cities, shown for Indonesia as an example geography for this subject.

The method as a run graph.

Data from the source register feeds the methods; calibration and an independent test gate the estimate and its limits; the decision stays with the competent authority.

08Validation

How results are checked.

Positional and attribute accuracy are checked against surveyed control points and reference datasets. Topology rules and metadata standards ensure consistency.

CheckHow it is done
Projection and alignmentLayers are reprojected to a common equal-area frame before any area is calculated
Boundary currencyProtected area and tenure boundaries are checked for date and legal status before overlap is reported
Disclosure reviewPublished resolution is checked against sensitivity rules and community terms

Errors in projection, scale and data currency propagate through analysis. Aggregation to administrative units can mask local variation.

10Stewardship

Who maintains the method.

Space and Earth Observation stewards geospatial information systems for the Consortium and reviews how it is applied across platforms.

12Questions

Questions and answers.

What are the limits of geospatial information systems in this field?
Errors in projection, scale and data currency propagate through analysis. Aggregation to administrative units can mask local variation.
How are results checked?
Positional and attribute accuracy are checked against surveyed control points and reference datasets. Topology rules and metadata standards ensure consistency.
Are the values on this page real?
The data names, roles and checks are real descriptions of practice. The canvas shows a design of the method's use, not a run; no result is reported here.
