Request access and we connect the model to your account.

Meta’s universal segmentation model, adapted to Mapflow workflows. Zoom 14 outlines land use, large fields and water; zoom 16 small fields and large buildings; zoom 18 farms and groups of trees; zoom 19 and up houses, trees and vehicles.

What you get

Polygons of whatever stands out at the chosen zoom.

Works best with

Any RGB imagery. Choose the zoom in the run form.

Usage examples

  • Outline objects no standard model covers

  • Pre-segment imagery for manual labelling

  • Explore a new area before choosing a model

Geo domain

Global

Method

Universal segmentation

GSD / zoom

z14–20

Note

This model is no longer a default model. It is available on request.

How it works

The “Segment Anything” (originaly introduced by Meta as universal segmentation model) is available as yet another experimental model in Mapflow. We adjusted it to Mapflow workflows to be used on a scale. There are the same steps required to launch this model:

  1. Select your data source

  2. Select your geographical area - either polygon, GeoJSON file, or your image extent

Yet there is one difference in the model workflow:

  • if you run this model using GTIFF file — the original resolution of the image will be used

  • if you run it via TMS (e.g. Imagery like Mapbox Satellite) — you need to select the Zoom level (image resolution) from the model options which will be used for the input

SAM options - zoom levels

Depending on the input resolution, the SAM model will interpret and generate different results. It can be empirically classified by mapping classes depending on the zoom levels as follows:

ZOOM LEVELS

SEMANTIC OBJECTS

14

Land use, large agri fields, forests, parks, fields, bodies of water

16

Small fields, large buildings, lawns, plots

18

Farms, buildings, groups of trees, etc.

19+

Houses, trees, vehicles, roof structures, etc.
SAM options - zoom levels

E.g. Result – SAM (zoom 14)

E.g. Result – SAM (zoom 16)

SAM options - zoom levels

E.g. Result – SAM (zoom 18)

SAM options - zoom levels

E.g. Result – SAM on aerial imagery (zoom 20), single trees. Some polygons are not very accurate and some target objects are missing, but the overall result is relevant and can be used for more accurate mapping.

SAM options - zoom levels

E.g. Result – SAM on aerial imagery (zoom 20), containers. Applicable to small similar-pattern objects, requires some manual filtering of the model’s output.

Note

SAM is not provided in Mapfow for QGIS list of default models, as the zoom options are not enabled in the current plugin’s design. Yet if you work in QGIS and want to try SAM there — send us a request and we will connect corresponding workflow scenarios with all zoom options specified.
