Earth observation on your desktop

Pick an area on a map, fill in a short form and press Run. Hiri finds the satellite imagery and elevation data it needs, so there is nothing to download or reproject first. Analyses run on your machine and nothing is uploaded.

Download for Windows
The macOS version, for Apple Silicon, is not released yet.
Requirements
Windows 10 or 11 on x64. It installs per user, so no administrator rights are needed. Nothing else to install: the analysis runtime is bundled with the app.
Not built
There is no Linux build. It is untested rather than impossible.

Nine questions it answers for you

Each guided analysis answers one question from an area and a date window. One screen serves both audiences: a short form with working defaults, and an Advanced section holding every threshold and weight behind the result.

Land

Urban growth
Where built-up land was gained or lost between two dates, in hectares
Green space
Vegetation extent, or how it changed between two dates
Land cover
Water, vegetation, built-up and bare soil, by index thresholds or K-Means, and how far it agrees with ESA's published map
Growing season
Start, peak, end, length and productivity, per pixel, over a year
Vegetation indices
NDVI, NDRE, RECI, MNDWI, NDBI or NBR as a continuous surface
NDVI for one image
NDVI for a scene you picked by name

Water

Water
Surface water extent, or how it changed, before and after a flood

Climate and hazards

Burn severity
Fire severity in four classes, against the published dNBR thresholds

Terrain

Terrain
Elevation, slope, aspect and hillshade. Bare-earth and about 10 m where United States coverage reaches, 30 m elsewhere

Imagery and elevation, fetched at run time

  • Sentinel-2 L2A

    Imagery through a public STAC API, read with windowed and overview reads, so a whole scene is never downloaded.

  • Elevation

    USGS 3DEP at about 10 m and bare earth across the United States, Copernicus DEM GLO-30 at 30 m elsewhere. Hiri picks one and names it in the result, because only one of the two includes buildings and tree canopy in its heights.

  • ESA WorldCover

    A published 10 m land cover map in eleven classes, added as a layer to compare your own classification against. Hiri fetches it rather than computing it.

  • Boundaries and place search

    An analysis can be cropped to the municipality you named rather than a rectangle around it.

  • Your own raster

    Imported as a layer once it passes validation.

Cloud cover is shown per scene before you pick one. When there is no usable imagery for an area and date, Hiri says so and suggests nearby dates.

Fifteen raster operations, for the steps in between

For what the nine analyses do not cover. They apply to any layer, including a GeoTIFF you imported.

Derive

  • Compute an index from bands you map
  • Combine up to four layers by weight

Classify

  • Threshold to a mask
  • Reclassify by ranges
  • Group similar pixels (K-Means)
  • Majority filter
  • Number connected patches
  • Trace to polygons

Compare

  • Difference two layers

Spatial statistics

  • Zonal statistics per class
  • Neighbourhood statistics
  • Clusters and outliers (local Moran's I)

Terrain and water

  • Cut and fill volumes
  • Flow direction (D8)
  • Flow accumulation

Formats your other tools open

Charts are drawn from the run's own numbers and coloured to match the map. Projects save and reopen with their layers, opacity, legends and past runs. Long jobs stream progress and cancel cleanly.

What each result does not tell you

Every analysis reports its limitations next to its numbers, along with the parameters and source scenes that produced them.

Two examples

  • Urban growth uses a spectral index that cannot distinguish built surfaces from bare soil, so growth is overstated where ground has been cleared but not yet built on.
  • Elevation comes from one of two models. Only one of them includes buildings and tree canopy in its heights, so the result names which one covered your area.

What it does not do

  • Not a GIS. No editing, digitising, topology, cartography or print layouts. Hiri produces layers and numbers to take into QGIS or ArcGIS.
  • No vector or network analysis: no routing, isochrones or travel-time catchments.
  • No offline operation and no telemetry.
