About GIS4US

GIS4US builds research-grade satellite analysis apps: Spatial Research Suite for Mac and Windows, and GIS4US Field for Android. Both run on your own Google Earth Engine, and a free knowledge hub explains every method they use.

Why we exist

The Earth is observed continuously from orbit, producing a freely available record of environmental change unmatched in human history. Yet for most of the people who could act on that record — ecologists, environmental researchers, planners, and conservation teams — it has remained out of reach, locked behind programming skills, costly licences, and heavy computing requirements. We built GIS4US to close that gap: to turn planetary-scale satellite analysis from a specialist craft into an everyday research tool.

What we do

GIS4US makes two apps and one library. With Spatial Research Suite on Mac or Windows and GIS4US Field on Android you can:

  • Classify land use and land cover with supervised machine learning and receive a formal accuracy assessment (overall accuracy and Kappa).
  • Track vegetation health and change using NDVI and dozens of other validated spectral indices.
  • Monitor water bodies, urban heat, and coral-reef health from multi-date satellite imagery.
  • Run change detection and trend analysis across years or decades, and export publication-ready maps, statistics, and charts.

Every workflow is method-based and documented, so results are transparent, reproducible, and defensible under peer review. The research pipeline behind the Mac suite is published on GitHub and citable through its Zenodo DOI. The Knowledge Hub and Resources explain the methods behind both apps, free for anyone.

Our expertise

GIS4US was founded by Anant Kumar Pathak, a researcher working at the intersection of geospatial science, remote sensing, and environmental sustainability. The apps grew out of applied doctoral research on coastal sustainability, where the daily reality of wrestling satellite data into usable evidence made the need for an accessible, rigorous tool unmistakable. That academic grounding shapes the apps: the methods, formulas, band configurations, and citations behind every analysis are published openly in our Resources library and Knowledge Hub, because we believe a research instrument should never be a black box.

Our commitment

We are guided by a simple conviction: better environmental decisions require better, more widely shared evidence. Everything we build is oriented toward stewardship, scientific rigour, transparency, and long-term ecological balance. We want the next generation of environmental stewards to be able to pick up powerful Earth-observation tools and start protecting the planet today.
