Spatial Research Suite · Mac & Windows

Serious analysis, made simple.

Everything in the suite serves one idea: you should be able to answer a question about a place without learning to code. Choose a study area, pick the steps and press run.

01 · Easy The point

No code, no setup

Pick a boundary from a list, choose what you want to see, press one button. R, Python and the engine are bundled, and your settings are remembered.

02 · Pipeline

Steps instead of scripts

What used to be an Earth Engine script is now a list. Click tools from a catalog of 60+, drag them into order and press run; each step hands its area to the next.

03 · Explained

Results you can understand

Every run comes back with a plain-English report: what was found, area by class, methods, datasets and references, ready to share or cite. See a sample.

04 · Classify

Land cover, made simple

Mark a few samples and let Random Forest, CART or SVM map the rest, with accuracy, area per class and change between years worked out for you.

05 · Analyse

41 cloud layers, land and sea

25+ spectral indices, terrain, climate, air quality, night lights and a coral and coastal module, each one a click away, with trends tested for you.

06 · Compose

Figures without design skills

Drop maps and charts onto a print layout with grid, scale bar, north arrow and legend already in place, then export at about 380 DPI.

This is what easy looks like

What used to take a script now takes a checklist.

Line up a land mask, a coral habitat mask and a health index, or any mix of 60+ tools, and press run. GIS4US does the Earth Engine work in order and tells you what it found, in words anyone can read.

01Pick from a list: no syntax, no scripts
02One date range for the whole chain
03A plain-English summary of every result
04Methods and references written for you

How it works

Three steps. No code. Same on desktop and phone.

01 · CONNECT

Link your Earth Engine

Sign in with the Google account that owns your Earth Engine project, only for the analysis step. It is a one-time step per device.

02 · CHOOSE

Pick a place and what to see

Choose a boundary from the list and a date range, then tick what you want: vegetation, water, land cover, trends. Press run.

03 · UNDERSTAND

Read the answer

Get maps, numbers and a plain-English summary. Share the report, compose a figure or export files for your GIS.

Your Earth Engine, your data

We built it so we can't see your work.

Your imagery, boundaries and analysis never leave your device: everything runs on your own Google Earth Engine account and quota. The desktop app only talks to us to verify a subscription by email, or when you choose to send feedback; your data is never part of either.

Desktop subscriptions are paid through Razorpay. The free Android app shows ads through Google AdMob, and Pro is sold through Google Play. Our privacy policy lists exactly what those services receive.

Built in the open, used in research

Easy doesn’t mean less rigorous.

GIS4US is built by Dr. Anant Kumar Pathak, a GIS and spatial-analysis researcher who wants the tools he uses to be open to everyone. The research pipeline behind the suite produced the analysis in a 2026 SSRN preprint on coral reef monitoring.

FAQ

Before you install.

Do I need to know how to code to use GIS4US?

No. That is the whole idea. You pick a place from a built-in list, choose what you want to look at and press run; there are no scripts to write and nothing extra to install. Students, teachers, field teams, NGOs and researchers can all use it from day one.

Can I really run Earth Engine on my phone?

Yes. GIS4US Field for Android runs spectral indices and classified maps on your own Google Earth Engine project, straight from the phone, with boundaries for 240 countries built in. You get the map, its legend and area per class without a laptop.

Are the GIS4US apps free?

Both are free to download and use. On Mac and Windows, every analysis is free on your own Earth Engine; a map image with its boundary exports free, Basic (₹299/month) adds data exports and reports, and Pro (₹799/month) adds the full PDF summary and workspace bundle. GIS4US Field for Android is free to install; an optional Pro upgrade (one-time or subscription, through Google Play) removes ads and unlocks exports and Pro tools.

Do I need a Google Earth Engine account?

Yes. Both apps run their analysis on your own Google Earth Engine project, under your own quota. Google offers Earth Engine free of charge for noncommercial and research use; commercial use needs a paid Earth Engine plan from Google.

Why does macOS warn me the first time I open the Mac app?

The Mac app is not yet notarized by Apple, so Gatekeeper asks you to confirm it once. Install it with the .pkg installer, open it, click Done, then go to System Settings → Privacy & Security and click Open Anyway next to GIS4US. After that it opens normally. Step-by-step guide.

Why does Windows warn me when I install the app?

The installer is not code-signed yet, so SmartScreen asks you to confirm it: click More info → Run anyway. Windows may also ask to let R through the firewall; the engine listens only on your own computer, so Allow or Cancel both work. Both prompts appear only once. Step-by-step guide.

Which computers does the desktop app run on?

Apple Silicon Macs (M1 or newer) with macOS 12 or later, and 64-bit PCs with Windows 10 or 11. Intel Macs, 32-bit Windows and ARM Windows are not supported yet.

Does GIS4US see my imagery or results?

No. Your imagery, boundaries and analysis stay on your device and in your own Earth Engine account. Analysis runs through a local engine locked to your own computer, so the packaged app can never send computation to a GIS4US server. The app contacts GIS4US only to verify a subscription by email or when you choose to send feedback; your data is never part of either.

How do I cite Spatial Research Suite?

Cite the software with its Zenodo DOI 10.5281/zenodo.22075123. The CITATION.cff file in the GitHub repository has the full metadata.
