This repository contains a collection of Imagery Explorer web applications developed by Esri's ArcGIS Living Atlas team.
- Getting Started
- Landsat Explorer
- Sentinel-2 Landcover Explorer
- Sentinel-1 Explorer
- Sentinel-2 Explorer
Before you begin, make sure you have a fresh version of Node.js and NPM installed. The current Long Term Support (LTS) release is an ideal starting point.
To get started, clone this repository (or your fork) to your local machine:
git clone https://github.com/Esri/imagery-explorer-apps.gitNavigate to the root directory of the project and install the necessary packages (dependencies):
npm installThe Landsat Explorer app offers an intuitive user experience, it leverages a variety of ArcGIS capabilities to explore and begin to unlock the wealth of information that Landsat provides.
- Visual exploration of a Dynamic global mosaic of the best available Landsat scenes.
- On-the-fly multispectral band combinations and indices for visualization and analysis.
- Interactive Find a Scene by location, sensor, time, and cloud cover.
- Visual change by time, and comparison of different renderings, with Swipe and Animation modes.
- Analysis such as threshold masking and temporal profiles for vegetation, water, land surface temperature, and more.
Before running the application, update the LANDSAT_SERVICE_PROXY_URL_DEV and LANDSAT_SERVICE_PROXY_URL_PROD in the .env file to use the URL of your service proxy for Landsat Level-2.
# Service proxy URL for Landsat-Level-2 in development environment
LANDSAT_SERVICE_PROXY_URL_DEV = https://dev.landsat.service.proxy.url
# Service proxy URL for Landsat-Level-2 in production environment
LANDSAT_SERVICE_PROXY_URL_PROD = https://prod.landsat.service.proxy.url
# Specifies the service tier for the application, either development or production
# This is used to determine which service proxy URL to use
SERVICE_TIER = developmentTo run and test the app on your local machine:
npm run start:landsatTo build the app, you can run the command below, this will place all files needed for deployment into the /dist/landsatexplorer directory.
npm run build:landsat- Landsat Level-2 archive available in Living Atlas
- Landsat Explorer: Earth Science and Observation for All
- Landsat Level-2 RFTs: Raster Function Templates of the Landsat Level-2 service for the Raster Functions that are utilized by the app.

Land use land cover (LULC) maps are an increasingly important tool for decision-makers in many industry sectors and developing nations around the world. The information provided by these maps helps inform policy and land management decisions by better understanding and quantifying the impacts of earth processes and human activity.
The Sentinel-2 Land Cover Explorer app provides dynamic visual and statistical change by comparing annual slices of the Sentinel-2 10m Land Use/Land Cover data as you explore the map.
- Visual change analysis with either ‘Step Mode’ or ‘Swipe Mode’
- Dynamic statistical change analysis by year, map extent, and class
- Filter by selected land cover class
- Regional class statistics summarized by administrative boundaries
- Imagery mode for visualization and comparison of the source imagery
- Select and dynamically change imagery renderings
- Data download for offline use
To run and test the app on your local machine:
npm run start:landcoverTo build the app, you can run the command below, this will place all files needed for deployment into the /dist/landcoverexplorer directory.
npm run build:landcoverSentinel-1 SAR imagery helps to track and document land use and land change associated with climate change, urbanization, drought, wildfire, deforestation, and other natural processes and human activity.
Through an intuitive user experience, this app leverages a variety of ArcGIS capabilities to explore and begin to unlock the wealth of information that Sentinel-1 provides.
- Visual exploration of a Dynamic global mosaic of the best available Sentinel-1 scenes.
- On-the-fly multispectral band combinations and indices for visualization and analysis.
- Interactive Find a Scene by location, sensor, time, and cloud cover.
- Visual change by time, and comparison of different renderings, with Swipe and Animation modes.
- Analysis such as threshold masking and temporal profiles for vegetation, water, land surface temperature, and more.
Before running the application, update the SENTINEL1_SERVICE_PROXY_URL_DEV and SENTINEL1_SERVICE_PROXY_URL_PROD in the .env file to use the URL of your service proxy for Sentinel-1 RTC.
# Service proxy URL for Sentinel-1 in development environment
SENTINEL1_SERVICE_PROXY_URL_DEV = https://dev.sentinel1.service.proxy.url
# Service proxy URL for Sentinel-1 in production environment
SENTINEL1_SERVICE_PROXY_URL_PROD = https://prod.sentinel1.service.proxy.url
# Specifies the service tier for the application, either development or production
# This is used to determine which service proxy URL to use
SERVICE_TIER = developmentTo run and test the app on your local machine:
npm run start:sentinel1To build the app, you can run the command below, this will place all files needed for deployment into the /dist/sentinel1explorer directory.

Sentinel-2 multispectral imagery helps to track and document land use and land change associated with climate change, urbanization, drought, wildfire, deforestation, and other natural processes, disasters, and human activity.
Through an intuitive user experience, this app leverages a variety of ArcGIS capabilities to explore and begin to unlock the wealth of information that Sentinel-2 provides. Some of the key capabilities include:
- Visual exploration of a Dynamic global mosaic of the best available Sentinel-2 scenes.
- On-the-fly multispectral band combinations and indices for visualization and analysis.
- Interactive Find a Scene by location, sensor, time, and cloud cover.
- Visual change by time, and comparison of different renderings, with Swipe and Animation modes.
- Analysis such as threshold masking and temporal profiles for vegetation, water, and more.
