This repository contains a collection of Imagery Explorer applications developed by the Esri's Living Atlas team.

Before we 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/vannizhang/imagery-explorer-apps.git

Navigate to the root directory of the project and install the necessary packages (dependencies):

npm install

The 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, you may need to create a proxy item for the Landsat-Level-2 service with your credentials embedded (Learn more about storing credentials with service item). Please note that the proxy items utilized by the application hosted on the Living Atlas server only allow usage from the Living Atlas domain.

Next, update the landsat-level-2 URLs in the config.json to use the URL of the proxy service you just created.

config.json:

{
    //...
    "services": {
        "landsat-level-2": {
            "development": "URL_OF_YOUR_PROXY_SERVICE_FOR_LANDSAT_LEVEL_2",
            "production": "URL_OF_YOUR_PROXY_SERVICE_FOR_LANDSAT_LEVEL_2"
        }
    }
}

To run and test the app on your local machine:

npm run start-landsat

To build the app, you can run the command below, this will place all files needed for deployment into the /dist/landsat directory.

npm run build-landsat

• Landsat Level-2 archive available in Living Atlas
