Optionally override the animation easing to show or hide the toasts. Default is swing. swing and linear are built into jQuery. Use the jQuery show/hide method of your choice. These default to fadeIn/fadeOut. The methods fadeIn/fadeOut, slideDown/slideUp, and show/hide are built into jQuery. Rather than having identical toasts stack, set the preventDuplicates property to true. Duplicates are matched to the previous toast based on their message content. Control how toastr interacts with users by setting timeouts appropriately. Visually indicate how long before a toast expires.

    Earth Engine API

    Earth Engine API

    Python and JavaScript bindings for calling the Earth Engine API

    The Earth Engine API provides Python and JavaScript client libraries for Google Earth Engine, a planetary-scale geospatial analysis platform. With it, users compose lazy, server-side computations over massive catalogs of satellite imagery and vector datasets without handling raw files locally. The API exposes functional operators for map algebra, reducers, joins, and machine learning that scale transparently on Earth Engine’s backend. Developers authenticate once, work interactively in notebooks or the Code Editor, and export results to Cloud Storage, Drive, or asset collections. Visualization helpers render tiled layers and charts so analysts can iterate quickly on workflows like land-cover mapping, change detection, or time-series analysis. By combining petabyte-scale data with concise functional transforms, the API turns complex remote-sensing pipelines into reproducible scripts that are easy to share.
