This app serves as a mobile friendly version of the Mid-Atlantic Ocean Data Portal’s “Marine Planner” GIS web app, developed by the Mid-Atlantic Regional Council on the Ocean (MARCO). Visit www.portal.midatlanticocean.org to use the web app. Map: The map displays all of your active layers. You can view each layer’s description, legend, and more. You can also deactivate, reorder, change the opacity of, and toggle the visibility of each layer while viewing the map and see your changes instantly. Enabling the tap function on the map lets you view information about layers’ features at the tapped location. Each informational popup is draggable; Customize the screen to your liking! Layers: Explore thousands of layers by browsing various themes or performing a search, either across all layers or within your selected theme. Tap a layer to preview it individually and view its information. You can also activate a layer to add it to your Map or add it to your favorites to access it later. Some layers have specific functionality: A slider layer may let you change a layer’s appearance based on the month or year, for example. Preview: Select a layer in the Layers tab to view a map preview of that layer. In this focused view, you can view an individual layer’s source, description, metadata, and tap to view feature information, just like in the main map. You can also choose to view it alongside your other layers by activating it or add it to your favorites. Actives and Favorites: View your active and favorite layers on their own screen through the Preferences page. You can also choose to bookmark these pages in your Preferences to add them to your navigation bar for easier access. These pages provide an easy way to reorder, preview, favorite/unfavorite, and activate/deactivate your saved layers.

AGU Events's advantage is ratings volume (553 vs 8) and device support (3 vs 1). On price, ads and in-app purchases there is nothing between them.
