Hooray! Map Mavin has just released a new plugin for ArcGIS that allows users to seamlessly upload their layers directly from ArcMap into Map Mavin.
With the click of a button, your layers are transported to Map Mavin and immediately into a web map!
Simply download the plugin, click the dropdown in ArcMap that says Map Mavin, and click Open Map Mavin window. Once logged in, you click Upload to Map Mavin, which adds your layers to your layer tab and creates a web map for you. Layer symbology is also preserved!
