This Chronology Viewer was created by the Cape Cod Commission, enabling users to view historic trends and aerial imagery from 1938 to 2020. It allows users to understand past land use and observe how the region has changed over time.
The application, first built by Cape Cod Commission staff in 2015, has been upgraded with a new look, updated data, and an easier-to-use interface.
The application’s slider feature allows users to compare changes over time – such as changes to road configurations, buildings, and the region’s ever-changing coastline.
The USGS images from 1938 to 2009 were made available to the Commission by the Cape Cod Conservation District. Commission staff worked with the images to fit them into modern mapping software. The modern images were part of Regional Aerial Data Acquisitions, managed and funded by Mass GIS and the Cape Cod Commission.
