Aerial View of Dutch History Brought to Life Through ERDAS APOLLO

June 29th, 2012 by Mladen Stojic, President of Hexagon Geospatial

Most nations warehouse a treasure trove of historic aerial photography and maps that provide the foundation for tracking significant changes over time.   In addition to providing a historical perspective on land and development changes, this data is also very relevant for citizens who want to see how their places of residence have changed over time.

In the Netherlands, Dotka Data maintains a large and growing collection of historical aerial photography and maps, reflecting more than 200 years of history.  The collection includes topographic maps from as far back as 1798, and aerial photographs taken for topological purposes from 1932 to current day.

Due to the age and breadth of the information in the collection, it offers a unique perspective on major changes and events such as the development of the Netherlands’ many polders, World War II and the post-war reconstruction and the urban expansion of the 1970s.

We recently announced that Dotka Data selected ERDAS APOLLO to manage its data in conjunction with an exciting new e-commerce project. Dotka is working with the Dutch newspaper AD to offer its readers an opportunity to view history on a more personal level – with current and 50-year old aerial photographs of their own homes.

In April and May, customers who maintain a subscription or purchase three newspapers will be granted access to a website enabling them to geocode their addresses to locate the relevant imagery, zoom in and out to view the details of their home and surrounding geography and order a free set of aerial images of their homes from 1960 and 2011. Historical maps from 1880-1930 and a 1980 aerial photograph will also be made available for purchase.

While ERDAS APOLLO is a renowned market-leading enterprise solution for managing and delivering massive amounts of geospatial data, in this instance it is also being leveraged as a commercial front-end application.

Dotka is using ERDAS APOLLO to support this initiative and ultimately the Dotka Shop – the new site for accessing these images. The site catalogues up to 60 terabytes of aerial photographs and maps from 1798 to present and delivers imagery to the e-commerce website upon request.

Through the special AD website, the multitude of AD subscribers will interact with the ERDAS APOLLO catalog. ERDAS APOLLO will send previews of the data to the website using WMS, and through WCS, collect the full high-resolution image to send to the printing shop.

For Intergraph, it is exciting to be playing a role in bringing GEOINT history directly to citizens’ fingertips in the Netherlands.
