The Hudson River Watershed Alliance is proud to introduce the Hudson River Watershed Atlas, a regional online mapping service designed to enable users to visualize, explore, assess and better understand the natural resources and built systems of the Hudson River Estuary watershed. Maps are produced by regional tiles (in Adobe Acrobat, PDF format) that allow you to download to your computer and interactively work with over 28 Geographic Information Systems (GIS) layers and information sources. These layers can be all be turned on and off independently, allowing you to zoom to, customize and print countless variations and combinations, depending on your area and topics of interest.

Our goal is to provide you with a robust and portable map service, sort of a mini-GIS. And while we have included a virtual “kitchen sink” of available information layers for you to choose from, like a full GIS, they are not intended to be used all at the same time.

Many data layers can also be used in the Google Earth geobrowsing tool. Of the 28 layers found within the PDF maps, we have produced a subset (18) as KMZ files, for use within the 3D (terrain) and 4D (time sequences of multiple air photo imagery for various locations) of Google Earth. These 18 layers and their respective data sources are described and are accessible for download from within the Legend, Data Sources & KMZs (PDF).

In developing the Hudson River Watershed Atlas, we sought to strike a balance of creating the most robust product that we could, that would be useful and accessible to the widest range of stakeholders, without requiring enormous training, background or technical requirements. The Get Acrobat maps will perform best on computers that are relatively new (2-3 years old), with 2GB of RAM, using Adobe Reader version 8.1 or greater. The files tend to be large (2-15 mbytes) and it is strongly suggested to download the PDFs to your computer before opening.

This project has been funded in part by a grant from the New York State Environmental Protection Fund through the Hudson River Estuary Program of the New York State Department of Environmental Conservation
