CT ECO includes two types of online reference documents that describe the information available in CT ECO. These guides are intended to help you understand how to use a particular map, map theme, or data layer.
CT ECO Data Guides provide basic information including a description, purpose, use limitations, data date, and a link to GIS metadata for technical documentation of the underlying data source. CT ECO Resource Guides are pdfs that more thoroughly describe the resources being mapped and include more information than the related Data Guides.
We welcome guest writers for Data Guides and Resource Guides. Please contact us at clear@uconn.edu.
Refer to CT Digital Aerial Datasets for a list and brief description of orthophotography available in CT ECO.
