Data Guides
![]() |
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 included in the Map Catalog, Thematic Map Viewers, Advanced Data Viewer, or Map Services. Data Guides may be accessed directly from the Map Catalog, Thematic Maps Viewers, Advanced Data Viewer, and Map Service sections of CT ECO. Listed below are all of the Data Guides in CT ECO. Each one provides basic information including a description, purpose, use limitations, data date, link to the related Resource Guide for a more thorough description, and a link to GIS metadata for technical documetation of the underlying data source. Refer to Connecticut Digital Orthophotography for a list and brief description of orthophotography available in CT ECO.
