In September 2012 the Office of Coast Survey launched an experimental version of ENC Direct to GIS, which used an ESRI ArcGIS 10.0 server. We asked users to provide feedback on the symbology, accessibility, and attribution to charting data. That original version had been using the ESRI ArcIMS Server since inception in 2007.
Users suggested more than 50 improvements. Many of these recommendations are integrated into the current portal, which has been upgraded to ESRI ArcGIS 10.1 server technology.
Please note: the web portal has a new URL. Update bookmarks to encdirect.noaa.gov.
New ENC Scale Bands
The original web portal had four scale bands, where the approach and harbor scale bands were combined. This caused confusion as many of the features were duplicated. The new site has six scale bands that are displayed separately, depending on the resolution defined in the viewer.

Updated Frequently Ask Questions (FAQs) and How-To Pages
Based on customer input, we added new questions to the FAQ, specifically addressing the new look and feel of the viewer. The "how-to" procedures are updated to reflect improved map search function, extraction tools, and legend.
Point and Click Identify Object Function
The new "identify feature" function is a point and click away. In just a few seconds a box will appear that provides additional information about the feature being displayed. If more than one feature is available you can scroll through the identify box to gather information on each feature.

List of Additional Services
Navigational charting data is available for other GIS applications through different services. Examples include ESRI ArcMap using Rest URL map services, or Google Earth using the KML services available on the ENC Direct to GIS website.
