Electronic Navigational Chart Data Handler Extension for ArcView 3.x NOAA Coastal Services Center

Electronic Navigational Chart Data Handler for ArcView

ArcView 3.x Problems and Solutions

It should be noted that the NOAA Coastal Services Center created the ENC Data Handler using software originally developed by the Environmental Systems Research Institute (ESRI). Certain ENC files, particularly ones that have been recently updated, will not convert due to file inconsistencies. Below, you will find a list of those ENCs. If you encounter others that do not convert, please let us know so that we can post them to this Web page.

The NOAA Coastal Services is currently working on a tool that will enable ArcGIS users to quickly install the S-57 Data Model and other components so that ENCs can be converted in the ArcGIS 8.3 environment. The executable should be available from this Web site by late Winter 2004.

This error occurs when trying to convert the ENC using the Data Handler.

A patch is now available that allows the complete conversion of these cells. Replace the existing enc2shp.dll found in the ESRI\AV_GIS30\ARCVIEW\BIN32\ folder with the patch (it may be a good idea to make a copy of the original enc2shp.dll file before replacing it with the patch file).

* It is important to note, however, that several of these cells also have a problem displaying the associated shapefiles correctly. See below for a way to manage this problem.

The "Depth_area_polygons" and "Depth_contours" shapefiles appear to possess errors and hinder the proper display of the ENC. As a result, most of the themes are located in the upper right hand corner of the view and a line extends across the entire view extent. Certain Arcview functions will cause the application to close if performed after the view is created. Zooming in on the view using the "magnifying glass" button, for example, will cause the application to crash.

If the "Depth_area_polygons" and "Depth_contours" themes are deleted immediately after the conversion, however, the rest of the themes should be displayed correctly and all Arcview functions (including the zoom tools) will work properly without causing the application to crash.

At this time, the "Depth_area_polygons" and "Depth_contours" shapefiles will not be able to be viewed properly for these cells. We are currently investigating the source of this error and will post any updates on this page as progress is made.

Application freezes after conversion

This error occurs shortly after the conversion of affected cells. A prompt with the option to create a new view may be presented after conversion, but the application freezes once the view selection box appears.

The cause of this problem is unknown at this time. We are currently investigating this error and will post any updates on this page as progress is made.
