Convert ENC to DWG

ENC navigation chart to CAD DWG conversion overview and steps how to achieve it.

How to convert enc to dwg file

What is enc to dwg conversion, and is it even possible?

Exporting ENC content to DWG (a common format used in CAD software) is not a standard practice or a straightforward process due to the fundamentally different purposes of these file formats. ENC files are designed for maritime navigation with specific data and structure, while DWG files are used for general CAD applications.

However, if you need to convert ENC content to DWG, it would likely require a multi-step process involving specialized conversion software or services. It might result in data loss or functionality due to format differences.

About maritime navigation ENC files

ENC files are used in Electronic Navigational Charts (ENC) for maritime navigation and are a crucial part of Electronic Chart Display and Information Systems (ECDIS) used on ships. Converting these files may be necessary for coastal development projects, harbor design, or other land-based engineering projects.

TRANSAS Navi-Sailor, Raymarine's navigation systems, and Furuno's ECDIS solutions are examples of popular ECDIS and marine navigation software systems that use the ENC file format.

Why even attempt to convert enc to dwg?

The need for such a conversion could arise when maritime data is required for coastal development projects, harbor design, or other land-based engineering projects where CAD software is used. In such cases, converting maritime charts into a format compatible with CAD software could help integrate sea navigation data with land-based design plans. However, this is a niche requirement and not a common practice in either maritime navigation or standard CAD applications.

Converting enc to dwg

Exporting Electronic Navigational Chart (ENC) data to DWG format is a complicated process, primarily because of these formats' different natures and purposes. ENC files are used for maritime navigation with specific standards and formats (such as S-57), whereas DWG is a common format for 2D and 3D design data in CAD software.

This process requires an in-depth understanding of both maritime chart data and CAD systems. Furthermore, due to the complexity and potential for data loss or misinterpretation, such conversions are typically undertaken by professionals in fields like maritime engineering, coastal development, or naval architecture.

Here's a general outline of how the enc to dwg conversion process might be approached:

Obtain source of ENC data

First, collect the ENC data, typically in S-57 format, the standard for digital nautical charts.

Find and use GIS software to read .enc files

Given the significant differences between ENC and DWG, you would require specialized software to interpret ENC data and translate it into a format that CAD software can read. This conversion might require custom solutions or tools created for particular professional needs since no direct, industry-standard tool exists. A few examples of software that could accomplish this task are GIS (Geographic Information System) tools that can handle S-57 format, such as QGIS or ArcGIS.

Navigation chart to cad conversion process

Use GIS software to open the ENC file. Then, save the data in a more CAD-friendly format by using the export or conversion feature of the software to export it in DXF (Drawing Exchange Format). Once the data is in DXF format, it can be opened and saved as DWG in a CAD program such as AutoCAD.

Limitations of enc to dwg conversion

ENC files contain specific maritime navigation information that may not translate directly into CAD environments. While basic geographical and structural data will likely be retained, specific navigation details may be lost or altered during the conversion process.

Simply put, it is impossible to convert ENC to DWG directly.
Thus, there is no so-called enc to dwg converter or a free online .enc to .dwg converter.
