Technical note

N1 to DWG: what carries over and what does not

Geospatial coordinates are absolute positions on the earth, and they are large: a projected easting runs to six or seven digits, while latitude and longitude are small decimals. DWG expects a drawing laid out near its own origin in millimetres or inches. The geometry itself converts correctly, but it can land tens of kilometres from 0,0, or arrive at a scale where an entire county is forty units across. Zoom to extents first, then measure one known distance before dimensioning anything. N1 is made of pixels and DWG stores geometry, so the conversion traces the image into real lines, arcs and polylines. The result is editable in CAD: entities can be selected, snapped to and measured, rather than a bitmap wrapped inside a DWG container, which is what a viewer or a lightweight converter usually produces. It is still derived geometry, so expect contours rather than a structured drawing. Dimensions, blocks and meaningful layer names were never in the N1 to begin with.

Map Data Workflow

From map data to a working drawing

Converting N1 to DWG usually means handing GIS data to someone who works in CAD. reaConverter makes that hand-off without a GIS seat on either side, for one layer or a whole delivery.

  • Convert every layer in a folder to DWG with the same settings
  • Go the other way too, from DWG to Shapefile, when the GIS team needs the drawings back
  • Render the same data to PDF for a quick review copy
  • Pick up new data automatically with Watch Folders, or script the job from the command line

Everything runs on your PC, which matters for cadastral, utility and client data that should not pass through an upload form.

I previously used a similar program that stopped working, so I needed to find a replacement. reaConverter turned out to be the perfect solution—after reviewing the instructions on this page, I was able to convert DWG files immediately.

After nearly two years of relying on online converters, I finally installed standalone software. Why didn't I do this sooner? Now I can work completely offline — no more wasted time uploading/downloading or eating through my data allowance!

I typically avoid installing too many programs to keep my hard drive clutter-free, but constantly uploading/downloading files for conversion became too time-consuming. That's why I chose reaConverter when I needed to transform DWG files into readable PDFs—and it performs flawlessly!

FAQ

N1 to DWG Conversion

What are N1 files?

N1 is the file extension of products from Envisat, a large Earth observation satellite of the European Space Agency (ESA). The letters in the name stand for the satellite itself: N1 for Envisat-1, while products from the older ERS-1 and ERS-2 satellites in the same family use E1 and E2. A file of this type contains the measurements of one instrument for one pass over the Earth, for example a radar image from ASAR, a color image of the ocean and land from the MERIS spectrometer, or sea surface temperature from AATSR. It also contains a description of the product and its quality. Many such files still lie in scientific archives, and they are used for research on oceans, ice, vegetation, and the atmosphere.

What are DWG files?

DWG (which stands for "Drawing") is a proprietary format of AutoCAD, a program widely used for creating engineering and architectural projects. The format is also a default extension used by several other computer-aided design (CAD) pieces of software, including IntelliCAD, Caddie or DraftSight. DWG files contain complex design structures including several layers, which can be 2-dimensional or 3-dimensional.

Can reaConverter convert N1 to DWG?

Yes! reaConverter instantly converts .n1 to .dwg with perfect quality preservation. With its batch processing feature, you can convert multiple files at once in just a few clicks. You can even convert images directly from Windows Explorer using the right-click menu — fast and convenient.

What is reaConverter used for?

reaConverter is a Windows converter for 800+ formats, GIS data among them. For N1 to DWG it replaces the usual detour through QGIS, ArcGIS or ogr2ogr: add the files, pick the output format, and the whole batch converts offline.
