Technical note

GVB to PNG: what carries over and what does not

GVB is not a map but a correction grid. Each cell holds the small offset needed to move coordinates from one datum to another, or the height of the geoid, the surface that turns a GPS height into a height above sea level. Survey and GIS software applies it silently during a coordinate transformation. Rendered as PNG, it becomes a smooth picture of those offsets, useful for documentation or teaching, while the transformation itself still needs the original GVB. GVB carries georeferencing: a coordinate reference system, and the real-world position and ground size of every pixel. PNG has nowhere to record any of that. The picture transfers intact, the location does not, so the output cannot be dropped onto a map afterwards without being placed by hand. Keep the GVB original if the data still has to go back into a GIS.

Map Data Workflow

Turn GIS data into something anyone can open

Not everyone who needs to see GVB data has GIS software. reaConverter renders it to PNG for a report, an email or a slide, and handles a whole folder in one run.

  • Render every file in a folder to PNG with the same size and settings
  • Set DPI and output dimensions before the run, not afterwards
  • Stamp a text watermark, such as a project name or a date, on every image
  • 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 design logos and need transparent PNGs for clients. reaConverter converts AI and EPS files to PNG with crisp edges and full alpha channel support. The batch processing saves me hours when I have to export dozens of variants. Absolutely essential for any graphic designer.

I love that reaConverter can convert PDF pages to individual PNGs. I used it to extract images from a scanned document – each page became a high-res PNG with zero loss. It's like magic, but it actually works every time.

I design stickers but could never cleanly resize my PNG logos without pixelation. reaConverter’s PNG-to-SVG tool keeps everything sharp—even when scaling up. My Etsy shop looks way more professional now!

FAQ

GVB to PNG Conversion

What are GVB files?

GVB is a datum grid shift file that follows the NTv2 (National Transformation version 2) model, created by the Geodetic Survey of Natural Resources Canada. Such a file helps convert map coordinates between two geodetic datums, which are different mathematical models of the Earth, so that old and new survey data line up correctly. It covers an area with a net of points and stores, for each of them, how far latitude and longitude have to be moved, usually with an estimate of the accuracy of the shift. A program finds the points nearest to a location and calculates the exact correction between them. Files with this structure are used by national mapping agencies and surveyors, and they are particularly valuable for cadastral and engineering work, where small errors matter.

What are PNG files?

The PNG (Portable Network Graphics) file format was designed in the mid-1990s as an improved alternative to the previously existing JPG and GIF formats, and as an extension which would be particularly web-friendly. In time, PNG files have gained a wide popularity and are highly appreciated at the moment for their ability to provide a lossless compression of images, which translates in high-quality and detailed renderings.
