Technical note

How ILI and PNG differ in practice

An ILI file holds geometry and an attribute table, and nothing at all about appearance. Colours, line weights, fills and labels are properties of the GIS project rather than of the file, which is why the same ILI looks different in every program that opens it. The PNG render therefore falls back on defaults and will not match the styled map you see in QGIS or ArcGIS. Expect a clean drawing of the geometry rather than a finished cartographic product. ILI coordinates are positions on the earth, tied to a stated reference system, and each feature carries its own row of attributes. PNG is a picture: the coordinates become pixel positions and the attribute table is dropped entirely. That is fine for illustration and no use as data, so keep the ILI original if anything downstream needs to query or reproject the features.

Map Data Workflow

Turn GIS data into something anyone can open

A map saved as PNG opens on any computer and any phone. reaConverter produces those from ILI in batch, entirely offline.

  • 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 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.

FAQ

ILI to PNG Conversion

What are ILI files?

ILI is the model file of INTERLIS, the Swiss standard for describing and exchanging geographic data. Before data are passed from one office or program to another, the agreement on what exactly the data contain is written in a file of this type: which kinds of objects exist, such as parcels, buildings, and roads, which attributes each has, how they are related, and which rules the values must obey. The data themselves are not stored here but in separate transfer files, so that one model can serve many deliveries. INTERLIS was created in Switzerland in the 1990s for cadastral surveying and is now mandatory for official Swiss geodata, and it is also used in other countries. There are two versions, INTERLIS 1 and INTERLIS 2, and both use the .ili extension for models.

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.
