Technical note

Before you convert GFF to PLT

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. PLT 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. GFF is made of pixels and PLT 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 PLT 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 GFF to begin with.

Map Data Workflow

From map data to a working drawing

Site plans, utility routes and parcel boundaries often start out as GFF and end up in PLT. reaConverter turns the layers into drawing entities in batch, so a full project folder moves across in one run.

  • Convert every layer in a folder to PLT 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.

FAQ

GFF to PLT Conversion

What are GFF files?

GFF (GSAT File Format) is a raster image format developed by Sandia National Laboratories in the United States to store images and image products from its synthetic aperture radar (SAR) systems. The name comes from the Ground-based SAR Applications Testbed (GSAT), the program in which the format was created. A file of this type consists of a header of variable length, which records the configuration and performance parameters of the instrument and the image, followed by a matrix of pixel data. The format was designed to allow custom annotation of radar images, and it has gone through several revisions as Sandia's radar programs developed. It remains the main image format of the laboratory, which keeps a large library of SAR images in this form.

What are PLT files?

PLT is a vector image format representing the HPGL standard language developed by Hewlett-Packard for printing line drawings. HPGL is supported by AutoCAD and other CAD software programs. PLT files represent plotter images that can be printed using a computer printer specialized in vector graphics (called "plotter"), which renders images as lines not as dots.

Can reaConverter convert GFF to PLT?

Yes! reaConverter instantly converts .gff to .plt 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 GFF to PLT it replaces the usual detour through QGIS, ArcGIS or ogr2ogr: add the files, pick the output format, and the whole batch converts offline. Surveyors, planners and engineering teams use it to pass data between GIS, CAD and everyday document formats.

Why choose offline conversion with reaConverter?
