Technical note

KAP to IGS: 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. IGS 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. A line in a KAP image is several pixels wide, so tracing it can mean different things and the mode is yours to choose. Centreline returns a single line running down the middle of each stroke, which is what a scanned drawing needs: one entity per line, snappable and dimensionable, rather than a long thin rectangle around it. Outline follows both edges and returns closed shapes, which suits clipart, logos and anything that will be filled or cut. A precision setting controls how closely the traced paths follow the pixel edges. One thing to plan for: vectorised output from this path is black and white, so colour in the KAP does not survive as colour in the IGS.

Map Data Workflow

From map data to a working drawing

Site plans, utility routes and parcel boundaries often start out as KAP and end up in IGS. 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 IGS 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.

Security was our top concern when evaluating file conversion tools. reaConverter’s offline mode and role-based access controls let us lock it down for sensitive environments. No unexpected network calls or bloat — just clean, fast conversions. Even passed our pen-testing scans without a hitch.

FAQ

KAP to IGS Conversion

What are KAP files?

KAP is the file extension of the BSB raster nautical chart format, created by BSB Electronic Charts and later developed by Maptech. A file of this type holds a scanned paper sea chart as a picture, together with the information needed to place it on the globe, which lets navigation software show the ship's position on the chart. The format became the usual way of distributing official raster charts in several countries, including those of the U.S. National Oceanic and Atmospheric Administration (NOAA). A large chart is often split into several panels, one file per panel, and a small .bsb text file may tie them together. Chart plotters, open-source navigation programs, and mapping software can read these files, and they are also used in geographic information systems.

What are IGS files?

The IGS (Initial Graphics Exchange Specification) file format is a standardized CAD data exchange format used to transfer 2D and 3D model data between different CAD systems. Developed in the 1980s, IGES ensures compatibility across various engineering and design software by storing geometric data, annotations, and structure in a neutral ASCII or binary format.
