Technical note

Before you convert SDAT to IGES

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. IGES 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. SDAT is made of pixels and IGES 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 an IGES 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 SDAT to begin with.

Map Data Workflow

From map data to a working drawing

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

SDAT to IGES Conversion

What are SDAT files?

SDAT is the data file of the SAGA GIS grid format. SAGA (System for Automated Geoscientific Analyses) is a free, open-source GIS widely used for terrain analysis, hydrology, soil science, climate studies, and other geoscientific work. A grid in this format is a map made of equal square cells, such as an elevation model, with one value in each cell. The .sdat file holds only these values in binary form, while a small text file with the same name and the .sgrd extension describes them: the size of the grid, its position, the cell size, the type of numbers, and the value that marks missing data. A history file with the .hgrd extension and a projection file with the .prj extension may accompany them. SAGA can also pack all of these files into one archive.

What are IGES files?

IGES (Initial Graphics Exchange Specification) is a widely used file format for exchanging 2D and 3D CAD data between different design and engineering software. It supports wireframe, surface, and solid models, making it a common standard in mechanical, aerospace, and automotive industries.
