New Linear Optimization Technology to compress spatial data files

New Linear Optimization Technology to compress spatial data files


British Columbia, Canada, 04 June 2007: Safe Software is developing an application in association with TCI which will integrate Safe Software’s FME with Curvefitter linear optimization technology.

The new FME 2007 will provide users with the capability to create smooth linework from point to point linework while reducing file size by up to 80 percent. File size reductions of this magnitude will result in faster processing times for CAD and GIS data, and fewer processing problems caused by limited available memory. By inserting arcs into linework that depicts map features, Curvefitter technology also allows FME users to create a better representation of real world entities.

FME’s data manipulation capability allows Curvefitter technology to be extended beyond simple linework to process complex linework with shared boundaries. FME can automatically determine which linework segments are used by multiple boundaries, curvefit those segments separately, and then reassemble the boundaries using the same curvefitted segment. Complex linework with topology such as parcels, or natural features such as vegetation and soil types, can now be optimized maintaining topological integrity.

Curvefitter creates smaller file sizes by reducing the amount of data required to represent smooth linework. Guided by a fuzzy logic processor, Curvefitter replaces a series of line segments with a combination of lines and arc segments to create smooth curving lines.

About Safe Software and FME:
Safe Software is the maker of FME, a spatial ETL (Extract, Transform and Load) technology that enables translation, transformation, and web-based distribution of geospatial data in GIS, CAD, raster and database formats. FME is widely being used by government, the utilities sector, and resource industries including mining, oil and gas, and forestry. FME manages database loading, data extraction from legacy systems, merging multiple data sources, coordinate system conversion, and format to format translation for the exchange of map data.
