GeoVisu Suite is a dedicated georeferenced data viewer and GPS utility tool designed to consolidate spatial data, imagery, and real-time tracking into a single, localized workstation.
The application streamlines visual analytics by automatically aligning disjointed spatial files—such as satellite imagery, vector maps, and active GPS tracking—into a unified, layered interface. It operates heavily on the principles of geovisualization, prioritizing human data exploration over raw data storage. Core Components and Capabilities
The suite operates as an integrated package consisting of specialized mini-utilities that manage distinct stages of the geospatial pipeline:
GeoVisu: The primary viewing console that manages layer overlays and handles real-time navigation.
GpsDiffuser: A background utility that splits data streams. It allows you to run GeoVisu for visualization on one end while actively receiving raw GPS sentences on another.
GVConverter: A file-conversion engine that transforms custom .GVN log histories into standard, universally readable raw NMEA data strings. Key Analytical Features
“Moving Map” Navigation: Supports interactive, real-time spatial positioning by overlaying live coordinates onto historical maps. It is compatible with standard NMEA 0183 protocols and USB-connected Garmin devices.
Automated Layer Management: Instead of forcing manual calibration, the suite automatically reads geodetic projections. It stacks raster and satellite imagery sequentially, positioning the highest-resolution layers on top by default.
Heterogeneous Data Aggregation: Streamlines analysis by allowing cross-format visualization. Users can combine vector layers with raster backdrops simultaneously.
Direct Archive Reading: To optimize performance speeds, the application natively unpacks and reads compressed .ZIP and .GZ (Gzip) folders on the fly without a separate extraction process. Supported Formats & Protocols
The software’s analytical capacity stems from its ability to ingest varied geographic formats directly: Supported Formats Raster / Imagery
GeoTIFF, ECW & ECWP, MrSID, OziExplorer Maps, BSB Raster Charts Vector / Graphics
ESRI Shapefiles (.SHP), MapInfo (.MIF), Google Earth (.KML/.KMZ), OpenStreetMap (.OSM) GPS Track Logs
GPX, NMEA logs, Garmin XML, Magellan logs, Lowrance USR, Wintec Web Streams Direct network loading via HTTP or ECWP protocols Technical Specifications & Architecture
Deployment Options: Distributed via a standard installer or as a fully portable standalone folder. The portable version requires no system registry changes and can be run straight from a USB drive.
Embedded Data Mode: Features a specialized “embedded mode” that restricts the software from caching or writing temporary tracking files to the host hard drive, optimizing execution speed.
Licensing: Available free of charge for individual use, though it is proprietary and not open-source.
Platform Compatibility: Designed natively for legacy and modern Windows environments (from Windows 2000 through modern iterations). Cross-platform deployments (Mac/Linux) are typically supported via third-party repositories.
