FugroViewer
FugroViewer is a robust, easy-to-use freeware designed to help users make the most of their geospatial data. We have developed it for use with various types of raster- and vector-based geospatial datasets, including data from photogrammetric, lidar, and IFSAR sources. FugroViewer 3.5 is available for download. FugroViewer now reads files up to six times larger, with improved graphics handling to decrease the rendering time of data and increase efficiency. FugroViewer supports the latest open file format for lidar data storage and delivery. Display elevation and terrain model data in standard ortho, 3D perspective, and cross-section/profile views. Display GPS time and RGB value, if the information is available. Color TINs by elevation using blue-to-red earth tone, or intensity values. Overlay imagery and vectors onto your 3D elevation and terrain datasets. Examine lidar point clouds by classification, flight line, return number, or source ID.

GRASS GIS
GRASS GIS (Geographic Resources Analysis Support System) is a free and open-source Geographic Information System (GIS) software suite utilized for geospatial data management and analysis, image processing, graphics and map production, spatial modeling, and visualization. It supports raster, vector, and geospatial processing, enabling advanced modeling, data management, imagery processing, and time series analysis with a Python API, optimized for large-scale analysis. GRASS GIS is compatible with multiple operating systems, including OS X, Windows, and Linux, and can be accessed through a graphical user interface or integrated with other software such as QGIS. The software includes over 350 modules for rendering maps and images, manipulating raster and vector data, processing multispectral image data, and creating, managing, and storing spatial data. GRASS GIS is widely used in academic and commercial settings, as well as by governmental agencies.

TopoShare
TopoShare is a geospatial data management platform developed by TopoDOT to optimize digital twin production processes at minimal costs. It enables efficient organization, storage, and access to extensive geospatial datasets, including point clouds, images, coordinates, and metadata. Integrated with TopoDOT, TopoShare facilitates the reorganization of large-area point cloud data into manageable tiles, creating a geospatial project data warehouse within cloud services like Amazon S3 or Azure. Users can access project data through an intuitive geospatial display, selecting and downloading desired datasets directly into TopoDOT for further analysis and application. TopoShare Enterprise extends these capabilities across operations, providing unlimited interaction with project data, metadata, quality assessments, and digital twins, all while maintaining low interaction costs. This approach supports an on-demand production process, delivering quality-controlled topographies, 3D models, etc.

QGIS
Create, edit, visualize, analyze and publish geospatial information on Windows, Mac, Linux, BSD and mobile devices. For your desktop, server, in your web browser and as developer libraries. QGIS is a user-friendly open-source Geographic Information System (GIS) licensed under the GNU General Public License. QGIS is an official project of the Open Source Geospatial Foundation (OSGeo). It runs on Linux, Unix, Mac OSX, Windows and Android and supports numerous vector, raster, and database formats and functionalities. QGIS provides a continously growing number of capabilities provided by core functions and plugins. You can visualize, manage, edit, analyze data, and compose printable maps. We also collect case studies of how people all over the world use QGIS for their GIS work. You can view combinations of vector and raster data (in 2D or 3D) in different formats and projections without conversion to an internal or common format.
