Terrain Technologies & Skyline Software Systems

Terrain Technologies is Skyline Software Systems' distributor in Spain, the Czech Republic and Ecuador. Skyline is a leading provider of 3D earth visualization software and services. The company offers a comprehensive platform of applications, tools and services that enable the creation and dissemination of interactive, photo-realistic 3D environments. Skyline has built a “best of breed” set of tools that remain focused on the needs of our customers including flexibility, efficiency and robustness..



The TerraBuilder family of tools generates terrain and urban model databases from a wide variety of data types.


Random Name

TerrainBuilder merges aerial photos, satellite images, and digital elevation models of different sizes and resolutions into a photo-realistic, geographically accurate terrain database.


Random Name

PhotoMesh merges 3D mesh models together with classification layers, and other model layers into a multi-resolution and stream-optimized 3D Mesh Layer database (3DML).


Random Name

Fully automates the generation of high-resolution, textured, 3D mesh models from standard 2D photographs, offering a significant reduction in cost and time compared to traditional modeling methods.



TerraExplorer for Desktop

Cutting-edge 3D GIS desktop viewer and creator for viewing, querying, analyzing, and presenting geospatial data in a high resolution 3D environment, as well as creating and publishing realistic 3D views.


TerraExplorer for Mobile

Advanced 3D GIS viewer and editor for Android and iOS mobile devices with professional-grade tools for viewing, querying, analyzing and editing massive online or offline datasets in a high resolution 3D environment.


TerraExplorer for Web

Powerful web-based 3D GIS viewer and editor with advanced capabilities for viewing, analyzing, presenting, and creating 3D views in a high resolution 3D environment.


TerraGate supports the client-server data delivery requirements of Skyline's 3D visualization applications, enabling massive amounts of data to be efficiently streamed to thousands of concurrent users through a suite of services including: Terrain Service, Web Feature Service and 3D Mesh Layer Service.

Terrain Service

Random Name

The TerraGate Terrain Service is a powerful network data server technology designed to stream 3D geographic data in real-time. The Terrain Service client-server model is optimized to handle thousands of concurrent users accessing virtually unlimited sized databases in low-bandwidth situations.

Web Feature Service

Random Name

WFS serves feature layers of polylines, polygons and points to all TEP and OGC WFS client applications. It also supports advanced spatial and attribute queries from TerraExplorer and other WFS clients. It has several sub-systems that are individually responsible for handling streaming requests from several different sources.

3D Mesh Layer Service

Random Name

Powerful 3D city model service technology for sharing and managing 3D Mesh Layer (3DML) databases created from PhotoMesh city models together with classification layers, individually modeled layers, and BIM datasets. Streams fully textured and geospatially-enabled 3D city models to thousands of TerraExplorer mobile/desktop clients.
