 ERDAS IMAGINE

Change Detection 

Change detection is used to highlight or identify significant differences in imagery acquired at different times; playing an important role in the lifecycle of GIS features and providing the capability to update feature data based on new imagery. 

National Mapping Agencies - Africa

South Africa’s National Mapping Organisation, the Chief Directorate: National Geo-spatial Information (CD: NGI) relies on Hexagon Geospatial for their geospatial project needs because many areas of Africa are either unmapped or covered by outdated maps in need of updating. 

 

Creating Customised Spatial Models with Point Clouds

Using spatial modeler operators to process point clouds in ERDAS IMAGINE 2014, using powerful new tools which allow editing, classification, filtering and surfacing of point cloud data.

Hexagon Geospatial Solutions for Distributed Common Ground Station (DCGS)

With a complete, geospatially-enabled, service oriented architecture, Intergraph brings the tactical community, through the Distributed Common Ground Station (DCGS) programme - a host of next generation solutions that promise to increase situational awareness, ensure accuracy and reduce mission latency.

 

Discriminant Function Change in ERDAS IMAGINE

Intergraph developed an algorithm for change detection between two co-registered images acquired at different dates. This algorithm characterises the natural distribution of spectral clusters in the data space of one image, then uses a discriminant function to measure probability of change of the pixels in the other image.

 

Volumetric Measure Using Geospatial Technology

Using high-resolution terrain information generated from stereo imagery, users can obtain volumetric measurements for monitoring and surface analysis. This whitepaper details workflows that could be used for such a task - preparing the project and stereo imagery, creating a digital surface model and taking volumetric measurements.

 

3D Geoinformation from Satellite Sensors

Realistic 3D vector data, Building Information Modeling (BIM), 3D terrain and imagery are all important components of building a GIS infrastructure that goes beyond two dimensions. The convergence of GIS, photogrammetry and remote sensing data, tools and methods allows making integrated 3D GIS applications a reality.

 

 

ERDAS Engine - A Simple and Cost-Effective Way to Increase Processing Capacity

A simple and cost-effective way to increase processing capacity, ERDAS Engine is designed to complement the current ERDAS desktop products by enabling them to run more processes simultaneously.

ERDAS APOLLO

ERDAS APOLLO 2014 Vector Data Management

Hexagon products have provided a strategy for cataloguing, managing and delivering geospatial data over the web, but there has been a gap with vector data. ERDAS APOLLO can be used for complete Vector Data Management to crawl vector data stores and share data across different applications using OGC WMS, WFS and WFST services and download capabilities.

Image Exploitation for the Enterprise

Growing standards, increased bandwidth, service oriented architecture and affordable multiprocessing are changing the way that we work. Collaborative capabilities enable users to consume and share geospatial data and services with the producers of GIS data improving the decision making process.

Easily Unlocking and Utilising Geodatabases

Seamlessly work with Esri data in their workflows, with three Esri® Geodatabases – Personal geodatabase (single users working with small datasets), file geodatabase (can scale to very large file sizes, useful for data exchange) and ArcSDE geodatabases (support a multiuser editing environment, can manage large datasets).

 

GeoMedia Architecture

Geographic Information Systems (GIS) are mainly about data. Big data. GIS data needs to be independent of the software that created it in order to allow the free flow of data through and between organisations. GeoMedia software, since its inception, has been based on open-architecture, deploys open standards and is data independent.

 

Leveraging your GIS Data within an Integrated 3D Environment

With 3D becoming a commonly used method of geospatial processing, there is a growing need for a system that unites a corporation’s GIS data and 3D visualisation. Specifically, a system is needed that someone with little to no training can use to connect to a wide variety of GIS databases and rapidly visualise and interact with them in a 3D environment.

Providing Government Collaboration and Public Distribution with Spatial Data Infrastructures

GIS and interoperability technologies enable the deployment of spatial data infrastructures (SDIs) for collaboration and distribution of geospatial data. This integrated framework of geospatial data, metadata and tools allows government agencies around the world to use and share geospatial data in an efficient and flexible way.

 Mobile Map Works

Henry County Mobile Field Workflows 2014

For years organisations relied on desktop GIS, requiring skilled technical staff and expensive overheads. Today, mobile and tablet devices have the processing power, storage and network capabilities to support high end applications, including powerful data access, superior visualisation, creation, query and analysis.

Analysing the ECW Format Lifecycle

This whitepaper addresses customer questions on Enhanced Compressed Wavelet (ECW) image compression technology. Grouped into four key image format characteristics – compression (encoding) speed, image quality, file size and decompression (decoding) speed – it is critical to understand how each characteristic impacts the others.
