PurVIEW

To quickly transform the ArcGIS Desktop into a precise stereo-viewing environment enabling 3D visualization and data capture, ESRI Canada now offers the powerful and unique PurVIEW ArcGIS Desktop extension, developed by I.S.M. International Systemap Corp.

Data quality is central to any GIS implementation, and positional accuracy of features, efficient data capture, and viewing ease are paramount for an effective and reliable GIS.  The ability to view 3D stereoscopic data using PurVIEW provides a source for new datasets and a valuable resource that quickly reveals data inaccuracies and feature omissions.

PurVIEW interacts directly with the geodatabase, digital elevation models, and georeferenced imagery data, eliminating the need for an external imaging engine or photogrammetric interface.  Accurate data verification, direct editing, and enhanced feature digitizing are made possible with 3D data viewed stereoscopically, providing a rich environment for a variety of thematic applications from environmental assessments, to site/facility management, to earth sciences.

With PurVIEW, you can 

  • Access your data with Dynamic 3D Visualization 
    One mouse click converts legacy 2D data models into 3D, necessary for coherent viewing when superimposed on stereoscopic image models.

  • Extract 3D positional attribute information
    Cursor coordinate data stream enables positional attribute extraction such as slope, azimuth, aspect, height and other stored attribute features.

  • Digitize 3D features
    Enhanced digitizing tools and a 3D input device interface simplify new data capture.  To improve mapping productivity, smooth image roaming dynamically pans the underlying image for convenient inspections of large feature areas before digitizing.

  • Edit 3D data through direct geodatabase interaction
    Topologically defined 3D data can be directly accessed and edited, creating real time data, thereby eliminating conversion costs, CAD interoperability issues and transfer errors.

Why Use PurVIEW?

PurVIEW provides users with a refined positionally accurate three dimensional view of target locations. It is a valuable tool that can quickly reveal data omissions, errors or changes. Additionally, PurVIEW allows users to efficiently capture three dimensional data through specially designed input tools and through geodatabase direct editing.

Who Uses PurVIEW?

PurVIEW is useful for anyone implementing a positional, feature based GIS project or thematic application.  From municipal government transportation and transmission corridor management, to natural resource inventories and environmental assessments, PurVIEW is a valued tool for data quality assurance and precise feature editing. Some industry specific examples illustrating the value of PurVIEW are cited below:

Forestry - Older inventory mapping superimposed on steroscopic imagery serves as a "training set" for new polygon interpretations. Standard parameters from tree height to crown closure to site conditions can now be accurately measured, rather than estimated.

Environmental Assessment - Multi-discipline initiatives, now common or mandatory in corridor engineering - from pipeline to railroad, can also quickly embrace PurVIEW as an expedient geodatabase direct environment for diverse data model contributions.

Geology - Extracting location coordinates from image models for field sample collection not only improves efficiency but also ensures positive correlations with observable image characteristics. Observable features such as strike and dip can be directly delineated with slope, elevation and size established. Formation heights or strata thickness can also be measured and GPS geo-referenced seismic, aero-magnetic, geochemistry and other field data can be plotted accurately.

Site/Facility Management - Activities ranging from defence intelligence to urban engineering, field deployment layouts, mission logistics, support assessments, and
object/interpretation digitizing; can take advantage of stereoscopic visualization, a concept and environment similar to virtual reality.
