STEREO VIEWING
New technology will greatly influence what a client may want and IMT has revolutionized the manner in which map data is delivered to the client community. An example of this is apparent within British Columbia's forestry industry, where the emergence and later dominance of mono-restitution for line transfer, and the current demand for digital orthophoto, were both primarily caused by IMT.
We understand that clients depend on mapping companies to provide accurate, precise data. Thanks in part to IMT's philosophy of delivering more than just map data, and the emergence of the DiAP Viewer and PurVIEW, clients can now be certain that the data they receive is correct and complete.
Stereo viewing is as easy as point and click. The cursor automatically follows the terrain surface, enabling end users to interpret and digitize 3D features directly into their maps.
Rather than estimate with a variety of primitive devices such as parallax wedges and stereometer bars, these systems enable you to accurately determine the following with a simple click of the mouse:
- Tree height measurement;
- Crown closure determination;
- Slope;
- Elevation and
- Aspect
Direct feature digitizing eliminates the entire polygon transferring process and its inevitable errors. Furthermore, digitized features conform precisely to the terrain surface compatible with your GIS data or, in the case of PurVIEW – directly into your geo-database.
PurVIEW
Introduced to the GIS and ESRI world in 2005, PurVIEW is a product of I.S.M. International SysteMap Corp. They are the original developer of the Digital image Analytical Photogrammetry (DiAP) workstation and DiAP Viewer, which are now mapping industry standards. Distilled from decades-long, in-depth experience, and due in large part to an outcry from the GIS community, PurVIEW encapsulates the net benefits for ArcGIS™ desktops.
PurView operates in much the same way as DiAP Viewer. While DiAP Viewer is a MicroStation based 3D stereo viewing system for the end user’s desktop, PurView runs as an add-on to ESRI's Arc Map platform and offers GIS direct digitizing with the "Z" coordinate retained.
DiAP Viewer
IMT first introduced the ISM DiAP Viewer in 1996 and was the exclusive distributor of this technology in British Columbia. DiAP Viewer was the world’s first affordable digital stereo viewing system, and drove the next great leap forward in client empowerment. While no longer supported or sold, DiAP Viewer is still used in sectors requiring the interpretation of imagery as a source of information, from provincial government agencies to environmental and forestry consultants.
The BC Ministry of Forests quickly realized DiAP Viewer’s potential and purchased over 40 systems for each District and Regional Ministry of Forests office in the province. The entire forestry inventory exercise, from interpretation to feature digitizing and final mapping, was then able be performed by a forestor all within a single environment.
The Ministry of Forests has followed the evolution of DiAP Viewer and has begun purchasing PurVIEW systems.
Testimonials
Good news should be shared. Read what our clients have to say:
"The DiAP Viewer has proven to me to be an indispensable tool. I can also see that it could be a good, cost-effective tool for more intense map updating."
