Despite the challenging economy, a record crowd of more than 1,500 people attended the American Society for Photogrammetry and Remote Sensing (ASPRS) 2009 Annual Conference March 9-13 at the Marriott Waterfront Hotel in Baltimore. The conference marked the 75th anniversary for the society and carried the theme “Reflection of the Past – Vision of the Future.”
According to Dr. Bradley D. Doorn, the society’s new president, the conference location contributed to the increased number of visitors, but individuals and corporations are also seeking a greater understanding of how to apply remote sensing and photogrammetry technologies in a practical and cost-effective way. “People are seeing that they can now use this technology and data for all sorts of applications,” Doorn says. “It isn’t just specialized for certain segments of the government or profession; it’s getting pervasive use in the public. And that’s a challenge for us as professionals-we have to figure out what our role is in making sure that we’re at the forefront and relevant to these applications.”
Doorn addressed attendees during the General Session on March 12 with a presentation titled “Mapping, Monitoring and Preparing for Change,” in which he discussed the ability of photogrammetry and remote sensing technologies to meet the needs of a changing world. It’s a theme that ASPRS understands well but hasn’t always communicated clearly. In the past, the society’s membership and conferences were dominated by researchers and scientists. However, all that is changing as more businesses embrace the practical aspects of the technologies. “ASPRS is about the relevance of the science, not just the science itself,” Doorn says. “Today, we have a full spectrum of members, from students to academics to the government and business side, and we’re striving to link these areas together.”
Education and Outreach
According to Doorn, ASPRS has always sought to engage its members. Recently, however, the society has begun placing more of an emphasis on engaging students. “We’ve heard from academics and business professionals about the need in the U.S. for an educated and high-tech workforce that’s active in the geospatial arena-specifically with regard to imagery,” Doorn says. “So we’ve started this year to put a lot more emphasis on student activities.”
The society is also actively involved in supporting both its individual and corporate members through the current economic challenges by allowing laid-off members to keep their member privileges even if they can’t pay their dues and by ensuring that the society’s certification program has real employment value. “We want to enable our members to get the skills they need for a better job, maybe internships, experience, education,” Doorn says. “We have an ad hoc committee that is putting together a plan that addresses what we can do as a society to assist our individual members with networking and job searches and to assist the sustaining members that are posting jobs and searching for new workers.” Doorn notes that the society’s regional groups and conferences continue to play a key role in networking and membership involvement.
On a broader scale, the society is pursuing strategies that will help its members communicate the importance of remote sensing technologies and technical expertise in fields such as climate change, biofuels and food security. ASPRS advisory groups work closely with the federal government on policy issues related to geospatial activities to help ensure that informed decisions are made, and it encourages its members to get involved in the dialogue. “I think we can still do a lot to answer the questions, ‘Where do the remote sensing skills and data fit into this new dynamic geospatial era’ and ‘Where do we look for the expertise that we need?’” Doorn says. “We know [remote sensing] is relevant and extremely important. But how are businesses going to manage it? How’s the government going to support it? These are some of the issues we’re still monitoring, and the dialogue will be continuous.”
A Changing Future
The changes that are occurring in the use of remote sensing technologies and photogrammetry are reflected in ASPRS’s membership. While Doorn says that membership numbers have remained steady-no small feat in the current economic climate-the types of firms that are involved in the organization have changed as firms seek to become more diversified. For example, the society has seen increased involvement from GIS professionals who are interested in understanding how to collect data from imagery and from surveyors who have moved into photogrammetry. The society’s traditional members are evolving, as well, as they embrace new technologies and applications.
Through its connections to the private sector, academia and government agencies, ASPRS seeks to bridge the gaps and pave the way to a successful future for its members.
“Our heritage is remote sensing and photogrammetry,” Doorn says. “We want to continue that, but we want to recognize that in this new world that we’re in, these technologies and capabilities are evolving. We want to make sure that our members are getting the services they need and getting their needs met in this new environment.”

ITT VISUAL INFORMATION SOLUTIONS, a wholly owned subsidiary of ITT Corp., released ENVI 4.6 software for processing and analyzing geospatial imagery. The newest ENVI release builds on workflow advances introduced in earlier versions by delivering automated processes and procedures that walk users through previously complex image processing and analysis tasks. ENVI 4.6 also adds file format support for image data from the new GeoEye-1 and KOMPSAT-2 satellites. New tools include anomaly detection, a Google Earth bridge, image to map registration, terrain-based orthorectification, and enhanced change detection. In addition, ENVI 4.6 also introduces a new Target Detection Wizard for finding specific objects in large image scenes.
ITT also released the ENVI Orthorectification Module, a new add-on module to ENVI. The new module combines the advanced, rigorous model from renowned orthorectification experts, Spacemetric, with an ENVI-based automated workflow approach that steps users through the orthorectification process to geometrically correct an image to remove distortions that occur during image capture. Providing support for a wide set of both satellite and aerial sensors, the module makes the complex task of orthorectifying imagery accessible to image analysts of various experience levels while providing mathematically accurate results.
