ADVANCES IN CORE TECHNOLOGIES As stated in the introduction, the level of synergism created by enhanced, widely-affordable, computer capabilities and the integration of photogrammetry, remote sensing, GIS, GPS and related technologies has fostered an environment for new applications and expanding routine use of the technologies. Recent advances in photogrammetric appli- cations are primarily in the fields of softcopy photogram- metry and GPS photogrammetry. Over the last several years, softcopy photogrammetry has achieved operational status in numerous organizations, both private and governmental. Advances in several areas of hardware and software development have combined to produce commercial softcopy mapping systems that meet the needs of users with various accuracy and performance requirements, at varying cost levels. These advances in- clude: - Improved geometric and radiometric scanner resolu- tion and accuracy. - The availability of scanners of different optical and mechanical characteristics that cover a wide range of price/performance ratios. - Significant advances in softcopy photogrammetric workstation performance. This field has been one of the main beneficiaries of the incredible gains in raw workstation CPU performance and storage capacity seen everywhere in the computer industry. - Ongoing improvements in softcopy software, both in terms of user interface, as well as algorithmic capabili- ties. Of great interest for the future will be the increased use of direct digital imagery from a variety of sensors, including those on board the new very high resolution digital Earth orbiting satellites. In addition, research will focus on the area of image compression, storage, and distribution across the Internet. Interest will also focus on further develop- ments in the fields of feature extraction and object recogni- tion. The last five years have seen GPS photogrammetry evolve from a process requiring very specialized expertise and execution to a more robust and operational technology. Much of the operational improvement can be attributed to the cooperative relationship between the various user groups and vendor communities. What were major obstacles to implementation a few years ago have been simplified or eliminated through improvements in hardware, software, and system integration. The use of GPS in the aerial photogrammetric process, with the subsequent reduction or elimination of ground control, is now considered by many to be routine. Specific improvements include: International Archives of Photogrammetry and Remote Sensing. Vol. XXXI, Part B6. Vienna 1996 - Greatly enhanced GPS satellite coverage. - Higher performance and lower cost GPS receivers. - Widespread implementation of On-The-Fly integer resolution software, reducing the need for continuous lock during long flights. - Better integration between photogrammetric cameras and GPS receivers. - more robust enduser GPS processing software, with enhanced usability. - Improved bundle adjustment software that takes full advantage of GPS parameters. The scope of GPS photogrammetry has lately broadened to include the integration of sensors other than aerial cameras, and the integration of inertial navigation systems in addition to GPS. The scope of application is also no longer restricted to airborne platforms, as ground-based mobile mapping systems, which utilize some of the same principles as the airborne systems, become operational. There is every rea- son to expect that the application of GPS to all aspects of photogrammetry will continue to increase in the next five years. “Geographic information systems (GIS) allow decision- makers to analyze complex spatial inter-relationships be- tween variables that affect a particular problem. It is important to note such systems not only facilitate more timely, efficient, and cost-effective decision-making, they also foster better decision-making since they enable users to conduct unique, and otherwise often infeasible, analytic tasks.” These words written by James Merchant and Wil- liam Ripple in the forward of the first annual GIS edition of PE&RS in October of 1987 are even more appropriate today as the use of GIS continues to grow exponentially and the technology evolves to help us answer increasingly complex resource management questions. Developing and enhanc- ing interfaces with other technologies such as remote sens- ing and global positioning systems is also of primary impor- tance. Remote sensing and GPS technologies, while important in stand-alone applications, also have become critical data sources for new photogrammetric and GIS applications. Less costly, more portable, highly accurate and fully inte- grated GPS systems have become widely used and provide the accurate and precise locational information for photo- grammetric, remote sensing and GIS applications. The potential availability of a constellation of high resolution commercial satellites is an exciting and important advance- ment for the remote sensing community. The proposed capabilities of one meter plus resolution with some combi- nation of multispectral and/or panchromatic and/or stereo imagery advances these systems into new photogrammetric and GIS applications. These applications, coupled with the advances in GPS-linked aircraft platforms with digital cam- eras, scanners or video systems, presents a wide range of options for performing high resolution applications that had
