摘要：The use of digital imagery is ever increasing for resource applications due to enabling technology to integrate digital imagery with other land related digital data in a digital mapping environment or in a Geographic Information System (GIS). To support increasing demand for digital imagery, the Base Mapping and Geomatic Services Branch (BMGS) of the British Columbia Ministry of Sustainable Resource Management (MSRM), Canada initiated the Digital Image Management (DIM) program. The purpose of this program is to establish and maintain a semi-automated interoperable computer-based system to support the acquisition, management, discovery and web-based distribution of geographic digital imagery for the province of British Columbia, Canada. DIM will address the data management issues related to the capture and operations of a very large volume of geo-referenced raster based imagery and digital mapping products including but not limited to scanned aerial photos, orthophotos, satellite imagery, canned stereo models and DEM. DIM will establish a corporate, universal data access facility, commonly known as the "image discovery system", allowing all BC Government offices in Victoria, Regions and public users across Canada to access the orthophotos and land related digital products through Internet. The DIM design objective is to operate on the Internet using standard browser technology, is interoperable, utilizes standard computing hardware, is extensible, distributed, open and OGC and ISO compliant. The system provides access to the BC Government geo-referenced digital image data holdings from air-borne to space-borne data. All software components of DIM is Open GIS Consortium (OGC) compliant and in compliant with Land Resource Data Warehouse (LRDW) of MSRM. DIM will provide capability to download lossy compressed and or lossless data in a reasonable time without special software. The scope of this paper is to describe the system requirements and architecture for DIM. It will describe the process to evaluate a number of Standard Commercial Off-the-Shelf (SCOT) software components for both DIM system requirements and OGC/ISO compliance. The approach and technology used in this evaluation will be discussed in the paper. The study will concentrate on an interoperable and operational system to provide Internet access for digital images in British Columbia, Canada
