- Description
- The National Oceanic and Atmospheric Administration (NOAA), National Environmental Satellite, Data and Information Service (NESDIS), National Geophysical Data Center (NGDC) proposes to make an award to a contractor for research tasks and software development related to the Defense Meteorological Satellite Program (DMSP) Operational Linescan System (OLS) film scans and digital data. This project will develop the capability to bring the scanned DMSP-OLS film data into the current digital data processing stream, and will develop additional software to support the generation of nighttime lights data products. Development on this project will include: (1) An automated capability to convert scanned film data into a file format consistent with the OLS Interleaved Smooth (OIS) format; (2) An assessment of the accuracy of the nadir pixel geolocation of the above method; (3) Software that labels each pixel of OIS visible data as glare, sunlit, or marginal (poleward of glare and east of the terminator); (4) additional software development as needed. Items 1 and 2 contain a strong research component, and an initial experimental/protoyping phase is expected. Objective: To develop a capacity to convert Defense Meteorological Satellite Program (DMSP) Operational Linescan System (OLS) film scan images to a format consistent with the OLS Interleaved Smooth (OIS) format of the DMSP-OLS digital data in preparation for geolocation and regridding to assess the accuracy of the correlation between ephemeris and scanned imagery and to develop, test and deliver software for processing of DMSP nighttime lights data. Background: This statement of work consists of two separate but related activities. First, the conversion of film scans into a format similar to the OIS format is in part a research activity that will culminate in the delivery of a software package. LASON, Inc. is currently scanning portions of the DMSP-OLS film archive. The newly scanned TIFs will be converted to a compressed image format for storage. Previously scanned film has been stored in MrSID compressed format. These will be converted to the new image format as well. This contract covers the conversion of the image format into an OIS-like format. The OIS format is defined, and consists of interleaved visible and thermal band data, as well as metadata, including ephemeris information for the nadir pixel of each scan line. We will provide the contractor with compressed images as well as Two-Card Element sets (TCEs) for generation of ephemeris. The scanned film contains marginal fiducial marks and time stamps that we expect will be used to match ephemeris with the film data. The contractor is responsible for assessing the accuracy of the correlation between pixel location and ephemeris. NGDC will provide a Project Plan to the contractor to specify further the deliverables of the tasks. The second activity consists of the development and testing of software to support the processing of DMSP-OLS nighttime lights data. The contractor will be expected to work within the processing stream that currently exists at NGDC. A software system for a Linux platform should be delivered for the first activity. For the second activity, software should be written in IDL on a Linux platform. Tasks: Section A: Conversion of scanned film to OIS-like format. Task 1: Gather documentation on DMSP film creation and format. If documentation on certain aspects of the film does not exists, document what can be deduced from examination of the film. This is a research task. Deliverable: Summary Report, found documentation. Task 2: Ensure NGDC's close involvement with the project. This includes activities such as creating infrastructure for project visibility, documentation, such as an architecture document and a design document, and various analysis reports. These will be generated and shared during the appropriate parts of the development process. The contractor will also participate in reviews as necessary, including but not limited to Imaging Tool analysis, Architecture and Detailed Design. Deliverable: Documentation. Task 3: Generate ephemeris from TCEs. The TCEs will be provided by NGDC. The ephemeris generation model will be chosen by agreement between NGDC and the contractor. The contractor will organize the output ephemeris into orbits, synchronizing with the orbit numbers appearing on the film labels. Deliverables: Ephemeris with Orbit Numbers. Task 4: Develop a method to correlate ephemeris to film data using fiducial marks and time stamps. This will involve identifying the OLS edges of scan, identifying the crosshairs on the fiducial marks, and OCR of the time stamp and printed annotation where applicable. We expect a significant portion of the hours for this task will be used to research image analysis and optical recognition methods for automated identification of fiducial marks and time stamps. This is a research task. Deliverable: Report. Task 5: Develop a capability to resample overscanned images when creating OIS-like format. This should be controlled by the user via a command line flag or property. Deliverable: Software feature. Task 6: Build a Linux software system that converts the film scan images to an OIS-like file format, preferably starting from compressed film scans. The system will have two modes of operation, interactive and fully automated. The interactive component is expected to take the form of a GUI-based tool that lets an analyst "help" the software to identify fiducial marks, time stamps, and edges of scan (see task 4). The nature or function of the interactive component may change at the agreement of NGDC and the contractors. The time-per-image required of an analyst for the interactive tool will be determined by agreement between NGDC and the contractor. The fully automated mode may have a different accuracy than the interactive mode. Deliverable: Software. Task 7: Perform an accuracy analysis on the software system developed in Task 6. If they differ, analyze the accuracy for both the interactive and fully automated modes of operation. Deliverable: Report. Section B: Software to support processing of digital nighttime lights data. Task 8: Modify existing software, or add software to the existing processing stream, to flag each OIS pixel for quality of its nighttime lights data. The flags will be: good (no flag), sunlit, glare or marginal. Identify "glare" using existing algorithm provided by NGDC. Identify "sunlit" using terminator information from OIS header or scan line headers. Identify "marginal" as data poleward of glare and east of the terminator. Deliverable: Software. Task 9: Additional software development as needed. Deliverable: Software. Vendors should submit information and references supporting the following evaluation criteria: 1. Years of experience in developing software for processing DMSP data (15 pts). 2. Level of experience in software development for Linux platform (10 pts). 3. Degree of familiarity with OIS file format and semantics, including XDR/RPCGEN (30 pts). 4. Capability to generate ephemeris for DMSP satellites (20 pts). 5. Level of experience in optical recognition of image features and annotations (20 pts). 6. Level of familiarity with the DMSP-OLS scan geometry and other physical properties (20 pts.). It is not the intent of the Government to issue a separate solicitation for this requirement. Interested sources must submit a written qualifications statement by fax, clearly establishing capability to meet the above requirements. Faxed quotes are acceptable and should be sent to 303-497-3163. Quotes are required by December 16, 2002. All questions should be submitted in writing either by fax or email. This announcement/solicitation is being issued in accordance with Simplified Acquisition Procedures, FAR Part 13 (not to exceed $100,000). The award will be made as a firm fixed priced purchase order. FAR Clauses in full text are at http://www.ARNET.gov/far/. Agency level protest procedures can be found at http://oamweb.osec.doc.gov/conops/#REFERENCE . Incremental billing is acceptable.
