VAccess Information Technology Infrastructure
Project Leader: Dr. Ruixin Yang, (L) GMUSince the start of the project, the IT group has been working on building and enhancing the IT infrastructure, in particular, at CEOSR, the primary contractor. In the first half-year, we set up the IT infrastructure including the hardware and software listed for the first two quarters. The infrastructure is the major facility to support activities in this project at GMU and with the Team. By the end of the first year, we will accomplish the other items including setting up web-based online systems for data and metadata access and the AVHRR antenna download station. See Figure 17 for the GMU library roof top installation of the L-Band feed and down converter and figure 18 for the Command and Control Center Console.
This year, the IT group will continue its support of the IT infrastructure for this project. The major tasks include hardware and software maintenance, new hardware/software purchases/upgrades, online system operations, data populations, enabling collaboration, IT training, etc. We will continue to leverage the systems we developed for other projects at CEOSR and our expertise to manage and distribute data associated with this project. An FTP site has been established for Team VAccess to access project documents and use of TRMM and shortly MODIS value-added data products. We will continue to train students on software applications, data information system development and maintenance as well as application research such as data mining.

Data requirements will be established after an assessment of what NASA and NOAA sources can provide at minimum cost, e.g. via RSIP, with sources currently in use by the Commonwealth, (SPOT and Digital Ortho Quarter Quad), with recommended commercial and alternate sources available and recommended by VAccess – MAGIC after discussions with the TAC about emphasis areas and priorities. The list of high resolution data sets identified will be submitted to Stennis for information purposes. VAccess – MAGIC will initiate procurement of what is needed, joining forces to gain price advantages where practical.
The proposed equipment application and software to be purchased for year two is listed in II.Facilities and Equipment section.
Milestones
• Complete an Antenna system test and metadata population for this project at GMU.
o Make the Antenna system ready for operation and for student training.
o Integrate RS data from the antenna and other IT components.Special Equipment
Hand-held hyperspectral instrument measurements (see figures 19 (a) and (b) ), will be made under laboratory as well as field conditions in support of several VAccess – MAGIC activities, e.g. ‘Remote Sensing of Plant Canopies’.
