Current Spatial Data in House

Currently, we have about 100 GB of spatial and digital data in different format. In order to efficiently store this amount of data we use a Semantic DBMS system - Sem-ODB.





Ocean Surface Temperature
One year (1987) of weekly Ocean Temperature data was supplied by the University of Miami Rosenstiel School of Marine and Atmospheric Science.This represents 52 data files of 64800 bytes each. This is raw data, so the format of the files is binary. In order to get more detail about this data set, we have developed a client/server Java based interactive system on the web available for users to browse.

Ozone (TOMS, Total Ozone Mapping Spectrometer)
Ozone Data (deployed by NASA's Goddard Space Flight Center) has been collected for a period of up to 15 years (1978-1994) from two different satellites -- Meteor3 and Nimbus7 -- and two different frequencies -- monthly and daily. The monthly readings are obtained by taking the daily readings for the entire month and recording the mean value for each zone. These files are approximately 103680 bytes each and they are in binary format. The ozone web page can be visited to get more information about this data set. Some more recent data (1996 -1997) from the Earth Probe satellite is also available

SeaWiFS
Several megabytes of simulated SeaWiFS (Sea Viewing Wide Field-of-view Sensor) data (deployed by NASA), have been derived from one day's reading of the SeaStar satellite using eight different sensors to capture global ocean color. Also, some new SeaWiFS data sets which consists of satellite measurements of global and regional ocean color data have been obtained by the Sea-viewing Wide Field-of-view Sensor in orbit on the OrbView-2 (formerly SeaStar) platform. This new SeaWiFS was launched August 1, 1997 by a Pegasus XL launch vehicle.

  • We currently have about 60Gb of SeaWiFS data.
  • Landsat
    The Landsat (Thematic Mapper and MSS) data (deployed by NASA) at the center is of two types -- Quads and Scenes -- with images from several parts of the world. Each Quad image is about 13 MB and each Scene image is about 37 MB. To get more information about this data our Landsat web page can be browsed

  • We also have 6 GB of Landsat data covering the whole state of Florida (1995-1996 years)
  • GOES 8 Data
    Real time Weather data from the GOES 8 satellite.

  • Daily collect of CONUS Images is around 1.2 GB.
  • Digital Aerial Photography
    Digital Aerial Photography (DOQ) from the Miami-Dade County region.

  • We have about 20 GB data of Digital Aerial Photo.
  • AVHRR Data

  • We have about 60 GB of AVHRR data.
