Creating Spatial Data Structure

  1. 1. Database Server Directory Sub Directory File Geodatabase/PostGIS Data file database 01_satellite _imagery Satellite Name * 02_productsspatial _data 03_dem Raster_Dataname 04_map 05_scanned_products global global 06_vector regional Regional Name* Feature_Dataname national National Name* basin Basin Name* a.rajah@cgiar.org
  2. 2. Recommendation for managing spatial data0 Recommended Coordinate System EPSG 3857 (Global web Mercator Auxiliary (Sphere))0 Use folder/directory structure to store raster imageries0 Create preview and index (shapefile)for raster images and store it in same folder or store in ‘preview’ and ‘index’ folder which can be inside the same raster folder0 Use File Geodatabase/PostGIS to store vector files0 Follow the new naming conventions a.rajah@cgiar.org
  3. 3. Naming ConventionSpatial Data Types Naming Convention Example01-Satellite Imagery SatelliteName*&Sensor_Area/path&rowc_Date* LSETM_p44r57_081120102-Processed/Products ProductName*_areac_Date* NDVI_LK_200203-DEM DEMname*_area/tilenumberc_version/date SRTM_LK_2.004-Map NameOfMap*_areac_version/date GLULC_Global_2.005-Scanned Products ScannedProductType*_area/seriesc_version/date toposheet_LK51_199706-Vector Data FeatureName*_areac_date mainroad_colombo_lk a.rajah@cgiar.org
  4. 4. Instructions• *-Mandatory• c_Conditional (If it is available then it is mandatory)• Use abbreviations for geographical areas, satellites, sensors and products• Avoid using full name• Avoid more than 30 character for naming• Try to use common standard abbreviation• ‘area’ should follow the hierarchy e.g. local area name_country abbr. no more than two level• If something you think it is really necessary that can be added before date e.g for composite image “8day”• Use “_” (Underscore) for the spaces• Suppose there are too many vector files (~more than 30) in a single spatial database group them all in meaningful way (Recommend to use ISO spatial categories)• If there is any necessary readme/MET file then use the same name which is used for that dataset a.rajah@cgiar.org
  5. 5. 01-Satellite Imagery0 All Satellite Data0 Raw data with original band sequence0 Composite day imageries0 Radiance/ Reflectance imageries0 Separate/ Stacked scenes?0 Dont put satellite imagery without clear metadata (date, bands sequence, sensor) a.rajah@cgiar.org
  6. 6. 02_Products0 NDVI, ET, EVI, VI, Snow Cover etc products from satellite0 Any valuable intermediate products derived from satellite imageries a.rajah@cgiar.org
  7. 7. 03_DEM0 SRTM, ASTER, GTOPO, LIDAR0 Interpolated DEM using spot height or contours a.rajah@cgiar.org
  8. 8. 04_Map0 GIAM0 Landuse, Landcover, Forest Cover0 Distribution maps (Landscan Population, temperature, precipitation, snow melt) derived using multiple sources0 Slope, Flow direction a.rajah@cgiar.org
  9. 9. 05_Scanned_products0 Any scanned georeferenced materials0 Toposheets, Aerial photo, Printed maps a.rajah@cgiar.org
  10. 10. Abbreviation0 Landsat -LS0 MODIS – MD0 QuickBird – QB0 WorldView –WV0 IKONOS – IK0 NOAA – NA0 IRS – IRS0 SPOT – SP0 RapidEye – RE a.rajah@cgiar.org
