3. Recommendation for managing spatial data
0 Recommended Coordinate System EPSG 3857 (Global web
Mercator Auxiliary (Sphere))
0 Use folder/directory structure to store raster imageries
0 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 folder
0 Use File Geodatabase/PostGIS to store vector files
0 Follow the new naming conventions

4. Naming Convention
Spatial Data Types Naming Convention Example
01-Satellite Imagery SatelliteName*&Sensor_Area/path&rowc_Date* LSETM_p44r57_0811201
02-Processed/Products ProductName*_areac_Date* NDVI_LK_2002
03-DEM DEMname*_area/tilenumberc_version/date SRTM_LK_2.0
04-Map NameOfMap*_areac_version/date GLULC_Global_2.0
05-Scanned Products ScannedProductType*_area/seriesc_version/date toposheet_LK51_1997
06-Vector Data FeatureName*_areac_date mainroad_colombo_lk

5. 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
