Recommendation for managing spatial data
0Recommended Coordinate System EPSG 3857 (Global web Mercator Auxiliary (Sphere))
0Use folder/directory structure to store raster imageries0Create 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
0Use File Geodatabase/PostGIS to store vector files0 Follow the new naming conventions
Naming ConventionSpatial Data Types Naming Convention Example
01-Satellite Imagery SatelliteName*&Sensor_Area/path&rowc_Date* LSETM_p44r57_0811201

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
01-Satellite Imagery0All Satellite Data0Raw data with original band sequence0Composite day imageries0Radiance/ Reflectance imageries0 Separate/ Stacked scenes?0Don't put satellite imagery without clear metadata (date,
bands sequence, sensor)
02_Products0NDVI, ET, EVI, VI, Snow Cover etc products from satellite0Any valuable intermediate products derived from satellite
imageries
04_Map0GIAM0 Landuse, Landcover, Forest Cover0Distribution maps (Landscan Population, temperature,
precipitation, snow melt) derived using multiple sources0 Slope, Flow direction
05_Scanned_products0Any scanned georeferenced materials0 Toposheets, Aerial photo, Printed maps
