Generate new NWIS mapper tile cache

required software

ESRI ArcGIS Desktop ~10.3.1
Python 2.7
Python Pillow image library
AWS CLI

1. Run script to pull NWIS sites from USGS waterservices (tile-creation/1_getNWISSites.py)

python generateTileCache.py
  • takes about 3 hours minutes to run
  • queries NWIS site service for sites, adds them to a fileGDB
  • fileGDB feature classes are referenced within MXDs for each site type
  • this is a wrapper script that generates an ESRI tile cache, cleans it up then converts to TMS tiles
  • output can be uploaded directly to s3

2. Upload to amazon S3 (tile-creation/3_updateS3Bucket.py)

  • check to make sure paths are correct
python updateS3Bucket.py
  • takes about 8 minutes to run
  • loops over each folder in tile cache location, recursively deletes from s3 bucket then re-uploads new cache
