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 1_getNWISSites.py

• takes about 90 minutes to run (with 16GB RAM Intel Core i7-3720QM)
• queries NWIS site service for sites, adds them to a fileGDB
• fileGDB feature classes are referenced within MXDs for each site type

2. Run script to create new tile cache (tile-creation/2_generateTileCache.py)

python 2_generateTileCache.py D:/

• takes about 70 minutes to run (with 16GB RAM Intel Core i7-3720QM)
• 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

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

python 3_updateS3Bucket.py d:/cache s3://nwismapper

• takes about 8 minutes to run
• loops over each folder in tile cache location, recursively deletes from s3 bucket then re-uploads new cache
