GIS Day 2013 - DWR TO32
Transcript of GIS Day 2013 - DWR TO32
2,700 square miles of spatial data
Translate hydrologic and hydraulic data between numerous H&H modeling platforms
Create informational maps of 200-year floodplain
Create animation of 2D model results
Automating the H&H engineering environment
An overview of how Water Resources used out-of-the-box thinking to meet a crazy deadline and turned it into a full-featured GIS workflow that spanned desktops, servers and the web.
GIS: Smarter, not Harder...
"How it used to be done..."
Each H&H model pre- and post-processed manually.
Data conversion performed using a combination of Notepad and Excel.
Inconsistent documentation (depending on engineer, mileage may vary).
Utilizing sub-consultants required them to be in-office and plugged into the network
IT's greatest nightmare
3 month deadline from project kick-off.
8 study areas to be processed.
Need to collaborate with and manage 5 sub-consultants.
An unknown amount of levee breach simulations would be required.
An unknown amount of data to be managed and documented.
GIS to the rescue!
The H&H software used by the engineers have one thing in common:
"The ultimate inspiration is the deadline."
To utilize a common software platform to manage and process the mass amount of information that needs to be shared across multiple incompatible software suites. Processes and workflows can be
The Crazy Idea...
developed to improve efficiency and accuracy while minimizing downtime.
But what does
The GIS team was given a crash course on the various pieces of software involved and tapped into the collective knowledge of the team to better understand what each one does. Once the pieces were dissected, a few trends started to surface...
Most H&H software kept the input and results as plain text files.
If the results were stored in a binary format, there were existing API's that could be utilized to output the format into something that was easily digestible by Python.
Post-processing of data files could be automated using web-services called from a web interface.
Manage various H&H model data input and output
Plot and QC output from H&H models
Generate 200+ breach animations using GIS
Track status and stage of model through entire workflow
Notify project managers, study-area team and Independent QC (IQC) via e-mail updates as processes were completed.
The best way to understand something is to see it in action.
Demo to cover...
Automated HEC-DSS Processing via web-upload
Grid Selection for use in input files for FLO-2D
Status Page for all study areas.
