CALCULATIONS - Short list

MODEL BUILDER SOLUTION

• Four Processes• Streamstats query

• Unzip retrieved data

• Attribute data point

• Unity query and final product

Combination of ArcToolbox tools and Python scripts

Highly recommend taking Melissa Brenneman’s “Creating Models with Model Builder” for basic Model Building instruction.

Creating Needed Tools - PROGRAMMING

Sometimes GIS software needs a little help -

*PYTHON* Programming language VBA programming C++ programming Various others Tools can be created for

modeling using various programming languages.

Intermixed with tools from ESRI, models can do about anything.

Not a simple process Not an instant result as models

and programs have to be massaged for desired results.

Model Builder Symbols

Parameter – input requiredArcToolbox Tool

Resulting OutputPermanent file or intermediate data

Python Script – creating process

Data from STREAMSTATS

Your Input (Tool parameter) Input Discharge point Stream Name

Adds the points UTM coordinates to xml (Tool)

Sends accurate point to Streamstats website to calculate: (Script) Watershed polygon

shapefile Watershed data

Writes data to text file for later use (Script)

Unzip data from Streamstats URL

Unzip the data files from streamstats GlobalWatershedIN.shp –

polygon GlogalWatershedInpoint.s

hp – the point file Streamstats.xml – data file

that defines watershed data

Sets point file for GIS process

Adding Required Attributes for Unity SQL query

Added through Toolbox tools.

For data comparison based on location: Attributes are added

through spatial joins Intermediate steps results

not kept Final shapefile has all

attributes required for next step.

All data comes from shapefiles added to MXD for speed

Could just refer to it through data path, but will limit speed and dependability.

Building the final product

Three Python scripts: One - coordinates all data

required for computations into a text file.

Two - logs into Unity database and does four queries to retrieve data for comparison purposes.

Three - takes all data from sources and creates a five tab spread sheet.

DDL.xls is final product with all data requirements for engineering designs.

Automated Peak Discharge Determination System MXD

BASE Map for APDDS Model is run by right

click and open DischargeCalc

Will pin point work area by zooming in.

Counties outlined, as you zoom in maps will

appear as background Streams are depicted by

large blue pixel lines when zoomed in far enough

Opening and Running MODEL

Zoom into the site Make sure you are

in enough to display the blue pixel lines!

Right click DischargeCalc in TOC

Select “Open”

Project Selection and Stream Name

Select your Discharge Location: Select point on stream You must be on blue

pixel! Type Name of stream

Spelling critical! Must spell out stream

type Creek River Ditch

You can not abbreviate! Space between Name

and type required.

MODEL RUNNING

Once you hit OK DischargeCalc Dialog

Box will appear This box will show

which step in the model the process is on.

Any error messages will show in “RED” print and describe the error.

Database and connectivity errors can result in this model not completing.

Error problems need to be reported to me for troubleshooting.

Creating the Final Product

A Warning: will appear when

the data is being written to a spread sheet.

Press OK no matter what it says!

This Warning may come up several times

Continue to accept by pressing OK.
