Contractors: Getting the CleanestGeospatial Data Possible

Urgent News from FoxNewsNetwork

E.O. 12907, signed by President Bush onMarch 31, 2008, states:

“Beginning April 15, 2008, all federal geodatabases are required to have FGDC metadata for:

each feature class, each feature data set, and the geodatabase….”



The Goal:

Deliverables that I don’t have to edit

That upload into Park’s Geospatial Library

That upload to NPS Data Store


• Background Example

• The Issues

• The Solutions

• The Tools

• The Results

Summary


• No Involvement by Park with Contract

• Multi-Year Project, Same Contractor

• Many Field Data Collectors

• Miscommunication of Requirements

Background Project Example


Too Many Shape Files with Attribute Errors

Too Many Metadata Records by Contractor

Approx. 2 weeks Park spent editing data

Example Results:

Summary


Different Data Dictionaries

Inconsistent Field Values/Attributes

Misspelled Attributes

Unnecessary Data

Multi-Year Project Problems

The Issues


Leading Space(s)

Capital “O” for Zero

One too many digits in date field

How was data created?

Spelling Errors

Missing Values

Issues: Common Results



• The Issues

• The Solutions

• The Tools

• The Results

Summary


NPS National Standards &

Park-Specific Standards

Trimble Export Routine (if applicable)

Ask for Documentation of Protocols before contract signed

******************************************* “No Good Data, No Good Pay”

The Solution: Written Contract


Provide Supporting Park Data & Metadata to Contractor

Set the Example

Assist w/ GPS Data Dictionaries

Provide Data Schemae.g., List of Required Fields

The Solution: Assistance


Provide Example DeliverablesGeodatabase, Metadata Record

Review Data periodically before end of project (write into contract)

The Solution: Assistance


Define Your Preferred Data Format:

File GeodatabasePersonal Geodatabase

Shape FileCoverages

Projection/Datum

Solution: Preferred Data Format


ALL CAPS/Initial Caps/Does It Matter?

Solution: Define Field Value Rules


Ex: “Surveyor” Format:



Ex: Date Format: YYYYMMDD

Date or String or Numeric?




Ex: Date in MetadataDate Format: YYYMMDD


Did you know that “Process Step”

is not an FGDC Requirement?

Therefore, do you know how

the data was created then?

Solution


The Solution: Process Step

Require “Process Step” (Metadata) in the Contract:Data Quality Process Description/Software_Version/Date/Contact


• Separate or Combined Data?Who will do that

• Same Data Dictionary? What IF it changes How will it append/merge

Contract needs written instructions addressing multi-year project

Solution: Multi-Year Project



• The Issues

• The Solutions

• The Tools

• The Results

Summary


Review with Contractors:

• Contract Standards

• Define/Provide Data Dictionary

• Data Schema:Values/Attributes Format

Domains/Ranges

Provide The Tools


Review with Contractors:

• ArcToolBox Frequency Tool: unique ID spelling inconsistenciesmissing valuesleading spaces, etc. other ways?

(Access, Excel, SQL, Oracle, scripts?)

Provide The Tools


NPS Metadata Tools & Editor

Provide Tools Linkhttp://science.nature.nps.gov/nrdata/tools/index.cfm

Review with Contractor: Spell Check MetadataParse MetaFind and Replace, etc.

Provide the Tools


Solution & Tools Summary

• Get it In the Contract

• Write the GPS Data Dictionary

• Define the Schema

• Provide the Tools

• Work w/ During Project

• Review the Data Before You Pay


• Have a Party!

• Present to Park Management/Employees

• Thank them officially for a job well done

End of Project
