The Role And Road to High Quality DataFEATURE DATA (GIS) PARAMETRIC DATA (tabular media data)

1980’s Create standards, begin pilot framework production

1990’s Framework production. Begin Regulated Site GPS point collections. Metadata.

1995-97 Data Distribution: CD then Internet

2000 GIS Mapping on Internet (ArcIMS)

2003 Interactive Mapping on Intranet. Conceptual model development for Web2.0.

2009 Web2.0 Interactive Mapping linked to Media Reports on Internet…

NJ-GeoWeb

1995 Create Normalization Standards by media (air, water, land). Create

NJEMS.

1996 Begin data normalization by program by media

2000 Populate new NJEMS with Normalized Data

2002 Institute Report Generation Framework

2004 Begin e-Permitting Efforts

2008 Post “Live” media reports by Program Interest on Internet

2009 Link Program Interest Reports to Geospatial Applications on Internet

CONSIDERATIONS:

•Cost - Time•Resolution and Accuracy of Final Product

STEREOSCOPIC - (Photo Interpretation)

•Delineate to the aerial photo•Digitize lines •Digitize control points •Rectify to a base

IMAGE PROCESSING

•Mapper “Trains” the IP software to recognize unique stands of vegetation.

DIRECT DIGITAL PROCESS

•Interpret directly on the computer screen using multiple sets of imagery and ancillary data sets.

National Land Cover Dataset LULCin California

Problem: Many clients will search and find only small scale satellite data to try and solve site specific issues. Mixed or noise pixels can be time consuming to resolve.

These data are suitable for at site decision making with tough-books or mobile smart phones.

Advantages to High Resolution GIS Data and Normalized Parametric Data in Web2.0 Apps

Create once, edit manyBetter decision-makingInformed citizenryInformed clients (those regulated)Make better decisions fasterMuch better model results (watershed, build out, runoff, etc)Ability to do on the ground decision making with iPads or smart phones.Enhances mobile (smart phones) as a decision-making device in the field.Improved decision-making improves iterative small decisions which in

the aggregate improve environmental conditions.Enhances compliance and enforcementSaves time and money

Increases ability of smaller staffs to do maintain and improve workflows

National FRAMEWORK for Land Use Land Cover

Land Use Land Cover is the #1 download from NJDEP.

Since LULC is critical for so many environmental analyses and models.. A national discussion needs to begin on how states (including counties and municipalities) can work with federal agencies to build a consistent more detailed LULC framework.
