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
Aerial Information Systems, Inc.
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.

NJ-GeoWeb Displays 2007 Land Use Land Cover and HydroDerived from Heads-Up Digitizing off 1 ft Pixel DMC Imagery
The Fourth Iteration (1986, ‘95, 2002, ‘07, 2012 on the way)
Each polygon has a % Impervious Cover Value in Increments of 5%
2002 Image with land use polygons and codes
2002-2007 LU/LC Update:Direct Digital Process Using Heads-Up Editing
(adding changes directly to the 2002 layer)
2002 Polygon boundaries and codes are retained,2007 Changes are then added

State wide Land Use/Land Cover Statistics 1986-2007 (In Acres)
*includes all wetlands changes, both natural and artificial, and to both natural and disturbed wetlands
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.
The Same Site Using Heads-Up Delineation Technique Showing LULC Using Aerial Imagery and Classic Photo Interpretations and Delineation.
These data are suitable for at site decision making with tough-books or mobile smart phones.
1986 Hydrography (DLG’s)
2002 Hydrography 1:2,400 and 2010 NHD
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.
