Instructors
John Cooke joined Wetland Studies and Solutions, Inc. in the fall of 2009 after working as an independent consultant and AutoCAD® instructor for over twenty years. John presently operates the CivilTraining, LLC division of Wetland Studies and Solutions, Inc. (WSSI), and supports Engineering, GIS and Surveying technology efforts within the office and to clients nationwide. He has been continuously affiliated with Autodesk Civil/Survey applications since 1989, functioning initially in development and then in consulting and training roles. He has an extensive background in the development, implementation and training of Autodesk AEC Civil Engineering, Surveying, GIS and BIM solutions and has provided training to thousands of individuals nationwide, assisted numerous clients in implementing Civil software, CAD standards and practices, and provided project consulting to many clients in unusual or challenging project applications. Within WSSI, he participates in development efforts for Engineering and Survey automation, including the creation of custom software for stream restoration based on AutoCAD® Civil 3D®.
Yeoanny Venetsanos joined Wetland Studies and Solutions, Inc. in the winter of 2005 and has over twelve years of professional experience in Geographic Information Systems (GIS), Computer Aided Drafting (CAD) systems, land surveying, and natural resource management. Yeoanny provides technical training and consultation services for clients interested in leveraging both GIS and CAD technologies to meet business requirements. Yeoanny is skilled in the practical use of Esri® ArcGIS and Autodesk® A CAD® l i l i il i i d l d i bl d i li d L dAutoCAD® to solve environmental, civil engineering, and land surveying problems and is a licensed Land Surveyor in the Commonwealth of Virginia and the District of Columbia, a Certified Mapping Scientist ‐GIS/LIS through the American Society for Photogrammetry and Remote Sensing (ASPRS), and a Geographic Information Systems Professional certified through the Geographic Information Systems Certification Institute. Yeoanny is a 2007 graduate of the Virginia Land Surveying Apprenticeship program and is currently an instructor for the program. Yeoanny also received a Graduate Certificate in Geographic Information Sciences from George Mason University in 2009.

GIS Concepts: Map Projections / Coordinate Systems
Section: 51:3‐7: Official survey base established; plane co‐ordinates
51:3‐7. The official survey base for New Jersey shall be a system of plane co‐ordinates to be known as the New Jersey system of plane co‐ordinates, said system being defined as a transverse Mercator projection of the Geodetic Reference System of 1980, having a
t l idi 74` 30' t f G i h hi h idicentral meridian 74` 30' west from Greenwich on which meridian the scale is set at one part in 10,000 too small. All co‐ordinates of the system are expressed in meters, the x co‐ordinate being measured easterly along the grid and the y co‐ordinate being measured northerly along the grid, the origin of the co‐ordinates being on the meridian 74` 30' west from Greenwich at the intersection of the parallel 38` 50' north latitude, such origin being given the co‐ordinates x=150,000 meters; y=0 meters. The precise position of said system shall be as marked on the ground by triangulation or traverse stations established in conformity with the standards adopted by the National Geodetic Survey, formerly the United States Coast and Geodetic Survey for first and second‐order work, whose geodetic positions have been rigidly adjusted on the North American Datum of 1983 or the most recently published adjustment by the National Geodetic Survey, and whose plane co‐di t h b t d th t d fi d Th N
15
ordinates have been computed on the system defined. The New Jersey co‐ordinate system defined by the North American Datum of 1927 may be used concurrently with or in lieu of the system defined by the North American Datum of 1983 for a period of 36 months after the effective date of this amendatory act, P.L.1989, c.218.
Standard conversions from meters to feet shall be the adopted standards of the National Oceanic and Atmospheric Administration.

GIS Concepts: Reference Mapping

GIS Analysis: Selection Query
18
10
GIS Analysis: Clip
• Extracts input features that overlay the clip features; use this tool to cut out a piece of one feature class using one or more of the features in another feature class as a "cookie cutter"
19
GIS Analysis: Intersect
• Computes a geometric intersection of the input features. Features or portions of features which overlap in all layers and/or feature classes will be written to the output feature class
20
11
GIS Analysis: Union
• Computes a geometric union of the Input Features; all features will be written to the Output Feature Class with the attributes from the Input Features, which it overlaps
21
GIS Analysis: Buffers
• Creates buffer polygons around input features to a specified distance
22
12
GIS Analysis: Merge
• Combines multiple input datasets of the same data type into a single, new output dataset
23
GIS Analysis: Dissolve
• Aggregates features based on specified attributes
