Geospatial Services Manager

Jun 2014 - Present
As the Geospatial Services Manager my responsibilities include the management, production, and development of our GIS and Remote Sensing projects for airports, municipalities, and private residences across the Rocky Mountain Region. Airport Projects include Airports GIS surveys such as Airport Airspace Analysis Surveys, Design/As-Built Projects, and Existing Airport Data Projects. I am responsible for managing the projects, submitting the data, and working with the NGS and FAA to insure a smooth verification of the data.I have then been using the AGIS data to develop our Airport Layout Plans in a GIS environment. Over the last 4 years I have been transiting our ALPs from a CAD template to a GIS environment. This has allowed for the development of models to streamline Part 77 Analysis and Critical Profile Lines. Completing the ALPs in a GIS environment allows for the use of publicly available spatial data and the ability to easily share the data with clients and municipal leaders. Furthermore, the ALP sheets are being transformed into interactive online mapping applications. These applications provide the ability for a user to interact with the ALP.As the leader of our Remote Sensing Team, I have been responsible for the processing of the imagery and the classification of point clouds to develop highly accurate topographic surfaces. The workflows I have developed allow for the removal of vegetation, structures, and any other non-ground feature to produce topographic data in almost any environment. Some examples of Remote Sensing Projects include airports ranging from small 200 acre surveys to 1600 acre surveys resulting in 1-foot contour intervals. I have provided orthomosaic and topographic deliverables for road projects, landfills, quarries, salt piles, construction projects, cemeteries, private residences, water tanks, and many other miscellaneous projects.

Senior Engineer Assistant

Jul 2012 - May 2014
As a Senior Engineer Assistant for the Town of Grand Island I used my experience and knowledge as a licensed land surveyor and geographer to complete municipality projects for the engineering department. Using a total station, level, and GPS-RTK unit I led a crew in the field for the collection of boundary and topographic measurements which lead to my involvement in each project from field to finish. The field data was used for designing utility and transportation projects, as-built drawings, and utility information for updating and maintaining our GIS shapefiles and database. I used CADD and GIS software for drafting and designing bike paths, waterlines, storm drainage, utility locations, deed sketches, easements and miscellaneous drawings as needed. When I wasn’t drafting in the office I was writing and verifying legal descriptions, preparing proposals, completing building permits, maintaining the Web Mapping Application, responding to benchmark requests, and working with co-workers to find solutions for questions and complaints from residents of the town.While working in the engineering department I have had the privilege of designing a new street guide of the Town of Grand Island for public sale. Recently I have interpolated LiDAR data and have added a 5’ resolution Digital Elevation Model to our GIS. The high resolution topography is being used for planning and estimating purposes for potential projects and earth volume calculations.
