<br />corridor, a reliable geodetic control network had never been established,
<br />The BOR remote sensing division contracted Horizon's mapping to establish GIS
<br />map coverage's using photogrammetric methods. David Evan's and Associates established
<br />GPS control points, and ground control points were traversed and paneled by Banner and
<br />Associates.
<br />In 1991 Joseph Mihalko (NPS surveyor) occupied the Banner ground control points
<br />for a soil mapping project by the USGS. He found that the control points did not meet
<br />their claimed accuracy and precision. As a result, GCES established a survey department
<br />to correct all previously established survey control as well as meeting all the research needs
<br />of the fubJre.
<br />The Survey department uses a variety of technology to assist in accomplishing its
<br />mission in a timely, cost effective manner that utilizes a minimum amount of personnel.
<br />These technologies include:
<br />. Global Positioninl!: Systems
<br />To include hand-held autonomous units, Static Differential, DGPS, RTK, as well as post-
<br />processed solutions.
<br />. Conventional Survey Technololrl
<br />To include Total Stations, electronic data collecters, Rangefinders, EDM's, etc.
<br />. Hydrolmlphic TechnolojO'
<br />To include hydroacoustic and scan sonar, GPS and range/azimuth positioning, automated
<br />hi-speed data collection, seabed classification, and acoustic dappler data.
<br />. Maps and Mappinj! Products
<br />To include pJ,mnimetric maps, Digital Terrain Models, Area and surface calculations,
<br />Volume calculations, change detection, habitat maps, and predictive modeling.
