Sampling grids are an important part of the site delineation process.
GIS staff can produce sample grids with any shape or spacing and
generate grid coordinates. Grid points may then be uploaded into a
Global Positioning System and used by field staff to locate the
selected sample points.
Sample Station Maps
Sample station maps are important in all field sampling studies. Maps
may be produced prior to the initiation of field studies to assist in
identifying specific sampling stations or areas of concern. Maps may
also be produced from data stations recorded in the field using Global
Positioning Systems. Sample station coordinates recorded in the field
can be downloaded to a computer and plotted on aerial photographs and
topographical maps.
Spatial Representation of Data
Maps that show sample stations, grids or transects through a study area
can be produced before sampling is initiated. GIS staff use ArcView®
software to spatially represent data collected in the field. Spatial
representation of sample stations is important when conducting wetland
delineations, habitat mapping, sediment characterizations studies,
water quality studies, and tissue studies. Field data can be plotted
on maps to show spatial relationships between sample stations and
results.
