Mid-West GIS has been awarded a contract in partnership with The Sidwell Company to collect the City of Portage sanitary sewer system. This data will be collected with Real Time Kinematic (RTK) GPS data collectors, which provide the highest level of accuracy possible, with sub centimeter accuracy for the x and y values, and sub two centimeter accuracy for the z (elevation) value. Manhole inspections and invert elevations will be collected as part of this project as well. Work will be completed in the Summer and Fall of 2013.
