Mostly-Automated Procedure for Line-Extraction / Simple Yet Robust Universal Parametric-Orthorectification Welcome to the MAPLE_SYRUP Homepage An orthorectification software extension and procedure was developed using photogrammetric principles to remove existing soil survey base map errors. The extension uses a USGS digital orthophoto (DOQ data), a scanned soil survey mapsheet, and a USGS 30-meter digital elevation model (DEM) as inputs. Existing commercial software could not be utilized because inputs such as focal length, fiducial marks, etc., could not be gathered from the soil survey map base. The orthorectification extension uses a statistical model to produce a geometrically correct soil survey map base.   Download MAPLE_SYRUP As a result of continued interest in the SYRUP rectification program developed at the Soil Landscape and Analysis Lab - University of Minnesota, we will be providing the original program on our website. MAPLE_SYRUP is an outdated process developed around the UNIX-based program SYRUP that three-dimensionally rectifies aerial photography (ortho-rectification). Only the program code for SYRUP will be provided, in its native UNIX platform. Any interest in the MAPLE_SYRUP process can be directed to the website. The file will be provided as is, with no additional support, implied or intended, besides the documentation already included on our website. We will not accept inquiries regarding the installation, use, or products of this program. Please consult the provided documentation for any questions. Thank you for your interest. Funding for this project was recommended by the Legislative Commission on Minnesota Resources (LCMR) from the Environmental and Natural Resources Trust Fund. Funding for this project was provided by the LCMR. Products were developed in the Soil Landscape and Analysis Lab, Department of Soil, Water, and Climate, at the University of Minnesota.
