Sewall awarded $1.3 Million contract to Map Puerto Rico

James W. Sewall Company recently signed a $1.3 million contract with the Centro de Recaudacion de Ingresos Municipales (CRIM) to complete the first digital parcel map of the Commonwealth of Puerto Rico. Sewall will coordinate the project, totaling more than 800,000 parcels in a 8,959-square-kilometer area, with the Canadian firm Eastcan Geomatics Consultants, Limited, which is under separate contract with CRIM. Utilizing existing planimetric mapping and digital orthophotography from 1997-1998 aerial photography, Sewall will rectify parcel data from CRIM-supplied scans of cadastral maps, convert the data to vector format, and create new parcel IDs. The 14-month project will produce a digital cadastral data set with greater consistency, accuracy, and completeness. Final delivery of the data will be at three scales (1:1000, 1:2000, and 1:8000) in MicroStation .DGN file format. A division of the CBCL Group of Companies, Eastcan Geomatics specializes in GIS development, data conversion, and photogrammetric mapping. Founded in the 1950s, the Nova Scotia firm has completed over 3,500 projects for public and private sector clients across Canada and abroad.
