Our professional team can deliver GIS services including:
Parcel Mapping
GIS technicians at SAM, Inc. have rectified parcel data with associated identification attributes to 1.0-meter Digital Ortho Quarter Quads for several countywide mapping projects. Real-time QA/QC procedures ensure the highest degree of accuracy possible. Technicians are able to import data from various formats and integrate it into a GIS using ESRI’s ArcGIS/ArcINFO suite of GIS applications.
Utility Mapping
Using Trimble Pro-XRS mapping grade receivers, field crews are quickly able to locate physical assets or underground utility markings to sub-meter accuracy. Office staff then exports this data to database file format and performs QA/QC procedures to check for errors or missing data elements. The data is then imported into ArcMAP. SAM, Inc.’s experienced staff has developed workflow procedures that produce high quality data.
Database Population
Our GIS technicians have considerable experience developing data dictionary files ranging from a few features with minimum attributes to comprehensive files with numerous attributes. Trimble Pro-XRS mapping grade receivers and TSC-1 data collectors are used to collect the feature data. Data are processed through Path Finder Pro-Office, exported to database form, and subjected to rigorous quality control procedures. After completion of QA/QC, the data are converted to client-specified file formats. The database files can then be linked to associated digital imagery in ArcMAP, resulting in a superior product.
