GIS Data Acquisition, Data Creation, Data Conversion, Data Analysis, and Metadata Creation Services
GIS data crucial to project success exist in various locations that can be difficult to track down. SGS specializes in GIS data acquisition and GIS data creation services for fulfilling any GIS mapping needs. GIS datasets such as parcel data, soils data, wetlands data, stream network data, aerial photography, LIDAR (Light Detection and Ranging data), Digital Elevation Models (DEMs), rainfall data, flood data, land use data, streets data, state and federal environmental conservation data, and countless others are spread across the internet. SGS has the knowledge to acquire this data for any project we work on or provide it for any project needs your company may have. SGS maintains in storage many Gigabytes of data especially relevant to North Carolina projects.
In addition to acquiring data, SGS has the capability of generating high resolution DEMs (to 5') from LIDAR data, creating parcel or other data from COGO (coordinate geometry) survey information, and creating GIS datasets of anything that can be mapped via GPS.
GIS data are available in a variety of data formats, some of which require conversion from old data formats or non industry standard data formats to be functional for a GIS project. SGS can convert GIS data from any format into industry standard GIS data formats functional for use in your GIS project. GIS data are also often georeferenced to various coordinate systems which can prove confusing to the inexperienced GIS user and can cause aggravating problems when trying to combine GIS data from different sources into a single GIS project. SGS has a thorough understanding of coordinate systems and the experience to get all of your GIS data into a desired coordinate system.
GIS data by themselves rarely provide the complete information suite required to fulfill the goals of a GIS project and generally must be analyzed and processed to support GIS project needs. SGS uses ESRI's ArcGIS software platform and has the capability to perform both standardized and customized GIS data analyses. SGS staff are highly skilled in the use of ESRI standardized tools such as Geoprocessing and ArcToolbox tools, and SGS staff have the capability of constructing customized ArcToolbox tools and creating custom data processing models for use with ESRI's Model Builder.
SGS understands that GIS data is not complete without containing information as to its content and means of creation. A crucial aspect of any SGS GIS data deliverable is FGDC compliant Metadata. SGS creates Metadata for every GIS data deliverable and ensures FGDC compliance using the standard Metadata Parser utility.
