Geo-referencing / Rectification
Geo-referencing is the process of scaling, rotating, translating and deskewing the image to match a particular size and position.
Geo-reference is the process of defining something existence in physical space or in other words establishing its location in terms coordinate systems representing earth defined through projection systems. It is used when establishing the relation between raster or vector images by determining the spatial location of the geographical features. This procedure is mandatory for data modeling in the field of geographic information systems (GIS). When data from different sources or time periods (like time series satellite images) need to be combined and then used in a GIS application, (e.g. for change detection, assess damages after a natural disaster etc.), it becomes essential to have a common referencing system. One can geo-reference a set of points, lines, polygons, images, or 3D structures (e.g. shape file geo-referencing). This is brought about by using various geo-referencing techniques. Most geo-referencing tasks are undertaken either because the user wants to produce a new map or because they want to link two or more different data sets to the same geographic locations or mapping new features or updates in an existing data.
Geo-referencing Raster Images
A crucial element of any mapping project is registering a map with the correct real world coordinates. This procedure is called geo-referencing. If the maps are not geo-referenced, no other information can be displayed over or positioned under the map coverage.
Depending on the source materials and the specifications of the project, maps can be registered to either a coordinate system or to another base map such as a digital ortho photo.
Geo-referencing Vector Data
Vector data can be geo-referenced (or rubber sheeted) to real world coordinates. Vector data can be either rubber sheeted to match existing base maps or the data may be projected into a specific coordinate system.
SGS offers expert geo-referencing services which include geo-rectification and accurate mapping services for a wide range of industry domains.
Coordinate Geometry (COGO) Parcel Mapping
Full Re-Mapping from Deed/Plat using COGO is the most intensive cadastral product SGS offers. All property ownership documents (deeds, hardcopy maps, right of way plans, subdivision plans etc.,) in the County are optically scanned and indexed. SGS uses this information to build a county-wide cadastral layer, one parcel at a time, using coordinate geometry, or COGO.
We have good experience and capacity to plot parcel from legal description.
All survey calculations are performed with a COGO program, running inside of AutoCAD creating an independent database of the coordinate point numbers. Data is subsequently converted to ArcView for GIS Analysis.
Following process is adopted for COGO mapping
Digitization – Parcel maps are converted from paper to digital format utilizing a combination of digitization, scanning and Coordinate Geometry (COGO) entry from official survey plats.
Conflation – Our best-fit conflation processes improves the accuracy of the parcel maps by rectifying to an accurate base map or ortho photography base.
Parcel Attribution / Linking – Utilizing an exact copy of the official real estate database, our process links each parcel to the Meta data in the geo-database format with no manual re-entry of data.
Maintenance Services – Maps can be kept up to date utilizing our maintenance services via Coordinate Geometry (COGO) entry of survey plats.

Land Use / Land Cover Mapping
The Land cover reflects the biophysical state of the earth's surface and immediate subsurface, thus embracing the soil material, vegetation, and water. Land use refers to man's activities on land which are directly related to the land. Land use and land cover are dynamic. Changes may involve the nature or intensity of change but may also include spatial (forest abatement at village level, or for a large-scale agro industrial plant), and time aspects. Land use/ Land cover changes also involve the modification, either direct or indirect, of natural habitats and their impact on the ecology of the area.
Land Use Land Cover features have been precisely captured through on-screen visual interpretation and digitally on fused very high resolution (0.60 m, Quick Bird) and medium to coarse resolution (LISS IV, LISS III) satellite imagery. Provision of such maps helps town planners in effective and best possible utilization of its resources besides providing a comprehensive view of the total area
SGS has qualified remote sensing professionals with experiences in different domains. The team has developed several processes and algorithm to semi-automate the process of image classification especially to generate Land-use/Land-cover data.
