Data Conversion

SGS Infotech offers comprehensive solutions globally. These include solutions and services for creating and updating digital geospatial databases.
One of SGS's key strengths is its ability to convert large volumes of paper maps and drawings to digital format with quick turn-around times. SGS are capable for managing complex conversion projects, which require creation of data from multiple sources of varying scales, vintages, and quality.
These sources could be a combination of topographic maps, CAD drawings, satellite imagery, aerial photographs or observations from field surveys. SGS's integrated processes for conversion include scanning, digitizing (heads-up and tablet), data layering, fitting/geopositioning, statistical batch quality assurance/quality control, and translation into final output.
Parcel Mapping
Parcel mapping services is one of the most important aspects of Geographic Information System (GIS). Strict requirements are needed for services in parcel mapping for the parcel map must be bereft of any error.
Parcel Mapping is the process in which land parcels are created. These maps comprise of polygons which are created from the base map, which shows the details of the ownership of the properties and related information. The base maps are the cadastral maps showing each individual plots in different sub divisions. The land parcels are the fundamental data layer on which different data are referenced.


SGS have professionally skilled team to execute parcel mapping and related projects with precision that fulfill client’s requirements in unbeatable time frame and competitive cost.
Purpose:
- To maintain an official cartographic record of land surveys
- Helps in evaluation of taxation and assists to keep ownership records.
- Used for town planning
- Land use change
Process:
- Scanning of paper map
- Identify and collect ground control points
- Geo referencing the scanned map
- Database design
- Digitization
- Quality Check
- Quality Assurance
Topographic Mapping

Topographic mapping services are the most widely used category among all maps. In topographic maps, the contour lines are used to show the elevation and shape of the land. This feature distinguishes topographic maps from all the other kinds of maps.
Topographic Maps are essential instruments for a variety of monitoring and planning activities. compatibility of topographic mapping services. Even the government departments opt for digital mapping information for their networks.
SGS Services experts are working on large-scale thematic and topographic mapping projects for clients around the globe. Projects can be reliably designed to time constraints and budget lines, and SGS services usually relies on in-country mapping expertise in the course of such projects.
Topographic mapping has been an integral part of a country's cartography.SGS produce Improved information to deliver new maps. World wide acceptance of computer produced maps has accelerated the use of computer compatibility of topographic mapping services. Even the government departments opt for digital mapping information for their networks.
Cadastral Mapping

The Cadastral maps are a comprehensive register of the detailed real property of an area. This includes the precise location, dimensions, and other geographical classifications of properties, and individual parcels of land.
Cadastral mapping is done from hard copies of the administrative maps, which specifies the details of each plot, roads, railway lines, water bodies, vegetation, etc. Cadastral mapping leads to effective management of public land records. The cadastral maps are linked with a backend database which has details of each plot, and their attributes.
SGS undertakes large scale cadastral mapping projects which includes
- Scanning of hard copy maps
- digitization of the maps using proper layer structure
- Geo-referencing the individual maps
- Merging the individual cadastral maps to a single map pertaining to a specific area.
Cadastral maps also show additional details, such as survey district names, unique identifying numbers for parcels, certificate of title numbers, positions of existing structures, section or lot numbers and their respective areas, adjoining and adjacent street names, selected boundary dimensions and references to prior maps.
Contour Mapping

Contour are very important documents as the government and industrial mechanisms are increasingly employing the services of contour mapping systems to control floods, forest fires, real estate planning and development, and a host of other issues.
Contour analysis depicts the weather and oceanic conditions which portray the actual environmental situations which is used ecologists and weather forecast department to forecast the futuristic weather, they show the height of ground above Mean Sea Level (M.S.L.) in either feet or meter and can be drawn at any desired interval.
We at SGS understand customer-collected data using specialized software to generate bathymetric maps. These accurate, geospatial models reveal the complex bathymetry and morphological charac-teristics and allow it to be graphically represented.Our staff also can use the resulting digital model to perform additional analysis.
Landbase Mapping

Land base is a vector mapping product that depicts core land cover to a level of detail and extent. Key features of the landscape such as on road location, surface condition, road centerline position, and a detail on the multitude of highway signage related to transportation routes and provide classification down to individual property level. The new land cover product is a vector map produced using the latest digital aerial imagery and object based classification technology .We at SGS Use genuine software to develop the land cover classifications, land-based GPS positioning been used with marginal success as a mapping data acquisition tool to accurately position Planimetric features in open, unobstructed areas. Our Land Base is designed as a framework, for used within a GIS system, to allow specific spatial queries-what percentage of this area is covered by trees-as well as allow the addition of further detailed classifications. These maps are made as per the clients Data model and specifications and delivered as per specific formats (Tab, Shape, Small World, etc.). We have been providing these services to our existing clients for last several years with a full quality satisfaction and cost effectiveness.
Image Processing

Image processing services is a type of sophisticated information processing in which both output and input are made of photo-like images and video frames. Services of image processing are used in many areas such as from satellite images creating weather maps.
SGS is an adept at processing high-resolution imagery into quality raster data products. This involves removing distortions in the images to ensure that outputs are of the highest clarity, resolution, and color. Our service offerings include geo-referencing, ortho-rectification, mosaicing, color balancing, and cutting to specified output formats. SGS is able to produce a seamless raster data product from multiple image tiles.
We have the ability to handle large volumes of images, automate most of the data management processes, and pass on the productivity gains to the client in terms of fast turn-around- time and competitively priced solutions.
Image Classification

The intent of the classification process is to categorize all pixels in a digital image into one of several land cover classes, or "themesThe objective of image classification is to identify and portray, as a unique gray level (or color), the features occurring in an image in terms of the object or type of land cover these features actually represent on the ground.
SGS employs a variety of automated classification methodologies, supplemented by manual techniques, to generate image classifications. These methodologies consist of land-cover/land-use classifications and change-detection analyses, including binary change maps and thematic maps of land-cover changes. We work closely with you to define the classifications' thematic scheme and provide you with summary statistics, assessments of the resulting maps' accuracy, and poster-quality graphics for your use.
