A GEOGRAPHICAL INFORMATION SYSTEMS.

NARA GROUP is a global GIS consulting company providing geospatial technology solutions,modeling & analytics, and IT services.

LiDAR Mapping Services

                                                   LiDAR is a surveying method that measures distance to a target by illuminating that target with a laser light. NARA'S Enterprises ranked among top LiDAR Mapping Companies in India for outsourcing services. We at, NARA'S, combines LiDAR with GIS data and other survey information to generate complex geomorphic structure mapping products, advanced 3D models/earthwork profiles, rendering of structures, and many additional high value mapping products. NARA'S, offers variety of services related to post processing of LiDAR point cloud data which includes BE (Bare earth) classification, utility classification, topographic and land use classifications.
NARA'S outsourced mapping services include mapping from Light Detection and Ranging (LiDAR) survey data. Both ground and aerial LiDAR data can be integrated. Aerial data gathered in this way uses laser reflection from the earth's surface captured by sensors in an aircraft. This allows the precise elevation and location of objects to be determined on different scales, making aerial LiDAR an effective approach for creating accurate topographical maps.

                       • Workflow Management Systems (WMS).

Geo-Reference

In NARA'S the internal coordinate system of a map or aerial photo image can be related to a ground system of geographic coordinates. The relevant coordinate transforms are typically stored within the image file (GeoPDF and GeoTIFF are examples), though there are many possible mechanisms for implementing georeferencing. The most visible effect of georeferencing is that display software can show ground coordinates (such as latitude/longitude or UTM coordinates) and also measure ground distances and areas. In other words, Georeferencing means to associate something with locations in physical space.  Georeferencing may be applied to any kind of object or structure that can be related to a geographical location, such as points of interest, roads, places, bridges, or buildings.Geographic locations are most commonly represented using a coordinate reference system, which in turn can be related to a geodetic reference system such as WGS-84..

Scanning & Digitisation

                            At NARA GROUP we are creating era of digital world, hard copies need to be converted to digital form before being used for any service, application, etc.
Digital maps are easy to maintain, take up less space and can be preserved for a longer time. We have been doing projects where scanning and digitization of images, maps, documents and more are pre-requisite.
Our services include management, alignment, scanning & indexing of digital data. We take care of each aspect to preserve the originality of the document. We also provide solutions such as Document Management Systems for easy retrieval of the scanned & digitized documents.

Photogrammetry

Photogrammetry is the science of making measurements from photographs, especially for recovering the exact positions of surface points. Photogrammetry is as old as modern photography, dating to the mid-19th century and in the simplest example, the distance between two points that lie on a plane parallel to the photographic image plane, can be determined by measuring their distance on the image, if the scale (s) of the image is known. NARA offers photogrammetric services from Aerial Photographs and Stereo Satellite Images using the latest aerial and satellite photography equipment, software and state-of-the-art technology.
In NARA 'S provides photogrammetric solutions to meet the user’s needs with the best quality and at a globally competitive price. The solutions are tailor-made based on the specific requirements of the clients.
• Digital Aerial Triangulation for Aerial Photos/Exterior Orientation(EO) for Satellite Imagery.
• Topographic / Planimetric Mapping and Updating.
• DEM/DTM / Contour Generation.
• Digital Ortho-photo Generation/ Mosaicing / Tiling.

FIELD SURVEY

A field of applied statistics of human research surveys, survey methodologystudies the sampling of individual units from a population and associated techniques of survey data collection, such as questionnaire construction and methods for improving the number and accuracy of responses to surveys.

Topographic Survey/Contour Survey

Detecting the changes in topography can have a great influence on determining the nature of features in a geographical survey. It is vital to produce a detailed and complete topographical survey as part of the field survey of any given site.

IMAGE PROCESSING

At NARA GROUP we are high resolution imagery can be processed expertly into quality raster data products. This involves removing distortions in the images (georectification, orthorectification) and ensuring that the output is of high quality in terms of clarity, resolution and colour. A seamless raster data product is then derived from multiple image tiles.The activities include removal of distortions in images (geo-rectification, ortho-rectification) and ensuring that the output is of high quality in terms of clarity, resolution, and color. We are adept at handling large volumes of images, automating many of the data management processes in this activity, and pass on the gains in productivity to the client in terms of fast turnaround times and competitively priced solutions. We also create value-added image products from satellite imagery, including pan-sharpened multi spectral imagery products, natural color pan-sharpened products, seamless mosaics for satellite images and land use/land cover mosaics for large areas.

URBAN DEVELOPMENT & PLANING

Urban Development & planning is a technical and political process concerned with the development and design of land use in an urban environment, including air, water, and the infrastructure passing into and out of urban areas, NARA GROUP such as transportation, communications, and distribution networks.Urban planning deals with physical layout of human settlements.The primary concern is the public welfare,which includes considerations of efficiency, sanitation, protection and use of the environment,as well as effects on social and economic activities.Urban planning is considered an interdisciplinary field that includes social, engineering and design sciences.

Data conversion

                                 

           Data conversion is the process of moving data from one format into another, whether it is from one data model to another or from one data format to another. With large amounts of geographic data available for use, it is more cost-effective to convert the data from one format to another than re-create it .At NARA GROUP We are a specialized team of design and drafting engineers who generate the desired digital data while following the latest technologies and tools. One of the most valuable aspects in is the digital representation of an image. NARA GROUP has the capability to convert hard copy into a wide range of electronic formats. Our integrated processes for conversion convert architectural, mechanical and various technical drawings, maps and other types of line artwork into the desired formats with fine quality of high-end products. In some cases, the data is already in a digital format, but often this data is not compatible with the current or other system.

CREATING DATA IN 3D

Three-dimensional viewing can provide in depth details that would not be apparent from a 2D map.3D is not only for viewing purposes but can be useful for many professional analysis and applications like watershed management, landslide hazard zonation, urban planning, and management.We have an experienced team for generating 3D models using stereo images. We also offer services of generating DEM from stereo imagery, ortho-rectification of images, 3D digitization and capturing contours in different intervals.With the help of topographic maps, NARA GROUP has created Digital Terrain Models (DTM), Digital Elevation Models (DEM) and Triangulated Irregular Network (TIN) for different domestic and international clients.
