Data Conversion

Geospatial data is captured from different platforms and in various formats. It therefore requires constant data conversions from one format to others. Cost-efficient & effective GIS data conversion services are always in demand to convert different GIS datasets from one format to another to avoid their recreation.

GIS data conversion services generally encodes geographical format in each file. With increasing use of geographical content into different sectors like telecom, electric utilities, retail, oil & gas, real estate, banking, insurance, GIS data conversion outsourcing is the best choice of converting the hard copy into digital formats and maximise the benefits of available data.

With a team of highly qualified data engineers, we offer data conversion outsourcing where raster images are transformed to vector formats and vice versa without losing the data quality and veracity. The data conversion services offered by us takes care of the compatibility and interoperability between formats which generally creates big issues while moving data between various applications.

Outsource your GIS data conversion into our reliable hands and we will ensure seamless data conversion across various formats that are compatible to any software application and solution.

Transform data from its current format into a digital format

Existed One is Fine
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 GIS is the digital representation of an image. GISC 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. Conversion of data from one digital format to a new digital format is referred to as data translation. GISC’s team of experienced and multi-skilled specialists has a vast knowledge of converting various types of geospatial data.

DEM / DTM

Digital Elevation Model (DEM) is fundamental spatial data useful for carrying out several geospatial surveys. The elevation information made available through the DEM is key for cadastral surveys, infrastructure surveys, hydrological and environmental modelling.

A DEM can be generated from stereo aerial images and very high-resolution stereo images from satellites using photogrammetric techniques. DEM is also generated from SAR (Synthetic Aperture RADAR) images and from LiDAR point cloud. The resolution and accuracy of DEM generated through each of the above techniques and procedures is varied.

DEM from SAR may not be very high resolution and therefore have limited usage. DEM generation from LiDAR point cloud also has its own considerations while generating DEM for vast expanses.

DEM generation from stereo imagery is one of the reliable methods to create seamless surface models of varied terrains. Further the availability of very high-resolution stereo images covers the entire earth surface through its constant and continuous coverage.

The seamless and continued availability of DEM from stereo imagery over large expanses gives it an advantage over the DEM generated from aerial photographs and aerial LiDAR point clouds.

The DEM prepared through stereo imageries have very high vertical as well as horizontal accuracies and are fundamental to watershed and hydrological modelling. DEM from stereo imagery has applications in Civil Engineering and Construction works, RF Modelling in Wireless Communications, Training & Simulation in Military, Aviation, and Urban Planning, Topographic Mapping etc.

DEM from stereo imagery also have extensive applications in flood modelling and flood forecasting. The elevation model with utmost accuracy and precision derived from stereo imagery is critical to flood modelling especially in low lying areas where water accumulation is most.

Creating data in three dimensions

DEM DTM

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, GIS Consortium has created Digital Terrain Models (DTM), Digital Elevation Models (DEM) and Triangulated Irregular Network (TIN) for different domestic and international clients.

Geo-referencing

Satellite images and aerial photographs provides regular coverage of earth’s surface, but these are just like any other images or photos without having a geographic reference. Georeferencing of aerial imagery and georeferencing of satellite imagery build the geographic reference within the images. It actually relates the internal coordinate system of thesatellite image or aerial photo to a well-defined geographic coordinate system.

Georeferencing of aerial imagery as well as satellite imagery is fundamental for deriving meaningful information from the aerial and satellite images. The location reference that is built-in after georeferencing is key to all the spatial analytics that provides insights into the ever-changing dynamic activities that happens on earth surface.

The general process flow for georeferencing of aerial imagery and georeferencing of satellite imagery remains the same with few specific requirements of both aerial as well as satellite image georectification process.

Establishing the Ground Control Point (GCP) Network System is a very important part used in the process of georeferencing in aerial images as well as satellite images. It is also important for generation of 3D city models derived from stereo images.

The GCP Network (GCN) for georeferencing of aerial imagery requires more no of GCP’s compared to georeferencing of satellite images considering that the ground sampling resolution of aerial images is of very high. The ground sampling resolution of aerial images can go up to 2-3 cm while satellite images highest resolution till date is 30 cm.

With survey professionals equipped with knowledge and grounds-up understanding of setting up reliable GCN in the field, georeferencing of aerial as well as satellite images is one of our major forte since last 18 years.

Starting from deciding the optimal mix of primary, secondary, and tertiary points required for each project to setting up the desired GCN, georeferenced products from our company measures up to the international quality benchmarks and accuracy.

 

 
 
 

 

Our in-house multi-tier quality assurance and quality control system ensures that the georeferenced aerial and satellite image products satisfy the project needs and accuracy requirements.

The level of accuracy desired in georeferencing of aerial imagery and georeferencing of satellite imagery is different and our team is proficient in producing high quality accurate georeferenced aerial as well as satellite images.

Having delivered georeferenced aerial imagery and satellite imagery products to major national projects in India and abroad, our products catered to land management agencies, municipal authorities, utility companies. The requirement of highly accurate and precise georeferenced products for all these above sectors vouches for our quality products and their timely delivery.
