We use remote sensing technology based on requirements range from utility planning, LULC, urban and rural infrastructure using high resolution satellite imagery to forest mapping, natural resource mapping, watershed management using low resolution satellite imagery etc., we apply spatial / spectral resolutions on various Satellite Imagery applications to provide services include data conversion, processing, interpretation and further analysis.
We are able to meet the Clients specifications with precision. Our Photogrammetric experts deliver products and quality services with exceptional competence to easily deliver Digital elevation models 2D/3D maps from UAV, Aerial and Satellite imagery data.
Our Photogrammetric Services Offered:
Aerial Triangulation represents the mathematical process of establishing precise and accurate relationships between the individual image coordinate systems and a defined datum and projection (ground).
The main objective of aerial triangulation is to produce from ground control, sufficient points in the photogrammetric models to ensure that each model can be oriented accurately as required for stereo compilation in either orthophoto or line mapping.
Planimetric/Topographic mapping is used in representing the features of the earth's surface in three dimensions (3-D). We use Line String, Line, Point/Symbol and Polygon/region data for this representation. Our experts collect Digital Topographic and Planimetric features interactively and most of these features are collected with a definite elevation, which in turn are used in the process of generating contour (a part of the Digital Terrain Modeling).
Typical features collected at 1"=50' scale:
Typical features collected at 1"=100'scale:
To show the accurate representation of surface features and elevations on the earth's surface we use DTM and DEM tools. We collect the DTM and DEM data sets according to the requirement of the clients. We use dominant tools in generating automatic and advanced contours. In DTM Models, to show accurate changes in elevation we use break lines and data points. These models define the surface in an irregular spacing pattern. DEM Models uses grid pattern to define the surface. This enables us to show the changes in elevation in a smooth and progressive sort. These are basically used in Ortho-Rectification process, Contours generation and also in GIS applications. Precise depiction of terrain is significant as it is very much useful for Volumetric and TIN calculations.
We delivers ingenious layout and design of the map sheet. With advanced contour interpolation, Processes like Cartographic editing, Planimetric data cleaning and its topological structuring and many are available.
Digital OrthoPhotography:
The orthorectification procedure is divided into different steps in the following images. Some of them are tightly connected and work in iterations (geometric modeling and gross error removal), whereas others are mostly independent (e.g., GCP extraction) and could work as stand-alone modules. The chain is completely automatic, and the start of the processing can be triggered by the appearance of an image in a specifically designated folder on the processing server. At the moment of arrival, the process first starts with the extraction of useful information from the metadata file. The procedure then continues with GCP extraction, geometric modeling, and, finally, orthorectification. The final results are orthoimages and a log file with information about the processing, parameter values, and achieved accuracies.
