Earth Spatial SERVICES (ESS) has an experienced Photogrammetry team equipped with their latest digital Photogrammetry systems. We offer leading edge, professional mapping services which are time and cost effective. ESS offer comprehensive services in the field of Digital Photogrammetry to create 3D Data sets. Our offering includes:

 Aerial Triangulation

We are capable of triangulating large quantity of Aerial Images, UAV Images & Satellite scenes, Capable of triangulating the Images captured from latest digital cameras and sensors.

We ensure the high geometric stability of the blocks with well-defined external orientation and additional parameters meeting the RMSE within tolerance.

Digital Elevation Model (DEM)

We use advanced autocorrelation methods to extract high accurate Digital Elevation Model (DEM).

This allows us to derive a 3D model very quickly and affordably, providing maximum exploitation of imagery captured with digital aerial sensors while providing a basis for Orthophotography, Terrain Modeling, Planimetric Mapping and much more.

 Digital Surface Model (DSM)

A Digital Surface Model (DSM) is a 3D representation of the Earth's surface, including natural and man-made objects, like buildings and vegetation. It captures the heights of the surface, making it useful for various applications, including urban planning, disaster management, and 3D modeling. 

Planimetric Mapping

We are capable of capturing Planimetric data from Aerial Photographs and Satellite Stereo images.

We are specialized in Large Scale Mapping were the Planimetric details are captured from High Resolution Aerial Photographs with high accuracy generating precision 1-foot contour. Details like, Transportation, Buildings, Structures, Hydrography, Vegetation, Boundaries, Utilities, etc. are captured for comprehensive GIS solutions or for individual projects. Our techniques and detailed project management assure accurate results and consistent deliverables.

Terrain Modelling

We are involved in the development and deployment of Terrain models toi support 3D analysis. Surfaces derived from LiDAR, photogrammetric Techniques and auto correlated surfaces; provide a framework for which a "skin" of realistic imagery is applied, creating lifelike 3D scene.

Topographic Mapping

Earth Spatial SERVICES (ESS) PL compilers develop topographic data in a softcopy environment. This workflow is designed such that edge-matching data results in a seamless project wide topographic representation. Great care is taken to ensure accurate and timely deliverables.

Orthophoto Production

We are capable of processing Aerial Images Ortho-rectified images. We are also capable of processing satellite images of different sensors.

We do radiometric correction, atmospheric correction, Image fusion (resolution merge), histogram matching (tonal balancing), geo-referencing, ortho rectification, ortho mosaic, color balancing and cut the data into manageable small size tiles for better fill.

We are capable of producing True Orthophoto. An Orthophoto is "correct" at the terrain level were as a True Ortho photo is geometrically correct over in the entire image.

3D City Modeling

We have extensive knowledge in preparing 3D city models with real world texture from Multiple Data sources (True Ortho Photographs, UAV, High oblique Aerial Imagery, etc.) by implementing state of data quality combined with a considerable reduction of costs. ESS has the ability to create and maintain city wide 3D models for online and offline visualization.
