GIS Data production & management


Governments and commercial photogrammetry/mapping agencies rely on Speck’s solutions to gather and analyze geospatial data. Speck provides the entire gamut of geospatial data production which includes effective capturing and exploitation of geospatial data to generate maps, terrain, models and orthophotos that is indispensable for data exploitation and other critical mapping applications.

Data Conversion and Engineering Service

Speck provides a complete range of data conversion services - starting with customized individual services that allow clients the flexibility of selecting specific tasks to end-to- end project management. Speck employs state- of- the-art tools and skilled professional manpower to deliver its quality services.

Speck’s data conversion and engineering services cater to a host of segments which include utility mapping, telecom, power, gas, water networks, topographical & cadastral mapping, natural resource mapping etc.

Leveraging its rich experience in this field of converting customer’s existing & legacy data, Speck can deliver output data in any CAD and GIS format including ArcInfo, DGN, DWG, DXF, SHP and/or client’s domain format. Speck has indegiously developed its own software which is competitive against International products, to convert analogue maps into digital format.

Some of our services in this area include:

  • Data scrubbing
  • Data conversion & maintenance
  • Data migration
  • Metadata creation
  • Data analysis & database design
  • Feature annotation and labeling
  • COGO based parcel mapping
  • Intelligent raster to vector conversion
  • Cartographic

Photogrammetry and Image Processing

Aerial Photography

Speck is the first private Indian company to be permitted by Directorate General of Civil Aviation(DGCA) for undertaking aerial photography. The company is in a strategic relationship with New Zealand Arial Mapping agency (NZAM) for aerial data acquisition.

Aerial Triangulation & Adjustment

Aerial triangulation is a critical component in the process of photogrammetric work flow. Speck’s team has the executed several projects involving photogrammetry deploying both conventional Analogue/Analytical AT and the state-of- the-art Digital equipment. PAT B, SocetSet ORIMA and Inpho are some of the software used by us to process data for Aerial Triangulation and bundle adjustment

Stereo Compilation (Planimetric and topographic)

Our team of photogrammetrists, facilitate creation of accurate and superior quality planimetric and topographic data, consistently, meeting stringent GIS specification. Speck carries out stereo compilation on both Analytical and Digital Photogrammetry equipment. With a track record of having  compiled maps with scale ranging from 1:500 to 1:100,000 and final delivery in digital format and REPMAT, Speck has the expertise to provide the full range of services in digital Photogrammetry –from creating basic planimetric features to complex 3D models
.
DTM Compilation, DEM and DSM Generation

Digital Terrain Models(DTM), Digital Elevation Models (DEMs) and Digital Surface Models (DSMs) are considered as comprehensive and efficient tools for studies using geo-referenced data and information. These are used in visualizing the terrain changes generally termed as Terrain Analysis. Such datasets are used to generate Digital Orthophoto (DOP) and are useful in contour generation.

Speck’s resources possess high level of expertise in generating both automatic and semi-automatic DEM's., with improved terrain accuracy. We adhere to the proper usage of hard and soft breaklines in all our DTM editing assignments, producing an accurate terrain representation, resulting in superior quality orthophotos.

Contour Mapping

A contour map is an illustration of lines (contour) joining points of equal elevation and depicting surface configurations. Speck has a experience in generation of manual contours and through DTM / DEM. 

Orthophoto Generation

Orthophotos commonly used in the creation and applications of GIS, measure true distances, as they have been adjusted for topographic relief,lens distortion, and camera tilt of the conventional aerial photographs.
Speck has the expertise and experience to generate rectified orthophotos using SocetSet, Inpho, VirtuoZo and PCI Geomatica. The ortho photos and/or ortho maps are merged together using OrthoVista, and seam lines created, and edited, to ensure a seamless mosaic and colour balance of the entire project area.
 
Light Detection and Ranging (LiDAR)

Light Detection and Ranging (LiDAR) systems generate accurate height data and intensity images which help to model the earth’s surface in detail.
Speck operates LiDAR systems, integrated with hyper-spectral sensors and digital Color / Multispectral cameras allowing the appropriate configuration to be used for a wide variety of projects. The sub-systems are designed to integrate varies components which ensures all data is collected in a digital format in a single machine.

Speck can offer unsurpassed response time and capacity. Whether the project requires economical “high and fast” or “low and slow” data acquisition for LiDAR projects, Speck’s diversity of platforms provides the correct solutions for acquisition and data fusion of all products.

Speck has executed several projects for Federal & Local Government, Telecommunication & Energy Providers, Transportation Authorities, Environmental & Agricultures, overseas and to several public or private sector industries.

We offer skilled LiDAR data processing, extracting accurate height models in the form of Digital Terrain Models (DTM) and Digital Surface Models (DSM). Our LiDAR services include

Other Services we offer:

  • Topographic Survey
  • 3D City and Urban Modeling
  • Feature Mapping by LiDARgrammetry
  • Corridor survey & Networking Inventory
  • Forestry Inventory
  • Disaster Management
  • Bathymetric Surveys
