Photogrammetry:

Using highly efficient technological apparatus we are able to meet the specifications of our clients with precision. Dale with a staff of professional technicians and Photogrammetric Experts deliver products and quality services with exceptional competence.

Our Photogrammetric Services:

  • Aerial Triangulation
  • Softcopy Stereo Compilation (Planimetric/Vector Feature Extraction)
  • Digital Elevation/Terrain Modeling
  • Map Editing.

Aerial Triangulation:

  • Automated and Manual Aerial Triangulation methods are available.
  • Manual Aerial Triangulation processing is preferred for its higher accuracy.
  • We provide the clients with detailed triangulation reports of results and error analysis.
  • A root mean square (RMS) error of less than [1/10,000 times flying height] is typical.

Planimetric 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:

  • All roadways including curb and gutter
  • All driveways paved and unpaved
  • All parking surfaces and paint markings
  • All structures
  • All vegetation including landscape shrubbery and trees
  • All hydrographic features including manholes, catch basins, valves etc.
  • All utilities such as power poles, light post, guy wire etc.

Typical features collected at 1”=100scale:

  • Roadways
  • Driveways
  • Parking Surfaces
  • Structures
  • Tree lines and landmark single trees
  • Major Hydrographic features
  • Major Utilities

Digital Elevation and Terrain Modeling (DEM/DTM):

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.

Map Editing:

Dale 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 Ortho Photography:

Using highly efficient technological apparatus we are able to meet the specifications of our clients with precision. Dale with a staff of professional technicians and Ortho Experts deliver products and quality services with exceptional competence.

Our Orthophoto Production services:
Ortho-mosaicing, Color Balancing, Seam line editing and Tile cutting.

Using computerized aerial/satellite imagery and making corrections through digital image processing for positioning of all ground features on the maps along the earth-referenced coordinate system, is called Digital ortho photography. Associated with CAD & GIS software systems, Digital ortho photography is a prominent tool in producing accurate measurements.

We use photo grammetric software on our High Powered Digital Workstations in performing Ortho rectification processes. We use adept image editing software for radiometric alterations and modifications in the images and finally present the output in many formats including TFW, MrSid, JPEG2000, ECW etc.

GIS
Using highly efficient technological apparatus we are able to meet the specifications of our clients with precision. Dale with a staff of professional technicians and GIS Experts deliver products and quality services with exceptional competence. Dale excels at providing innovative solutions for spatial data processing and GIS design. With the experience we gained from good projects that we have successfully delivered, we are able to design an adaptable technique that benefits the clients in several ways. This includes planning the project according to the clients specifications and data, analyzing the cost for executing the program of the project in all levels of production and for the software and hardware that will be used, providing regular feedback and detailed reports to the clients and also making the final data and internal architecture of GIS available to the clients.

Map Design and 3-D Modeling
We create 3-D images of high resolution with elevation data and TIN (Triangulated Irregular Networks) using the latest software and advanced rendering tools. The output images are very natural with shades from the elevations of terrains that are produced by the illumination of sun light. Applications include resource extraction, infrastructure planning, utility management and recreation usage.

Raster to Vector & Lease Plotting
Raster to Vector involves creating vectors to all the rail tracks, roads, plots, and others from the Raster images using the software tools like Raster design 2009 on Map, Autodesk Map 2009, OGINFO Map, Deed Plotter and ARCGIS. A DWG file contains roads, plots and creeks while the PDF file contains the details of Lease plots. Using these files we capture the lease plots appropriate to the clients. This is called Lease Plotting.

SURVEY
Dale Technologies provides a wide range of GIS Surveying services which includes the traditional and new surveying services. Some of the services are listed below.

  • Topographic Surveying
  • Cadastral Surveying
  • Construction layout Surveying
  • Hydrographic surveys/cross sections
  • Utility Surveys
  • Engineering Surveys
  • Geodetic control/height modernization

We have the latest and updated infrastructure for all our surveying services. For processing and analyzing the field data we use effective software tools. Dale’s professional and dedicated surveyors set up GPS based control stations after analyzing, designing and installing the survey monuments for land management. To make sure that there are no interruptions in the progress of the project, our surveyors will always be in acquaintance with the regulatory agencies, owners of the lands and any other parties that are involved. Our surveyors provide a precise post-plot survey which is very beneficial for the project.
