SURVEY facilities with latest technologies by using GPS Technology are best processed
in HEADS Site
The instrument GPS (Global Positioning System) is based on Satellite technology.
If the Survey is done in Surveyors TM Coordinates the data and Survey base Plan
may be created in TM Coordinates, which are not applicable universally by any user,
for example Contractor. So the Drawing & Data available in TM Coordinates are to
be converted to UTM (Universal Transverse Marcator) Coordinates. Both the conversions
(Drawing & Data) are possible in HEADS range of products to make KML / KMZ files
which may be superimposed on Google Satellite images (Version 2010) to view the
existing Land use and Merits/Demerits of each alignment options.
It is simple in HEADS Site to transform the Surveyors coordinates into Global UTM
/ GPS Coordinates using in-built CAD engine, next the transformed drawing may be
opened for conversion to KML/KMZ file to open in Google Earth to plan for Site Layout,
Green Field alignments, Bypasses and Realignments as larger area with existing Land
use are visible. Even the Original Ground Elevations along with Easting & Northing
Coordinates are available from the satellite images without doing the topographic
survey at the field.
Digital Terrain Model, Triangulation & Contouring
The area may be identified by site reconnaissance survey and using Topographic maps
and satellite imageries. Elevation data may be downloaded from SRTM (Shuttle Radar
Topography Mission) and contours have been generated for the entire area under the
study. This enables the users to produce Plan, Profile, Cross Section Drawings and
BoQ of the design work without carrying out Topographical Survey at field.

SURVEY BASE PLAN or GROUND MODEL is prepared from the Ground Survey Text
data and by selecting drawing feature symbols from CAD Block library, the various
texts obtained from the surveyors are also placed correctly in the Base Plan drawing.
The drawing is made in CAD layered system and is compatible to AutoCAD and other
popular CAD softwares for any further editing/drafting. Contours and DTM, with Ground
sections are also produced as Reports and CAD drawings for Plan & Profile, Cross
sections. This saves the time significantly in preparation for the Detail Engineering
ROAD Projects are facilitated with Interactive Design by Built-in CAD Engine,
HEADS Pro/Site is the masterpiece for its various applications in road engineering
projects. It enables the engineers and professionals to produce the best in their
