Digital Mapping of Defence Housing Authority (DHA) phases 1 to 7
This included digitization of layout plans on scale 1" = 200' (or 1:2400) covering phase I to phase VII. It included plots, road network, sewerage and manhole system, water pipeline system and all other features included and displayed in the map
Development of Geographic Information System (GIS) of services for phase VII
This includes the development of Geographic Information System (GIS) for all engineering services of Phase VII, services included were, water pipelines, sewerage lines & manholes, road network and plots. GIS was developed using the ArcInfo software and attributed through ArcView software for database management.
Transfer of technology to DHA designated staff, ECIL assignment included recommendation for relevant hardware & software and hand-on training to designated staff of DHA.
ECIL provided the following services to the client:
Production of digital maps of phases I to VII. From the existing map layout on scale 1:2400
Development of GIS for water lines, sewer lines, manholes, plots and road network of phase VII, using ArcInfo system
Physical verification (ground truthing) by GPS and fixing coordinates of landmarks
Recommendation of hardware and software for the implementation of GIS in Defence Housing Authority
Transfer of technology to DHA staff by imparting hands-on training
