This document discusses geographic information systems (GIS) and global positioning systems (GPS). GIS puts important location-based information like states, roads, and city boundaries onto maps. GPS uses satellites to provide precise location coordinates, with most consumer GPS having an accuracy of around 10 meters. The document outlines how surveyors will use GPS-enabled devices and trackers to obtain multiple location readings for assets, which will then be averaged and mapped as a GIS layer to mark the fixed positions of sites on a map.

Global Positioning System is a network of orbiting satellites that send
precise details of their position in space back to earth.

11. The accuracy of a position determined with GPS
depends on the type of receiver. Most consumer GPS
units have an accuracy of about +/-10m.
We will provide GPS trackers too, with surveyors Gps
enabled mobile devices.
Whenever Surveyor reaches to the position of assets,
he will click on mobile device to fetch his current
location & also click a button on Gps tracker device. So
that two Lat/Long will be fetched in server .
After getting multiple Lat/Long, by using some
medium we retrieve average & more accurate position
of assets.

12.  Field Team would carry an GPS based handheld
devices (Rovers) for marking the GPS co-ordinates of
the identified Assets. The data on the handheld
devices is synchronized with the data server
immediately after saving.
 Site inspection form will be designed for the field-
team to fill whenever a piece of Field-Asset is located.

14.  Whenever the team is moving in the field,
their location is captured continuously. This
movement will be visible as a trace of the
PATH travelled on the web page of the
application. The admin will be able to ensure
that no area is left uncovered and there is
minimum wastage of team effort in traversing
the same path multiple times.

16. Once average
Lat/Longs
determined from the
values obtained from
Gps Tracker device,
the position of sites
will be marked fixed
on the map.
This marking of site
on map will be called
as GIS layer.
