GIS in Generals• GIS is a powerful set of tools for collecting,

storing, retrieving, transforming and displaying spatial data from real world for a particular set of purpose.

• GIS is a computer based system that is used to manipulate the spatial and non spatial data in digital form

• GIS is an organized collections of computer hardware, software, geographic data, and personnel designated to efficiently capture, store, update, manipulate, analyze and display all forms of geographically referenced information

• GPS is a system of satellites ground stations and receivers that allows us to find exact location of a place on Earth.

• One of the significant and unique features of the GPS is that the positioning signal is available to the users in any position at any time worldwide.

• Recent GPS receivers with more add-on and easy to use features make spatial data capturing process effective.

• GPS is an effective tool for GIS data capture and provides an alternate for field data collection.

How GPS works?



• Remote sensing is the science of acquiring information (spectral, spatial, temporal) about material objects, area, or phenomena through the analysis of data acquired by a device from measurements made at a distance, without coming into physical contact with the objects, area, or phenomena under investigation.

With an Example of District Transport Master Plan

(DTMP)


Objective

To Prepare the District Transport Master Plan (DTMP) based on the new guidelines 2012


STEPS• Step 1: District Orientation/Workshop I• Step 2: GPS survey for District Road Inventory• Step 3: District Road Inventory Mapping• Step 4: Identification of the District Road Core

Network (DRCN) • Step 5: Collection of primary and secondary data

for DRCN • Step 6: Finalization of DRCN/Workshop II• Step 7 : Preparation of the DTMP/DTPP• Step 8: DTMP Approval/ Workshop III 12/20/2014 Binod Dhakal 29
