Document Details

• Document Title: SURVEYKSHAK 3.0
• Authors: Sub DC Sharma and Sachin Kumar
• Supervisor: Lt Col Suman Kumar Sarkar
• Date: February 8, 2018
• Document Type: Standard Operating Process
• Purpose: Customized under CAMS, Mil Svy

Introduction

• An open-source GIS software (SURVEYKSHAK) has been customized for Defense forces.
• The software is designed based on a newly designed Defence Spatial Data Model (SDMS) for Defense Series Maps.

Capabilities

• The software can open and display digital topographical data using Mil Coordinate system, DSM sheet numbering, datum (WGS-84), Projection System, Grid (LCC), and file format (shp)
• Displays digital data in cartographic symbols, as depicted on hard copy maps. (Unlike other software)
• Handles geo-referenced digital satellite imagery/scanned topo maps.
• Captures coordinates in latitude/longitude format.
• Enables adding, editing, and updating spatial data (points, lines, polygons) with attribute tables.
• Groups feature classes
• Creates new attribute tables.
• Links photographs to features.
• Performs simple queries (e.g., locate a bridge, show roads)
• Measures distances.
• Analyzes networks.
• Supports 3D capabilities.
• Performs buffer zone analysis.
• Determines the location of features based on distance from other features.

Input Data

• Digital map data in shapefile format (*.shp).
• Files for Symbology definition (*.qml).
• Parameters for projection zone (/*.prj file).
• Satellite imageries/ topo scanned map (Geotiff).
• GPS data (points) coordinates in text/CSV format.
• Digital Elevation Model (DEM) for 3D analysis.

Installation

• Copy the Surveykshak 3.0 folder to your computer.
• Install the prerequisites.
• Install the NetFrame software as required by your Operating System.
• Open Terra Explorer.
• Copy Terra Explorer license file to the correct folder.
• Create a desktop shortcut if required.
