GIS Software AnIn-house development By, Bhugol GIS Pvt Ltd For, RuTag- IITB
Motivation • Large number of government organizations / NGOs / Academic Institutions • Minimal penetration of GIS at operational level • Imported software too expensive, lacking support, and time consuming for manpower training • Government of India sponsored development of in-house GIS development
An Indigenous GIS tool for windows • GRAM++ (Geo Referenced Area Management) – A GIS tool • GRAM++ built with Object Oriented Approach • Works for both Vector and Raster data formats • A Windows Software Product
Modular Architecture • Data preparation • Vector Data Analysis • Raster Data Analysis • Map Visualization
List of Modules of GRAM++ Data Preparation • Input Output: The Input/Output module gives the facility to import/Export data with other formats from/into GRAM++ Vector and Raster format. • Map Edit: This module provides facility for digitization / vectorisation of map on the screen along with Projection selection and convertion
Input/Output Module – Data imported from Survey of India DVD format
List of Modules Contd... Vector Data Analysis • Vector Analysis: The Vector Analysis module gives the facility to query the map, generate various thematic and statistical maps • TIN: The GRAM++-TIN module allows to triangulate GRAM++ Vector point format data. It can also generate contours from Triangulated data. • GRAMNet: GRAMNet module, basically is a Network Analysis module. It has functionalities of finding shortest distance between a source node and the destination node, solve Location Allocation problem. • Statistics: The statistical module help the interpretation of the data information collected. The data / information may be spatial or non spatial.
Terrain – TIN Module Input Vertices TIN Interpolated Contours
List of Modules Contd... Raster Data Analysis • Raster Analysis: The Raster Analysis module has functions of arithmetic operations(like addition, subtraction etc), regrouping (class and range), Buffering, Zonal , Focal, Watershed Delineation etc. • Terrain: The Terrain module provides facility for generation of DTM from contour map and calculation of slope, aspect and generates • Image Processing: Image processing has functions to perform the operations such as Image Enhancement, Image Classification, and Image Transformation.
Watershed Tables Watershed Parameters Pour-points and stream order Flow
Terrain - Interpolation Contours Interpolated DTM
List of Modules Contd... Visualizer • Vector Layout: This module provides facility for visualising vector maps in 2D and 3D with the various layout features such as North arrow, Scale bar, Legends. • Raster Layout: This module provides facility for visualising raster maps in 2Dand 3D.It also provides several other integrated raster utilities such as North arrow. Online Help • Online Help: Keeping in view the types of users GRAM++, a detailed online help is provided for each function

GRAM++ GIS - Present status • GRAM++ GIS is presently being distributed, maintained and upgraded by an IIT incubatee BHUGOL GIS Pvt Ltd. via technology transfer • Within a short span of distribution GRAM++ has a rich user base in all the sectors (Educational/Government/NGO’s/Commercial) across India • Based on today's need and on the basis of GRAM++ Bhugol GIS has developed a web based GIS server software named WebGRAMServer (www.webgramserver.com)
Functionalities of WebGRAMServer (WGS) • WGS enable organizations to publish and share geographic data, maps, and • analyses over web • Web Gram Server is a server-based geographic information system (GIS) • It comes with web based services for spatial data management, • visualization, and spatial analysis along with publishing the maps over the web
List of Functionalities of WGS • Publish various map layers over the Web • Multiple layer view • Change the layer color, style and thickness for Point, Segment and Polygon type layers • Zoom in/Zoom Out/Fit to window • Panning • Info tool • Non-Spatial query and spatial query using one or data from multiple layers. • Thematic Mapping with single field • Thematic Mapping with two field • Class based/Range based classification
List of Functionalities of WGS • Dot Density based classification • Symbol based classification • Comparison the fields using Pie Chart representation • Database display • Highlighting feature from selected record • Applying transparency to the layer
GRAM++ GIS based Customized products • Data Preparation Tool • Spatial Database Creation • Raster Analysis Kit • Spatial Analysis in Raster Model • GRAM++ Toolkit • Set of reusable ActiveX Components • GRAM++ VecViewer • Standalone tool for map Query and Display • GRAM++ SDSS for RD • Tool on Spatial decision support for Rural Development • GIS Tutor • GIS tutor for learning and Teaching GIS
