GIS is a computer system for capturing, storing, analyzing and displaying geographic information. It allows users to integrate digital maps, aerial photos, satellite images and GPS data. The presentation introduces GIS components, data models, how GIS works in a 5 step process, and examples of GIS applications for 3D city modeling, traffic simulation, watershed delineation and political analysis. It also discusses the ArcGIS software suite, including ArcMap for mapping, ArcCatalog for data management and ArcToolbox for geoprocessing tools.
Introduction to GIS and its Applications
- 1. Presented By : Uttam Pudasaini www.naxa.com.np Introduction to Geographic Information System(GIS) DAY 1
- 3. Software GIS ….. (misconceptions)??? A Map making tool Similar to CAD Elixir
- 4. GIS (Geographic Information System) A computer-based system that can be used to capture, store, query, analyze, display and output geographic information. GIS makes it possible to integrate different kinds of geographic information : Digital maps, Aerial photographs, Satellite Images and Global positioning system (GPS) data along with associated tabular database information/Attributes
- 5. Components GIS involves complete understanding about Patterns, Space, and Processes or Methodology needed to approach a problem. Links locational and database information and enables a person to visualize patterns, relationship and trends.
- 6. GIS
- 7. Transforming real World Geographic Objects to Objects on Computer 1.Representation of Geographic Reality -Through the use of data models 2.Linking Attributes to geographic representation 3.Spatial relationship between geographic representations Vector and Raster Data Models
- 8. How GIS works? -5 step process by ESRI Ask What is the problem you are trying to solve or analyze, and where is it located? Acquire Find the data needed to complete your project. Examine Thorough examination of how the data is organized, how accurate it is and where the data came from. Analyse Geographic analysis is the core strength of GIS. Depending on your project, there are many different analysis methods. Act Share your results through reports, maps, tables, and charts and delivered in printed format or digitally over a network or on the web.
- 9. What can we do with GIS???
- 10. 3D Modelling of Cities People in thousands of organizations in many different industries use ArcGIS in a wide range of applications. 3D Model of KU: https://www.youtube.com/watch?v=yR_QqbpgLSM
- 11. Traffic Simulation using GIS Transforming GIS Data into Functional Road Models for Large-Scale Traffic Simulation
- 12. Watershed Delineation Volume Calculation of a Reservoir
- 13. GIS and Politics: Presidential election results
- 14. It provides a powerful medium for managing, visualizing, and communicating about our world.
- 15. Evolution of GIS has transformed and revolutionized the ways in which Planners, Engineers, Managers etc. conduct the management and analysis of geospatial data.
- 16. Course Content : naxa.com.np/what-we-do/#gis-training Training content_NAXA.PDF GIS TRAINING COURSE
- 17. For this training session: We will be using ArcGIS Desktop 10, later version of a popular GIS software produced by ESRI. This course is meant to teach some fundamental GIS operations using ArcGIS. It is not meant to be a comprehensive course in GIS or ArcGIS.
- 18. ArcGIS - By Environmental System Research Institute Inc., Redlands, CA (ESRI)'s A family of GIS products that forms a complete Geographic Information System (GIS) on industry standard. Four primary frameworks of GIS are: ArcGIS Desktop—Professional GIS applications composed of three main software products: ArcView, ArcEditor, and ArcInfo Developer GIS—Embeddable software components for developers to extend GIS applications Mobile GIS: ArcPad, and ArcGIS Mobile for field computing. Server GIS: ArcIMS, ArcGIS Server, and ArcGIS Image Server
- 19. ArcGIS Desktop is comprised of a set of integrated applications: • ArcMap , ArcCatalog and ArcToolbox. ArcMap Main mapping application which allows you to create maps, query attributes, analyze spatial relationships, and layout final projects.
- 20. ArcCatalog Organizes spatial data contained on your computer and various other locations and allows for you to Search, Preview, and Add data to ArcMap as well as manage Metadata.
- 21. Easily accessed and used within ArcMap and ArcCatalog. ArcToolbox contains tools for geoprocessing, data conversion, coordinate systems, projections and many more. ArcToolbox
- 22. “Give a man a fish and you feed him for a day; Teach a man to fish and you feed him for a lifetime.”
- 23. We hope this seminar will get you started using GIS and excited about learning more Learn more about GIS and its Applications: http://www.colorado.edu/geography/gcraft/notes/notes.html
