Open access what does it mean
Open Access: What does it mean? Visualization

  • Geospatial data should be available for free for public use

  • It means this data could be shared with different government agencies, private and public sectors, and other countries.

  • It means there will be more and more data available for users. And more and more tools to support it


Old approach to data access
Old Approach to Data Access Visualization

  • Centralized processing of data into meta-data.

  • Often, data and data processing tools are proprietary…


Advantages of open access
Advantages of Open Access Visualization

  • Free of cost and free to re-use without any restriction

  • Open data lowers the cost of research and development

  • Promotes independent research

  • Facilitates the use and development of open standards and open source technologies


Free gis resources on the web
Free GIS resources on the web Visualization

  • Almost every state in the US provides web access to geospatial data

  • Many universities collaborate with state governments to provide more data and more tools

  • Map Window GIS is free and open source

    Affiliates include: Idoho State University, Utah State University,and National Oceanic &Atmospheric Administration…
