Gis technology

Maps are everywhere—on the Internet, in our car, and even on our mobile phone. Moreover, maps of the twenty-first century are not just paper diagrams folded like an accordion. Maps today are colorful, searchable, interactive, and shared. This transformation of the static map into dynamic and interactive multimedia reflects the integration of technological innovation and vast amounts of geographic data. The key technology behind this integration, and subsequently the maps of the twenty-first century, is geographic information systems or GIS.

13. Information is Organized into layers

14. By combining layers and using operators and displays, GIS enables us to work with these layers to explore questions and find answers.

15. APPLICATION OF GIS

16. CRIME MAPPING Every crime problem is related to some location, whether it’s an address, street, ZIP Code, or district. GIS can help you leverage the locational aspect of your data to analyze, understand, and build solutions to the problems you face .

17. With the help of GIS we can understand the risks, develop proactive adaptation strategies, and increase society’s long-term resilience to climate change through policy modification . CLIMATE CHANGE

18. EMERGENCY MANAGEMENT GIS can help you with all phases of emergency management, from developing mitigation plans to managing limited resources in the midst of chaos and prioritizing recovery efforts once the dust settles.

19. HELPING ENGINEERS GIS technology provides a central location to conduct spatial analysis, overlay data, and integrate other solutions and systems. Built on a database rather than individual project files, GIS enables engineers to easily manage, reuse, share, and analyze data, saving time and resources.
