  1. What is GIS?

  2. What is GIS? • Geographical Information Systems • Formally started in the 60’s, although probably manually before this • late 80’s and the 90’s GIS gained momentum • Decreased cost of computers • Increasingly user friendly software • Availability of spatial data • Improvement of complimentary technologies – remote sensing, GPS • Appearance of formalized GIS training

  3. What is GIS? • GIS is a very large and multidisciplinary field • An all encompassing definition of GIS is difficult to form. • To help us better what GIS is we need to break it down….

  4. The ‘G’ of GIS • Geographic(al) indicates that we are dealing with data that is spatial in nature • That is data that has a coordinate associated with it, usually geographic

  5. The ‘I’ of GIS • Identifies that we have some sort of data component involved • Spatial data – where things are • Attribute data – about what is there Hydrant_ID: A01245 Flow: 35m3/sec. Diameter: 2 In.

  6. The ‘S’ of GIS Users Software Knowledge GIS Data Computers • Implies there are multiple components linked to each other • To be successful all components must be in place

  7. Functions of GIS • GIS is used to… • Capture • Storage • Manipulation • Retrieval • Analysis • Display • This is only possible with trained people! • GIS is not… • GPS • Just map making • Software Spatial Data

  8. Using GIS in Manitoba

  9. City of Brandon • An ownership layer was developed with the boundaries for every parcel of land within the city limits. • This ownership layer is used for a number of practical applications, including: • Taxation assessment • Land use planning purposes • Building permit applications

  10. Manitoba Conservation • Aerial survey recorded GPS coordinates for deer, elk and moose sightings in the Spruce Woods area. • Locations then entered into a GIS to help analyze and organize migration patterns of large game found in the area.

  11. Manitoba Hydro • Providing a reliable electricity source is critical in the potentially frigid Manitoban environment • Manitoba Hydro uses GIS to help pinpoint causes of power failures and quickly restore service to their customers.

  12. Manitoba Water Conservation Districts • Throughout Manitoba water conservation districts are using GIS to better manage their watersheds, including: • Soil erosion models • Waterfowl capacities • Ground water models • Surface water run-off potential

  13. Manitoba Land Initiative • The Manitoba Land Initiative Web site is the source for geo-spatial information from the Government of Manitoba. • With the creation of this free website available to all, the field of GIS will only continue to grow in Manitoba http://web2.gov.mb.ca/mli
