5. A GIS provides the Representation, Storage, Display and Visualization, Query, and Analysis of spatial and non-spatial data.
GIS applications serve a role in all industries.
GIS applications can be built by Subject Matter Experts and used by people at all skill levels.
What is GIS ?
Geographic – The “Where” or Location.
Information – The “What” or Description.
System – The things that make it work!

6. Geographic – The “Where” or Location
Spatial Data is stored in various formats through a variety of methods.
Raster –Continuous Data,
Pixels, Cells or Grids
Elevation, Weather
jpg, .sid, .tif,
Vector – Discreet Data
Points, Lines, Polygons
Survey Marker, Roads, Parcels !
Shapefiles, Geodatabases

7. Information – The “What” or … Description
Information – or Attribute data is stored with the GIS Data as part of the spatial features.
Attribute data – Data directly part of a spatial dataset.
Text Data
Numeric Data
Dates
Database, or Tables – Data separate from spatial data, but relatable to a spatial dataset.

8. System – The things that make it work!
People!
the Public, Mappers, Assessors, Realtors, GIS Analysts, Appraisers,
Workflow
Methods used to collect, process, use and distribute data
Hardware
Computers, GPS, Networks, Printers, etc…
Software
ArcGIS ArcMap, AutoCAD Map, Q-GIS, etc…
Data
Parcel Data, Reference Data, Cloud Services Data, etc…

9. Representation:
Real world phenomena into a digital environment. The ability to describe the real world object or place both by location and space and its descriptive, quantitative and qualitative features.

10. Data Stores
A GIS provides a structure for data storage. Data quality and validation tools enable a high level of confidence and integrity in data maintenance.
Additional tools provide for historical analysis at the parcel level.
Various data formats:
Shapefiles
Geodatabase
Enterprise Geodatabase

11. Query
Attribute
Spatial

12. Display and Visualization
On – Screen
Local
Kiosks
Internet Based
Interactive
Passive
Printed!
Custom / Single Maps
Automated Map Books

21. Parcel Fabric ESRI Geodatabase Featuredataset
Advanced Functionality and Tools for editing, storage and history.

22. Parcel Fabric A parcel fabric is made up of these elements:
Parcel lines, which have different categories and store COGO dimensions
Parcel points, which store x,y,z coordinates that can be adjusted in a fabric adjustment
Parcel polygons, which store area, parcel identification information, and are defined by parcel lines
Line points, which constrain parcel points to lie on the boundaries of adjacent parcels
Control points, which are used in a fabric adjustment and have accurate coordinates for a physical location
Plans (table), which store information about the record of survey
Parcel fabric jobs (table), which track edits to the parcel fabric
Accuracies (table), which store weights that are used on parcels and lines a fabric adjustment
Adjustment vectors (table), which store sets of displacement vectors from fabric adjustments
