overview
Overview
  • Some GIS basics
  • How the database can be accessed
  • Submitting data
what is gis
What is GIS?

GIS = Geographic Information System

  • System for management, analysis, modeling, and visualization of geospatial data.
  • Integrates diverse data and models in a map-based context.

facilities

transport

topography

geology

wells

what is at or near location x
What is AT or NEAR Location X?

Location X

GIS FacilitatesData Integration

Wetlands

Geology

  • Location can be used as the central organizing principle for data from multiple databases-Questions can be asked of the data in 2 ways:1)What is at location X?2)At what locations does somecondition exist?

Utilities

Streets

Population

Property Boundaries

Pipelines

Streams

Counties

Point Sources

Slope or Aspect

Aerial Imagery

how a gis database works
How a GIS Database Works
  • Items in a traditional database are linked to a geographic representation of their real world location in the form of:
  • - points
  • - lines
  • - polygons
  • - grid cells

Vector Data

Raster Data

what is at or near location x6
What is AT or NEAR Location X?

Accessing the Database

agrc.utah.gov

servers

Shapefiles/GDBs

File based download

Oracle/SDE

Spatial Data

Direct database connection with ArcGIS

Tabular Data

Oracle client, Access, Excel

Internet Map Server

arcims prototype site
ArcIMS Prototype Site

Some basic exploratory analysis tools are included on the ArcIMS site.

  • The user needs only a moderately fast internet connection.

connecting directly to the sde database
Connecting Directly to the SDE Database

Those users with ArcGIS 9.0 can connect directly to the database and work with the data layers directly(read only)

Contact Barry Biediger [email protected] for the connection parameters and details.

file download
File Download

If there is enough need, an ftp site can be set up where users can download the GIS data layers in Geodatabase or Shapefile formats.

Alternatively, AGRC can send data layers to users as they request them.

submitting data to the database
Submitting data to the database
  • Any common GIS format can be submitted
      • Shapefiles
      • Geodatabases
      • Coverages
      • Any other format readable by ArcGIS
  • Flat files (e.g. Excel spreadsheets) with coordinates for point features.
metadata data describing data
Metadata (Data Describing Data)
  • Metadata is crucial for the credibility and understandability of the data.
  • At a minimum, these items need to be provided to AGRC when submitting data:
    • Description
    • Source
    • Scale
    • Definition of attributes
  • Projection information is absolutely necessary.
