Tennessee Base Mapping Program

December 8, 2008

According to the TN Base Mapping Website, “the Tennessee Base Mapping Program seeks to develop a comprehensive spatial database that will dramatically move GIS in the State of Tennessee to the leading edge of the technology.”

The purpose of the Base Mapping Program is to produce a comprehensive digital base map suitable for inclusion in Geographic Information Systems (GIS). The base map consists of Digital Ortho Imagery and digital parcel database. An inherent component of the parcel database will be a link to the Comptroller’s Computer Aided Assessment System (CAAS). (From: TN BMP – FAQ)

Base Mapping Program Links:

Frequently Asked Questions
Technical Specifications (PDF Format)

It is my understanding, that in the next couple of years, TN will be migrating from CAAS to “Integrated Multi-Processing of Administrative and CAMA Technology” (IMPACT).


Spatial Data Servers

December 4, 2008

Much of the GIS work I have done has been focused in the South, primarily Kentucky and Tennessee.  As with most GIS Professionals, I spend time on each project data mining.  Here is a list of sites I have found useful:

TN

Welcome to the Tennessee GIS Spatial Data Server

Welcome to the Tennessee Federal GIS Data Server. Developed by the Tennessee Federal GIS Users Group and the supported by the Tennessee Geographic Information Council TNGIC, this server distributes spatial data layers that are shared among Federal, State, and local GIS facilities in Tennessee.

My Opinion:
Looks of data but in some cases the info is dated.

GIS Services

Welcome to the GISource website, GIS Services gateway to the Internet. This site will be a dynamic source for information about geospatial technologies in Tennessee state government.

My Opinion:
Very little data available for download, but does provide access to several web services.

KY

Kentucky: Commonwealth Office of Technology – Main Page

As part of the Commonwealth Office of Technology, the Division of Geographic Information DGI is responsible for encouraging, coordinating, and implementing geographic information systems GIS within the Commonwealth of Kentucky. The division works with state, federal, and local governments to further geospatial efforts through activities which include strategic planning, project management, technical and administrative support, dissemination of spatial data, education and training, research, and policy development.

My Opinion:

When I used to work in KY alot this was one of the best resources available.  There is lots of data for download and a good number of links to other sites

Kentucky Groundwater Data Repository

The Kentucky Groundwater Data Repository was initiated in 1990 by the Kentucky Geological Survey under mandate from the Kentucky legislature KRS 151:035. The repository was established to archive and disseminate groundwater data collected by State agencies, other organizations, and independent researchers.

The repository database currently contains information for over 56,000 water wells, 4,000 springs, 350 dye traces, and 45,000 water-quality analyses. Included in these data are general water-well information such as location, usage, total depth, and static water level; well-construction information; water-quality data such as major and minor ionic constituents, pesticides, metals, volatile organic compounds, isotopic analyses, trace-organic analyses, and bacterial analyses; spring data; discharge measurements; and groundwater dye-trace data.

My Opinion:

Good site for Groundwater data in KY

IL

Illinois Clearinghouse: Statewide GIS Data and Metadata

Access data sets and associated metadata listed:

  • Base Data
  • Base Data and PLSS Infrastructure
  • Infrastructure Elevation
  • Elevation Bedrock Geology
  • Bedrock Geology Surficial Geology
  • Surficial Geology Water Resources
  • Water Resources and Hydrology

My Opinion:

I only used this site to make a county index map for IL.  Seems like it might be a good resource.

AR

GeoStor – Arkansas’ Official GeoData Clearinghouse

Geostor is an on-line data delivery system that allows users seamless access to digital map data GIS Data in Arkansas.

Arkansas_State

The Natural State Digital Database (NSDD) was developed by the Spatial Analysis Laboratory to serve the GIS user community and the state of Arkansas. This web site is a reality because of the work of the SAL, along with other people in the state who feel there should be a site in Arkansas to obtain free base GIS data

MO

MSDIS Homepage

The Missouri Spatial Data Information Service provides public access to GIS and census data about the State of Missouri.

AL

GSA | OGB

OGB GIS Data – Shapefiles

My Opinion:

Does not seem to be much data on the site

GA

Georgia Spatial Data Infrastructure Home Page


Geospatial Data Gateway

November 22, 2008

The Geospatial Data Gateway is quite possible my most used free data resource.

From the Site:

The Geospatial Data Gateway provides One Stop Shopping for natural resources or environmental data at anytime, from anywhere, to anyone. The Gateway allows you to choose your area of interest, browse and select data from our catalog, customize the format, and have it downloaded or shipped on CD or DVD.

In particular the NAIP data is useful.  According to the metadata, I believe the goal is to make the imagery available within 90 days of flight.  If you plan on using the site, I have notice some issues:

  • There is a wait time to download.  User is notified via email.
  • Email Contains multiple links to download.  Each dataset ordered is a separate package
  • Some imagery is .jp2 format,  In ArcGIS band 4 should be turned off to make imagery clearer
