North Dakota Geospatial Web Services MAGIC Symposium April 25, 2006 Bob Nutsch GIS Coordinator State of North Dakota

Agenda Background & Overview Architecture Components Usage Lessons Learned Future Plans Summary Historic Camper Fryburg, Harley Jose

Background & Overview To increase efficiency and reduce overall GIS costs at the state level, the Legislature provided funding to build the North Dakota GIS Hub The GIS Hub is a database and web infrastructure used for hosting and sharing State agency GIS data and applications, it is located at the Information Technology Department General funds pay for data and application hosting, agencies pay for development costs

Background & Overview The primary purpose of the GIS Hub is to provide a central database serving state agencies Web services are used by agencies and their constituents, the public, consulting firms, and other levels of government Web services as used here is a general term for data discovery, data browsing, and data delivery

Architecture - Software ESRI – ArcIMS & ArcSDE Safe Software – FME and Spatial Direct Latitude Geographics – Geocortex Statistics IBM – HTTP web server & WebSphere Oracle Linux, Solaris, Windows

Architecture - Hardware

Components – Hub Explorer Template used for browser-based application development Used by state agencies for interactive mapping There are both internal and external Hub Explorer sites Includes ability to download vector data

Components – Hub Explorer

Hub Explorer – Game and Fish

Hub Explorer – Dept. of Ag.

Hub Explorer – Data Download

Hub Explorer – Data Download

Components – Metadata Explorer Data browsing and discovery Referenced data sets include: GIS Hub web image and feature services Raster data available on FTP In-progress datasets Interactive maps County data Includes vector data downloading Mined by Geospatial One-Stop

Metadata Explorer

Metadata Explorer

Metadata Explorer

Metadata Explorer – Download Data

Components – Utility Toolbox Runs as a servlet Contains general application utilities Used to record addresses that have failed geocoding Used to create agency “static” maps: NDDOT – road conditions, construction, load restrictions ND Emergency Services – rangeland fire index

Utility Toolbox – NDDOT Maps Road Conditions Road Construction Load Restrictions

Utility Toolbox – Fire Index

Components – Data Streaming ESRI-centric image and feature services Streaming of image and vector data Primarily used by users outside of firewall OGC-centric Web Map Services The first WMS was developed for use by the National Map Used by state and federal agencies Additional WMS are created as needed

Data Streaming - Feature & Image Services

Data Streaming - Feature & Image Services ArcMap

Data Streaming - Feature & Image Services ArcExplorer

Data Streaming - WMS The National Map

Data Streaming - WMS ND State Water Commission (MapServer)

Data Streaming - WMS Using uDig to display the Ft. Lincoln Infantry Post (Custer rode from Ft. Lincoln to Little Bighorn)

GIS Hub Web Services Usage 68,400 data downloads – 5.8 terabytes (3/2004-3/2006) Feature services – est. 15,000 hits Jan-Mar Web applications average 70,000+ hits/month 2006 WMS

Image Services - Usage October 5, 2005 Snowstorm

Image Services - Usage Popular Extents for the public-facing Game & Fish Hub Explorer - 2005

Lessons Learned Templates allow more rapid development of applications Multiple production servers – load balancing, maintenance, upgrades Test/development server, including access by agencies Use metadata as a method of web-based data discovery – helps agencies recognize the value in metadata

Lessons Learned Monitor usage of web services: Remove under utilized services, or combine into fewer services Recognize highly used and/or important services – optimize software and apply monitoring tools Consider creation of OGC web services if not yet available

Future Plans As demand requires: Develop additional WMS Implement WFS and other OGC services Migrate from ESRI-centric web services to OGC-centric web services Raster downloading via Hub Explorer and Metadata Explorer Improvements to Metadata Explorer including metadata submittal

Summary Geospatial web services are a mechanism for getting data out to users who would otherwise not have easy access to it It is important to Provide options for data discovery, data browsing and data delivery Provide a buffet of data delivery choices – streaming and download Geospatial web services assist in economic development – oil & gas, coal, hunting, fishing, business siting Web services can free up agency time
