The Survey Department of the Aerial Engineering Division of the Indiana Department of Transportation coordinates a network of Continuously Operating Reference Stations (CORS). Each CORS site provides Global Navigation Satellite System (GNSS - GPS and GLONASS) carrier phase and code range measurements in support of 3-dimensional positioning activities throughout the state of Indiana.

Each CORS site provides Global Navigation Satellite System (GNSS - GPS and GLONASS) carrier phase and code range measurements in support of 3-dimensional positioning activities throughout the state of Indiana.
Surveyors, GIS/LIS professionals, engineers, scientists, and others can apply CORS data to position points at which GNSS data have been collected. The CORS system enables positioning accuracies that approach a few centimeters relative to the National Spatial Reference System, both horizontally and vertically.
RINEX data in the form of navigation, observation and glonass files are available for each of our sites. The data may be browsed via our FTP site found at: ftp://ftp.incors.in.gov. Files are available for two months from the current date.
Providing a real-time kinematic (RTK) correction service over the internet, and RINEX files for post-processing . End-users don’t have to be a Leica user to enjoy the benefits of INDOT's GNSS. If your GPS or GNSS receiver can connect to the internet, INDOT can deliver the data you need. With this service offered by INDOT using Leica's GNSS Technologies you don't need to invest in an extra base station to get accurate positions. You don't need to setup a base station first, worry about its safety. Just start your GNSS rover and connect. A few seconds later you can survey with cm-accuracy
Currently the InCORS is providing Network RTK in RTCM (Real Time Correction Message) 2.3, and 3.1 in the MAX (R2K2 Full) and i-MAX (R2K2 LITE) formats via NTRIP (Networked Transport of RTCM via Internet) and TCP/IP, as well as CMR and CMR+ in the MAX (R2K2 Full) and i-MAX (R2K2 LITE) formats via NTRIP , and TCP/IP. The main difference between MAX and i-MAX is the processing is done at the ROVER for MAX and with i-MAX the processing is done at the servers.
In order to access these messages the user will need a wireless modem device that can access the wireless web. The modems come in all shapes and styles and through different wireless providers. INDOT does not recommend one provider over the other, the user must determine the coverage in his/her particular area to determine the best solution.
The users also need to complete the RTK users agreement which is available as a link on the INCORS website. Once the RTK users agreement is signed and returned to INDOT, INDOT will provide the IP address, port number, account username, and account password of the system to the user.

Porter County is in the process of updating their county comprehensive drainage plan that includes new aerial photography. The following link is to a recent article from the local Post-Tribune News on March 18, 2010 - http://www.post-trib.com/news/porter/2109062,pcdrain.article. This article provides an interesting perspective on the numerous communities in the county starting to think beyond outside their boundaries, and when it comes to drainage and planning - events do not stop at jurisdictional boundaries, and neither should their mapping of planning.

As part of our 2009 FGDC CAP Grant for ongoing support of the Data Sharing Initiative, Image Matters LLC has developed a new Web Feature Service (WFS) Summarizer tool for IGIC. The URL to access the application is: http://www.igic.org/wfs
Enter the URL for a Web Feature Service (WFS) in the search bar. Then click 'Summarize' to see information about that WFS including the operations the service supports, a list of all available features offered and their attributes. To view the summary in a separate window, click 'Summarize in New Window'.
You can use this tool with any valid OGC WFS URL. Depending on the WFS Service software used by the provider and what options they support, report results may vary. Here are a few URL examples to test. Just copy/paste them into the search bar, and click on the desired Summarize option.

In 2006, IGIC migrated our online GIS Inventory to the National States' Geographic Information Council (NSGIC) "Ramona" system. Ramona is a Nation-wide GIS inventory tool that provides robust functions like on-the-fly status maps, a searchable user directory, and automatic "basic metadata" creation. The URL to access Indiana's Ramona site is: http://in.gisinventory.net/
Indiana's GIS Inventory is a critical tool used to...
1.) Benchmark the statewide status of GIS
2.) Perform a gap analysis for framework data coverage across the state (by different variables: levels of activity, scale, etc.)
3.) Plan and develop business cases for the completion of framework data statewide.
In 2006-2007 there was a big push to have each data steward in communities across the state complete their profile in Ramona. Since that time, some communities have kept this inventory up to date, but unfortunately most have not! For example, the display below shows only 2 communities in the State of Indiana currently reporting they have oblique (e.g. Pictometry) imagery products, and we know there are more!

We are asking you to please take the 20 minutes it takes to log-in and update your slice of your communities geospatial data profile. Adding your COMPLETE, IN WORK and PLANNED projects will directly support our efforts to identify funding and partnership opportunities across Indiana. If you are new to Ramona, you can simply create a new account and begin adding/editing your profile.

Ubiquitous Web 2.0 mobile technology is allowing for additions, updates and corrections to GIS data layers to be Crowd Sourced. Should we believe data provided by "the crowd in the cloud?"
My answer today is - Maybe-yes and Maybe-no. What if 1 person sends me a correction, or what if 100 people send me the same correction?
GIS data/service providers like OpenStreetMap, Google, Microsoft, Tele Atlas, Garmin and others are building tools for their crowds [customers] to help them improve their products and services. At IGIC are also looking at crowd sourcing opportunities to help us maintain and improve the IndianaMap. Harnessing the power of a benevolent crowd may be the answer to help keep the cost of GIS data layer creation and maintenance under control.

I posted the original blog last week about the story Ron Shawgo wrote in the October 6, 2009 Fort Wayne Journal Gazette - Allen County Sits Out Statewide Digital Map (See below)
Yesterday, an editorial by Frank Gray was published to this original story. http://journalgazette.net/article/20091101/LOCAL0201/311019902
Obviously, this topic is generating some local interest. I feel it is important to point out a few things that may not be obvious from these two stories:
1. Allen County does provide free access to their GIS data on-line - http://www.acimap.us/website/allenco/DataViewer/viewer.php
Allen County currently provides access to digital maps, basic & advanced search queries, and property reports including taxroll, property record card, and zoning information. This is already a pretty good web site, but just a few days ago I saw a demo of a new Web 2.0 version of this site that is currently under development by Allen County's iMap group, and it is one of the most comprehensive and powerful web-mapping tools I've seen!
2. For the most part, Indiana's State Legislature has been silent on creating a statewide funding model to support initial data development and the ongoing maintenance of GIS. In 2007, legislation was passed to create the GIO office and to create a statewide mapping fund to support GIS across Indiana (IC 4-23-7.3 Chapter 7.3. Indiana GIS Mapping Standards), but no funds were ever budgeted, so to this date, Indiana's GIS bank account remains virtually empty.
As a result, it is up to individual State Agencies, and to Local City/Town/County Governments across Indiana to come up with their own creative funding models for GIS, and the current Allen County model is just one of them. What is ironic is that no one disputes the need and value of local authoritative geospatial data to support good government at all levels (local, state and federal) . But to date, no one at the State level has stepped up to legislate funding for this important information infrastructure. IGIC's Legislative Committee is actively working on trying to solve this problem through education and outreach to advocate legislated funding for Indiana's GIS - http://igic.org/committees/leg.html.

This news story is much more positive than the headline may suggests. The opportunity for political change improves as the importance of sharing local geospatial information to benefit their constituents is more clearly understood by our elected officials!
