General Questions

Phil Worrall, IGIC Executive Director

Question 1: Are there resources (white papers, tech support, etc.) for participating counties to help them stand up WFS for in-house ArcGIS Server implementation and testing?
Question 2: Is there a set schema for points and lines for statewide CAD (computer aided drafting)?
Question 3: Any thoughts to having a public map library online for publishing updates?
Question 4: How can we configure to publish the collection of section corner data around the state?
Question 5: How/where can I find water hydrant features? My county has some pretty good sources, but I believe it’s lacking these.
Question 6: Are data sharing grant counties using COTS or open-source software for their WFS services and/or new websites?
Question 7: I would like to know more about open-source GIS software. In tough economic times it’s virtually impossible to add more services. The problem I’ve seen with open-source is interoperability.
Question 8: How do you get your local departments to use the GIS data you have in place now?
Question 9: It would be helpful if we had a compilation of data acquisition standards, RFP examples, or a guidance group to assist local folks to acquire data. That would help us get the most for our money when acquiring new data and promote data standardization.
Question 10: Is IGIC assisting the state with a standardized way of attributing addresses?
Question 11: What grants if any are out there for local (city) government to help support their GIS departments?

Answers

Question 1: Are there resources (white papers, tech support, etc.) for participating counties to help them stand up WFS for in-house ArcGIS Server implementation and testing?

A: Yes. See www.igic.org/projects/indianamap/ArcGIS_Server_WFS_Service.pdf.


Question 2: Is there a set schema for points and lines for statewide CAD (computer aided drafting)?

A: The IGIC’s CAD-GIS Workgroup is developing a standard for data translation between the two formats. The current specifications can be found at: http://www.igic.org/igicwp/igic-indianamap-workgroups/indianamap-cad-gis-integration-workgroup-retired/.


Question 3: Any thoughts to having a public map library online for publishing updates?

A: We currently provide links to both dynamic and static maps available on the internet at www.igic.org/maps/index.html and www.indianamap.org/maps. We try to keep these links up to date, so if you know of additional sites or resources to add, please email info@igic.org.


Question 4: How can we configure to publish the collection of section corner data around the state?

A: IGIC and ISPLS (Indiana Society of Professional Land Surveyors) have jointly developed a Tie Card Program to allow County Surveyors to scan and digitize their section corner information onto the IndianaMap. The Tie Card methodology, resources and training video are available at no cost. For more information visit our Tie Card Project web site http://www.igic.org/igicwp/igic/projects/tie-card-scanning-project/. An example of tie card data published on the IndianaMap for Bartholomew County, IN can be seen by clicking visiting http://bit.ly/C5KON.


Question 5: How/where can I find water hydrant features? My county has some pretty good sources, but I believe it’s lacking these.

A: Fire hydrants are not available on the IndianaMap. You can check the GIS Inventory (Ramona) http://in.gisinventory.net to see if hydrant data is available in your county. Alternatively, the individual city, regional, or private water utilities serving your county, or local fire departments should have maps of hydrant locations, though these may not be in digital format.


Question 6: Are data sharing grant counties using COTS or open-source software for their WFS services and/or new websites?

A: Different counties use COTS software like ArcGIS Server, or open-source software like MapServer to stand-up their WFS services. These services can be stood up in conjunction with a web-mapping viewing application, but a web-mapping site is not a requirement for WFS. A number of counties rely on their GIS service provider (e.g., WTH, Sidwell, 39-Degrees North, The Schneider Corporation, etc.) to set up and host their WFS services.


Question 7: I would like to know more about open-source GIS software. In tough economic times it’s virtually impossible to add more services. The problem I’ve seen with open-source is interoperability.

A: There are a number of open-source packages like GRASS and MapServer, as well as free GIS viewing software like AccuGlobe and ArcExplorer. IGIC provide links to these products at http://www.igic.org/igicwp/resources/links/, but would also recommend you simply Google FREE GIS Software or Open-source GIS Software. Wikipedia also maintains a good list of free http://en.wikipedia.org/wiki/Category:Free_GIS_software and Open Source http://en.wikipedia.org/wiki/List_of_GIS_software GIS software.


Question 8: How do you get your local departments to use the GIS data you have in place now?

A: By making your data as easy as possible to use and integrating it into their normal workflows and projects. Also, providing a training class on where and how to access and use the data can help. We would suggest meeting with each department to discuss their exact needs and prepare a plan, including follow-up and on-going support for each group.


Question 9: It would be helpful if we had a compilation of data acquisition standards, RFP examples, or a guidance group to assist local folks to acquire data. That would help us get the most for our money when acquiring new data and promote data standardization.

A: Access to a number GIS standards are available through the IGIC web site at http://www.igic.org/igicwp/resources/standards/. Specific Framework Data standards can be found on the home pages of IGIC’s various IndianaMap Workgroups http://www.igic.org/igicwp/igic/projects/indianamap-framework-data-plans/. For sample RFPs and other information, please email your specific request to the IGIC office at info@igic.org.


Question 10: Is IGIC assisting the State with a standardized way of attributing addresses?

A: Yes! As part of our 2007 Address Integration Project we developed a point address and road centerline schema for addressing. This template was then incorporated into our 2008 Data Sharing Initiative, and subsequently into the data model for all data being harvested to the IndianaMap.


Question 11: What grants if any are out there for local (city) government to help support their GIS departments?

A: See IGIC Seminar Presentation “Grants and Other Funding Sources for GIS” posted on the IGIC website at http://www.igic.org/igicwp/calendar-events/training/igic-seminars-webinars-road-shows/l or visit our funding pages.
