  • Last year we spoke about the need for our GIS client to start using GIS to solve problems and I’m happy to announce that many of you have taken charge…………..
  • Schneider brings a combined GIS experience of over 300 years. Largest multi-discipline GIS, surveying, and civil engineering consulting firm in Indiana 20 Registered Indiana Land Surveyors & Civil Engineers Financial depth to do these types of projects ($22m firm) why is that important to them? Because it allows us to reinvest $600,000 into technology to provide better solutions for our clients All work done in the Indiana Trimble, Azteca, MicroData, GeoCom, AutoDesk, Microsoft, ESRI Alleviate “bleeding edge” for our clients Ensure practical implementation that avoid pitfalls and problems Insure compatibility with future software releases and long term goals Protect client investment
  • IUPPS compares an area boundary to determine who gets notified. Once HSE boundary changes they notify IUPPS and submit a new boundary file.
  • The e-mail is in a standard format
  • Shows three parts to e-mail request sent to SAMCO UL-Point file in text format. LR – Jpeg image and middle is e-mail.
  • Shows Attributes transferred from e-mail into geodatabase. Email Distribution Emergency Status A location request with an emergency status will send a notification to responsible personnel via pager or cellular telephone Locates around perimeter of HSE boundaries Fall under a “may need to locate” rather than a “need to locate” category These will be sent to personnel for manual interpretation
  • During the process of staking out an existing utility Physical structure coordinate values are compared to the coordinate values in the GIS database Report is automatically generated if discrepancies are present Database can be updated if needed
  • Additional capabilities – GPS time stamp, location, duration and historical tracking
  • The Citizen Input Form was designed to facilitate input from Beech Grove citizens to City administrators and staff. This form allows anyone to report incidents like missing street signs or potholes and have that report routed directly to the appropriate City department. The form allows users to first select a point of interest on the map and then fill out the form with the appropriate information to be submitted. The following are step by step instructions for submitting citizen input: Select the Citizen Input layer. (If the Citizen Input layer is not already selected.) Select the map tab to switch to the map view.  (Located on the tab bar immediately below the page header.) Zoom to the location of interest using the map navigation tools. Select the location tool by clicking on the icon. (The tool's background will change to indicate it has been selected.) Click a point on the map to indicate area of interest. (The application will then redirect the user to the input form.) Fill out the form with the appropriate data. Press the submit button. (You will recieve confirmation that your submission was successful.)  
  • With our with out your help. Then provide to insurance providers
  • City has and overall rating of a “6” want to be a “5” (WHAT IS THIS WORTH)
  • The traditional method is little better than throwing a dart at a map.  That’s pretty much how they picked the locations of the future fire stations in the maps below, but the software can also help find more suitable locations.  In fact, you could probably throw that into the Return on Investment section.
  • The roads that are not included in the trial can be modeled for drive time based on the posted speed limit and the segment length.  Adjustments can and should be made to account for the acceleration/deceleration time associated with turns and negotiating traffic at intersections. The ArcGIS Network Analyst Extension uses these drive times as input to produce a drive time model for the entire centerline dataset.  In the graphic below, the impedance is set to Drivetime (Seconds).  This tells the software that traveling along a road segment has a “cost”, or the time it takes to travel the segment.  We can also set restrictions to movement along segments such as Oneway restrictions or road closures.
  • Once the road network is built, you can perform 4 basic types of analysis: Service Area, Route, Closest Facility, and OD Cost Matrix.  The only one we really didn’t use for Fishers is the Route Analysis.
  • The decision is still up in the air, but the Chief is pushing for the 3 station solution as well as an additional single-engine station in the northwest to cover that area more effectively. Route This is basically used for route planning to multiple destinations (such as in package delivery).  Since fire response doesn’t really work that way, we didn’t utilize Route Analysis. Closest Facility In terms of fire response analysis, this set of tools allows the user to assess the nature and time of response on a per incident basis.  You can use real or hypothetical incidents and facilities to determine which facilities can best respond.  This is great for on-the-fly demonstrations of how changes in the number and placement of fire stations can affect fire response (to individual commissioners’ houses, even).  Below is an example from Fishers.  The purple box is a hypothetical fire incident.  We told the tool to show the three closest facilities, the routes they would take to get to the incident, and how long it would take for them to arrive once they left the facility.
  • OD Cost Matrix The “OD” stands for “Origin-Destination.”  It works much like the Closest Facility tools, but can handle multiple incidents and does not provide routing.  It does, however, provide drive times from each facility (yellow) to each incident (magenta…or is that fuscia?).  This tool can be used to help place fire stations based on collective response times to multiple incidents.
  • some maps to depict the suitability of areas in the eastern part of town based on drive time.  They were also considering a redraw of their station service zones based on the 5 minute drive time boundaries, but the analysis produced polygons that matched so closely with their existing zones that they decided not to J.  Currently working on modeling drive times for a couple of other stations in Marion Co just south of Fishers.  The folks in Geist who are resisting annexation are arguing that the two Lawrence Twp stations will largely cover them.  Based on what I’m seeing, they’re not.
  • City placed sidewalks on the home owners
  • About 1 gb pix’s collected 5,683 images
  • Sidewalk Inventory Purpose City wide inventory of all sidewalks and missing sidewalks and their condition. Photos were taken of damaged areas Reports showing costs were generated along with a maps indicating damaged areas. Problem Community was being sued to fix and build ADA compliant sidewalks throughout the entire community Community indicated that they did not have the funding to make all the corrections to the sidewalk They have a statute or ordinance in place that supposedly the home owner is responsible for the sidewalk Estimated cost of repairs and new improvements over $11 million dollars How? Ortho review of existing sidewalks Added data layers to GPS units with forms TrimPix added to GPS unit and Camera is connection Field collection GPS points collected of damaged areas Attributes describing condition were entered Photos were taken and linked to the GPS point Return on Investment The City now has a clear view of their sidewalk problems They are able to budget and prioritize areas based on condition ratings
