  • 1. Introduction

The City of Galesburg invites qualified vendors to submit proposals for the creation of digital aerial orthophotography for the City of Galesburg (the City). This imagery will be used in the City's Geographic Information System. 1.1 Community Profile The City of Galesburg is the county seat of Knox County, in the western part of Illinois (see Figure 1 of Appendix 1). The 2004 estimated population of Galesburg was 32,408; Knox County's estimated population was 53,884. 1.2 City of Galesburg GIS Background The City became actively involved in GIS development beginning in 1997 as a founding partner of the Knox County GIS Steering Committee. The Galesburg Sanitary District is also involved in this project. In FY 1999-2000, the City was awarded an ESRI Local Government Start-up Grant and hired a full-time GIS Analyst to develop and promote a Geographic Information System for use in City operations. The City of Galesburg acquired 6-inch resolution digital orthophotography, contours and planimetrics in 2001. In 2003 the City of Galesburg and Knox County entered into an intergovernmental agreement to develop a digital cadastral. The City of Galesburg has also developed most of the traditional municipal GIS layers. To date, all City departments and several other organizations in Knox County have made use of GIS analysis and products. GIS has also been used in City Council meetings and work sessions as an aid in discussing spatially significant issues. The City of Galesburg has used numerous ESRI software tools including ArcIMS and ArcReader to distribute GIS-based tools and information throughout City and County

  • perations.

Current goals are to use GIS to make the City's knowledge more available to City staff and the general public. As digital geospatial information plays a larger part in government operations, the need for data with a greater spatial accuracy and temporal significance has become apparent. Our 2001 digital orthophotography has been valuable, but is now in need of updating.

1.3 Tentative Project Timeline (pending acquisition suitability) October 2 - Issue RFP November 3 - Proposals Due November - Contract Negotiation November / December - Issue Contract Spring ‘07 - Orthophotography Acquisition Summer ‘07 - Digital Orthophotography Delivery / Evaluation Specific enforceable project milestones, delivery dates and penalties will be specified in any contract issued by the City of Galesburg.

  • 2. Scope of Work / Specifications

Prior to obtaining aerial photography, the vendor will submit a flight plan including flight dates & times, flying height, negative scale (if applicable), the estimated photographic footprints of each flight line, planned endlap and sidelap, camera and aircraft specifications and a current calibration report. The photography must be acquired using a forward motion compensating (or equivalent) camera and controlled by Airborne GPS. All respondents are required to submit a description of the photography acquisition and production process including a detailed discussion of quality control, including references to recognized Aerial Photography standards. 2.1. Acquisition 2.1.1.1 Update Low Altitude Panchromatic Aerial Photography – Entire Project Area The vendor must acquire new, panchromatic, "leaf-off" aerial photography on one calendar day in Spring of 2007 (pending suitability) duplicating the (49 square mile) project area of the 2001 project shown roughly in Figure 2 of Appendix 1 (extending from the southwest corner of Section 30 of Township 11 North, Range 1 East of the Fourth Principal Meridian to the northeast corner of Section 30 of Township 12 North, Range 2 East of the Fourth Principal Meridian – available for download as an ESRI personal geodatabase in the digital RFP packet at http://gis.ci.galesburg.il.us/orthoupdate/orthoupdate.zip or as a public ArcIMS service named “orthoupdate” at http://gis.ci.galesburg.il.us with username and password “orthoupdate”). The photography must be taken when the sky is clear; shadows are minimized; ground and water bodies are clear of snow and ice and deciduous trees are

  • barren. This photography will be acquired from a uniform flying altitude to preserve the

continuity of the photography.

2.1.1.2 Update Low Altitude Panchromatic Aerial Photography – Core Area Alternatively, the City requests that the vendor develop a plan to acquire new duplicate imagery of only the 32 square mile area as shown in Figure 3 of Appendix 1 and available in the digital RFP packet or online. 2.1.2 New Low Altitude Panchromatic Aerial Photography The vendor must also acquire new, panchromatic, "leaf-off" aerial photography on the same calendar day beyond the 2001 project area (the west half of Section 20 of Township 11 North, Range 2 East of the Fourth Principal Meridian and Section 33 of Township 11 N, Range 1 East of the Fourth Principal Meridian – also available in the digital RFP packet or as a public ArcIMS service) as shown in Figure 4 of Appendix 1. The vendor must also generate a new DEM for those areas or acquire an existing model that will yield orthophotography meeting or exceeding our requirements outlined below. 2.1.3 Color / IR Imagery (Optional) The City of Galesburg is interested developing color (RGB / 3-band) or False-Color Near-IR (4-band) imagery with the same specifications. The City retains the option to include this specification in any contract it may issue. 2.2 Orthophotography Production The City will supply a copy of the digital model (masspoints and breaklines) created in 2001 to support that orthophotography project as well as ground monumentation tied to same network that controlled the 2001 orthophotography. This digital model and ground control network yielded orthophotography with an NSSDA(r) error of 1.415’. The newly acquired / updated photography and airborne GPS will be processed with the supplied digital model and control to create digital Orthophotography with a pixel resolution of 6 inches. Interpolation from a coarser input resolution is not acceptable. Scanned conventional orthophotography is not acceptable. The orthophoto images will be geo-referenced to the Illinois State Plane Coordinate System (West Zone) based on the NAD83 horizontal datum. All measurements will be in

  • feet. All images will be edge-matched with gray tone and density matching with no pixel

gap between adjacent images. Orthophotos will be delivered as a single, mosaiced image using MrSID image compression and as individual uncompressed TIF/TFW images tiled to PLSS quarter sections with 200’ of overlap (see the ESRI personal geodatabase in the digital RFP packet at http://gis.ci.galesburg.il.us/orthoupdate/orthoupdate.zip for tile naming and general tile location).

All respondents are required to submit a detailed description of the orthorectification process as well as internal quality control methods. Before final acceptance, the photography will pass quality control testing as described by the National Standard for Spatial Data Accuracy (described in Geospatial Positioning Accuracy Standards Part 3: National Standard for Spatial Data Accuracy published by the Federal Geospatial Data Committee in FGDC-STD-007.3-1998) for horizontal accuracy

  • f +/-3 feet as administered by the City of Galesburg.
  • 3. Deliverables

In summation, the City of Galesburg requires at least the following deliverables:

  • A flight map showing the actual flight lines and identifying photographic

footprints, photo centers by flight line and frame (as appropriate)

  • Quarter-section tile digital orthophotographs in uncompressed, TIF format with

appropriate world files of the project area

  • A revised copy of the digital model including the new areas
  • One MrSID format mosaic digital orthophoto image encompassing the entire

project area with all digital imagery created as a part of this project

  • One set of FGDC compliant metadata for each digital deliverable compliant with

the Content Standard for Digital Geospatial Metadata Version 2.0 (FGDC-STD- 001-1998) Optionally:

  • A copy of the unprocessed images in a useable format - georeferencing is not

expected or required

  • The above supporting Color / IR Imagery

The City of Galesburg reserves the right to modify these deliverables during contract negotiation.

  • 4. Quality Control

4.1 Vendor QC/QA As outlined above, all respondents must include detailed descriptions of their internal Quality Control / Quality Assurance methods. The successful respondent will ensure the compliance of deliverables with the project specifications and recognized Aerial Photography standards before submission to the City for final acceptance.

4.2 NSSDA Testing Before acceptance, the City will test the horizontal accuracy of the deliverables. These tests will be conducted using methods outlined in Geospatial Positioning Accuracy Standards Part 3: National Standard for Spatial Data Accuracy published by the Federal Geospatial Data Committee in FGDC-STD-007.3-1998. The deliverables will not be accepted with an NSSDA statistic for horizontal accuracy of greater than 3 feet with a 95% confidence interval. The City will identify 30-40 test points on the ground prior to acquisition. As mentioned above, the provided digital model and ground control network yielded an NSSDA(r) error of 1.415’, equivalent to meeting the NMAS for mapping at 1:442.19 (1”=36.85’) in 2001.

  • 5. Submission Instructions

The City of Galesburg will negotiate a professional services contract with the successful respondent. Favorable pricing will be one factor in the selection process, but experience of the firm, input from references, qualifications, ability of the assigned staff, resources, ingenuity, completeness and timeliness of service proposed by the respondents will be significant factors in the award of this contract. The Galesburg City Council will make the final decision on selection of a firm for this project. Specific points of clarification must be sent via email or fax and include the specific sections of the RFP in question. All requests for clarification and responses will be addressed on the City of Galesburg's web site at: http://gis.ci.galesburg.il.us/orthoupdate Send requests for clarification to: James Cueno, GIS Analyst, City of Galesburg E-mail: jcueno@ci.galesburg.il.us Voice: 309-345-3690 Fax: 309-345-5704 By 4:00 PM local time Friday, October 27, 2006 Send proposals to: Kraig Boynton Purchasing Agent City of Galesburg 55 W Tompkins St Galesburg IL 61401 Proposals due by 4:00 PM local time on Friday, November 3, 2006
