Wilson, GIAC Director SUBJECT: Time and Effort Splits for Task Order#1 I have reviewed the task order that we prepared on 8/16/95 and used the GPS road survey (item 3) to allocate costs between the city and county. We anticipate that it will take 15 days to conduct the GPS road survey within the city and another 20 days to collect these data in the county. This split takes into account both the higher frequency of signs and other attributes within the city and the greater spatial extent of the county. The same splits (57% county; 43% city) should be used for the remainder of the work tasks with the exception of GIS training (Item 8; 50/50 split to provide ArcCAD training for one city and one county staff person)because the time and effort required to perform these tasks is directly proportional to the volume of GPS survey data. This allocation of time and effort leads to cost estimates of$14,295 and$18,875 for the city and county,respectively. Xc: Jackie Magnant,GIS Specialist Mountains and Minds • The Second Century TASK ORDER#1 The preparation of an accurate digital roads coverage for the City of Bozeman and Gallatin County represents a logical first step in building a digital GIS database to assist city and county government. The results from a recent joint city/county pilot project(report in preparation) indicate that Global Positioning Systems (GPS) hardware and software can be combined with Geographic Information Systems (GIS) hardware and software and used to generate a digital roads coverage (1-5 meter horizontal accuracy) and several additional data layers (milepost markers, hydrants, bridges, road signs, and culverts, etc.). Ground control points may also be created from the roads layer and used to locate subdivisions, Certificates of Survey (COS), and other features in real world coordinates. Staff and equipment from the Montana State University Geographic Information and Analysis Center (GIAC) is available to prepare the GPS road survey and final GIS data layers. The primary and secondary roads and associated features would be surveyed with a Trimble GPS receiver attached to a rooftop antennae, a laptop computer, and a GPS base station located on the roof of Leon Johnson Hall. Two people are required for data collection. One person is needed to navigate the vehicle and the second person is required to (1) check data integrity(the GeoLink software draws the road data in vector format (i.e., as lines represented by suites of x,y coordinate pairs) on the laptop monitor as the data are collected) and(2)enter the attribute data(milepost markers, hydrants, bridges, etc.) in a series of customized database files. This survey should be initiated no later than 4 September 1995 to minimize possible (winter) weather delays. The final GIS coverages would be prepared in ARC/INFO and the deliverables would include a project report and a series of digital ARC/INFO coverages (data layers). The following cost estimates and timetable were prepared from the results of the pilot study and recent meetings between city, county, and GIAC staff about potential data products: 1. Organize and coordinate data collection,data processing, and preparation of reports (monthly progress reports submitted with invoices for services and final project report) 6 days at$240 per day $ 1,440 2. Identify section corners and determine final routes for data collection 4 days at$240 per day 960 3. Conduct GPS road survey 1 GIS Specialist x 35 days at$240 per day 8,400 1 Graduate Research Assistant x 35 days at$160 per day 5,600 4. GPS equipment rental (from Department of Plant, Soil and Environmental Science at Montana State University) Base station ($875 for 35 days x 50% discount) 440 Pathfinder roving receiver with GeoLink software loaded on GIAC laptop computer (35 days at$100 per day x 50% discount) 1,750 Differential corrections (35 days at$30 per day to be performed by Diana Cooksey, GPS Technician) 1,050 5. Convert GPS data to ARC/INFO coverages, identify and correct spatial database errors 33 days at$240 per day 7,920 6. Identify and correct errors in road coverage attribute database 15 days at$240 per day 3,600 7. Adjust PLSS section corners with GPS survey results 4 days at$240 per day 960 8. Gallatin County/City of Bozeman staff training 3 day ArcCAD training 1050 Informal"hands-on" training as part of data collection and analysis work tasks (no charge) 0 9. Vehicle costs (35 days) Anticipate using city and/or county vehicles and fuel 0 TOTAL COST LESS CAR AND WITHOUT CITY/COUNTY STAFF CONTRIBUTIONS TO DATA COLLECTION EFFORT $33,170 Four actions are required to implement this task order: (1) the Memorandum of Agreement for GIS collaboration between Gallatin County, the City of Bozeman,the City/County Planning Board,and the Montana State University Geographic Information and Analysis Center must be finalized and executed; (2) the list of attribute data to be collected and the protocols used to collect these data (offsets (if any), attribute codes, etc.) must be determined; (3) the role of city and/or county staff in data collection and data analysis efforts must be determined (their participation may reduce overall project costs,the availability of GIAC Graduate Research Assistants,and the final timeline for some project tasks); and (4) the project start and finish dates must be determined. We would need approximately four months to complete the work tasks and prepare the final report and database products.
