Mapping Capital Improvement Program Projects at the City of Austin Mapping Capital Improvement Program Projects at the City of Austin Presentation Transcript

  • Mapping Capital ImprovementProgram Projects at the City ofAustinLogan Pugh – Programmer AnalystBen Vanderford – GIS AnalystAnnie Van Zant - Project Coordinator April 8, 2013
  • The Capital Improvement Program Projects can cost millions of dollars to design and construct: Animal Services Center, Water Treatment Plants, the Street Reconstruction Program, the new Central Library, Park and Facility Improvements Funded by the following voter-approved bond elections utility revenue bonds grants the capital budget
  • Why Map These Projects?  Replace “elevator project coordination”  Improve situational awareness  Create dig-once opportunities between City departments and other agencies/municipalities  Provide information to citizens  Assist with business reporting  Account for traffic control, special events planning, and hauling routes
  • The Process1. CIP Project Managers maintain information in a project management database2. Project Managers contact their department’s GIS coordinator(s) to map their project with the project ID and approximate limits of construction3. An FME workspace runs nightly on FME Server:  Integrates each department’s source features into one polygon feature class in an SDE geodatabase  Joins the polygon feature class to the project management database using the project ID, adding key project coordination information  Custom change detection technique is used to perform incremental updates/additions/deletions
  • The FME Workspace
  • Key TransformersSQLCreator  Used to query the project management database – creates a feature for each record returnedFeatureMerger  Used to join the attributes of the project management database to the departments’ source features.  Also used in change detection to take the appropriate attributes from either the original or the updated features.SchemaMapper  Allows us to use external files to define how attributes and values are mapped from departments’ source features to the CIP Feature Class.  Also used to map large number of different project types in the project management database to a more manageable number for symbolization in GIS and web applicationsCRCCalculator  Given a set of attributes and the geometry of a feature, produces a unique “check value” that can be stored and later used to compare against the same feature in order to determine whether it has been modified since.
  •  This part of the workspace reads in our source features and queries the project management database. Then we map the attributes of both streams of data into a common schema.
  •  Here we join the records from the project management database to the source features on the project ID We also map the large number of project types from the project management database to a smaller number of project types using an external lookup table
  •  Here we buffer point and line features so that the all the output features are polygons. A fixed buffer amount of 20 feet is used, although we could allow for different buffer amounts for different types of features.
  •  We calculate a CRC for each incoming feature and compare it against that of the feature stored in the SDE feature class.
  •  We also check whether the feature was added or removed depending on which port of the FeatureMerger it comes out of
  • IMMPACT Infrastructure Management, Mapping, Planning, And Coordination Tool  Web-based mapping application  First City of Austin application to show CIP projects and permits together  Explorer View: shows CIP projects and permits in a geographic context  Details View: lists potential conflicts & opportunities for any given CIP project or permit  Reports View: users can query CIP projects and permits based on defined criteria
  • Lessons Learned  Use database of record information  Need create a 1-to-1 relationship between projects & features  Create a culture of cooperative planning efforts between departments to establish standards and best practicesFuture Recommendations  Take advantage of new features in FME Server  Provide project information to the public  Include other departments with CIP mapping  Create a similar process for projects not funded by the CIP
