fme spatial querying in a cad-driven gis
DESCRIPTION
Ponderosa has used AutoCAD Map 3D and Microsoft SQL Server as its primary GIS for over 10 years. Having DWG objects stored with real world coordinates has allowed Ponderosa to manage its telecom infrastructure by providing accurate locations for underground locators, footage information to qualify available services as well as detailed maps for engineering and planning purposes. In the past 5-years, regulatory requirements have relied more and more on GIS data to support reports that require a variety of GIS layer overlay including Census Blocks, Census Tracts and Zip code Boundaries. Limited GIS tools in AutoCAD have proven to be inefficient and time consuming in running some the required queries and analysis. This class will focus on how FME's robust GIS querying functionality was used to save hundreds of hours in querying and analyzing GIS data stored in AutoCAD Map 3d and SQL Server.TRANSCRIPT

FME
MS SQL Spatial
Web Based GIS Enhanced Spatial Querying Abilities
Uses for FME
! Nightly data conversion to SQL Spatial ! Conversion of data to KML for special projects ! Conversion of data to DWG for mobile solution ! Data clean-up on AutoCAD drawings ! Ad-hoc GIS queries
Advantages to data in MSSQL
! Centralized location for web-based maps (Mapguide)
! FDO ready format for GIS Analysis in AutoCAD Map3D (Buffering, Overlay, Theme etc)
! Ability to do spatial queries within MSSQL ! Spatially driven MS SQL Reports (SSRS)

Spatially Driven SQL Reports
! Utilize spatial data to drive SSRS reports ! Reports that allows end user to run a query
without realizing they are doing GIS

Customizing Census Block Layer
Creating Buffered Project Layer
Overlaying Census Block and Zip Codes on Subscribers
Impact of proposed sites on subscriber broadband availability
! 0-2.5kf – 50mb ! 2.5- 5kf – 30mb ! 5-7.5kf – 20mb ! 7.5-10kf – 10mb ! 10-15kf – 6mb ! 15-20kf -3mb ! >20kf – Not Available
Time Savings with FME
Using GIS tools in AutoCAD Map 3D (2 hours and 25 minutes) ! 5 minutes to create each
band (about 16 bands total) 1 and half hours total
! Another 2-3 minutes for each overlay (additional 45 minutes)
Using GIS tools in FME (5 minutes and 5 seconds)
! Create workspace - 5 minutes
! Run workspace – 5 seconds/band
