1 Consolidation and Distribution of Infrastructure Data Using Geospatial PDF Richard McKay, S.V.P TerraGo Technologies

2 What is a Geospatial PDF? A geospatial PDF is a standard Adobe PDF with additional metadata that allows points on the PDF page to be accurately converted to geospatial coordinates. Invented by TerraGo Technologies in Geospatial PDF is an open standard, defined by: ISO32000 PDF specification OGC GeoPDF Encoding Best Practice Version 2.2 Supports over 3,200 datum/projections Allows the consolidation of multiple formats into a single secure file. 2

3 Features of Geospatial PDFs When used with Adobe Reader and the free TerraGo Toolbar, Geospatial PDFs provide essential map viewing capabilities. Manage layers Display feature attributes Display and zoom to coordinates Measure distances and areas Interact with GPS devices Collect field data with forms and markups Import shape files, KML and GPX data 3

7 The Japanese Earthquake and Tsunami The March 11, 2011 earthquake and tsunami resulted in over 180,000 applications for building damage compensation, each of which required inspection before acceptance. Much of the damaged area was inaccessible due to radiation exposure from the Fukushima nuclear power plant disaster Hitachi Solutions proposed to deliver GeoPDF maps for the entire area by combining post-disaster satellite imagery, SAR flood estimate and cadastral boundaries. Using the TerraGo SDK, over 42,000 GeoPDFs were created in 48 hours for delivery to the Japanese cabinet. Using these maps, field workers were able to issue Diaster Victim Certificates for the inaccessible area. 7

11 Pennsylvania One Call The problem: underground excavation may threaten many utilities infrastructure. Utilities data is stored in many different systems: Esri Smallworld MapInfo Bentley Systems AutoCAD Design firms submit plans defining a construction area The TerraGo SDK is used to consolidate all sources and create a single GeoPDF revealing potential conflicts 11

15 Sewer facilities 15

16 Water facilities 16

17 Fiber optic facilities 17

18 Results Both use cases demonstrate the consolidation of multiple data sources and types into a single, simple format. Non-GIS professionals are able to access large, complex geospatial data. Small file sizes ease distribution. The client software is free: Adobe Reader and the TerraGo Toolbar. 18
