Imagery and the Location-enabled Platform in State and Local Government

Transcription

1 Imagery and the Location-enabled Platform in State and Local Government Fred Limp, Director, CAST Jim Farley, Vice President, Leica Geosystems Oracle Spatial Users Group Denver, March 10, 2005 TM

2 TM Discussion Overview Imagery in state and local government Crucial role of spatiallyenabled enterprise platform Geospatial Image Chain in state government An enterprise approach to using imagery for decision support in State and Local Government Introducing Geostor Requirements for Geostor Supporting State and Local Government with Geostor Enterprise platofrms supporting interoperability Open access across state government LIDAR, Point Clouds and other image data in the enterprise platform

3 TM Scope of Discussion State and Local Government Raster Imagery and High Density Survey Location-enabled Platform

4 Platform Infrastructure TM Locations (points) Graphs (networks) Parcels (polygons) Imagery (Raster) Location-enabled Platform Data Structured Networks (topology) Addresses (geocoded points)

5 Working with Imagery TM Remote sensing software Photogrammetric software Orientation management Photogrammetric software 3D Visualization software Geographic Imaging Stereo feature extraction software GIS technology Map creation Image processing software Hyperspectral tools Point Measurement Aerial Cameras Photogrammetric scanners Feature extraction Airborne digital sensors Airborne LIDAR sensor

6 Geospatial Imaging Chain TM Image tools exercise an end-to-end workflow refining data into information CAPTURE REFERENCE MEASURE ANALYZE PRESENT Geospatial Hardware Photogrammetric Once Workstations relevant and information software information and and software imaging can obtain, be is extracted, presented solutions tools record facilitate and it help in is store traditional examined users measurement geospatial associate formats, to identify data and visualized using content relationships captured 2D extraction or 3D data viewers, sets from to stored the data earth s in a source, database surface creating and/or useful updated information

7 TM Why Imagery in the Platform Global coverage Scheduled Acquisition Flexible, economic can be Tasked Centimeter to kilometer resolution Most widely recognized geospatial information Easily understood Useable in broad X-section of Business, Decision-support and traditional GIS Infrastructure for Mission Critical Applications

8 TM Imagery, High Density Survey (HDS) and Grid-based Raster Data Products are Costeffective, Renewable Geospatial Data Resources

9 TM A Range of Data Image-based Ortho-image Multispectral Hyperspectral Grid-based DEM, DTD Sensor-based Point Cloud (HDS)

10 Acquired from a Range of Platforms TM with vegetation w/o vegetation ALS 50 from Leica Geosystems Airborne Laser Scanning fast digital terrain model

11 Digital Image - Data to Product Workflow TM

12 Imagery and Platform Technology TM Business Intelligence Asset Management Enterprise GIS Defense - Emergency Response Image-enabled Data Platform Land Management and Cadastre Utilities and Transportation Imagery integrates real-world applications

13 Applications and Imagery TM National Mapping Source data to maintain cadastre Agricultural Census Administration of crop subsidy programs (IACS etc.) Road Network Database Development/Maintenance Augment mature network databases with new vectors extracted from images Enterprise Asset Management Track assets and identify changes over time Tax Assessment Locate and monitor changes in the land-base, new vectors extracted from images State and Local Geostor

14 TM Imagery for the Enterprise Satellite Sensors Airborne Digital (sensor-based) LIDAR create elevation / identify and extract features Continuous, scalable data AVHRR 1Km QuickBird 1m LIDAR Digital Airborne 5cm

15 GeoStor requirements Different types of consumers Technical/scientific, agency/government, planners/commercial, public, etc. Need to integrate into existing processes, science models, business workflows etc. Avoid YAMP ( Yet Another Mapping Portal )

16 GeoStor System Oracle (8-9i-10g) based 5+ TB of geographic data Operational since Jan 2002 Data distribution component Web-based public access Only requirements are web browser and Java Imagery requests exceed all others by an order of magnitude

17 Other Oracle 10g GRID Computing The BIG Picture GeoMedia AutoDesk ArcGIS ArcIMS aps ArcIMS ESRI SDE IONIC Red Spider WMS Oracle 10 g based Server Internet/ Intranet Java Server + espatial Leica Many Others OGC client espatial client

18 Importance of Oracle native data types With BLOBS Contents are unknown to DBMS Managed by 3rd party software All operations external to DBMS Reduced security BLOBs do not reflect known data types Multiple clients require multiple instances of blobs With Oracle object-native Full interoperability Full DBMS operations With 10g imagery in now supported as native type! Makes GeoStor possible!

19 Multi-vendor direct access Desktop clients from multiple vendors can access the same Oracle feature classes Secure requires IP address, login, password and (if needed) further identification With adequate network bandwidth data appears local Read or read/write ArcGIS GeoMedia Oracle Geodata Server AutoDesk Leica

20 Public access via OGC Compliant Web Mapping Internet e.g. The National Map s OGC Compliant Map Client GeoStor supports WMS and WFS Firewall IONIC Red Spider WMS Oracle Server

21 Imagery in GeoStor for. Flood management Facility and retail site selection Real estate transactions Growth analysis and planning Environmental compliance And on and on and on

22 HDS is a growing and significant But - datasets are massive and usually exceed capabilities of most spatial software All returns Bare earth Recent NWA LIDAR ALS-50 acquisition exceeds 800 Million points

23 Terrestrial HDS rapidly being adopted for engineering, architecture, etc
