Geospatial Imaging ChainImage tools exercise an end-to-end workflow refining data into information

CAPTURE Hardware and software obtain, record and store geospatial dataREFERENCE Workstations and software solutions help users associate captured data sets to the earth’s surface

MEASURE Photogrammetric and imaging tools facilitate measurement and content extraction from the data source, creating useful information

ANALYZE Once relevant information is extracted, it is examined to identify relationships

PRESENT Geospatial information can be presented in traditional formats, visualized using 2D or 3D viewers, stored in a database and/or updated

Land Management and Cadastre

Imagery integrates real-world applications


Applications and ImageryNational Mapping

• Source data to maintain cadastreAgricultural 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 imagesState and Local

• Geostor


Imagery for the Enterprise

Satellite SensorsAirborne Digital (sensor-based)LIDAR create elevation / identify and extract features

Continuous, scalable data

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”)

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

The BIG Picture

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!

Multi-vendor direct accessGeoMediaArcGIS

• 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

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……

HDS is a growing and significantBut - 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

Terrestrial HDS rapidly being adopted for engineering, architecture, etc
