Depends on the Project Requirements

Example 01

• Large Areas• Purpose: Base Mapping• Difficult to Obtain Control Points or Want to minimize the Cost of

Survey• Large Scale Mapping• Deliverables: Orthos, Contours, DTM…etc• Flying Permits Easy to Obtain• Timeline is not critical

Digital Aerial Photography Technology

(Push Broom or Frame Based)

Pixel Factory

Multi-End Products

Multi-Sensor

Multi-Data Source

Pixel Factory throughput is about

3 times less labor intensive

High capacity and native open architecture is able to automatically process vast volumes of raw earth observation data from multiple sensors and produce a wide range of cartographic end products (e.g. Digital Surface Models, True Ortho, and Ortho mosaics)

A Federal Security Agency

The Federal Security Agency has multiple standalone systems.Among these systems, data can exist in different formats,

different coordinate systems, and different business systems.

The Agency needs to be able to consume all this dataAnd offer it to various stakeholders as a standardized, seamless and

integrated dataset
