Outline

• Imagery is more than a basemap

• The Geomatica Platform

• Advantages of working with Python

• Geomatica and ArcGIS Python APIs

• Sample Script/Demonstration

Background

PCI Geomatics has been a leader in developing

software for processing and analyzing remotely

sensed data for over 30 years!

Get More From Imagery

What are we best known for?

Software for ortho/mosaic of remotely sensed images

We make it possible for users to “get the geometry right”

Making “basemaps”

Typical image/basemap

Get More From Imagery

Is there more being done with imagery?

Yes!

Imagery CAN BE more than a basemap.

How can PCI and partners can leverage this, and

Get More From Imagery?

Agricultural Information

Elevation Information

Forestry Information

3D City Information

Maritime Information

What Does PCI Provide?

• We provide a solid environment to make it

possible to get this information• Proven science, algorithms (550+)

• Desktop / Server / Cloud

• Development Platform based on Python

What Can You Do?

• Understand customer challenges and leverage the

platform

• Develop Purpose Built Solutions (apps) that address

these challenges

• Replicate the solutions by vertical market, in different

geographies

• Create different vertical market apps

PCI Geomatics

Geomatica 2014 release includes a new

Python API for our more than 550 geospatial

processing and analysis algorithms

Platform

Geomatica & ArcMap as Platforms

The Python Advantage

The Python Advantage

• Easy to learn, high level scripting

• Growing community, body of knowledge

• Easy to create top down, logical and linear

scripts

• Also can be used to create complex

workflows

• Python serves as the glue to connect

functions between different software

packages

The Python Advantage

Python is one of the most popular scripting languages in the

Geo-spatial industry; supported by commercial and open

source packages

Geomatica & ArcGIS APIs for Python

Geomatica & ArcMap APIs

API – The API (Application Programming Interface)

provides users with instructions of how to access

objects, their attributes and call functions

Geomatica & ArcMap APIs

PCI and esri have both developed python APIs for

Geomatica and ArcMap, respectively.

These APIs make it simple for users to pass

parameters and launch algorithms within a python

script

Geomatica & ArcMap APIs

ArcPy – Important to note that the ArcGIS x64 background

processes must be installed and used if you want to

incorporate PCI’s python library in your script - PCI’s library is based on 64bit code

- Must use the same bit-depth in the same script
