1. Programming vs. Packaged
Easier if what you need is available
Programming:
Takes longer, can do anything

4. Types of Languages Scripted Compiled
Each line of code is parsed, then executed
Fast to write, slow to execute
Great for data acquisition and preparation
Compiled
Entire program is compiled, then executed
Slower to write, faster to execute
Best where speed is needed
Large data prep (LiDAR, UAV)
Simulations

5. Applications w/Scripting
Excel w/VBA
R, SPSS, SAS
ArcGIS, QGIS, BlueSpray…
MatLab
Logo
Stella, GME
Browsers: JavaScript
Others…

6. Scripting Languages VBA in Excel Python R PHP Python!
Easiest to prep data in Excel
Python
Most common for GIS
Interfaces to SciPy, R R
Vector and Matrix based statistics
PHP
Was most popular for server-side-scripting
Python!
JavaScript is the most widely used scripting language but it really only is used in web browsers (IE, FireFox).

12. Python GIS Libraries ArcGIS: lots of functions, expensive, slow
QGIS API is really challenging
BlueSpray: fast, limited features, documentation, testing
GeoPandas: Up and coming?
Lots of open source libraries
Only can get it to work with Anaconda?
Not as many features as ArcPy but we can do anything in Python!
