1. Basic Geospatial Analysis Techniques

2. What is geospatial data analysis?
Application of operations to manipulate or calculate coordinates and/or related attribute data
Applied to solve a problems such as…
Bus routing
Flood zones
Suitable site determination
Spatial data analysis uses spatial operations to manipulate or calculate
‘SDA’ will be used to refer to ‘spatial data analysis’ for the remainder of this lecture.

3. Analysis Flowchart for Delineating Watersheds

4. Input, Operations, and Output
SDA typically involves using data from 1 or more layers to create output
One to One
One to Many
Many to One
Many to Many
Output may not always be spatial
Statistics
Reports

5. Seven Basic Geospatial Analysis Techniques will be Examined
Selection
Buffering
Dissolve
Overlay Operations
Classification
Table Operations
Geocoding
