71st SWCS International Annual Conference July 24-27, 2016 Louisville, KY

1. Soil and Water Conservation Society
2016 Annual Conference
Louisville KY – Galt House
Tuesday July 26th, 2016
Demetrio P. Zourarakis, Ph.D., GISP, CMS‐RS, CMS‐GIS/LIS

2. Erosional Pattern Recognition
or
Saving Dollars with GIS and Remote
Sensing
or
‘Information’ (as opposed to ‘data’)
Conservation
or
Spatial Intelligence in Conservation
or...

3. $aving$ because...
• Shrinking budgets
• Staffing issues
• Changing climate patterns
• GIS (geospatial)+ IT ...
– Cloud
– UAV/sUAS
– Next Gen LiDAR
– IoT
– Etc. etc. etc.

4. The case for photointerpretation
• Available data
– NAIP (4‐band, 8 bit, biennial, 1‐meter)
– LiDAR
• Data/Information layers – REST services
– Readily available
– Cloud storage
• Image enhancement
– COTS
– Open Source

5. The case for image
classification/feature extraction
• Processing power and memory capacity
– Ubiquitous
• Data/Information layers – REST services
– Readily available
– Cloud storage
• Image enhancement
– COTS
– Open Source

6. Where to begin?
• Keep in mind objectives
– Soil erosion control?
– Streambank restoration?
• Extent (“scale”) of Area of Interest?

7. Examples

9. Active Soil Erosion
• Hopkins County
• Western Coal Field Region
• Green River Basin
• 2014 NAIP
• 2014 KYAPED
• 5‐foot LiDAR DEM

15. Streambank Erosion
• Scott County
• Inner Bluegrass Region
• Kentucky River Basin
• 2012 NAIP
• 2012 KYAPED
• 5‐foot LiDAR DEM

21. Erosion/Karst
• Shelby County
• Outer Bluegrass Region
• Lower Ohio ‐ Salt River Basin
• 2012 NAIP
• 2012 KYAPED
• 5‐foot LiDAR DEM

27. Where to...?

28. TWO ACRONYMS TO KNOW –building blocks in the Cloud!
REST: Representational State Transfer – a simple, open Web interface to
access services hosted by ArcGIS Server
URL: Uniform Resource Locator – a Web address – such as that for the
endpoint for a GIS service published to ArcGIS Server:
• http://kygisserver.ky.gov/arcgis/rest/services
(Web Mapping Services: e.g. KY Schools service)
• http://kyraster.ky.gov/arcgis/rest/services
(Image Services: e.g. Imagery and Terrain)
• http://services.nationalmap.gov/arcgis/rest/services
(Geonames)

37. UAV/UAS or “Drones”
• Disruptive technology
• DIM (Dense or High Density Image Matching)
• Point Clouds (Elevation) *from images*
• Not LiDAR
