Hexacopters, Kites, and more GIS

Aloha,
I spent much of this morning with Dr. Lipo calibrating and testing the hexacopter.  The professor had installed a new motor and several adjustments had to be made in order for the unit to function properly.  We will be attaching two GoPro cmaeras, one with color-infrared modification, for aerial stereoscopic imagery.  Once the aerial equipment […]

Georectification and hillshades

I have spent the majority of today manipulating KAP (kite aerial photography) acquired imagery for the creation of DEMs (digital elevation models) of Hoouluia heiau.  Lawrence, Paul, and I started with the georectification of aerial photographs previously aligned in Agisoft Photoscan.  The image was tied into GPS coordinates obtained with a Trimble GeoXH which allows […]

Koloa Field System

The archaeological team began the day with a tour through the Koloa field system guided by Dr. Hal Hammatt of Cultural Surveys Hawaii. The Koloa field system comprises the remainder of what was once an extensive complex of irrigated pond fields (loi), habitation sites, and heiaus.  We walked the irrigation system while referencing an archaeological […]

Nani loa na pali

Aloha kakou,
Today we visited Nualolo.  We met the crew from Captain Andy’s at Kikiola and were on our way by 6am.  The morning was overcast, but the skies gradually cleared as the day warmed up.  We traveled up Na Pali and into Nualolo Kai.  Nualolo Kai is a shallow amphitheater of a valley and shares […]

Waimea and Poipu

Aloha,
Today was scheduled as an off-day.  First thing in the morning we headed up to Waimea Canyon.  Matt Lucas educated us regarding the plant communities at different elevation levels as we ascended the canyon grade.  We saw several Iliau (Kauai green sword/Wilkesia gymnoxiphium) in bloom, and Matty discussed the life-cycle, establishment patterns, and regional distribution of […]

Quarry surveys and the Gatewing x100

Post for 6-22-12, delayed due to technical difficulties:
Friday morning, our research group took an excursion to the Grove Farms Quarry located adjacent to Makauwahi Cave for a reconnaissance survey.  GPS points were taken for various features as we attempted to locate other natural resources.  We viewed the location of what was once Waiopili heiau, a […]

Hoouluia orthophotos, point cloud generation, and canoes

Aloha kakou,
PAP (pole aerial photography) was not sufficient, but the KAP (kite aerial photography) imaging worked.  I had previously mentioned the inadequate results from my PAP documentation of Hoouluia heiau.  This morning, I started playing around with photographs taken from Chuck Devaney’s kite.  Two hundred sixty-three photos were recorded on a Canon G12 attached to […]

PAP at Hoouluia

Aloha,
Today, our archaeological team recorded images for Hoouluia heiau at Mahaulepu using a pole-aerial-photographic (PAP) approach.  A GoPro HERO2 camera was affixed to the top of a large carbon fiber pole approximately fifteen feet in height.  The camera was positioned facing perpendicular to the ground and photos were recorded at ten second intervals.  Photos were […]

Hoouluia, Mahaulepu

Good evening,
Data acquisition has commenced and research projects are taking shape.  The plant research team began the day recording spectral signatures for various plant species from the vegetation grid at Makauwahi Cave Reserve.  Our archaeological team joined the hydrology group for a tour of the sinkhole.  Dr. Burney lectured on the natural processes contributing to […]

NTBG, Makauwahi, and airborne remote sensing platforms

Howzit,
This morning, our research group became acquainted with the south side of Kauai.  We began our day at the National Tropical Botanical Garden in Lawai Valley.  Dr. Burney led us on a tour of the research facilities, and then we headed down into the gardens.  NTBG has acquired a living collection of thousands of plants […]
