Aloha kakou,
Saturday marked the completion of the 2012 Geospatial Research and Mapping field program.  Students presented their research throughout the morning with academic posters.  The work completed over the past month was impressive in its scope and sets the stage for future research projects.  Discussion was initiated pertaining to project topics.  The way in which […]

Map making and academic poster construction

Aloha kakou,
This morning was spent preparing maps for my research presentation tomorrow morning.  My academic poster is titled Remote Sensing and Ancient Polynesian Landscapes.  Last month, I set out to determine what remote sensing platforms and methods are most effective for the identification of archaeological features.  I determined that LIDAR-derived imagery was the best approach […]

LIDAR image analysis

We obtained the LIDAR data for our focus area of the Koloa field system.  Manipulating the histogram parameters creates workable imagery showing pre-contact habitation platforms and agricultural fields in a well-defined medium.  Hillshade digital elevation models were constructed based on this information.  The resulting hillshades are helpful in revealing anomalies in natural terrain.  Areas of […]


I hope everybody had a safe 4th of July.  I went to the computer lab first thing in order to check the results of some overnight image sequencing processes.  The program I am using failed once again to mosaic all of the compiled photographs.  I will begin experimenting with smaller batch runs in Photosynth and […]

Data processing…

Our research hui is busy generating large amounts of data.  Today consisted of 9+ hours in the lab reviewing KAP images and reorganizing  photographs for subsequent work.  I am trying to create a viable orthophoto for the Koloa field system.  A photoscan mosaic was attempted last night for 1082 photographs.  The resulting image was not […]


Good evening,
This morning began a long week of data processing.  I began the day with orthophoto creation from KAP and UAV data of Koloa archaeological  preserve 1.  True-color and near-infrared mosaic images were constructed primarily through the use of Agisoft Photoscan.  The images were then georeferenced, that is tied into coordinates determined by global positioning […]

Ua hoi au i kaliponi no ka hana nui

Aloha kakou,
I nehinei makou i haalele ai mai Kauai mai i ke kula nui ma kaliponi.  Pono au e hana nui ma anei e hoopaa kou hana no keia papa.  Ma hope o kou hoopau au e hoi ai i kuu ohana i Kaimuki.  Mahalo au ia na kanaka e kokua ai ko makou hui […]

Kaumaha au i kou haalele ana mai Hawaii nei

This morning was spent  processing KAP and UAV-acquired imagery while preparing for tomorrow’s travel to Long Beach.  Bags were packed and orthophotos were created.  I reworked several images of the Koloa field system in efforts to improve the resolution and accuracy of the photograph mosaics.  My attempts appear to have been in vain as image […]

Data processing…

Remote-sensing information acquisition has ceased.  Data processing has been ongoing throughout the duration of this program, but efforts will be stepped up over the next several days.  I will be compiling aerial photographs for portions of the Koloa field system as part of an imagery collection for Teddy Blake.  Today, I created lower quality orthophotos […]

Soil sampling and research updates

Aloha kakou,
We returned to the Koloa Field System this morning for soil sampling and more KAP.  We laid out two 100 meter transects and then took samples along those transects based on feature appearance.  Soil samples will be analyzed with our portable X-ray fluorescence unit and elemental compound information will be used for comparative analysis.
