Increasing awareness, understanding and appreciation for efforts to increase expeditionary engineering and logistics capability is a continuous challenge.
SeaBees and Marines collaborated to rapidly scan all relevant features of a small island and surrounding waters off Okinawa
to begin realizing the art of the possible for new engineering reconnaissance capabilities.
Emerging capabilities show that 3D scanning, collaborative 3D scenario visualization, and 3D printing of models are all closely interrelated.
This work demonstrates that rapid in-stride digital collection of tactically useful information is feasible.
SPIDERS3D goals include estabilishing pipelines for distilling such data assets efficiently for Web-based collaboration.
Careful attention to metadata further enables correlation to existing model assets and innovative mashups of information in meaningful ways.
## Abstract Description
> In early June, Naval Facilities Engineering and Expeditionary Warfare Center (NAVFAC EXWC), 3rd Marine Logistics Group, Naval Mobile Construction Battalion FOUR (NMCB 4), and Underwater Construction Team TWO traveled to Ukibaru Island east of Okinawa to conduct a three-dimensional expeditionary reconnaissance—known as Poseidon Watchtower.
>
> Led by NMCB 4, the Poseidon Watchtower Exercise aimed to test and evaluate concepts for conflict contingency plans drafted by the Department of the Navy (DON).

> Marines and Sailors with 3rd Marine Logistics Group and Naval Mobile Construction Battalion 4 are conducting Expeditionary Advanced Base Operations training on islands around Okinawa, Japan, during exercise Poseidon’s Watchtower from June 2-17.
>
> Poseidon’s Watchtower serves as an opportunity to rehearse both Naval integration and EABO, with Marines and Sailors from 3rd Landing Support Battalion
> and 9th Engineer Support Battalion working alongside NMCB-4 Sailors, known as Seabees, to simulate reconnoitering and establishing expeditionary advanced bases
> on the islands of Ukibaru and Irisuna off the coast of Okinawa.
