GIS Communications System Survey.

Project Owner: NAVFAC Marianas

Project Description: Project Description: HIES developed an accurate GIS data for communications infrastructure utility system characterizing the “Outside Cable Plant” infrastructure.  HIES reviewed and analyze existing government reference documentation and developed a GPS point feature class and data dictionary that was used for field data capture.  Field data was collected using the RTK method which resulted in a horizontal accuracy of approximately 4cm. For this effort, a Trimble base station which broadcasted RTK correction information via a Pacific Crest PDL external radio and Trimble R8 ver.2 receivers and TSC2 controllers were used as a rover to collect field positions and to verify/enter attribute data.  A survey done by Towill in 2005 included several island wide survey markers. Additional markers were recovered and surveyed by HIES in 2011. This collection of markers represents a consistent network of baselines and was used as control to extend that network to include at least one point on each of the installation areas for which Communication system data is to be collected.  All collected data was complied with NSSDA standards for horizontal and vertical accuracy, SDSFIE standards for data structure and attribution, FGDC metadata requirements, and NAVFAC models. 

Baseline Monitoring AAFB and GDB Development.

Project Owner: NAVFAC Marianas (DPRI)

Project Description: The project scope included design, de-leading, hazardous material testing (EA), and erosion control implementation of Range C through F, and hazardous soil remediation for the Old Pistol Berm located in the Puuloa Training facility at Ewa Beach, HI. HIES provided all design documents, as well as as-builts for this project, and worked in coordination with OSHA and the EPA.

HIES utilized civil, structural, GIS, and Geophysical engineers for berms C through F to control soil, slope, and water erosion on the berms. The erosion design was implemented due to the possibility that erosion would cause the primary and secondary berms to leach into the ocean and the possibility of collapse due the undermining of the berm caused by natural erosion and bullet impact.

The de-leading process used a wet dry soil separation method from a mobile equipment where HIES physically performed lead, UXO, and metals remediation. The rifle range uses .45 Caliber, .38 caliber, Shotguns, M-16, and up to a 7.62 caliber where upon impact, some of the rounds would explode to fragmented pieces. To clean the fragmented lead and whole bullets including shells, penetrators, and shots, HIES utilizes a 4 screen/hopper, trommel, and soil washing system where even 1/4 inch lead fragments are isolated from berm rocks of equal size through a segragation method. This mobile system is cost effective due to its ease of transport and size thus enabling the company to minimize the range facilities closure time and exposure. If UXO / Live rounds are not detected during physical exams, the dirt is passed through a heavy steel compartment of screens where it will most likely be detected. This compartment protects labor personnel against discharge. This new method greatly reduces maintenance cost of traditional earthern berms and will also save the clients from investing in costly bullet trap alternatives. Calculated mixtures of fill replaced original materials and is anticipated to reduce future maintenance costs by 50% or more.

Soil, water, compaction, and air monitoring testing were conducted at different phases of the project to test hazmat levels at all firing lines for training safety purposes. These tests were conducted to measure lead and contamination levels that may affect the health of shooters.

Satellite Mapping of Guam and Static Survey.

Project Owner: NAVFAC Marianas

Project Description: 

HIES acquired  satellite imagery for the entire island of Guam at 40 cm resolution and 8 band multispectral imagery; and mosaic the images to produce a “less than” 2% cloud free image. The image was georeferenced, ortho photo, and tiled.  The satellite orthoimagery consisted of 41cm pan-sharpened blue, green, red and near infrared channels. These 4 bands co-registered to each other, and was orthorectified using satellite ephemeris and rational polynomial coefficient information, an existing set of 2009 aerial photographs, along with LiDAR DEM, ERDAS Imagine, and 2005 orthoimagery.  A second satellite orthoimagery of 8 bands with blue, green, red, near infrared red, but also including the additional 4 bands of coastal blue (400-450nm), yellow (585-625nm), red-edge (705-745), and NIR2 (860-1040nm) was acquired for this deliverable.   Cloud patching consisted of using Erdas and other mosaic tools; but all data was preserved as original so not to corrupt any original spectral background information.  This effort also consisted of surveying the coordinate systems used on AAFB to determine the shift between the established 1993 coordinate system and the coordinate system newly created by Towill in 2005.  Results of CORS AAFB showed the shift between GPS data differentially corrected to Guam’s CORS stations versus the same data differentially corrected to Andersen’s base station. All collected data was complied with NSSDA standards for horizontal and vertical accuracy, SDSFIE standards for data structure and attribution, FGDC metadata requirements, and NAVFAC models.  HIES deployed several Trimble R2 survey grade GPS equipment using TSCE controllers running the data collection software to preserve accuracy.  The Database was also developed in ArcGIS SDSFIE-compliant Personal GeoDatabase (PGDB).

Contour Map Creation of Tinian and Pagan, MARFORPAC, 2011

Project Owner: NAVFAC PAC

Project Description: HIES created topographic contour data of the Commonwealth of Northern Mariana Islands (CNMI) of Tinian and Pagan to support US Marine Force Pacific training exercises. The topographic contour data of Tinian was generated at a 5 foot contour interval from existing 30cm color stereo imagery previous collected by HIES. The raw ortho imagery and supporting ancillary data such as ABGPS, IMU data and ground control survey points were used for the generation of contour data meeting the specifications detailed below. Ground control of Pagan and Tinian was collected by HIES personnel using GIS base station equipment. Due to the short timeframe and abundant cloud cover in the Mariannas, HIES used photogrammetric techniques rather than hyperspectral techniques to create contours of each island thus saving the clients over 70% of the original cost.
