Expedition Locates 24 of Ellicott’s Original Mounds
Surveyors
located at least 24 mounds on the historic Ellicott Line during a December
field seminar held in Andalusia, Ala. Prior to the December 2009 event, only
two of the original mounds demarcating the 124-mile line had been located.
The event was a joint effort between Auburn University (AU), which sponsored the seminar and developed a computer program to convert perches, chains, feet and meters into latitude and longitude values; the Alabama Department of Conservation and Natural Resources, which provided concrete monuments and logistical support; and co-facilitators Milton Denny, PLS, POB columnist and part-time AU instructor, and associate professor Dr. Larry Crowley, PE, of the AU Department of Civil Engineering. Participants earned 12 continuing education credits for a mandatory two days of participation.

The event began with a seminar in which 40 licensed surveyors representing Mississippi, Tennessee, Florida, Alabama and Georgia were given an overview of the mound line and provided with locations of known mounds. Afterward, six crews set out to locate the mounds based on GPS information provided by Denny. “Those mounds couldn’t have been found without the combination of old and new technology,” Denny said, explaining that most of the original 4- to 5-foot piles of earth are now only 4 to 6 inches high. Denny spent three years prior to the event developing a system to find the most-likely locations of the mounds utilizing recently discovered old maps and plats and modern GPS technology as well as perches, chains, feet and meters. Denny is waiting for confirmation from two of the crews, but he said he expects the final number of confirmed mounds to be around 40. Future expeditions to locate mounds are being planned. Once complete, Denny estimates the pro bono survey of the Ellicott line to have a value of $1.5 million.

Wisconsin Bill Requires QBS Process for Surveyors and Other Consultants
A
bill requiring the use of a qualifications-based selection (QBS) process for
certain public works consulting contracts was introduced in the Wisconsin
Senate in January. A consultant is defined under Senate Bill 442 as a person
who provides architectural, engineering, land surveying, photogrammetric,
professional geology or landscape architecture services.
Projects affected by the bill are defined as those in which any local
governmental unit requires a consultant; relates to the planning, study, design
or construction inspection or administration of the public work or building,
including the inspection of local bridges; has a total estimated project cost
of at least $250,000; and will be funded to some extent by the state.
The bill requires a local governmental unit to create a procedure to solicit proposals from consultants for projects. The proposals may not contain any information on proposed fees, level of efforts, or costs. The proposals must contain certain information about the consultants, including specialized experience, capabilities and technical competence; their quality of work and ability to meet schedules; and their proposed method of project management. The local governmental unit must rank the consultants based on the consultants’ qualifications as described in their proposals. The local governmental unit must enter into negotiations with the highest ranked consultant to finalize the terms of the contract. If the parties are unable to reach an agreement, the local governmental unit must enter into negotiations with the next highest ranked consultants, in order of their ranking, until a contract is finalized. If no agreement is reached with any of the consultants, the local governmental unit may retain a consultant for the project under any other allowable method. Additionally, a local governmental unit may enter into a contract with a consultant with whom it has an established relationship and who has previously provided similar services, without evaluating proposals from other consultants. The full text of the bill is available at www.legis.state.wi.us/2009/data/SB-442.pdf.
URISA Grants New GISPs Free Membership
The URISA board of directors voted in January to award new GIS professionals (GISP) a complimentary one-year membership valued at $175. The title of GISP is granted by the GIS Certification Institute (GISCI) to those people who have met the educational, professional experience, and professional contribution requirements as set out by the GISCI. Beginning with the December 2009 class, all new GISPs who are not already URISA members are eligible for this free membership offer. For more information, visit www.urisa.org.
Surveyors Advisory Board Launched in California
The Land Surveyors Advisory Council on Technical Standards (LSACTS) was formally announced in January. Comprising an 11-member executive board, LSACTS is modeled as an advisory “think tank.” Its stated purpose is to research, summarize, debate and publish its findings on various topics relating to the principles and applications of the Professional Land Surveyors’ Act and the California Subdivision Map Act. It also provides peer-to-peer advice to other members of the profession. For more information, visit www.lsacts.com.
Three Glonass Satellites Launched
The Russian space agency, Roscosmos,
launched a Proton rocket carrying three Glonass-M satellites into orbit on
December 14 from the Baikonur Cosmodrome in central Kazakhstan, according to RIA
Novosti. This was the year’s final launch, bringing the total number of Glonass
satellites on orbit to 22, including one in decommissioning phase and three
undergoing maintenance. The three Block 41 Glonass-M satellites, 730, 733, and
734, have been placed in Plane 1 and are in the commissioning phase at the time
of publication. According to Roscosmos, communications has been established with
all of the satellites, and performance is nominal. The next Glonass launch is
scheduled for a Feb. 11–20, 2010, window.
USGS Announces a New Generation of Maps
The U.S. Geological Survey formally introduced its
next-generation mapping product, US Topo, at its 125th Anniversary of
Topographic Mapping celebration in December 2009. Digital US Topo maps are
designed to look, feel and perform like traditional paper topographic maps while
providing technical advantages that support faster, wider public distribution
and enable basic, on-screen geographic analysis for users. “These digital maps
can be as simple or as sophisticated as the need dictates, easily customized on
the spot,” said USGS Director Marcia McNutt.
A US Topo map includes all of the content of its
prototype, Digital Map – Beta, which has been available since June 2009, plus
integrated contours and hydrographic features. Arranged in the familiar
7.5-minute quadrangle format, each map quadrangle is constructed in GeoPDF
format from key layers of geographic data found in The National Map, including
orthoimagery, roads, geographic names, topographic contours, and hydrographic
features. US Topo users can turn geographic data layers on and off as needed,
zoom in and out to highlight specific features or see a broader context, and
print the maps in their entirety or in customized sections on a wide variety of
printing devices. File size for each digital US Topo 7.5-minute quadrangle is
approximately 15-20 megabytes, which is convenient for most computer users. US
Topo maps, as well as electronic analytical tools, are available as a free
download. As of December 21, more than 885 US Topo maps have been
loaded to the Map Locator of the USGS Store, according to the National
Geospatial Technical Operations Center. Kansas is the first US Topo state
available to be followed by New York, Oklahoma, Kentucky and Texas. As the US
Topo product evolves, the USGS will provide digital, historical versions of USGS
topographic map quadrangles and incorporate additional geographic data layers
from The National Map. For more information, visit www.nationalmap.usgs.gov/ustopo.
FEMA to Re-Issue Preliminary Flood Maps for Skagit County, Wash.
The Federal Emergency Management Agency (FEMA)
announced Dec. 23, 2009, that it intends to re-issue the recently released
preliminary flood insurance maps for Skagit County, Wash. “FEMA’s intention is
to produce the most-accurate flood insurance maps possible,” said Dennis
Hunsinger, acting regional administrator for FEMA Region 10. “We regret the
problems in these maps and will resolve these issues before the maps are
finalized.”
Preliminary maps are provided in advance to communities for review and
assistance in catching technical and mapping issues before the product enters
the official appeals process. Local government officials brought mapping and
cartography issues to the attention of the agency. According to FEMA officials,
the agency remains confident in the underlying flood hazard data, but the issues
brought forward are troubling and warrant the reissuance of the maps.
Once maps are accurately redrawn, FEMA will release a revised preliminary
flood insurance map for Skagit County and restart the public feedback process.
When finalized, the maps will be used for flood insurance, land-use planning and
development decisions.
WorldView-2 High-Resolution Satellite Imagery Now Available
DigitalGlobe announced in January that
its latest high-resolution satellite, WorldView-2, achieved full operational
capability. Imagery from the satellite is available to global resellers,
partners and customers. Launched Oct. 8, 2009, WorldView-2 joins DigitalGlobe’s
existing submeter satellites, QuickBird and WorldView-1, on orbit. WorldView-2
significantly expands the constellation’s collection capacity, enabling an
annual imaging capacity equivalent to three times the area of Rarth’s land mass
and allows for intraday revisit. WorldView-2 is also the industry’s first
commercial high-resolution satellite to offer eight multispectral bands, which
provide more spectral information and allow for greater analysis capabilities,
including improved feature identification and change detection. For more
information, visit www.digitalglobe.com.
China to Launch First Civil HD Survey Satellite in 2011
China will launch its first civil
high-definition survey satellite in 2011, according to an announcement by State
Bureau of Surveying and Mapping (SBSM) officials in December. The satellite, ZY
3, will be launched from the Taiyuan Satellite Launch Center in northern Shanxi
province on a Long March 4B carrier rocket, said Xu Deming, director of the
SBSM. The satellite will operate in a sun-synchronous orbit about 506 kilometers
in altitude and produce seamless imagery of the Earth’s surface from 84 degrees
south latitude to 84 degrees north latitude. The satellite will be used for map
updates, land resources investigation and monitoring, disaster prevention and
reduction as well as serve the agricultural, environmental, urban planning,
traffic and national defense sectors, Xu said. The launch date was not
disclosed.
