THE PROOF

MODIS Satellite imagery overlain with the  Burning Man 2006-10 sites gives some insight.

This satellite imagery enhanced to detect water are shown for approximately every day of 2011 (very cloudy days have been excluded).  Note, the Julian calendar measures the Nth day of each year.  i.e. Day 1 = Jan 1, Day 365 = Dec 31.

SEE FOR YOURSELF

Live imagery can be viewed daily on the Friends of the Black Rocksite

Imagery details: 250m resolution Terra bands 7-2-1, please see the Modis FAQ for more details.

WHAT DOES THIS MEAN ?

Please see our concerns for long-term, cumulative effects on the playa caused by increased use.

Our observations from July 2011 to be posted here soon.

There are a number of technologies to choose from for the delivery of maps and spatial data. The 'best tool for the job' depends on the audience, the data, and the project goal.  There is no one right choice.  As technology progresses, even today's best choice  might soon be surpassed by newer options and toys.

TerraGo Technologies GeoPDF

This is a widely adopted format for many purposes.  For example, most of the USGS topology maps have been converted to the format.  BLM's internal document management system also incorporated GeoPDF.  This biggest advantage of this format is that GeoPDF maps are opened for viewing by Adobe PDF Reader.  Most have this Adobe Reader on their computer. No special software is needed to view these maps.  To create routes and comments, a small but free GeoPDF toolbar is needed.  

While the route data is not of insignificant size itself, the reference layers were very large.  The inclusion of topology and other large background maps make downloading the maps formidable via slower Internet connections.  Primarily for this reason, Google mapping tools were chosen for the distribution of map data to the public.

The original GeoPDF project description and files remain posted here for your reference.

The Race Route GeoPDF map allowed for the exchange of race data and comments directly via an interactive map containing not only documented, approved routes but reference data essential to race organizers and BLM staff alike. 

The GeoBook will display any files for which the users computer has the supporting software.

Objectives

The Black Rock country is primitive, vast and remote -- a good place to “know before you go.” You can do that with a free CD, the Black Rock NCA eBook. It is loaded with information using a variety of media including interactive maps, videos and photos. You’ll also learn safety and survival tips, and find out the locations and services available in gateway communities.

Integrating RICOH GPS cameras, Trimble GPS devices & ESRI ArcGIS

Over 200 petrified tree stumps were inventoried with geo-tagged photos and Trimble GPS units.  Monitoring will continue to record ongoing trespass and document damage in the Lund Petrified Forest in Northern Nevada.

Objectives
Fossil forests with petrified trees still standing or lying in place are rare.  This project describes mapping support offered by BLM to assist Paleobotanist Diane Erwin and her UC Berkeley team to inventory over 200 petrified tree stumps and monitor damage within the Lund Petrified Forest in northern Nevada.  The project aims to develop a plan to preserve the trees for research and recreation by developing means to minimize the effects of freeze/thaw weathering, uprooting of stumps from the overgrowth of vegetation, and unauthorized collecting

Chosen Tools & Their Benefits
ArcGIS, Trimble GPS and GPS-enabled photos were used to locate and photo document over 200 petrified tree stumps.

Real-time event monitoring with GPS-cameras, Trimble mapping & ESRI ArcGIS

This stipulation monitoring project for the Burning Man 2008 features the development of an integrated suite of geospatial tools for real-time monitoring of permit stipulations in this unreal (or is it surreal?) environment.

Special Recreation Permit process (SRP) and documents for Burning Man 

Objectives

The Burning Man event was first held on the Black Rock Desert in 1990 and has continued since annually. The combination art festival, social event, and experiment in community living starts the Monday before Labor Day and lasts 8 days. Since 1990, the event participation has increased from a few hundred participants to over 50,000 participants in 2010.  Permit fees paid to BLM are 7 digits.  In terms of both the number of users and fees, Burning Man is the largest permitted event on public lands for any US federal agency.  Given the nature of the event activities and the fees involved, it is not surprising that Burning Man commands much public visibility.  It is critical that BLM closely monitor and document compliance with the event permit.

Route inventory & assessment data analyzed with results and recommendations for travel management planning and the managing race  special recreation permits(SRPs)

The biggest challenge in inventorying motorcycle routes is the high level of riding skill that is needed to access these areas.  The project field staff was comprised of members of the racing community whom possess decades of knowledge and experience both riding and designing courses in Northern Nevada.  Routes were GPS-captured to ensure the accuracy of recorded locations and record trail conditions, area for rehabilitation and other assessment data that could not be obtained from maps or sensed remotely by plane or satellite.

Objectives

The team drew from its combined decades of experience in course design, race riding, soil and erosion control, land management GIS in making the recommendations to facilitate the management of special recreation permits (SRP) for races.  Collected field data builds upon and enhances existing travel route data from previous efforts dating back to 2005.  This dataset also supports the next route identification and designation steps in the travel management plan.

Familiar tools make it easy for the public to view data and submit comments for the travel management plan

Objective

Winnemucca BLM has devoted field staff to route inventories and assessments since 2005.   To date, 3,000 miles have been located by GPS and documented with gps-photos.  Inventory areas were prioritized by popular areas for recreational use, special recreation permits (SRPs) events and former lands bills proposals.  The Nightingale Special Recreation Management Area (nSRMA) will be the first area for which route inventory data will be published electronically. 

An interactive map to communicate route location proposals and facilitate the race permitting process

When only previous permitted route segments were to be considered for future race routes, an efficient method was needed for race organizers identify previous route segments to create new route proposals based on segments that have already passed environmental review.  The method also needed integrate with BLM's GIS sytem to compare those routes with reference background data for analysis and documentation.  The previous race routes dataset was originally created to identify general route locations and areas in the Winnemucca BLM district.  It has now been published as a KMZ file makes use of Google mapping tools.  This allows the exchange of race data and comments directly via an interactive map containing not only documented, approved routes but reference data essential to race organizers and BLM staff alike.  The electronic submission of routes for a Special Recreation Permit (SRP) is now reality.

Objectives

This dataset was initiated ten years ago, to describe general route locations and identify areas by which races would be permitted rather than specific linear routes.   While those programmatic EA efforts might again be revived, the dataset has found multiple purposes throughout the years.  GIS routes allow for the overlay of administrative (i.e. legal land descriptions, surface ownership) and resource (wildlife habitats, hydrology) data layers.  When new routes were to be compromised of already permitted segments, the dataset became invaluable.  Maps were printed, marked with ink and then re-digitized back into GIS.  Google mapping tools provides solutions that integrate both recreational and professional level GIS and GPS systems.  The electronic submission of prpposed routes will allow for the efficient 2-way communication of spatial data and ease the permitting process.

There are a number of technologies to choose from for the delivery of maps and spatial data. The 'best tool for the job' depends on the audience, the data, and the project goal.  There is no one right choice.  As technology progresses, even today's best choice might soon be surpassed by newer options and toys.

2005

The chosen technology to communicate spatial information was ESRI ArcReader.  To view the previous race route data, ArcReader had to be installed on the user desktop machine.  This proved to be a challenge to some.

2007

The data was republished in a newer format, GeoPDF which could be opened the commonly adopted Adobe Reader application.

2011

The data moved once again to keep pace with evolving technologies.
