Annual Meeting Coming! August 23rd
The Florida Region of ASPRS Annual Meeting will be taking place Friday, August 23rd, beginning at 9:00am. Where: Tradewinds Resort, St Petersburg, FL, Sabel Room Tentative Agenda: Registration is FREE! If you are intending on attending or presenting, please RSVP here if you have not already done so. Since our meeting is being hosted in concert with the Florida Surveying and Mapping Society – please consider registering for the FSMS Conference activities as well If you need hotel accommodations, please consider reserving a room at the Tradewinds Resort: Ortho Imagery: Pay or Play Free?
In the recent years of budgetary cutbacks and cost cutting measures, one of the common questions raised revolves around why a state or local agency such as the Property Appraiser, Police/Fire Department or Environmental Department should spend hundreds of thousands of dollars for imagery when there appears to be an abundance of freely available imagery on the “web”. This question has been asked of me on multiple occasions from multiple sources in my agency, as well as, from other agencies. Hence, this article is of relevance to discussions, perhaps, state-wide. The well written article by Mr. Kalinski highlights the advantages and disadvantages of using “Commercial Off-the-Shelf” (COTS) imagery available from Google, Bing, etc. The crux of the matter resolves to a few basic issues; (1) you get what you pay for, and (2) not all imagery is the same. In a table (reproduced below) Mr. Kalinski points to the availability of metadata, resolution, currency and cost as the major factors that should influence the end-users decision. He ends the article by reminding the end-user that there is no warrantee of usability with “free” imagery… caveat emptor! (my words)
This topic has arisen within the state, and in the Fall of 2012, several of the Water Management Districts and the Florida Department of Transportation engaged in an exercise to determine the positional accuracy of COTS imagery. I constructed a set of guidelines and we independently applied them to Google and Bing images for our respective Districts. In general, we used a photo identifiable, surveyed points that had been previously used for ortho-imagery horizontal accuracy testing to test the COTS images. While there is some variation, most likely resulting from different image years, the results were fairly consistent (and shown below).
In general, we found that Bing images, as viewed through a then-available free ESRI Map service, had greater horizontal accuracy than Google. In fact, Bing image horizontal accuracy is very close to the horizontal accuracy specification for state-wide 30cm ortho-imagery. So… as suggested by Mr. Kalinski, if we were interested in locating a favorite fishing spot, the Bing image would be great. However, if we are using the imagery in a court of law, we have a very different end-use. News from the Florida Student Advisory Council (FL-SAC)
Calling all students! Are you currently looking for an opportunity to get more involved and network with leaders in the Florida geospatial industry? If so, the perfect opportunity has arrived to be in on the ground floor of the ASPRS Florida Region Student Advisory Council (FL-SAC). The FL-SAC has been commissioned by Florida Region President, Brian Murphy, to provide all university and college students in the State of Florida and the Commonwealth of Puerto Rico with a venue to participate and organize geospatial activities. The initial proposed FL-SAC structure is similar to the national Student Advisory Council (SAC) of which I have had the pleasure of being a part of for the past 2 years. As the outgoing SAC Chair, I have had the opportunity to voice the opinions of ASPRS students at National ASPRS Board meetings, participate in national conferences as a student assistant, organize student mapping competitions, strengthen ASPRS student chapter relationships, share ASPRS student-related activities via our student blog, and compile employment opportunities for job seekers through the Virtual Career Expo (ASPRS login required). By connecting students from campuses across Florida and Puerto Rico, I look forward to replicating National SAC activities on the regional level through my FL-SAC position as the incoming Chair. These activities can include collaborating on a future GeoLeague Challenge team, forming a Student Map Competition team for the upcoming San Antonio conference, organizing an online technical meeting similar to this recent Eastern Great Lakes Region symposium, or creating a webinar series to share student research projects. Having attended many professional webinars and participated in numerous classes as part of the University of Florida’s distance education Geomatics program, I am comfortable with the video conferencing and virtual meeting space technology that will enable us to collaborate beyond our physical campuses. For those of us able to travel, I look forward to face to face meeting and networking opportunities such as the Florida Region ASPRS Annual Meeting in St. Pete Beach on August 23rd.
If you are interested in getting involved with the FLSAC in any capacity, please contact our ASPRS Florida Region faculty advisor, This e-mail address is being protected from spambots.

Six ASPRS Florida Region students from the University of Florida traveled to the week-long event in Fayetteville, North Carolina. Fun Facts About Our Great State
• Florida is not the southernmost state in the United States. Hawaii is farther south.
• Miami installed the first bank automated teller machine especially for rollerbladers. • Florida is the only state that has 2 rivers both with the same name. There is a Withlacoochee in north central Florida (Madison County) and a Withlacoochee in central Florida. They have nothing in common except the name. • Citizens of Okeechobee County Florida own more pick-up trucks per capita than anywhere else in the country with an average of 3.2 trucks per family. Okeechobee County also has a larger population of cows than it does people. • Once a year, thousands of Floridians stand at the state line and toss dead fish into Alabama. It's the annual Mullet Toss hosted by Flora-Bama Beach Bar in Pensacola. Creation of the The Florida Region Student Advisory Committee (FL-SAC)
On April 22nd the Florida Region created a committee called “The Florida Region Student Advisory Committee (FL-SAC).” This committee will help serve the entire Student Member population, and will also serve as an ASPRS Student Chapter resource. Through the FL-SAC, we hope to give every student member of ASPRS in the Florida Region to be able to get involved in some meaningful way, whether it be at a Chapter level, Region level, or National level.
We have asked two individuals to head this Committee: Adam Benjamin, as the Chair; and Dr. Amr Abd-Alrahman, Faculty Advisor; and will grant them authority for developing additional roles in the committee.
Adam Benjamin is a current PhD student of Geomatics from UF out of Plant City. He is currently concluding his role as Chair of the national Student Advisory Council this summer. My intent is to benefit from Adam’s experiences and leadership from the National ASPRS SAC, to help model the FL-SAC after the national SAC, and develop a self-sustainable Student program at a Regional level. Dr. Amr Abd-Alrahman is also from the University of Florida’s Geomatics program and has become increasingly involved at a National level as well. Amr will be helping Adam
Our goals for this committee are the following:
• Assisting in the hosting of regular FL-SAC teleconference calls • Developing a Self-Sustainable Student-Run organization • Developing a reporting mechanism for Student Chapters to Report to the Region, via the FL-SAC • Encouraging faculty from other Universities, Departments and Disciplines to get involved with the FL-SAC and their Chapters • Encouraging chapter involvement with the national GeoLeague competition • Assisting with the recruitment of new Students and Faculty • Developing a series of Paper Presentations by the Florida Region students • Helping form new Chapters • Helping Sustain existing chapters Adam and Amr held the first meeting of the FL-SAC on May 13th, 2013, attended by a combination of students, board members, and faculty members. If you are interested in helping become involved with the FL-SAC or know anyone who might be interested, please have them contact Adam, Amr and myself. The 2013 Board of DirectorsPresident, Brian E.

• May 20, 1970 Florida lawmakers passed and sent to the Governor a bill adopting the moonstone as the official state gem. Ironically, the moonstone is not found naturally in Florida...nor was it found on the moon.
