    16TH ANNUAL OKSCAUG CONFERENCE TUESDAY, SEPTEMBER 24, 2013 GIS: RETURN ON INVESTMENT The OKSCAUG Steering Committee Welcomes you to the 16th Annual OKSCAUG Conference! On behalf of the 2013 Oklahoma SCAUG Steering Committee we cordially welcome you to the 16th Annual OKSCAUG Conference. With ever increasing pressure to do more with less, GIS provides an excellent resource to make better decisions faster and more accurately than ever before. Oklahoma is fortunate to have such a diverse yet cohesive GIS community, but how can we best focus on what the GIS professional needs? How can the GIS community benefit from the resources we have available? These questions, as well as a conversation in the rotunda at GIS Day at the Capitol this year, fostered the concept of Return on Investment as this year’s theme. Whether you are making a full week of the workshops, conference, & training or simply attending the main conference, we encourage you to continue to be an integral part of this network. Visit with old friends, and please make a special point to establish some “new” old friends for upcoming years. This year OKSCAUG attempted to incorporate as much professionally diverse content as possible into Oklahoma’s single largest annual GIS conference. Please share your opinions throughout the day regarding your experiences at the conference and with OKSCAUG in general. We welcome your input. OKSCAUG hopes to be the instrument that continues to help you sharpen your professional edge. 2 Platinum Sponsor Gold Sponsor 3 Silver Sponsors 4 Table of Contents

  • Search and Discovery Through Human Computation
    Search and Discovery Through Human Computation Albert Yu-Min Lin , Andrew Huynh , Luke Barrington , and Gert Lanckriet Introduction Machines are good at handling huge amounts of data, but they lack the fl exibility and sensitivity of human perception when making decisions or observations. To under- stand human perception, we look toward what defi nes being human. To sense, observe, and make sense of the world around us, we combine our biological recep- tors (eyes, ears, etc.) with our cognitive faculties (memory, emotion, etc.). But the memory banks that we pull from to create comparative reasonings are unique from individual to individual. Thus, we each see things in slightly different ways, i.e. what A. Y.M.

This is an important achievement for GRSS since it has never had a publication in the magazine format. The magazine will provide a new venue to publish high quality technical articles that by their very nature do not find a home in journals requiring scientific innovation but that provide relevant information to scientists, engineers, end-users, and students who interact in different ways with the geoscience and remote sensing disciplines. The magazine will publish tutorial papers and technical papers on geoscience and remote sensing topics, as well as papers that describe relevant applications of and projects based on topics addressed by our society. The magazine will also publish columns on: — New satellite missions — Standard remote sensing data sets — Education in remote sensing — Women in geoscience and remote sensing — Industrial profiles — University profiles — GRSS Technical Committee activities — GRSS Chapter activities — Conferences and workshops. The new magazine is published in with an appealing layout, and its articles will be included with an electronic format in the IEEE Xplore online archive. The magazine content is freely available to GRSS members.
