You may find it useful to print this page out first so that you can follow along with the directions. The following checklist is for Penn State students who are registered for classes in which this text, and associated quizzes and projects in the ANGEL course management system, have been assigned. This chapter explores the technologies and procedures used to produce positional data, and the factors that determine its quality. Resolution and precision are two aspects of data quality. In practice, positions occupy 2- or 3-dimensional areas as a result of the limited resolution of measurement technologies and the limited precision of location coordinates. In theory, a single position is a “0-dimensional” feature: an infinitesimally small point from which 1-dimensional, 2-dimensional, and 3-dimensional features (lines, areas, and volumes) are formed. A property boundary, for example, is made up of a set of positions connected by line segments.
Like the letters that make up these words, positions are the building blocks from which features are constructed. Positions, then, are a fundamental element of geographic data. We defined “feature” as a set of positions that specifies the location and extent of an entity. Post-Processed Differential CorrectionĪs you recall from Chapter 1, geographic data represent spatial locations and non-spatial attributes measured at certain times. USE TRILATERATION TO DETERMINE A CONTROL POINT LOCATION.With a long and successful history of developing photogrammetric and mapping solutions, Cardinal Systems continues to provide the most powerful, pragmatic mapping tools available today.\( \newcommand\) Working with Orrin at NASA during the Space Shuttle program has given me insight into the possibilities that lie ahead.” Mike Kitaif, Cardinal’s Software Development Manager said, “Orrin’s deep knowledge and experience in theoretical and practical photogrammetry and remote sensing allows us to broaden our photogrammetric and LiDAR software development focus. He also completed a Master’s degree in Civil Engineering with an Emphasis in Photogrammetry from the same institution. He earned a Bachelor’s degree, graduating Summa Cum Laude from the Geomatics Engineering program at California State University, Fresno.
He was specifically honored for his work in creating “the largest… and the most accurately placed DEMs ever produced of the lunar surface”, and for programing geometric camera models for several space based line scan sensors-including the Apollo panoramic camera and the Japanese Kaguya multi-band imager. While with the USGS his focus was in remote sensing, cartography and computer related development. Thomas worked at the Johnson Space Center using photogrammetry to support the manned space flight programs-earning several honors for his Space Shuttle and International Space Station mission support. His experience includes working with NASA’s Image Science and Analysis Group and with the USGS Astrogeology Group. Thomas brings a wealth of knowledge in numerous areas including high-level Mathematics, Industrial and Aerospace Photogrammetry, Cartography, Land Surveying and Computer Programming to the Cardinal team. Flagler Beach, Florida, September 2012 – Cardinal Systems, LLC, the provider of the Vr Mapping suite of products, is pleased to announce that Orrin Thomas has joined the firm in the position of Software Engineer.
