CE 603 Homework 1 Passpoint Selection and Measurement

• individual assignments: row 1: chivoiu, row 2 corsetti, row 3: fu & gungor, row 4: puatana & raj, row 5: song, row 6: wonnacott
• select passpoints in the pattern described in the course notes. they should be well defined (when zoomed in for measurement), and, ideally, in the "open", away from obstruction. you want an ideal point in an ideal location. if you cannot have both, then it is better to move away from the desired location, and still have a good point. if you cannot find a point anywhere near the desired location, then forget that one! (i.e. water bodies are famous places to avoid for pass points)
• make a report with the following entry for each point: point name (follow convention), photos on which it can be found, a zoomed in image patch showing point in detail (from one full-res image), a text description of the point.
• a set of hardcopy prints will be kept in room g144. use the red marker to mark a circle around each occurrence of the point.
• measure the pixel coordinates of the points (using photoshop, for example). create one text file with one line per measurement, "point_name photo_name row column". use "ph1_4" for photo names, and "p2_6" for passpoint names.
• due friday 24 january. hand in the report. email me the file.
• data is found on \\geomatics\data\bethel\ce603. there are two directories: block and blocksm. block contains the full-res images (appx 180Mb per image), blocksm contains a downsampled version (1 Mb each) of the photos. note: from a pucc/itap machine you may need full pathname for the share: \\geomatics.ecn.purdue.edu\data\bethel, and for login you need ECN\login.
