TRANSFORM FOR WINDOWS FEATURE LIST

• Transform presents a full featured Windows application which exposes the ubiquitous windows user interface along with the typical windows feature set, including tool tips, context menus, printing, etc.
• Each saved project is a collection of all the different coordinate systems and associated transformation parameters for a particular job. Coordinate systems can be defined from any number of sources, such a field survey, highway layout, subdivision or deed as long as each point can be uniquely identified within that system by a alphanumeric point number.
• Transform will optionally reload the last opened (used) project on startup along with all the user and system settings associated therewith.
• Using the Most Recently Used (MRU) list in the file menu, you can quickly access/open the last eight projects that were saved.
• Coordinate point numbers are unique to a coordinate system and therefore the same point number can be used in each coordinate system to describe a different coordinate position.
• Point numbers can be comprised of both alpha and numeric characters, up to a maximum of nine characters in length.
• Points can be cloned from one system to another. The cloned point’s coordinates are updated dynamically to reflect any change made to the point’s parent as a result of the system’s coordinates changing via a user transformation or least squares transformation.
• Inverses can be made at any time between two defined points within a single system or across multiple systems using either the original or modified coordinates of either system so that comparisons can be made with CAD drawings, etc.
• Coordinate points can be imported from any comma delimited ASCII file in meters or feet and you can import either transformed coordinates or original coordinates. Choose from any of six different import fields: Point, North, East, Elev., Description, and System. (note, space delimited files are not allowed, since a point’s description can contain spaces)
• Coordinate points can be exported to any comma delimited ASCII file in meters, feet, transformed coordinates or original coordinates. The user can also choose to modify point numbers on export. Choose from six different export fields: Point, North, East, Elevation, Description, and System.
• A small but time saving feature is that the file open and save as well as the import and export wizards remember the last folder that was used to access a file and will start in that folder. Additionally, Transform recognizes long file names and network paths.
• The Point's identifier, coordinates and description can be edited or deleted from within the application’s environment.
• New coordinate positions can be entered within the application by supplying either a transformed coordinate value or an original coordinate value. Coordinate positions can also be edited with the application. Alternatively, you always have the option of defining groups of points by using the Import wizard. If the point number for a given system was already defined, you will be given the option to skip or overwrite the point and to skip or overwrite all points.
• Transform for Windows displays either the normal (68%) probability statistics, or the modified 90%, 95% and 99% probability statistics with regard to rotation error, scaling error, translation error and transformed point error (special case error ellipse).
• Each point in the transformed system will have its error ellipse computed. An error ellipse, in this context, is an indication of the reliability of each point in the transformed system. A transformation error ellipse will always result in a circle and therefore are presented as an error radius.
• Transformations can be performed using subjective weights for each linked point pairs. The weight is derived from a user supplied variance for each coordinate pair. The variance of a point pair, in this context, is the user supplied estimated accuracy of the point’s North & East coordinates. Variance values can range from 0.001 feet to 10 feet, but cannot be zero.
• When defining new point pairs, once you can change the point’s default variance, that variance will automatically be used for each additional/subsequent paired point you define.
• Transformation point pairs are defined by linking a coordinate point in the system to be transformed with a coordinate point in a fixed target system. By default, Transform will sort the list of target system points according to their proximity to the subject system point, placing the highest probability point matches at the top of the dropdown list.
• The description for subject points and target points is displayed in a floating Tool Tip when the mouse pointer is held over the point number so that you can check to make sure the selected point is of the proper type, such as an iron pipe, bound point, etc. • Floating Tool Tips are used to explain many of the fields displayed by Transform. Just hold the mouse over a button, dropdown list, text box, grid element, etc. to see additional information about the item.
• Transformation results are displayed dynamically, based upon user actions, such as clicking a link box or changing a point’s variance, meaning that all aspects of the transformation are updated and display as soon as any parameter is changed by the user. Note: no transformation is performed until at least two check boxes are set. Note: a two point transformation creates a unique solution equivalent to rotating and scaling the system based upon one inverse in the target system. Therefore, a two point transformation does not result in any statistical output.
• The inverse error is displayed for all paired points, whether or not a point has its link box checked for inclusion in the transformation computation. Paired points without a checked box do not contribute to the transformation.
• Point lists can be filtered in a variety of ways so that only certain points are listed in a given view. Lists can be filtered by point number range, by point descriptions each of which can contain wild cards, and the transformation view can also be filtered to show only paired points.
• The columns in each view’s table can be sorted in ascending or descending order just by double clicking the column’s header. You can also drag and drop columns to move them to different positions. Columns can also be resized or hidden simply by dragging the divider between headings.
• Print and Preview point lists and transformations. You can also view, edit and print either transformed coordinates or original coordinates. Hide columns that you don’t want to view or print.
• Transform allows you to work with a variety of different data formats. Directions can be bearings or azimuths displayed in degrees or gons/mills. Input of directions can take on a number of different formats as well. Distances can be in either metric or U.S. Survey Foot units of measurement. NOTE: The use of Imperial or English units of measure are not mentioned, since they reference a different length of foot.
• When entering new data, you can supply any number of decimal places for accuracy and Transform will capture the digits, whether or not those digits will be displayed. The user can configure how many decimal places Transform will display for output of coordinates, distances, and directions.
• Enter angle and directions in quadrant format, prefix and suffix format or azimuth format with single radix or multiple radix formats. • The scaling associated with any transformation can be rolled back so that the resulting transformation has no scaling (see the discussion page on scaling)
• Easily rotate the meridian of the fixed or target system to match that of the subject system being transformed and designate a base point for the rotation.
• Each system can be manually translated by choosing a point number and then supplying the desired or target coordinates, including elevation.
• Each system can be manually rotated and/or scaled by providing the target bearing and distance between two points in that system or by supplying the actual rotation angle and scaling. Note: the Field Survey system cannot be scaled.
• Print transformation reports with tables and values formatted exactly the way they display on the screen. Show or hid columns and rows in a transformation table by right clicking in the table and choosing what you want to be displayed. Transform will print only the information you choose to show on the screen.
