Fixed a display bug that appeared in the Show Report of Last Computation window when the old map is georeferenced and the resulting scale is close to 1:1. Residuals for each point are now shown in the report window. Outliers longer than three times sigma 0 are marked with an asterisk. For affine-6 transformation, the root mean square of all residuals is now displayed: sqrt(((u*u)+(v*v)) / n) with u and v residuals in horizontal and vertical direction and n the number of points. This is the same value as displayed by ArcGIS in the Georeferencing dialog. When using an affine-6 transformation, the 'Report for Last Computation' showed wrong standard deviation for translation parameters and gave wrong direction for the second rotation angle. Fixed. Distortion grids along longitude / latitude lines can now be generated. To enable this feature, select degrees in the menu following the Fixed bugs in error message reporting wrong size of distortion grid. The maximum number of vertical or horizontal lines in a distortion grids is now 1000 (was previously 200). Fixed a bug in the 'Export Points ->, Linked Points of Old and New Map and Vectors in New Map' command: exported azimuth were wrong. Fixed. Many thanks to Prof. Peter Mesenburg for reporting this bug. Fixed a small error in the computation of the standard derivation of translation parameters of the Helmert transformation (value shown in the report window). This bug did not affect the graphical results or the computation of the scale and rotation of maps. Linked points are now displayed in a table instead of a simple text window. Points selected in the list are also selected in the maps and vice versa. Fixed a font issue that resulted in the 'Old Map Information' not being completely displayed on Windows operating systems. Improved report window: scale factors are inverted if smaller than 1, standard deviations indicated are labelled as such, improved layout. Fixed wrong computation of standard derivation of translation parameters in Helmert transformation (values shown in the report window). This bug did not affect the graphical results or the computation of the scale and rotation of maps. : OpenStreetMap is now the default reference map. There is no longer the need to scan a modern reference map for many areas. OpenStreetMap provides good enough reference information for many types of analyses. However, if OpenStreetMap is not of sufficient quality in the area of interest, a scanned map can still be used instead. Added the option to export linked points in pixel units for the old map (as defined by the old map image) and in meters for the reference map. Fixed bug that prevented project files from being loaded when the referenced image files of the old or new map had been moved to another folder. Added File - Export Points - Linked Points of Old and New Map and Vectors in New Map. This generates a file with 7 columns: Version 1.2.1 of MapAnalyst offers many new features. In combination, the new features allow you to comfortably analyze sections of a map by only using a selection of all control points. It's now possible to have multiple projects open at the same time. Each project opens in its own window, and is stored in its own document. Circles visualizing displacements of points are now proportional in area to the distance of displacement. In previous versions, the radius was proportional to the distance of displacement. Source.
