OpenGeoDa 1.0.1 Release Notes Changes since 1.0: - Fixed a bug in Scatter Plot where plot points were difficult to see. Changes since 0.9.9.15: - Bug in Arc Distance option for Theshold Distances fixed. Changes since 0.9.9.14: - Major speedup to LISA and Getis-Ord Gi-Statistics. When a multi-core processor is detected, pseudo p-val calculations are split up amongst the cores. On some machines a 20x speedup is possible. - Ability to load, edit and perform calculations on a DBF without the SHP / SHX files from the File menu. - Table code totally rewritten with many new features. - Table: can drag columns to reorder and new column order remembered after saving Table - Table: Edit Field Properties dialog added. Can rename fields and change all field properties such as field width and number of displayed decimals - Table: Field Calculation: Can generate Gaussian Normal distribution - Table: Field Calculation: Can randomly shuffle order of any numerical field - Table: Replaced Range dialog with new more powerful Selection Dialog - Table: undefined / invalid numbers appear as blank entries. For example, square root of negative numbers appear as blanks rather than zeros. Use new Selection Dialog to find all undefined numbers - Merge Table Dialog: more robust and powerful. Automatically identifies and eliminates duplicate field names. - Regression: fixed a problem where invalid results could occur after adding a new field to Table without saving first. - Weights Creation: can manually edit distance field. - Many small bug fixes and stability improvements. Changes since 0.9.9.13: - Added ability to enter in constants directly in Field Calculations Changes since 0.9.9.11: - Getis & Ord local G statistics added. A new toolbar icon has been added and a new menu option under space. Changes since 0.9.9.10: - "Select All... Cores, Neighbors of Cores, Cores and Neighbors" added to LISA maps as a right-click-popup menu option to aid in LISA analysis. - "Add Neighbors To Selection" right-click-popup menu option added to LISA maps and to Table (when a weights file has been loaded). - Added limited support for DBF date field. Dates are treated like an integer, but are limited to 8 digits long and must be in the format YYYYMMDD. For example Jan 31, 2011 will appear as 20110131. - Tested on Ubuntu 9, 10, and 11 for both 32-bit and 64-bit. Changes since 0.9.9.9: - An unlimited number of DBF fields is now supported. Note that some older DBF programs only support a limited number of fields, but there appears to be no standard for what is acceptable. - Fixed an issue where the number of outliers calculated by Box Map, Box Plot, and Cartogram map would sometimes slightly disagree. - Fixed an issue where program would hang when a Moran's Scatter Plot for a weights file containing isolates is displayed an isolates are selected in another view. Changes since 0.9.9.8: - Moran's I, LISA maps and LISA box plot now correctly handle weights files with neighborless observations. Notice that a new category has been added in LISA maps for neighborless observations. Neighborless observations are completely excluded from Moran's I calculations and from LISA box plot. Changes since 0.9.9.7: - The loading time for point-data shapefiles significantly reduced. - it is now possible to open a weights file that was created from a different shp file than the shp file that is currently opened: only the number of observations and the id variable in current dbf file need to match. - Re-added variable and weighs selection toolbar icons - Increased precision of Shp to Bnd export to 10 digits after the decimal. OpenGeoDa 0.9.9.7 Release Notes Changes since 0.9.9.6: - LISA maps a now fully synchronized again - Newly created weights files are now loaded into OpenGeoDa automatically. - Weights can now be easily selected and created everywhere that they are needed. - New fields can be added to the table from within the Field Calculation dialog. Changes since 0.9.9.5: - Fixed an issue with mouse selection on OSX where a selection rectangle would automatically start in the upper-left-hand corner when mouse focus first moved between two windows. - Added some white-space between Condition Plot cells for maps. - Weights Characteristics Histogram: when neighborless observations (isolates) are detected, a button appears in the histogram for selecting all neighborless observations. - Added observation counts to cell windows in all Condition Plots. Changes since 0.9.9.4: - Histogram was sometimes treating values as integers when it should have been treating them as general floats. - The labels in the "Save Regression Results" were mixed up. This has been resolved. - In conditional plot, the X/Y axis for each scatterplot cell was did not match the labeling. - Box Plot graphics are improved. The median is displayed clearly as an orange line, and the mean is a green dot. Observation selection behavior is also fixed. - Conditional Box Plot view now works properly. Changes since 0.9.9.3: - Fixed a bug in Regression where values for R^2 and lambda/rho were invalid when isolates present in the weights file. - Reenabled ability to change order of variables in PCP map by dragging on the control circles. Dragging behavior changed so that a dragged variable will be inserted between the two variables that it is dragged to (ie, the user should drag the control line between control lines, rather then on top of another control line). - Weights Histogram now appears the same as in Legacy. it is once again very easy to see if there are any isolates in the weights file. Changes since 0.9.9.2: - Fixed a serious problem where Spatial Lag Model and Spatial Error regression models would give bad results when opening the Regression dialog directly from a DBF file. This bug only existed in the 0.9.9.1 and 0.9.9.2 releases. Changes since 0.9.9.1: - Default number of digits after the decimal for new floating point Table entries is nine rather than four. Changes since 0.9.9.0: - Fixed a bug where algorithms that use a spatial lag, such as Moran's I, would produce incorrect results for GWT weights files. - Lisa clusters are now updated when the significance level is changed: non-significant clusters are now categorized correctly when save to the Table. Changes since 0.9.8.19: - Reduced size of toolbar to less than 800 pixels wide. Thematic Map toolbar icons have been consolidated into a single icon with a drop-down menu. Changes since 0.9.8.18: - Last-used variable settings remembered - non-significant LISA categories now recorded as 0 when saving to the Table. - Table shows all decimal places for floating point numbers according to the precision field in the DBF file. - Fixed a problem where floating point numbers in a DBF file would get truncated when OpenGeoDa was running on a computer that uses "," as a decimal separator. - When importing data from a txt file, OpenGeoDa defaults to 9 digits of precision after the decimal place in the DBF file. Changes since 0.9.8.17: - Restored fast loading times for Table and Map - Fixed a potential crash in Shape to Boundary conversion Changes since 0.9.8.16: - Improved the appearance of map in Conditional Plot - Options to change the colors in Map Movies now appear in the Options menu for the Map Movie. - Fixed an issue with Copy to Clipboard and Save As - Progress Bars added for shp file loading and Regression - Fixed bugs in Quantile map and improved so that number of available Quantiles is limited to number of different values in variable or nine, whichever is less. - Can now use GWT for Rate calculation in Table - Miscellaneous smaller bug fixes. Changes since 0.9.8.15: - Ability to specify float, int, or string data types when adding a new column to the table. - Fixed an issue with panning and zooming introduced in release 0.9.8.15 - Other minor bug fixes and error message updates. Changes since 0.9.8.14: - Not much has changed functionality-wise, but there have been a number of bug fixes and we are building against the wxWidgets 2.9.1 platform. This alpha release is now always recommended over Legacy Geoda. - Major improvements in Linux. There is no longer any drawing artifacts left on the screen. - Flicker removed from Windows. - Ability added to not draw polygon outlines. This helps greatly when viewing maps with many regions. Look for this new option under the Color submenu of the Options menu on any map. - Huge speed improvements during brushing operations when large maps are visible. Brushing is now much faster than in Legacy GeoDa. Changes since 0.9.8.13: - A 'Unique / Key ID Variable' is no longer needed when opening up a SHP file. In the Weights Creation dialog, there is now an easy way to directly add a new ID Variable to the DBF file directly if needed. It is no longer possible to create a weights file without specifying an ID Variable. - Weights File Creation dialog now opens the current project shape file by default. - Select Weightss dialog now opens up to the same directory as the currently open shape file. Changes since 0.9.8.12: - Re-enabled the ability to choose a character field from the DBF file as a key variable upon opening a shape file. At the moment, character fields are not offered as an option in the weights creation dialog. Use as a workaround if needed. Changes since 0.9.8.11: - Table 'Move Selected to Top' option only does something when at least one observation is selected. - A widespread issue on Mac where parts of various images where being duplicated by being slightly shifted upwards has been solved. Changes since 0.9.8.10: - It is now possible to choose between Arc Distance / Euclidean Distance and Center Points / Mean Centers for all weights creation options that require distance between polygon / point centers. - Arc distance calculation corrected: input is degrees of lat/long and output is arc distance in miles with the assumption that earth is a perfect sphere with a radius of 3959 miles. - 'Central Points' labels changed to 'Mean Center'. The mean center calculation was previously incorrect. Also note that legacy GeoDa incorrectly calls mean centers 'centroids'. OpenGeoDa also offers centroids and these are now calculated correctly as the center of gravity.. - All weights creation functionality has been verified to be correct. Changes since 0.9.8.9: - Solved an issue where Bivariate Map Movie would sometimes crash. - Bivariate Equal Interval Map no longer crashes. - Shape file to Boundary conversion crash on Windows is fixed. - Shape File from ASCII import fixed. - Table "Save to Shape File as ..." menu item working again. - Data Export: Centroids/Mean Centers no longer results in an occasional crash. - Shape File Creation: polygons from boundary now works. Changes since 0.9.8.8: - Hinge = 3.0 theme now works for various map smoothing options - Map themes are disabled for "Excess Risk" smoothing option - Labels for X, Y, and Z axes now appear in the 3D Control panel window (not in the 3D plot itself). Previously the user had to remember which axis was which. - Check-marks now accurately reflect the current chosen Map theme and smoothing function. - The title for the main tool-bar window now changes to indicate which window is currently active. - Labels for various Map windows (title and legend) have been corrected. - Various bugs fixed to improved Table operation stability. Many operations that would add a new column to the Table caused the program to crash previously. - Weight-create toolbar item is always enabled. - Restored Tools > Weights > Open and Properties menu options. - A problem where shape files generated by OpenGeoDa could not be read by other GIS programs has been resolved. - When opening a shape file, only columns of type integer are presented to the user as possible unique polygon identifiers. Changes since 0.9.8.7: - New image output formats: The "Save Image As" dialog now has options for BMP, PNG and PS. The PS (PostScript) format is the default and this outputs a vector-graphics version. This file can be easily converted to a PDF file with various free programs. - Improved stability: several memory-leaks discovered and closed. - Only SHP file name is displayed in the map title and legend rather than the full-path name and name with extension, respectively. - First releases for Linux! Download either 32-bit or 64-bit as appropriate. The 64-bit version is less tested and is more prone to stability issues at this time.
