Add-ins can be used to provide end-users with easier access to existing software functions; to add new capabilities to the GIS engine; or to create hooks to your own applications. You can download any of the following add-ins to extend the capabilities of TransCAD or Maptitude version 4.0 or higher.
| NAME | DESCRIPTION |
| ADD CIRCLE | This toolbox creates a circle of a user specified diameter at a clicked point. |
| BATCH MAPS | Prints a batch of maps based on chosen map features. |
| CLICK COORDINATE DMS | This toolbox displays a clicked point in degree/minute/second format. |
| EXPORT TO CSV | This add-in enhances CSV file export to include field headings. |
| GREAT CIRCLE LINE | This toolbox generates a great circle line annotation between two points on a map. |
| IMPORT BNG SHAPEFILES | This resource file demonstrates how to batch import all the Shapefiles in a directory where all such files have a common coordinate system (in this case the common coordinate system is the British National Grid). |
| MAP INVENTORY | This macro creates an inventory for each map open in the current workspace. Details for each geographic file are provided. |
| MARK DUPLICATES | This macro marks as duplicates any records that have the same value in a field as the first record with that value. |
| MARKER MANAGER | The add-in lets you manage marker files.You can open an existing marker file, save chosen markers to a new file, delete markers from the open file, and append markers to an existing file. This add-in allows you to share your markers with others. |
| POLYGON OVERLAY | Overlay two area layers and create a geographic file of the intersected areas with a table of the percents of overlap. |
| REPROJECT USA | The Reproject USA Add-In reprojects and edits a geographic area layer that has a global extent. The result is a map layer with the USA on the central meridian. |
| STYLE EDITORS | The style editors are toolboxes for working with colors, fill styles, and line styles. |
| STYLE SAMPLER | This add-in shows you how the various Maptitude colors, area fills, line types and symbol fonts look on your printer or plotter. |
| TRAVELOGUE | This add-in lets you click on a map feature and view or print a set of pictures for the feature. |
| WRITE FORMULA | This macro writes a text file with a list of formula fields and their expressions for the current layer. |
| ZERO TO NULL | This macro finds values of zero in numeric fields and changes them to null. It illustrates how to read records in a dataview, get values for some or all of the fields in a record, check and change values in fields, and write updated values back to the fields. |
| The following examples illustrate various GISDK functions and are meant to help you program your own add-ins. | |
| NAME | DESCRIPTION |
| ADD ANNOTATIONS | This macro demonstrates use of the AddAnnotation() macro function. |
| CREATE FIGURE | This macro demonstrates use of the CreateFigure() macro function which is used to create charts (line, scatter, bar, pie, etc.). |
| DBOX SAMPLER | This macro displays a dialog box (dbox_sampler) that illustrates all of the user interface items that can be shown in a dialog box. Each item is displayed, along with the GISDK code used to create it. |
| ERROR HANDLING | This toolbox demonstrates different error types and ways to handle errors. |
| TIMER ZOOM | This toolbox illustrates use of the "timer" functions, used to execute a macro on a timed basis. |
| ZOOM TOOLBOX | This add-in illustrates how to use toolboxes, interface tools, and functions. |
