TransCAD includes the Geographic Information System Developer’s Kit
(GISDKTM). GISDK gives you the tools that you need to create a wide
variety of products for delivering mapping and geographic analysis
capabilities to your customers. Over 700 functions can be called from
Caliper Script, a complete programming language for designing menus and
dialog boxes (including toolbars and toolboxes) and for writing macros.
The Caliper Script code is stored in resource files that you can edit
with your favorite text editor. You can develop:
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 4.0 or higher
(except as noted).

NAME |
DESCRIPTION |
|
ADD CIRCLE |
This toolbox
creates a circle of a user specified diameter at a clicked point. |
|
BATCH MAPS |
This add-in
prints a batch of maps based on chosen map features. |
|
CLICK COORDINATE DMS |
This toolbox
displays a clicked point in degree/minute/second format. |
|
DOWNLOAD FREE LAYERS* |
This add-in provides easy access to
no-cost web-based data sources. |
|
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 |
This 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 |
This add-in
overlays two area layers and create a geographic file of the intersected
areas with a table of the percents of overlap. |
|
REPROJECT USA |
This 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 |
This toolbox
lets you create custom line styles, colors, and fill 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. |
|

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. |
