Components > Miscellaneous > GIS

By Leonid Schavelev.

Shareware 07 Mar 2003


The most natural way to show territorial data is geographical map. Geoinformation systems (GIS) perform this function, but there are many tasks where these powerful tools are excessive. If you want to make visual representation of data for users of your programs, APMap is exactly what you need.

APMap is not just a simple GIS, but a component library for reflecting data on geographical maps and schemes in your programs. APMap automatically paints objects of your map patterns in different colors associated with data for corresponding territories. There are several methods of assigning colors to map objects; you may select necessary method and set its properties in run-time and in design-time. Map patterns (multilayer vector-based drawings) may be edited by APMap Editor utility (DXF import supported); you may load them from files in your programs, or directly include them into applications.

Properties of layers and graphic objects (visibility, color, text etc.) may be changed in run-time too. APMap contains native Delphi component, that may be compiled into your programs and don't need external files (dll, ocx etc.).

ODBF is a component library for quick and easy access to dBase tables. IDAPI and ODBC are not required. No DLLs - only your program and your database.
