Keymap SDK C++ Edition
The Keymap SDK is
a set of C++ classes designed with the purpose of simplifying the development
process of GIS applications for programmers. It supports a wide range of GIS
features, include built-in GPS support, symbology and advanced road styles.
Unlike other GIS products which are usually shipped as ActiveX components,
Keymap SDK is a set of C++ classes that can be easily embedded into your
programs. Keymap SDK don't use MFC or any commercial GUI library in order to
achieve maximum portability and performance. Keymap SDK supports all Microsoft
platforms, include Windows CE, Pocket PC 2003, Windows Mobile 5, and Windows
Mobile 6. Same source code used for all platforms (99.9% code is shared, core
engine code is identical) so you can do development in PC, migration to mobile
platforms requires minimal effort.
Due to its unified programming interface, very small
memory footprint, user-friendly graphical interface, high performance and easy
portability, Keymap SDK is strongly believed to become a very useful tool for
GIS software developers.
One of most exciting features of Keymap SDK is an ability
to custom-draw everything. Developer can set any layer USER layer, and define
your functions to draw nodes, text, polylines, polygons etc. A Keymap layer can
be NORMAL, USER, ROAD, BUILDING or POI. Developer can change layer type on-the-fly by
calling one API method. Beside custom drawing of entire layer, developer can
draw his own objects over the map by processing WM_MAPVIEW_UPDATE message.
Drawing can be done using DisplayDevice, or conventional Win32 device context
HDC. This approach gives freedom to developer, so he can manipulate not only map
data, but customize map view according to business needs.
New indexing algorithm
Geo-spatial indexing is critical part for all GIS
systems. Overall system performance depends on many factors, however indexing
plays one of most important roles. We have implemented new indexing
algorithm, that's about 20% faster then known approaches. Keymap applications
can handle with very large GIS databases in limited devices like Pocket PC and
Windows Mobile devices.
Road and POI styles
SDK can render road data using user-defined color and styles according to
current scale. This feature allow users to create good looking map. High quality
of map output guarantied by advanced drawing algorithm with anti-alias enabled.
Optimized core engine avoids performance degradation during map rendering.
Styles are defined in very simple manner through graphics user interface:
If scale is <scale> and (Field#n = <data> or any
object) draw road with outline color <coloer> and width <width> and fill color
<color> and (label or pattern or annotation)
Beside road styles, POI styles also available. User can
use any images to draw node objects. POI styles are defined in same manner as
If scale is <scale> and (Field#n = <data> or
any object) draw node using image <file name>
Built-in GPS support
Reading and parsing GPS sentence seems to be very simple
task, however "do it right" not so easy. Keymap SDK has built-in field-proven
GPS reader and parser. The parser can read raw data directly from GPS port, and
can understand Microsoft GPS API. Simple, reliable and efficient GPS parser is
ready for your application.
Edit, undo and redo
Keymap SDK support editing map objects. User can add,
delete and change all kind of map objects (geo data, properties, metadata).
Developer can define any number of undo/ redo steps. Virtually Keymap SDK
supports unlimited undo/ redo. The only limitation is device memory.
Data protection (optional)
Fast and reliable AES encryption is available as an
option. Encryption operates transparently at disk access level. Encryption API
is extremely simple and easy to use.
The Keymap SDK C++ Edition can be installed in any
computer running Microsoft Windows
Microsoft Visual Studio 2005/2008 SP1 for both desktop, Pocket
PC and Windows Mobile development
Microsoft Visual Studio .NET or Microsoft Visual C++
6.0 for desktop development
eMbedded Visual C++ 4.0 for Pocket PC, Windows CE 4.2
and Windows CE 5.0
WTL 8.0 for demo version (Keymap SDK is GUI-independent and can be used with any GUI library)
During installation process, the installer will modify
Visual Studio environment settings, so you should have such privileges in the
computer Keymap SDK is being installed.
Keymap SDK-powered applications can run in desktop
computers, embedded PC, Pocket PC, Windows CE and Windows Mobile devices.
Currently Keymap SDK supports almost all Microsoft
Windows Server 2003
Windows CE 4.1, 4.2, 5.0
Pocket PC 2003
Windows Mobile 5
Windows Mobile 6
Supported development platforms:
Keymap SDK API and native SQL format is the same for all
