2.4 Software components 
Software solution is based on two software components — 
MapWorldWide and Cadastar World Wide. First of them is part 
of the MapSoft 2000 software system and it represents Web 
Map Server which communicates with client according to 
OpenGIS/TC211 standard (WMS  ver..0) The other 
component provide link to cadastral database (land cadastre or 
real estate cadastre database). System is designed and 
developed as n-tier application. MapSoft 2000 is used as spatial 
database server and applicative services are written by using 
ASP. Together with software applications that provide user 
administration and statistical analysis of system usage, the 
whole system is a complete solution that provides simple 
system administration and usage just by using simple web 
browser on client side.

2.4.1 MapSoft 2000 Server 
MapSoft 2000 Server is developed as ActiveX EXE out-of- 
process automation server. MapSoft 2000 application has been 
developed by using Visual Microsoft software development 
tools. MFC class library, as industry standard, has been used 
intensively. Application has been based on Document/View 
architecture. This architecture and fine support to development 
of ActiveX EXE provided by Microsoft's development tools 
enabled relatively straightforward development of Active EXE 
server functionality for MapSoft (Figure 4). COM interface has 
been built for MapSoft's Document object. This enabled access 
to MapSoft's functions from outside, i.e. from other software 
applications.

All necessary functions were developed in order to provide the 
whole solution. The most important functions are the following: 
OpenWorkspace, SetActive WorkspaceProject, CloseWorkspace, 
GetNumberOfProjects, GetProjectExtent, GetProjectName, 
GetDefaultProject, SetZoomWindow (set active windows 
coordinates), GetZoomWindow, | CreateZoomlmage | (creates 
image file for current window), IsDocumentReady, WhatIsThis 
(retums object from database on specified location), 
WherelsThis (returns object from database with specified 1D 
Close (closes server connection for specified project). 
2.4.2 Link to DGP - MapWorldWide 
W3Map 
Applications W3Map.asp W3Map.dll make up application 
server (IIS application). Application server's task is to ‘listen’ to 
demands of Internet users, to process these demands and to 
forward them to Data Server (MapSoft 2000 Server). Also it 
has to process received answer from Data Server and to send it 
back to the Internet user. W3Map implements all three 
interfaces specified for Web Map Server: 
e  Capabilties (GetCapabilties) 
e. Map (GetMap) 
e Featurelnfo (GetFeaturelnfo) 
MapWorldWide provides information to the user about all 
available projects (Capabilties). Function Map implements all 
mandatory parameters specified by OGC Web Map Server 
specifications. 
W3Trigger (Figure 6) is component (ActiveX (DLL) responsible 
for starting Web Map server (MapWorldWide) via Internet.

W3Catalog 
W3Catalog (Figure 7) is a component (ActiveX EXE server) 
that enables administration and management with projects. Any 
project can be active or passive, and all the services could be 
stopped or activated by using this component (Start/Stop).
