Two words about Kyrgyzstan

• Situated in Central Asia, having borders with
  Kazakhstan, Uzbekistan, Tajikistan and China
• Before 1991 was one of the Soviet Union
  republics.
• Total area of the country is 198.500 m2
• The population is about 5,2 million.
• Languages Russian (official), Kygryz (state
  language).

Land Registration Agency

• Local name Gosregister
• Responsible for land cadastre, rights
  registration and valuation
• Have about 49 regional offices countrywide.
• One central office, Land use Institute, Agency of
  cartography and geodesy.
• Supported by World Bank and Sida through
  Swedesurvey agency (Swedesurvey worked before
  2009)

5
Computerized registration system

• The name is Automated Registration System (ARS)
• Developed on MS SQL Server and MS Access (client)
• Currently widely used almost in all offices
• Has central database replicated from regional
  offices, providing external services to banks,
  real estate agencies and others

6
Core functions

• Applications processing
• Titles registration
• Owners registration
• Encumbrances and other restrictions registration
• Creation of new property objects in text mode.
• Amalgamation and division in text mode
• Printing certificates
• Different reports generation
• Archive

7
Cadastre software developmentBackground

• Before introduction cadastre software different
  standalone tools and packages were used. Like
  ESRI ArcEditor, MapInfo, AutoCAD, GeoDraw, etc.
• Operations with property objects were duplicated
  by ARS and graphical representation on the paper
  and digital maps
• No central storage for digital maps

8
Cadastre softwareFirst attempt

• In 2007 was initiated a creation of cadastre
  software in the scope of World Bank project.
• The following tools and formats were used
• ESRI ArcGIS Engine
• Visual C
• Shape files

9
Core functions

• Layers management with customization
• Map viewing
• Creation of new objects by coordinates
• Amalgamation, division by coordinates
• Property objects liquidation
• Printing forms of cadastre plan and land parcel
  binding
• Advanced search by property parameters

10
Disadvantages

• The only way to manage map objects is coordinates
• No graphical tools
• No central database and network environment
  support
• High cost per one sit (about 800)
• Proprietary code
• Difficult to extend

11
Failure reasons

• At the moment of the end of development
  activities there were no GPS receivers in piloted
  offices
• Lack of digital maps
• There were only 2 licenses of ArcGIS Engine in
  central office. No one wanted to buy licenses
  from the own budget
• Very high cost to introduce database and network
  support

12
Cadastre software Second attempt

• In 2008 Swedesurvey initiated development of the
  new cadastre software with extended capabilities
• From the beginning it was targeted for small
  regional offices
• There were created 2 versions in the scope of
  Swedesurvey project

13
Basic requirements

• Create a solution, based on Open Source
  components (free of charge)
• Introduce network database support as a central
  storage of digital maps
• Develop graphical tools to manage map objects
• Integrate with ARS database
• Move all cartographer functions from ARS to
  Cadastre software
• Process applications from ARS
• Extend different functions from previous release
• Add new functions

14
Components

• PostgreSQL
• PostGIS
• SharpMap
• GeoAPI.Net
• Proj.Net
• GDAL
• Visual C

15
Why Microsoft, not Java?

• Existing environment is built on Microsoft
  products including ARS and central database
• In the nearest 10 year Windows will not disappear
  from the client sits
• Server side could be ported on Unix box
• Hard to find Java programmer to work on
  government agency

16
Results

• Solution was successfully piloted in 2 regional
  offices
• It was taken a decision to renounce the use of
  commercial software and introduce open source
  solution in all offices gradually
• New requirements were prepared for the third
  version

17
Cadastre software(current release)

• The name is Cadastre for ARS
• A lot of improvements were done
• Development finished in November 2010
• Will be installed in 4 offices by the end of year

System architecture

• Client-server three-tier architecture with
  well-defined interfaces
• Business layer (middle) implemented as a
  web-service
• Modular nature of tiers
• Works over TCP or HTTP (HTTPS) protocols

21
Integration with ARS

• Integrated with ARS (main database) by Property
  code (identification number)
• Property objects are created in cadastre software
  and automatically replicated into ARS
• Information on owners, rights and restrictions is
  taken from ARS

22
Core functions

• Map layers management and customization
• Add, remove layers (raster, shape file,
  PostgreSQL)
• Customization of colors, fills, lines, labels and
  business objects binding
• Map viewing
• Simple georeferencing
• By World File
• By polygon on the map
• Applications processing
• Moving applications between departments
• Applications distribution among department staff

23
Core functions

• Spatial analysis
• Set of common spatial functions integrated with
  information from registration database (ARS).
  Type of owner, type of land, type of usage, cost,
  etc.
• Basic topology verification
• Export to shape file or raster formats
• Printing forms
• Cadastre plan
• Land parcel binding
• Free printing with customized parameters

24
Core functions

• Advanced search
• By map objects
• By property parameters
• By address
• By owners
• Property objects operations
• Creation
• Amalgamation
• Subdivision
• Liquidation
• Buffer
• Creation of buffer zones internal or external

25
Advanced graphical tools

• Rule
• Point
• Arc
• Polyline
• Polygon
• Closed polygon
• Internal polygon
• On the fly switching between polygon, polyline
  and arc
• Perpendicular

26
Advanced graphical tools

• Parallel
• Movement
• Rotation
• Vertex edit
• Amalgamation
• Subdivision
• Copying
• Length and angle
• Total station
• Linear intersection

Lessons learnt

• It is important to involve end users from the
  beginning, to get a clear vision about their
  needs. Dont stick on TORs
• It is vital to have services-oriented
  architecture giving you maximum of
  interoperability, flexibility, scaling and
  security control related to the business
  processes
• It could be necessary to have any of CAD programs
  to create cadastre plans and store them together
  with property objects
• The ideal solution couldnt be created from the
  first release
