Alexander Solovov

Solution developer

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)

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

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

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

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

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

� 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

Disadvantages

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

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

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

� PostgreSQL

� PostGIS

� SharpMap

� GeoAPI.Net

� Proj.Net

� GDAL

� Visual C#

Components

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

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

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

Main window

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

Architecture diagram

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

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

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

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

Advanced graphical tools

� Rule� Point� Arc� Polyline� Polygon� Closed polygon� Internal polygon� On the fly switching between polygon,

polyline and arc� Perpendicular

Advanced graphical tools

� Parallel� Movement� Rotation� Vertex edit� Amalgamation� Subdivision� Copying� Length and angle

� Total station

� Linear intersection

Property object form (general)

Property object form (technical parameters)

Property object form (owners)

Property object form (history)

Amalgamation form

Division form

Land parcel binding

Free printing

Lessons learnt

� It is important to involve end users from the beginning, to get a clear vision about their needs. Don’t 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 couldn’t be created from the first release
