How do SDIs work

• Data and metadata is
• Good coordination is

Data and metadata is managed centrally

• But by data

Good coordination is necessary between participating i ti generator/owner

• Tools consume data

i i

• rganisations
• Definition of standards

is important via services on computer networks is important

How do we get all the data into GIS?

• Address Geocoding (conversion of address into

Address Geocoding (conversion of address into coordinates)

– Possible only in developed countries with well-defined address system

C ll t di t i GPS

• Collect coordinates using GPS
• The primary location is the household

Other scale of mapping could be

• Other scale of mapping could be

– Census tracts/blocks – Villages – Grid of user-defined size

HDSS site zoomed

• 1. Immunization database was linked
• 2. Problem of database updation

Vadu story,..now

• 22 villages have been mapped and GPS

coordinates of households is under progress

• GPS Location of all kinds of health facilities
• Detailed road network
• Used for identifying areas with low accessibility

Vadu SHDI,..now and the future

Development of spatial health data infrastructure (SHDI) using open source ( ) g p technologies Why Open Source? Why Open Source?

• Proprietary GIS softwares are expensive and

source cannot be modified and distributed

• There is a large collection of mature open

source GIS technologies available

Vadu SHDI,..now and the future

• MySQL, which is a popular open source relational

database management system with support for GIS data, is used to store GIS data in addition to HDSS data is used to store GIS data in addition to HDSS data.

• It acts like a data storehouse and gives remote access to

most current spatial and HDSS data. p

• The SHDI houses census maps at village level containing

approximately 200 demographic, amenities and land use t d t il d d h h ld l ti parameters, detailed road maps, household locations and associated HDSS data

• Environmental variables like industries and their types

Environmental variables like industries and their types, source of water, sanitary, medical, utility, waste disposal facilities that are not available in census are stored

Households Birth Inmigration Households (household_id) Death Outmigration Individuals Individuals (household_id) (individual_id) University of Pune Vadu, India Ghana

Vadu SHDI,..now and the future

• KosmoGIS, an open source GIS application developed

by Sistemas Abiertos de Informacion Geografica (SAIG), Spain is used to view and analyze GIS and HDSS data Spain is used to view and analyze GIS and HDSS data stored in MySQL database.

• We are now able to answer the question,

WHERE? WHERE?

in addition to how many!

– Eg. How many children were born in 2008 and WHERE?! – How many children died in 2008 and WHERE?! University of Pune Vadu, India Ghana

Vadu SHDI,..now and the future

• We can synthesize maps on demand
• It is also able to retrieve maps from remote

web mapping service (WMS) servers to include in current view include in current view

• The architecture of SHDI permits to visualize

GIS-HDSS data as soon as it is input into the database thus ensuring access to most database, thus ensuring access to most current data

• MySQL database as well as KosmoGIS

conform to OpenGIS standards thus allowing interoperability with other GIS and database applications in case need may arise.
