GIS on Weekend: SIG EPI dan SaTScan
The 4th meeting at the “GIS on Weekend” on last Saturday (23/08/08) was presenting topic of SlG Epi and SaTScan utilization for epidemiology. Those applications can perform health spatial data analysis.
SIG Epi is current GIS application developed by Health Analysis Information and System-Pan American Heatlh Organization (HAIS–PAHO) for spatial analysis in epidemiology. PAHO has cooperated with ESRI to develop SIG Epi so that only shapefile (SHP) format can be run by this application. The output is useful for people who concern on epidemiology and public health, also for managerial decision maker. It has several features, such as descriptive statistic, correlation, health service, etc. The strength point of this apllication is package of data analysis including in the application (on menu of epi analysis) so that it does not need additional application to do analysis.
The SIG Epi can be downloaded at http://ais.paho.org:80/sigepi/dwld/SIGEpi_En.zip, It is free trial for the 90 days and we can buy the licensed one for the full version. It can be run by using Microsoft Windows 95/98/Me/NT/2000/Xp. It needs processor of 486, pentium, or higher and memory of 128 MB with 40MB free spaces.
SaTScan is a free software that analyzes spatial, temporal and space-time data using the spatial, temporal, or space-time scan statistics. It is designed for any of the following interrelated purposes:
- Perform geographical surveillance of disease, to detect spatial or space-time disease clusters, and to see if they are statistically significant.
- Test whether a disease is randomly distributed over space, over time or over space and time.
- Evaluate the statistical significance of disease cluster alarms.
- Perform repeated time-periodic disease surveillance for early detection of disease outbreaks.
To perform the SaTScan output in map, we need application of Epi Info or ArcView-GIS. So you can install those two applications together with the SaTScan to produce the spatial analysis map.
At last, this GIS on weekend training has been ended for this August. Hopefully, we will arrange the similar training after the Ramadhan. For anyone who is interested in being the GIS expert, don’t worry! You still have a chance to make it real.
GIS on Weekend: Thematic Mapping
Today, people interest to GIS becomes greater since it can be applied to various sectors. It is also shown by the enthusiasm of participants in “GIS on Weekend” training held by the SIMKES, they come from various backgrounds, e.g. lecturers, graduate students, and staff of health office. In the third meeting on last Saturday (August 16, 2008), the topic was “thematic Mapping”, that was, participants were taught the way to make a thematic map. A thematic map displays spatial pattern of a theme or series of attributes and emphasizes spatial variation of one or a small number of geographic distributions. A thematic map can be made by converting Shapefiles (SHP) into a kml files which can be applied to Google Earth.
SHP is a vector format (format proprietary open specification) as the product of ESRI, a GIS software company (ArcInfo, ArcView, ArcIMS, dan ArcGIS). This format has 3 extension file, they are:
- Main file: *.shp
- Index file: *.shx
- DBase file: *.dbf
Data conversion from SHP files into kml files can be done in several ways. There are software which provide this conversion application, such as Arc GIS 9.2, Arc view GIS 3x (extension), DNR Garmin 5.3, Mapwindow 45CF with plug-ins Shape2earth 1.45.01, Shp2kml, etc. Among those softwares, Shp2kml is the easiest one and can be run indepedently without the main program. This application can be downloaded in http://www.zonums.com:80/files/Shp2kml.zip. After downloading the application, unzip the shp2kml.zip become shp2kml.exe.

GIS on Weekend: Part 1
GIS on weekend is a set of training of Geographic Information System Implementation (GIS) for Health with 4 sessions. The first session has been held on Saturday, August 2, 2008. The topic was “GIS Implementation for Health” with the speakers of Anis Fuad, DEA (Overview of Health GIS), Sugeng Harianto (GIS Tools: Epimap, EpiInfo), and Adi Widagdo (Introduction to GPS). At last, a case study was lead by Anis Fuad to learn about GIS throughout the existed cases.
GIS was an information system with current data for showing the location in map. Along with the recent technology development, GIS also has been developed on the basis of computer and can be applied on other sectors including the health sector.
GIS can be used to answers the following questions:
- What did happen in a place?
- Where was something?
- What changes have happen during ….to…?
- How was the distribution pattern of something?
- How if…?
In public health sector, GIS based-spatial analysis is used for:
- Disease controlling (vector mapping, disease cases, distance identification, case clustering/cause of sickness)
- Health program planning
- Health program monitoring and evaluation
- A suporrting tool for health personnel allocation
The GIS integrate various data, e.g. satellite data, aerial photograph, digital maps, tabular information, etc., then forming new information in thematic map.
Before making a thematic map, we should prepare the spatial data to show location of an area. Gathering spatial data, we can use a GPS (global positioning system), that is a satellite based-navigation system which informing definite position of a location in the earth. The GPS receiver can detect the 24 orbited-satellite signals upon the earth. By using distance measuring function, we can determine position of a location in the world.
After gathering spatial data from the GPS, so these data are processed by using GIS software such as Epimap, Quantum GIS, ArcView, etc. At last, it can produce a complete map with points of observed location.
GIS has several advantages for health sectors, particularly for spatial analysis which can support decision making corresponding to public health.
For the next session, the topic is Spatial Data for Mapping. The registration for the next training sessions is still opened. Just contact the SIMKES secretariat on (62)274 -549432.
