The research findings showed that the image of Landsat 7 Bands 432 in 1:11.000 – 1:15.000 scale could be used to interpret land use and land cover. The researcher also analyzed the soil texture, permeability and land plasticity index, bedding, weathering level, the density of joints, the depth of weathering, the existence of springs, slopes, and slope cutting.

ArcGis 9.3 and ArcView 3.2 software was used for map analysis. The research design that was used in the study was image interpretation of Landsat 7 Band 432 Satellite and primary data of the landslide causes (the data of soil and rocks, map interpretation, and variable scoring of landslide. This research was carried out in Batu, East Java. The system dedicates a great deal of effort to the initial study of geospatial analysis and visualization for novice users including those with no past experience using Geographic Information Systems.Ībstract This research is aimed to map potential landslide areas, identify types of landslide, and draw a map of potential landslide level. We implemented a prototype by using web service standards recommended by the Open Geospatial Consortium (OGC) such as Web Map Service (WMS), Web Feature Service (WFS) and Styled Layer Descriptor (SLD) to provide a principle for communication and allow users to visualize spatial information as thematic maps. Novice users who have no GIS software experience or have no digital base map can simply input a plain text file with location identifier field such as place name or gazetteer to generate thematic maps online. In this study, we developed thematic mapping services that can be applied to non-spatial data format served through powerful map services solutions. The users with limited GIS knowledge or people who do not own digital map data are normally having difficulties to create output thematic maps from generic data. However, visualizing thematic maps through the Internet is still limited to fix contents and restrict changes of the input data. Spatial analysis packages and thematic mapping are available in a number of traditional desktop GIS. Users may also observe the changes of land cover manually. Users can use the system using a web browser and run various functions such as layer selection, ZoomIn, ZoomOut, and GetFeatureInfo. The user interface was built using the GeoExplorer as web-based software to compile and publish map mapping application. The elements of application server were GeoServer as a web map server and Apache web server. In the research, the used data was of shapefile format and stored in PostgreSQL/PostGIS DBMS.

The software consists of three main components: database management system (DBMS), application server, and user interface. To handle this problem, this research built a WebGIS application for land cover monitoring in Central Kalimantan Province using OpenGeo Suite 3.0.

This interoperability issue appears in many cases of land cover information dissemination in Indonesia. Requirements of data from different party with various formats and locations are increasing. It can facilitate BPBD of Riau province to collaborate with the dissemination of disaster information BPBD of districts and cities in Riau Province. The benefit is to obtain spatial data infrastructure that supports Web Map Service standard, than the disaster map can be displayed in any client that supports standard of Web Map Service. The result of this system is Geographic Information System disaster using a standard Web Map Service. In addition, using a standard protocol of the Open Geospatial Consortium is that Web Map Service. The purpose of this study is to propose GIS using the application QuantumGIS (QGIS) to digitize the map and manage the data storage. In one side, when the exchange of data among BPBD of districts and cities in Riau Province is by telephone. In addition, users must use a temporary storage (flash or hard drive) to move data and then import into the GIS user. The obstacle of this system is that the user must be directly related to the GIS when they want to know disaster information. BPBD of Riau Province uses ArcGIS to display spatial information of disaster. Regional Disaster Management Agency (BPBD) is oriented organization of disaster management.
