Philippine Government Website (gov.ph) , PGMA unveils the enhancement of flood forecasting and warning information system with more precise data on the extent and depth of inundation using its water runoff analysis software complimented by the Geographic Information System (GIS).
What is GIS?
A geographic information system (GIS) integrates hardware, software, and data for capturing, managing, analyzing, and displaying all forms of geographically referenced information.
GIS allows us to view, understand, question, interpret, and visualize data in many ways that reveal relationships, patterns, and trends in the form of maps, globes, reports, and charts.
GIS can integrate and relate any data with a spatial component, regardless of the source of the data. For example, you can combine the location of mobile workers, located in real-time by GPS devices, in relation to customers’ homes, located by address and derived from your customer database. GIS maps this data, giving dispatchers a visual tool to plan the best routes for mobile staff or send the closest worker to a customer. This saves tremendous time and money.
GIS Manages Geographic Information Sets
GIS manages, analyzes, and displays geographic knowledge, which is represented using a series of information sets. These information sets can include:
Maps and Globes
Interactive views of geographic data with which to answer many questions, to present results, and to use as a dashboard for real work. Maps and globes provide advanced GIS applications for interacting with geographic data.
File bases and databases of geographic information—features, networks, topologies, terrains, surveys, and attributes.
Processing and Workflow Models
Collections of geoprocessing procedures for automating and repeating numerous tasks that perform analysis.
GIS datasets are more than RDBMS tables. They incorporate advanced behavior and integrity like other information systems. Data models—the schema, behavior, and integrity rules of geographic datasets—play a critical role in GIS.
Documents describing the specifications and properties of the data. A document catalog enables users to organize, discover, and gain access to shared geographic knowledge.
