KO KASAN MENENE MA'ANAR KALMOMIN GEOGRAPHIC INFORMATION SYSTEM?
Meaning of GIS in a Simplified ways:
-Geographic Information System (GIS) is a computer system build to capture, store, manipulate, analyze, manage and display all kinds of spatial or geographical data.
-GIS application are tools that allow end users to perform spatial query, analysis, edit spatial data and create hard copy maps.
-GIS can also be defined as an image that is referenced to the earth or has x and y coordinate and it’s attribute values are stored in the table. These x and y coordinates are based on different projection system and there are various types of projection system.
Most of the time GIS is used to create maps and to print. To perform the basic task in GIS, layers are combined, edited and designed.
-In the strictest sense, GIS is a computer system capable of assembling, storing, manipulating, and displaying geographically referenced information (that is data identified according to their locations). (USGS)
GIS can be used to solve the location based question such as “What is located here” or Where to find particular features? GIS User can retrieve the value from the map, such as how much is the forest area on the land use map. This is done using the query builder tool. Next important features of the GIS is the capability to combine different layers to show new information. For example, you can combine elevation data, river data, land use data and many more to show information about the landscape of the area. From map you can tell where is high lands or where is the best place to build house, which has the river view . GIS helps to find new information.
GIS Works in the following formats:
-Visualizing Data: The geographic data that is stored in the databases are displayed in the GIS software.
-Combining Data: Layers are combined to form a maps of desire.
-The Query: To search the value in the layer or making a geographic queries.
Thank you for your time. And see you in the next write up.
