Vectors models are points, lines and polygons Vector data is not made up of a grid of pixels. Instead, vector graphics are comprised of vertices and paths. The three basic symbol types for vector data are points, lines, and polygons (areas).

A vector based GIS is defined by the vectorial representation of its geographic data. Visit the Esri vector basemap group to see sample vector styles you can use as well as what can be done to change the look of the map. Sample styles include simple color changes and more involved redesigns using sprite and font changes. The vector basemaps are updated frequently and include regular contributions from the GIS community.

Vector 3D maps allow you to work with such objects like streets, rivers, routes and others, where you may add and update properties of the objects with additional information with adding new layers. Vector data are stored as ESRI shapefiles Grid (raster) data are stored as DIVA gridfiles Each "shapefile" consist of at least three actual files. This is a commonly used format that can be directly used in Arc-anything, DIVA-GIS, and many other programs. It can be imported to most other GIS programs.

Ett geografiskt informationssystem (GIS) är ett datorbaserat system för att samla in, lagra, analysera och presentera geografiska data .

A table is like a spreadsheet. Each column in the table is called a field.

Where vector data (coordinates that create an image) is somewhat abstract, raster data is quite literal. Raster data is grid or pixel based. Commonly found as aerial surveys, topographic maps, and satellite imagery, raster file extensions include TIFF, PNG, and JPEG.. In GIS mapping, raster data generally represents surfaces..

This is an excellent platform, I enjoy every bit of information and manual guide,this is so precise now I can explore a lot about Raster-vector interrelationship… Thank you so much. I will recommend anyone who seek to understand how Raster-vector conversion works better with GIS to resort to this blog. A GIS file format is a standard of encoding geographical information into a computer file.They are created mainly by government mapping agencies (such as the USGS or National Geospatial-Intelligence Agency) or by GIS software developers. Pada umumnya, data GIS disajikan dalam bentuk vektor. Dalam model data vektor, garis-garis atau kurva merupakan sekumpulan titik-titik yang dihubungkan. Sedangkan, luasan atau poligon juga disimpan sebagai sekumpulan titik-titik, dengan catatan bahwa titik awal dan titik akhir poligon memiliki nilai koordinat yang sama (poligon tertutup sempurna).
