Question

Which of the following proprietary raster formats does ESRI use in its software products such as ArcInfo and ArcView GIS?

• A. GRID
• B. PNG
• C. GIF
• D. GeoTIFF

Hint:

ESRI’s native raster format = GRID (used for DEMs, surfaces).

Answer 1

The Correct Option is A

The question presented relates to the proprietary raster formats used by ESRI in its software such as ArcInfo and ArcView GIS. Let's examine the options provided:

• GRID: This is a proprietary raster format developed by ESRI. It is specifically used in ArcInfo and ArcView GIS software for storing raster data and is well-suited for advanced spatial analysis. Considering its integration with ESRI products, it can handle complex spatial structure and large datasets efficiently.
• PNG: Portable Network Graphics is a popular raster format for image files that provides lossless compression. While widely used for web graphics and some GIS applications, it is not proprietary to ESRI.
• GIF: Graphics Interchange Format is another common raster format known for its support of simple images with animations. Like PNG, it is not proprietary to ESRI and is not typically used for advanced GIS applications.
• GeoTIFF: This is an extension of the TIFF format with georeferencing information embedded. It is extensively used in GIS for raster data but remains an open standard rather than proprietary to ESRI.

Based on the analysis above, the proprietary raster format used by ESRI in its software products such as ArcInfo and ArcView GIS is GRID.
