MrSID (pronounced Mister Sid) is an acronym that stands for multiresolution seamless image database.It is a file format (filename extension.sid) developed and patented [2] [3] by LizardTech (in October 2018 absorbed into Extensis) [4] for encoding of georeferenced raster graphics, such as orthophotos.
ArcGIS 9 was released in May 2004, which included ArcGIS Server and ArcGIS Engine for developers. [39] The ArcGIS 9 release includes a geoprocessing environment that allows execution of traditional GIS processing tools (such as clipping, overlay, and spatial analysis) interactively or from any scripting language that supports COM standards.

MapInfo Pro is a database which manages information as a system of Tables. Each table is either a map file (graph) or a database file (text) and is denoted the file extension .TAB. Objects (points, lines, polygons) can be enhanced to highlight specific variations on a theme through the creation of a Thematic map. The basic data is overlaid with ...
In a manner similar to that shown in figure 11, the stack-unit's occurrence (the map unit's outcrop), geometry (the map unit's boundaries), and descriptors (the physical properties of the geologic units included in the stack-unit) are managed as they are for a typical 2-D geologic map. [31] Raster-based stacked surfaces depict the surface of ...
It is a tool for visualizing and processing spatial data, characterized by its friendly user interface and access to multiple data formats, both vectorial (in a file, such as Shapefile, GML, KML, DWG and DXF, or a database, such as PostgreSQL, MySQL, or Oracle) and raster (TIFF, ECW, MrSID, or other georeferenced image files, such as BMP, GIF ...
Shapefiles : are a data exchange format created by ESRI and one of the most widely used GIS/geodata formats. One "shapefile" usually include four different files : .shp, .shx, .dbf, .prj. First three files must all be present in order to use the data. Each shapefile can hold only one geometry type.
