Notice to SHAPEFILE: The Shapefile format requires both files (.shp and .shx) when you are uploading. The .prj and .cpg files are optional. The Shapefile driver trims attribute names to 11 symbols when you write data. The 11 symbols is max value for attribute name in SHP format. Optionally you can specify the following files: CPG, PRJ, QIX. The CPG file contains codepage for fields data. PRJ contains a custom spatial refernce system. The QIX file increases a speed with geomtries searching.
SHP is the file extension for one of the primary file types used for representation of ESRI Shapefile. It represents Geospatial information in the form of vector data to be used by Geographic Information Systems (GIS) applications. The format has been developed as open specifications in order to facilitate interoperability between ESRI and other software products.
An SVG file is a Scalar Vector Graphics file that uses XML based text format for describing the appearance of an image. The word Scalable refers to the fact that the SVG can be scaled to different sizes without losing any quality.
