GeoJSON to GeoTIFF – Vector to Raster Conversion

GeoJSON is an open standard geospatial data interchange format that represents simple geographic features and their non-spatial attributes. It is based on JavaScript Object Notation (JSON) and serves as a format for encoding various geographic data structures.

TIFF, also known as the Tagged Image File Format, is a file format designed for transferring, storing, and displaying raster images. It is commonly used for scanned aerial photography, maps, digital satellite imagery, and other geographic data.

GeoTIFF is a metadata standard that is in the public domain. It enables the embedding of georeferencing information in a TIFF file. This additional information can include projections, coordinate systems, ellipsoids, datums, and all other necessary details to establish the precise spatial reference for the file.

WHAT IS KML (Keyhole Markup Language)? – KML (Keyhole Markup Language), is an XML grammar and file format for modeling and storing geographic features such as points, lines,images, and polygons for display in the Google Earth client.KML is based on GML, although it doesn’t formally import GML schemas. KML language is used by a variety of GIS and mapping applications and the specifications are freely available to the public and available to the user community without charge or restriction. The Google Earth client supports a number of display features for rich presentation of GIS data. All of the features supported by the Google Earth client are described in KML. The Google Earth client supports a number of two-dimensional geometric shapes for display in the 3D viewer.
