GIS & REMOTE SENSING
GIS integrates many different kinds of data layers using spatial location. Most data has a geographic component. GIS data includes imagery, features, and basemaps linked to spreadsheets and tables.
SRTM – Shuttle Radar Topography Mission On 23 September 2014, the White House announced that the highest-resolution topographic data generated from NASA‘s that is Shuttle Radar Topography Mission (SRTM), it was released globally by late 2015. The Shuttle Radar Topography Mission is elevation data on a near-global scale, acquired from the Space Shuttle, to generate […]
Digital Elevation Model (DEM) Download Digital Elevation Model (DEM) widely known as a Digital Terrain Model (DTM). A DEM can be used to create topographic maps of overland terrain, as well as bathymetric maps. A DEM data can be represented as a raster dataset, or as a vector-based Triangular Irregular Network (TIN). Best 6 Free
GeoTIFF What is a GeoTIFF? The GeoTIFF stands for Geographic Tagged Image File Format. It was initially developed during the 1990s. Geographic TIFF is a format extension for storing Georeference and Geocoding information in a TIFF format. It can store a broad range of geo-referencing information, as well as projected coordinate systems. Supported projections include
Vector Data & Raster Data Vector Data A Vector data feature its represent shape using Geometry. The geometry is made up of one or more interconnected vertices. A vertex describes a position in space using an X, Y and optionally Z axis. Geometries which have vertices with a Z axis are often referred to as
