30m resolution global elevation data derived from Advanced Spaceborne Thermal Emission and Reflection Radiometer satellite images. [6] OpenTopography: OpenTopography facilitates community access to high-resolution, Earth science-oriented, topography data, and related tools and resources..
A GIS analysis package for basic and advanced spatial analysis, an Image Processing system with extensive hard and soft classifiers including machine learning classifiers, integrated modelling environments including the Earth Trends Modeller for image time series of environmental trends and Land Change Modeller for land change analysis and ...
Vector file sizes are usually smaller than raster data, which can be tens, hundreds or more times larger than vector data (depending on resolution). Vector data is simpler to update and maintain, whereas a raster image will have to be completely reproduced. (Example: a new road is added).
The PDF format is widely accepted and is considered the de facto standard for printable documents on the web. This means that users do not require the any proprietary plug-in to read geospatial PDFs created following the PDF 1.7 specification, which was published as ISO 32000-1 standard . [ 3 ]
A supervised classification is a system of classification in which the user builds a series of randomly generated training datasets or spectral signatures representing different land-use and land-cover (LULC) classes and applies these datasets in machine learning models to predict and spatially classify LULC patterns and evaluate classification accuracies.
Systems Tool Kit (formerly Satellite Tool Kit), often referred to by its initials STK, is a multi-physics software application from Analytical Graphics, Inc. (an Ansys company) that enables engineers and scientists to perform complex analyses of ground, sea, air, and space platforms, and to share results in one integrated environment. [1]
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.
The system was later extended to support data from the Earth Resources Technology Satellite and the Mariner planetary probes. [4] A command line interpreter allowed the user to call up data with short commands, YK T 500 1200 USA would generate a display of the 500 mb temperature data from the 1200 UTC measurements over the USA.
