![]() ![]() In this type of continuous surface, there has to be a source. Surface characteristics of this type of movement include salt concentration moving through either the ground or water, contamination level moving away from a hazardous spill or a nuclear reactor, and heat from a forest fire. The first type of movement is through diffusion or any other locomotion in which the phenomenon moves from areas with high concentration to those with less concentration until the concentration level evens out. These surfaces are characterized by the type or manner in which the phenomenon moves. ![]() Illustrations of progressively varying continuous data are fluid and air movement. These include elevation (the fixed point being sea level) and aspect (the fixed point being direction: north, east, south, and west).Īnother type of continuous surface includes phenomena that progressively vary as they move across a surface from a source. One type of continuous surface is derived from those characteristics that define a surface, in which each location is measured from a fixed registration point. Continuous data is also referred to as field, nondiscrete, or surface data. Discrete objects are usually nouns.Ī continuous surface represents phenomena in which each location on the surface is a measure of the concentration level or its relationship from a fixed point in space or from an emitting source. Other examples of discrete objects include buildings, roads, and parcels. Where the water’s edge meets the land can be definitively established. A lake is a discrete object within the surrounding landscape. A discrete object has known and definable boundaries: it is easy to define precisely where the object begins and where it ends. To save the resulting grid as a raster, right-click on the raster that was created then click Data > Export Data.Discrete data, which is sometimes called thematic, categorical, or discontinuous data, most often represents objects in both the feature (vector) and raster data storage systems.Select the variable you wish to view, and ensure the X dimension and Y dimension are appropriate (longitude & latitude, x coordinate and y coordinate, etc.).Once it's selected, wait for the variables/attributes to load and fill in the remaining properties.In the Toolbox window, scroll down and click to open Multidimension Tools.In the Geoprocessing menu, click ArcToolbox.Global Mapper only supports some NetCDF files, namely ESA CCI Soil Moisture files.Global Mapper: File > Open Data File(s).It is also a community standard for sharing scientific data." ( Source) The following datasets use the NetCDF format: NetCDF (.nc), or Network Common Data Form, "is a set of software libraries and machine-independent data formats that support the creation, access, and sharing of array-oriented scientific data. This information is accurate for ArcMap Desktop 10.8, ArcGIS Pro 3.0, Global Mapper 22, and QGIS 3.16. Is the file format you have not listed here? Contact us and/or consult lists of all raster and DEM file formats supported by ArcGIS Desktop, ArcGIS Pro, Global Mapper, and QGIS. DTMs: digital terrain models are either synonymous with DEMs or comprised of a network of vector points instead of a continuous raster. ![]()
