I’ve been waiting for LandSerf 2.3 to officially come out of beta before posting on it, and that finally happened about a month ago. Publishing visualizations on the web. A free academic license is available to students, instructors, and non-profit academic researchers. Connect to almost any database, drag and drop to create visualizations, and share with a click. Tableau - Tableau is a powerful data visualization tool that can help anyone see and understand their data.Lightning Fast Graphic and resource-hungry Windows applications. Terrain visualization and analysis functions (its primary focus)You may also migrate your Windows PC or Linux, like Ubuntu (Intel-based Mac computers only). Users can quickly generate visualizations, animate them through time. For Universal Windows Platform development using Visual Studio 2015.VisIt is an Open Source, interactive, scalable, visualization, animation and analysis tool.From Unix, Windows or Mac workstations, users can interactively visualize and analyze data ranging in scale from small (<10 1 core) desktop-sized projects to large (>10 5 core) leadership-class computing facility simulation campaigns.Datum is always WGS84 after re-projection.In this example, reprojecting the UTM DEM to latitude/longitude will create a new DEM dataset for the new coordinate system:But I’ve found some problems with LandSerf’s coordinate re-projection function, at least for my test data, which limit its use as a general-purpose re-projection and/or format conversion utility. Once you’ve set the original data’s coordinate system, there’s a function to re-project it to one of 8 different coordinate systems using the Transform => Reproject these include UTM, Swiss National Grid, OS National Grid, French NTF National Grid, and several Albers equal area projections for North America. Unlike other GIS programs, there’s no button to put you into pan mode with the left mouse button, but right-clicking or mouse-wheel-clicking on the map display combined with dragging will let you pan when you’re in zoom mode.LandSerf will use a raster file’s georeferencing data, but won’t automatically assign a coordinate system to it you have to do this manually by double-clicking on the thumbnail to open the edit window:Then clicking on the Edit button in the Map projection section, and specifying the coordinate system used by the original data file:This is also the window used to modify raster or vector coloring schemes.As I discovered, you have to make sure to enter all of the requested information, including Zone letter for UTM otherwise, the coordinate system may be off, especially after re-projection.It’s pretty much required that all the datasets you use in LandSerf for analysis and combination be in the same coordinate system. Other quirks include an odd zoom function that uses mouse/mouse wheel movements to zoom in and out sometimes, the mouse wheel will only zoom out. Memorize that Ctrl-R command, since you’ll be using it a lot the intuitive approach to selecting and displaying a dataset, double-clicking on it, brings up a window to edit the data display properties. You select the primary data to display by clicking once on the corresponding thumbnail to turn it gray, then clicking Control-R to refresh the display and display that dataset you can also select a secondary set of data for some operations by right-clicking on the thumbnail to turn it pink.When saving an image, a worldfile will be generated with the correct extension for the saved file’s format (e.g.jgw for JPG files).To close a dataset, left-click on it to select it, and then choose File => Close raster (or vector) from the menu. Tif is listed as a valid extension when saving an image, the program will not save images in that format. And even though the program can open TIF files, and. So to avoid problems, have all datasets loaded into LandSerf be in the same coordinate system.Also, when saving images, the default format is GIF to save an image in a different format like JPG or PNG, you’ll have to manually specify the file extension.
Data Vizulization Tools For Windows, , Linus Free Academic LicenseA map rectification function for georeferencing, notable because it includes quadratic and cubic rectification many free GIS programs include only linear rectification.Re-reading this post, I see that it jumps around like crazy. A built-in scripting language for automating raster processing, and to do raster map algebra Feature extraction (pits, channels, passes, ridges, peaks, planar regions)Some of these can be done faster by the Windows program MicroDEM, but LandSerf can sometimes offer more flexibility in selecting the display colors used to represent the parameters other functions are unique to LandSerf.Also in common with MicroDEM, LandSerf also has functions to blend raster images, for instance a topo map blended with shaded relief:But for blending and 3D visualization, LandSerf falls far below MicroDEM in terms of speed, ease of use, flexibility, and quality of results. Curvature (profile, plan, cross-sectional, minimal, longitudinal, maximum, mean) There is a toolbar at the top, but even that is somewhat limited in the options it offers.With DEM data loaded, you can perform a number of DEM analyses or visualizations: Delete mac ads cleaner from macbook proI’m glad it’s available for the unique things it does, especially since it’s free, but it does have its share of quirks.Coming up: A look at LandSerf’s vector data functions.
