TatukGIS Free Viewer The TatukGIS Editor is a professional, general-purpose desktop GIS mapping and data editing application with built-in scripting environment for customization and feature extensions. Features include: Viewing Natively (without import or format conversion) opens and displays a wide range of vector, image, grid, and SQL database layer formats, including advanced spatial server geodatabases. WMS, WFS, and WMTS mapping services may be opened from the web. Comprehensive visual layer property, legend, and scale controls provide for deep customization of the map appearance. FMEpedia - Reading Complex XML or GML using the XMLFlattener Many users have problems reading complex XML or GML. In the past you had to make xfMap or XQuery scripts. To address this we recently we added the concept of XML flattening to our XML and GML readers. However, sometimes you have XML elements or attributes that need to be processed within a workspace, such as the result from a URL request. For this you can use the new XMLFlattener transformer. With XMLFlattener, all you have to do is feed it XML on an attribute or from a file, specify the node you want to query, and XMLFlattener transformer will make an FME feature for each occurrence of that node in your XML and flatten all the elements nested within that node into simple FME attributes.
Map a GPS data file with Google Earth This form will import your GPS data file (e.g., GPX), or plain-text data (tab-delimited or CSV), and create a KML file that you can view in the Google Earth application or import into Google's "My Maps"/"My Places" system. (You might also be interested in the Google Maps input form, which can create an interactive map that can be viewed in almost any Web browser; you can even use KML/KMZ files as input. For SVG or JPEG maps, use the "classic" map form. To resize and/or colorize Google Earth markers based on a particular field, use the data form.)
Mesh Generation and Grid Generation: Software This is a list of public domain and commercial mesh generators (click here for other sources of interest). I have listened only programs for which online information exists. There is also a section on papers that review mesh generators. If you are interested in special programs, the following links might guide you directly to interesting places: Early 2015 Geospatial MOOC Roundup Note: These courses are listed in chronological order, based on their next availability. 1) Introduction to Geospatial Technology Using QGIS This course provides a rich introduction to the booming technology field of Geographic Information Systems, known as GIS. The GIS industry is exploding at double-digit employment and income numbers and promises employment opportunities well into the future. Students will learn the fundamentals of GIS and how to build digital maps using open source software that allows free unlimited use for private or commercial applications.
Whitebox GAT The Whitebox GAT project began in 2009 and was conceived as a replacement for the Terrain Analysis System (TAS). Whitebox GAT was intended to have a broader focus than its predecessor, positioning it as an open-source desktop GIS and remote sensing software package for general applications of geospatial analysis and data visualization. Whitebox GAT is intended to provide a platform for advanced geospatial data analysis with applications in both environmental research and the geomatics industry more broadly. It was envisioned from the outset as providing an ideal platform for experimenting with novel geospatial analysis methods. Equally important is the project’s goal of providing a tool that can be used for geomatics-based education. An important characteristic of Whitebox GAT is the unique open-access development philosophy adopted by the project, which lends itself to experimenting with geospatial algorithm development.
FMEpedia - SherbendGeneralizer Examples SherbendGeneralizer is an FME 2011 transformer for 'smarter' generalization, which preserves original topology of the features. The goal of the Sherbend algorithm is to reduce unnecessary details on a line based on the analysis of the line’s bends. Sherbend is a constraint based algorithm that preserves topology of the lines and points in the input dataset. The Sherbend algorithm iteratively generalizes bends in a line by using the diameter parameter to select bends for generalization. The generalization process may eliminate, reduce, or combine bends, while resolving conflicts. The strategy for generalizing bends in a line looks as follows: GeoHack - Toolserver wiki GeoHack is a modified version of map sources from Egil Kvaleberg's gis extension. It is designed to do simple HTML replacements of a template on Wikipedia and serve it to the client. It is used by Wikipedia to provide links to various mapping services, when a user clicks on a link with geographical coordinates.
SurGe - gridding and mapping software Introduction SurGe is a computer program which enables to generate a surface as an interpolation (approximation) function of two independent variables. The program has the following basic features: Implements the interpolation / approximation method ABOS. Basic input is a simple ASCII file containing X, Y and Z coordinates of points irregularly spaced in some region.
Overview Inkscape is an open-source vector graphics editor similar to Adobe Illustrator, Corel Draw, Freehand, or Xara X. What sets Inkscape apart is its use of Scalable Vector Graphics (SVG), an open XML-based W3C standard, as the native format. For Designers of all Kinds The design process may begin by doodles on a napkin, a sketched mindmap, a photo of a memorable object, or a mockup in software which really wouldn't work to complete the project. SimpleDEMViewer About SimpleDEMViewer browses DEM ( Digital Elevation Model ) data as a relief map. It displays colored map with shading. The FME Evangelist » FME2011 Use Case: Joiner vs FeatureMerger Hi FME’ers, Interacting with FME users I see various points of view on the merits of the Joiner transformer versus the FeatureMerger. Although both transformers carry out similar actions, it’s not clear to users when you should use each of these – particularly in relation to workspace performance. So this post will indulge in some investigative journalism! I’ll compare and contrast these transformers, to see where you would want to use each of them, and throw other transformers – such as the updated SQLExecutor and the new FeatureReader - into the mix as potential alternatives. Descriptions First a description. In general these transformers are used to merge features together.
3D converters software - on Linux - Notes and Code Introduction : This is a page of links to 3D software files --- files that can be used to install (or develop) 3D CONVERTER programs --- on Linux systems --- especially on Ubuntu (around version 9.10 = 2009 Oct, Karmic Koala - and beyond). Many of the links are to locally stored files (source and/or binaries/packages). The code is stored locally both for convenience (especially mine), AND because some of the 3D-converter authors are going on to other projects (or to other worlds) and it is questionable whether the code will be preserved for future generations to build upon. Furthermore, the info on 3D converters for Linux is consolidated (to a great extent) on this one page --- instead of in many bookmarks in my web browsers on my various machines.
QGIS Plugins planet Recently, in order to nicely plan ahead for a birthday lunch at the agritur Malga Brigolina (a farm-restaurant near Sopramonte di Trento, Italy, at 1,000m a.s.l. in the Southern Alps), friends of mine asked me the day before: “Will the place be sunny at lunch time for a nice walk?“ [well, the weather was close to clear sky conditions but mountains are high here and casting long shadows in the winter time]. A rather easy task I thought, so I got my tools ready since that was an occasion to verify the predictions with some photos! Thanks to the new EU-DEM at 25m I was able to perform the computations right away in a metric system rather than dealing with degree in LatLong.
