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. 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. Note that the same approach can now be used within the standard FME XML reader by using the reader parameter confguration type = 'Feature Paths' and flatten options set to enable flattening. Note** This example requires FME 2012+ So, given the following input, xml_string = <Feature><attribute1>John</attribute1><attribute2>Vancouver</attribute2><activeDate><from>11-22-99</from><to>12-11-09</to></activeDate></Feature> to: <? Remember you can always have as many queries as you want. 1. e=1 e=2

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. 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. "Open-access software is designed from the project’s inception in a way that reduces the barriers that typically discourage end-users from examining the algorithm and implementation details associated with software artifacts."

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 strategy for generalizing bends in a line looks as follows: * The parameter "diameter" is used to calculate the area of a reference circle. * For each line, determine the locations of the bends. * For each bend, calculate its actual area. * For each bend, calculate its circumference. Example 1: Topological CheckingBack to Top by Dmitri Bagh Often it is better to see a simple demo, than to read a long detailed explanation. Existing generalization algorithms in FME consider neither mutual locations of the features nor possible dangerous changes to each indvidual feature. Old Style Before Generalization It can control: Sherbend Style

SimpleDEMViewer About SimpleDEMViewer browses DEM ( Digital Elevation Model ) data as a relief map. It displays colored map with shading. Since no data is included in this package, user should prepare DEM data separately. DEMs supported GTOPO30, HYDRO1K, SRTM, SRTM DTED, SRTM30plus, ETOPO1, ETOPO2, ETOPO5, GLOBE, GDEM, GeoTiff, netCDF, some BIL forms, USGS Ascii, USGS SDTS, ArcInfo Ascii, DEMs from GSI of Japan. Functions Displays color elevation map in a window with or without 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! Descriptions First a description. To do the merge requires some common information; usually a common ID number. FeatureMerger The FeatureMerger is for when both sets of data are being read in a workspace. Joiner The Joiner has only a single input port. FeatureReader + SpatialFilter The FeatureReader does a similar job to the Joiner, but allows matching of features by spatial relationship rather than a common attribute value. SQLExecutor The SQLExecutor carries out a SQL command on a database – that command could be a select statement with a where clause, effectively allowing joins to be carried out. The results were as follows: Caution!

Route Generator The FME Evangelist » FME 2011 Special: The FeatureReader Hi all, If you’ve used FME2011 – or attended any of our FME World Tour events – then you may have noticed a new transformer called the FeatureReader. It’s not often a single transformer gets a whole FME Evangelist post to itself, but this remarkable piece of functionality is going to be very popular with power users, besides simple enough for anyone to understand. Ladies and gentlemen, I give you the FeatureReader! What Does it Do? Well, we like to give our FME transformers names that are self-explanatory, and it doesn’t get much simpler than this. When the parameters dialog is opened, the standard FME Reader parameters are there to be entered: When the workspace is run, each feature that enters the transformer triggers reading from this dataset. A Creator transformer can be used to trigger the FeatureReader to read that data, like this: OK, so there’s a little more to it than that; otherwise we could just rely on Readers in the workspace. Regards, Join Us at an FME Event in Spring 2014

G.Projector G.Projector transforms an equirectangular map image into any of over 125 global and regional map projections. Longitude-latitude gridlines and continental outlines may be drawn on the map, and the resulting image may be saved to disk in GIF, JPEG, PDF, PNG, PS or TIFF form. G.Projector is a cross-platform application that runs on Macintosh, Windows, Linux and other desktop computers. The current version of G.Projector is 1.8, released 2015-09-18. Get G.Projector G.Projector requires that your computer have a Java 7 or 8 runtime environment, or better, installed. Download G.Projector Additional CNO/CNOB overlay files compatible with G.Projector are available from the Panoply software collection of optional "outline overlays". Documentation and Credits Contact If you wish to be notified when new versions of G.Projector are released, if you would like to report a bug, or if you would like to become a G.Projector beta tester, please contact the author, Dr.
