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. 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 = to: <? 1. d_e=1 d_f=a d_e=2 d_f=b
Welcome to OSGeo-Live 7.9 — OSGeo-Live 7.9 Documentation Kosmo-Plataforma SIG libre corporativa - Home QGIS Labs QGIS Tutorial Labs Home This is a set of tutorial labs for Quantum GIS, an open source geographic information system. The labs are based on QGIS version 1.7.3 (last updated 5/1/2012). I would appreciate hearing comments and suggestions. The labs make use of the following data sets: Field 5 (this is a wheat field located in Central California) Brown's Pond (this is a data set first used in Geographic Information Systems and Cartographic Modeling by C.
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: * 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 Old Style Before Generalization It can control: 1) Self-intersections;
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. 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. For format, the spatial data was written to Shape, but the non-spatial to both CSV and SQLServer.
