July 27, 2006: Placeways, LLC has announced the release of LayerLogic, an ArcGIS extension for real-time analysis using field formulas. The graphical, drag-and-drop interface lets users create “Smart Fields” in layer attribute tables. Smart Field values are formula-driven and self-updating.
Almost 100 analysis functions are available for automatically creating everything from on-the-spot calculations like “name of closest city” to sophisticated geospatial models. LayerLogic can also be used to create dynamic, formula-driven inputs to geoprocessing tools such as those found in the ArcToolbox or created with Model Builder.
