Improving Performance for Distance-Based Operations - Latest

A PGD index file is a supplemental file to the TAB file set that can make performance for native, native extended (NativeX), and seamless TABs comparable to that of GSB files. The PGD Builder, a command-line utility, is available to generate these specialized index files to improve performance of certain distance-based operations for native datasets containing lines and polygons. An index built using the PGD Builder is helpful when the data you are searching is based on lines and regions and you are using:

• the Point in Polygon stage, when you are including distance
• the Find Nearest stage, when the input is a point (whether or not you are including distance)
• SearchNearest operations in the Feature Service, with an input point and a line or polygon search table

The PGD Builder utility can be downloaded from the Spectrum Spatial section of the Welcome Page, under PGD Builder on the Utilities tab. A link to the is also available on the Welcome Page next to the download link for the utility.
