LandWorks Inc., a developer of innovative land management software, has again advanced its integration with Esri technology by creating a new Spatial Alignment Tool that runs as an ArcGIS Desktop extension and automates tedious polygon editing tasks for land mapping professionals and land asset managers. The new software can be used in any country and in any industry that maps land boundary polygons using Esri’s ArcGIS Platform.
Previously, when a more accurate version of land grid (Public Land Survey sections, Texas abstracts, etc.) or tax parcel data was made available by a data vendor, any polygons in an updated area of the grid had to be manually realigned to snap to the more accurate grid. With LandWorks’ Spatial Alignment Tool, manual realignment is no longer necessary.
“Land grid and parcel data providers typically deliver quarterly updates to customers. The labor intensive task of realigning mapped land polygons to the updated version has been a long-term challenge that many companies choose to forgo rather than implementing the more accurate version of the land grid or parcel data,” said Jerry Bramwell, President and CEO of LandWorks. “With our new Spatial Alignment Tool, what once required months to complete now takes hours, resulting in more accurate land agreement polygon boundaries without the high cost of manually snapping them to the updated grid or parcel data.”
The Spatial Alignment Tool works with any vector land grid or parcel data. Users need an original source land/parcel grid and an updated source land/parcel grid. The tool detects vertex movements between the original land/parcel grid and the corresponding updated layers, then automatically aligns the selected polygons based on those detected changes. Users can easily adjust the tolerance and alignment settings if not satisfied with the results. Once the alignment process is complete, users can review the aligned polygons before committing them to the enterprise geodatabase.
In addition to easily maintaining the accuracy of GIS data for better analysis, the new software also saves companies significant time and money if they choose to switch land grid or parcel data suppliers for quality, supply or budgetary reasons.
“Traditionally, companies have been hesitant to change land grid or parcel data vendors because of the seemingly Herculean task of transferring the polygons from one land grid or parcel layer to another,” said Bramwell. “Automating this task using the Spatial Alignment Tool now makes switching suppliers a viable option.”
