Utility networks are related to a land base by digitised overlay or off-set measurements. These relations may be of cartographic or survey accurate nature.

Should change to the land base occur, conventional ‘rubber sheeting’ methods are error-prone and labour intensive while conventional GIS techniques to address the problem are very expensive. Changes to the land base will be on-going, so a methodology is required to fix the problem now and in future in the most efficient way.

Design Loader and Maintenance Tool (DLM) | we-do-IT - Spatia | we-do-IT

The Design Loader and Maintenance Tool (DLM Tool) has been developed to produce temporary Landbase information based upon proposed subdivision information. This process includes loading the DXF files, transforming them to the correct shape for the local coordinate system and fixing this data into place. A standard format for every DXF file needs to be established which defines which layers will be provided and what data is on each layer.


SIAS Toolkit | we-do-IT - Spatial Information Technology Con | we-do-IT

The SIAS Development Kit has been built using GE Networks Solutions' Smallworld Internet Application Server technology that allows a client to access and query AM/FM data across the Internet using universal standards, including HTTP, XML, GML and CGI scripts. SIAS Development Kit is distributed in a "base" functional configuration containing a set of generic, core features generally applicable to all customer sites.
