Adjust geometries to a base map
Rubber sheeting refers to a method in mapping and surveying where a map or spatial data is adjusted or “stretched” to align with a reference map or coordinate system. This process helps to fix distortions caused by differences in scale,... more
Rubber sheet, align geographically buildings, parcels, ... in your DWG
When working with data sets from different sources, there are often differences in alignment between elements. The SPMRUBBERSHEET command allows you to select base points and reference points to modify vertices in a non-uniform way, beyond a simple displacement, scaling,... more
Create polygons with holes or islands
In CAD, polygons are usually represented as closed polylines due to drafting processes. This may be a problem when representing, visualising or exporting to GIS formats (or even Google Earth). This post explains how to create polygons with holes, islands... more
