Find objects that lie within a polygon - Overlays (3)

In this third example on spatial analysis using Overlays in ‘Spatial Manager’ we will apply the “Intersect” operator. This operator determines the geometries that overlap in the Source and Overlay object groups. Anything that does not overlap is discarded from... more

Clip geometries by a geometric area - Overlays (2)

In this second post dealing with Overlays in ‘Spatial Manager’, we will analyze another interesting operator (Clip), which creates objects from the areas of the Source that overlap with the Overlay. Use Clip in order to find objects that lie... more

Erase polygon parts using overlay functions - Overlays (1)

This post starts a series dedicated to one of the most powerful geometric and data-driven analysis tools included in ‘Spatial Manager’: the Overlay command. There are several operators to apply in the Overlay function, but they always have in common... more

Create buffers around existing geometries

Among the spatial analysis tools included in ‘Spatial Manager’, the Buffer function allows you to generate Buffered polygons around point, linear (lines, polylines, etc.) or polygonal (boundaries) objects. Buffers have multiple applications to analyze objects and their relationship with their... more

Union of polygons with common data - Dissolve Polygons

It is often useful to create enveloping polygons from the union of other adjacent polygons that share some data in common. Among the many examples that could be detailed, for example, obtaining county or provincial boundaries from the boundaries of... more

Centroids and Polygons

It is very common that when handling polygonal spatial information (Parcels, Buildings, Zones, etc.), the polygon data is attached to its Centroid, a point element, usually inside the polygon, which concentrates its alphanumeric information. ‘Spatial Manager’ includes powerful tools to... more
