Import geometries

You can optimize geospatial products by using geometries in the processing of reconstructions and alignments. This topic describes the basic requirements for geometries in ArcGIS Reality Studio, the types of geometries that can be used, requirements specific to each geometry type, how to import geometries, and their role in the reconstruction and alignment processing.

Basic geometry requirements

All geometries must meet the following criteria:

• The geometry is of type polygon, and is stored as a feature class in a geodatabase or shapefile (.shp).

• All polygons are contained in a single layer.

• The geometry does not contain curved geometries.

• The polygons do not have self-intersections or duplicated vertices.

• The geometries have the same spatial reference as the other data used as input in a reconstruction or alignment.

There are three types of geometries with different purposes and requirements: region of interest geometries, water body geometries, and correction geometries.

Import a region of interest geometry

Region of interest geometries define a particular region of interest. Specifying a region of interest geometry prevents the processing of unnecessary data, minimizing total processing time and required storage. Region of interest geometries can be used in alignments or reconstructions.

To import a region of interest geometry, complete the following steps:

1. On the Home tab, click the Geometries drop-down menu and click Region of Interest.

   The Select a region of interest geometry dialog box appears.

2. Browse to the location of the region of interest geometry you want to import and select the file.
3. Click OK.

   Note:

   If the region of interest geometry doesn't have valid horizontal and vertical coordinate systems an Invalid spatial reference warning appears. Click OK and choose the correct horizontal and vertical coordinate systems. Click OK.

The region of interest geometry appears in the Project Tree pane in the Geometries group.

Import a water body geometry

Water bodies are challenging to reconstruct due to their reflectiveness, transparency, and nonstatic nature. Water body geometries delineate the border of water surfaces and are used in the processing of reconstructions to interpolate points within the enclosed areas based on the 3D coordinates of the geometry's polygon vertices.

Note:

Water body geometries must be 3D polygons, meaning all of their vertices must have a valid z value.

To import a water body geometry, complete the following steps:

1. On the Home tab, click the Geometries drop-down menu and click Water Body.

   The Select a water body geometry dialog box appears.

2. Browse to the location of the water body geometry you want to import and select the file.
3. Click OK.

   Note:

   If the water body geometry doesn't have valid horizontal and vertical coordinate systems an Invalid spatial reference warning appears. Click OK and choose the correct horizontal and vertical coordinate systems. Click OK.

The water body geometry appears in the Project Tree pane in the Geometries group.

Import a correction geometry

Correction geometries aid in the reconstruction of challenging surfaces such as glass buildings and heavily shadowed areas.

Note:

If a correction geometry and a water body geometry overlap, the correction geometry is used for interpolating points within the overlapped area.

To import a correction geometry, complete the following steps:

1. On the Home tab, click the Geometries drop-down menu and click Correction.

   The Select a correction geometry dialog box appears.

2. Browse to the location of the correction geometry you want to import and select the file.
3. Click OK.

   Note:

   If the correction geometry doesn't have valid horizontal and vertical coordinate systems an Invalid spatial reference warning appears. Click OK and choose the correct horizontal and vertical coordinate systems. Click OK.

The correction geometry appears in the Project Tree pane in the Geometries group.
