Basic Examples (4) 

Create a mesh region for Mount Everest:

In[1]:=

Out[1]=

Create a mesh region for a set of disks around a set of positions:

In[2]:=

Create a mesh region for Hawaii:

In[3]:=

Out[3]=

Create a mesh region for the United States:

In[4]:=

Out[4]=

Scope (3) 

Create a mesh for Hawaii,clipped at the polygon edge:

Create a mesh for Hawaii, but extend the data out to 200 miles, including bathymetry data:

Elevations below sea level can be removed using ProjectedRegion and BaseElevation:

In[8]:=

Out[8]=

Options (7) 

BaseElevation (1) 

"BaseElevation" can be used together with "ProjectedRegion"→False to ignore elevations below a specified threshold:

In[9]:=

Out[9]=

In[10]:=

Out[10]=

GeoModel (1) 

Specify regions for other geomodels:

In[11]:=

Out[11]=

GeoZoomLevel (1) 

Generate meshes with different resolutions:

In[12]:=

Out[12]=

In[13]:=

Out[13]=

In[14]:=

Out[14]=

ProjectedRegion (2) 

By default, regions are projected onto a flat surface:

In[15]:=

Out[15]=

To maintain a spherical surface, "ProjectedRegion" can be set to False:

In[16]:=

Out[16]=

RegionType (1) 

Different types of regions can be constructed:

In[17]:=

Out[17]=

In[18]:=

Out[18]=

In[19]:=

Out[19]=

In[20]:=

Out[20]=

ScaleFactor (1) 

Specify vertical exaggeration:

In[21]:=

Out[21]=

In[22]:=

Out[22]=

In[23]:=

Out[23]=

In[24]:=

Out[24]=

Properties and Relations

GeoElevationRegion is similar to GeoElevationGraphics3D, but there are differences.

In[25]:=

Out[25]=

In[26]:=

Out[26]=

In[27]:=

Out[27]=

In[28]:=

Out[28]=

In addition, GeoElevationGraphics3D always generates elevations from a flat surface, but GeoElevationRegion allows the data to be with respect to a spherical Earth

Possible Issues (1) 

The number of polygons for the entire world is large for the smallest GeoZoomLevel:
